Laurent Vivier d71a6d7332 NBD: add partition support
Permit the use of partitions with network block devices (NBD).

A new parameter is introduced to define how many partition we want to be able
to manage per network block device.  This parameter is "max_part".

For instance, to manage 63 partitions / loop device, we will do:

   [on the server side]
# nbd-server 1234 /dev/sdb
   [on the client side]
# modprobe nbd max_part=63
# ls -l /dev/nbd*

# nbd-client localhost 1234 /dev/nbd0
Negotiation: ..size = 80418240KB
bs=1024, sz=80418240

-------NOTE, RFC: partition table is not automatically read.
The driver sets bdev->bd_invalidated to 1 to force the read of the partition
table of the device, but this is done only on an open of the device.
So we have to do a "touch /dev/nbdX" or something like that.
It can't be done from the nbd-client or nbd driver because at this
level we can't ask to read the partition table and to serve the request
at the same time (-> deadlock)

If someone has a better idea, I'm open to any suggestion.

-------NOTE
On "nbd-client -d", we can do an iocl(BLKRRPART) to update partition table:
as the size of the device is 0, we don't have to serve the partition manager
request (-> no deadlock).

Laurent Vivier 48cf6061b3 NBD: allow nbd to be used locally
This patch allows Network Block Device to be mounted locally (nbd-client to
nbd-server over 127.0.0.1).

It creates a kthread to avoid the deadlock described in NBD tools
documentation.  So, if nbd-client hangs waiting for pages, the kblockd thread
can continue its work and free pages.

I have tested the patch to verify that it avoids the hang that always occurs
when writing to a localhost nbd connection.  I have also tested to verify that
no performance degradation results from the additional thread and queue.

Patch originally from Laurent Vivier.

Add a kernel parameter option to 'edd' to enable/disable BIOS Enhanced Disk
Drive Services.  CONFIG_EDD_OFF disables EDD while still compiling EDD into
the kernel.  Default behavior can be forced using 'edd=on' or 'edd=off' as

Corey Minyard bda4c30aa6 ipmi: run to completion fixes
The "run_to_completion" mode was somewhat broken.  Locks need to be avoided in
run_to_completion mode, and it shouldn't be used by normal users, just
internally for panic situations.

This patch removes locks in run_to_completion mode and removes the user call
for setting the mode.  The only user was the poweroff code, but it was easily
converted to use the polling interface.

Andres Salomon 3ef0e1f8ca x86: olpc: add One Laptop Per Child architecture support
This adds support for OLPC XO hardware.  Open Firmware on XOs don't contain
the VSA, so it is necessary to emulate the PCI BARs in the kernel.  This also
adds functionality for running EC commands, and a CONFIG_OLPC.

A number of OLPC drivers depend upon CONFIG_OLPC.

olpc_ec_timeout is a hack to work around Embedded Controller bugs.

Jan Engelhardt c9e587abfd vt: fix background color on line feed
A command that causes a line feed while a background color is active,
such as

	perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"'
and
	perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"'

causes the line that was started as a result of the line feed to be completely
filled with the currently active background color instead of the default
color.

When scrolling, part of the current screen is memcpy'd/memmove'd to the new
region, and the new line(s) that will appear as a result are cleared using
memset.  However, the lines are cleared with vc->vc_video_erase_char, causing
them to be colored with the currently active background color.  This is
different from X11 terminal emulators which always paint the new lines with
the default background color (e.g.  `xterm -bg black`).

The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new
vc->vc_scrl_erase_char is introduced with contains the erase character used
for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

Rik van Riel 5045bcae0f sysrq: add show-backtrace-on-all-cpus function
SysRQ-P is not always useful on SMP systems, since it usually ends up showing
the backtrace of a CPU that is doing just fine, instead of the backtrace of
the CPU that is having problems.

This patch adds SysRQ show-all-cpus(L), which shows the backtrace of every
active CPU in the system.  It skips idle CPUs because some SMP systems are
just too large and we already know what the backtrace of the idle task looks
like.

Document that the driver will use tpacpi as a short hand where necessary,

Also, register a module alias with the shorthand.  One can refer to the

Henrique de Moraes Holschuh 2d5e94d7ca ACPI: thinkpad-acpi: rate-limit CMOS/EC unsynced error messages
If userspace applications mess with the CMOS NVRAM, or something causes
both the ACPI firmware and thinkpad-acpi to try to change the brightness at
the same time, it is possible to have the CMOS and EC registers for the
current brightness go out of sync.

Should that happen, thinkpad-acpi could be really obnoxious when using a
brightness_mode of 3 (both EC and CMOS).  Instead of complaining a massive
number of times, make sure to complain only once until EC and CMOS are back
in sync.

Henrique de Moraes Holschuh 9288902225 ACPI: thinkpad-acpi: warn once about weird hotkey masks
thinkpad-acpi knows for a while now how to best program the hotkeys by
default, and always enable them by default.  Unfortunately, this
information has not filtered down everywhere it needs to, yet.  Notably,
old ibm-acpi documentation and most "thinkpad setup guides" will have wrong
information on this area.

Warn the local admin once whenever any of the following patterns are met:

1. Attempts to set hotkey mask to 0xffff (artifact from docs and config
   for the old ibm-acpi driver and behaviour).  This mask makes no
   real-world sense;

2. Attempts to set hotkey mask to 0xffffffff, which means the user is
   trying to just have "everything work" without even reading the
   documentation, or that we need to get a bug report, because there
   is a new thinkpad out there with new exciting hot keys :-)

3. Attempts to set hotkey mask to 0xffffff, which is almost never the
   correct way to set up volume and brightness event reporting (and with
   the current state-of-the-art, it is known to never be right way to do
   it).

The driver will perform any and all requested operations, though,
regardless of any warnings.  I hope these warnings can be removed one or
two years from now.

Henrique de Moraes Holschuh b59727965d ACPI: thinkpad-acpi: BIOS backlight mode helper (v2.1)
Lenovo ThinkPads with generic ACPI backlight level control can be easily
set to react to keyboard brightness key presses in a more predictable way
than what they do when in "DOS / bootloader" mode after Linux brings
up the ACPI interface.

The switch to the ACPI backlight mode in the firmware is designed to be
safe to use only as an one way trapdoor.  One is not to force the firmware
to switch back to "DOS/bootloader" mode except by rebooting.  The mode
switch itself is performed by calling any of the ACPI _BCL methods at least
once.

When in ACPI mode, the backlight firmware just issues (standard) events for
the brightness up/down hot key presses along with the non-standard HKEY
events which thinkpad-acpi traps, and doesn't touch the hardware.

thinkpad-acpi will:

1. Place the ThinkPad firmware in ACPI backlight control mode
   if one is available
2. Suppress HKEY backlight change notifications by default
   to avoid double-reporting when ACPI video is loaded when
   the ThinkPad is in ACPI backlight control mode
3. Urge the user to load the ACPI video driver

The user is free to use either the ACPI video driver to get the brightness
key events, or to override the thinkpad-acpi default hotkey mask to get
them from thinkpad-acpi as well (this will result in duplicate events if
ACPI video is loaded, so let's hope distros won't screw this up).

Provided userspace is sane, all should work (and *keep* working), which is
more that can be said about the non-ACPI mode of the new Lenovo ThinkPad
BIOSes when coupled to current userspace and X.org drivers.

Full guidelines for backlight hot key reporting and use of the
thinkpad-acpi backlight interface have been added to the documentation.

This patch removes a use of "idx" in pnp_check_port() and similar
functions, in preparation for replacing idx with a pointer to the

I split this out because it changes the behavior slightly: we used
to check for conflicts only with earlier resources, e.g., we checked
resource 2 against resources 0 and 1 but not against 3, 4, etc.  Now
we will check against all resources except 2.

Since resources are assigned in ascending order, the old behavior
was probably safe, but I don't like to depend on that ordering.

Bjorn Helgaas 2cd1393098 PNP: remove unused interfaces using pnp_resource_table
Rene Herman <rene.herman@gmail.com> recently removed the only in-tree
driver uses of:

    pnp_init_resource_table()
    pnp_manual_config_dev()
    pnp_resource_change()

in this change:

    http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f

These are no longer used in the PNP core either, so we can just remove
them completely.

It's possible that there are out-of-tree drivers that use these
interfaces.  They should be changed to either (1) use PNP quirks
to work around broken hardware or firmware, or (2) use the sysfs
interfaces to control resource usage from userspace.

Tejun Heo 87340e9834 libata-scsi: improve rbuf handling for simulated commands
Buffer length handling in simulated commands is error-prone and full
of bugs.  There are a number of places where necessary length checks
are missing and if the output buffer is passed in as sglist, nothing
works.

This patch adds a static buffer ata_scsi_rbuf which is sufficiently
large to handle the larges output from simulated commands (4k
currently), let all simulte functions write to the buffer and removes
all length checks as we know that there always is enough buffer space.
Copying in (for ATAPI inquiry fix up) and out are handled by
sg_copy_to/from_buffer() behind ata_scsi_rbuf_get/put() interface
which handles sglist properly.

This patch is inspired from buffer length check fix patch from Petr
Vandrovec.

Updated to use sg_copy_to/from_buffer() as suggested by FUJITA
Tomonori.

TBIPA needs to be set to a value (on connected MDIO buses) that

we were preventing boards with PHYs at 0x1f from working properly.
Instead, scan the bus when it comes up, and find an address that
doesn't have a PHY on it.  The TBI PHY configuration code then
trusts that the value in TBIPA is either safe, or doesn't matter
(ie - it's not an active bus with other PHYs).

Sergei Shtylyov 7b255436df siimage: coding style cleanup (take 2)
Fix 18 errors and several warnings given by checkpatch.pl:

- use of C99 // comments;

- trailing whitespace;

- 'switch' and 'case' not at the same indentation level;

- no space before the open parenthesis of the 'if' and 'switch' statements;

- space between function name and open parenthesis (though I have introduced
  such warnins in some places since the code looks prettier with the spaces);

- including <asm/io.h> instead of <linux/io.h>;

- line over 80 characters.

In addition to these changes, also do the following:

- make the arrays in sil_set_pio_mode() 'static', and make the arrays in
  sil_set_dma_mode() 'static const';

- change the string of the 'if' statements into the 'switch' statement in
  sil_pata_udma_filter();

- drop the needless '==' operators from the 'if' statements where a condition
  is a mere bit test;

- remove needless initializer for the 'tmp' variable in init_chipset_siimage();

- beautify groups of the variable initializers and assignment operators;

- add new line after variable definitions;

- remove new line between the comment and the statements it refers to;

- remove needless curly braces and parentheses;

- fix typos, capitalize acronyms, etc. in the comments...

It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the
availability of an asm/ide.h

It turns out this was done for ARM, and we can simply always select 
HAVE_IDE on ARM instead of manually tracking which platforms might 
possible have an IDE controller directly or indirectly.

Bartlomiej Zolnierkiewicz 165701d9fc siimage: add sil_* I/O ops
Add sil_iowrite{8,16,32}() and sil_ioread{8,16}() helpers, then use them to
merge code accessing configuration registers through PCI and MMIO together.

[ because of this SATA initialization bits from setup_mmio_siimage() are
  moved to init_chipset_siimage() ]

This also cuts code size a bit:

   text    data     bss     dec     hex filename
   4437     164       0    4601    11f9 drivers/ide/pci/siimage.o.before
   3979     164       0    4143    102f drivers/ide/pci/siimage.o.after

While at it:

* Use I/O ops directly instead of using ->IN{B,W} and ->OUT{B,W}.

* Fixup CodingStyle in setup_mmio_siimage().

* Rename 'tmpbyte' variable to 'tmp' in init_chipset_siimage().

Darrick J. Wong e8628dd06d [CPUFREQ] expose cpufreq coordination requirements regardless of coordination mechanism
Currently, affected_cpus shows which CPUs need to have their frequency
coordinated in software.  When hardware coordination is in use, the contents
of this file appear the same as when no coordination is required.  This can
lead to some confusion among user-space programs, for example, that do not
know that extra coordination is required to force a CPU core to a particular
speed to control power consumption.

To fix this, create a "related_cpus" attribute that always displays the
coordination map regardless of whatever coordination strategy the cpufreq
driver uses (sw or hw).  If the cpufreq driver does not provide a value, fall
back to policy->cpus.

Sergei Shtylyov fcbd3b4b92 [MIPS] Pb1200/DBAu1200: move platform code to its proper place
Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:

- change 'au1200_ide0_' variable name prefix to the mere 'ide_';

- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
  name of the chip used on the boards;

- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
  on-board devices;

- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
  the macros describing the Ethernet chip for consistency with the IDE
  macros;

- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is

Linus Walleij 26eed9a5c6 [ARM] 5022/1: Race in ARM MMCI PL18x driver, V2
Updated version of 4446/1. This also drops the suggested comparison
of host_remain for == 0, since that doesn't make sense (still works
for us, too). We have verified that this patch solve race problems
on atleast 2 archs at high frequencies.

(Verbatim copy of old patch text below.)

The patch below fixes a race condition in the ARM MMCI PL18x driver.

If new data arrives in the FIFO while existing data is being read then
we get a second iteration of the loop in mmci_pio_read.

However host->size is not updated until after mmci_pio_read returns,
so we get count = number of new bytes PLUS number of bytes already
copied in the first iteration. This results in a FIFO underrun as
we try and read mode data than is available.

The fix is to compensating for data read on previous iterations
when calculating the amount of data in the FIFO.

Nick Andrew d7a420c947 raid: remove leading TAB on printk messages
MD drivers use one printk() call to print 2 log messages and the second line
may be prefixed by a TAB character.  It may also output a trailing space
before newline.  klogd (I think) turns the TAB character into the 2 characters
'^I' when logging to a file.  This looks ugly.

Instead of a leading TAB to indicate continuation, prefix both output lines
with 'raid:' or similar.  Also remove any trailing space in the vicinity of
the affected code and consistently end the sentences with a period.

Dan Williams 8b3e6cdc53 md: introduce get_priority_stripe() to improve raid456 write performance
Improve write performance by preventing the delayed_list from dumping all its
stripes onto the handle_list in one shot.  Delayed stripes are now further
delayed by being held on the 'hold_list'.  The 'hold_list' is bypassed when:

  * a STRIPE_IO_STARTED stripe is found at the head of 'handle_list'
  * 'handle_list' is empty and i/o is being done to satisfy full stripe-width
    write requests
  * 'bypass_count' is less than 'bypass_threshold'.  By default the threshold
    is 1, i.e. every other stripe handled is a preread stripe provided the
    top two conditions are false.

Benchmark data:
System: 2x Xeon 5150, 4x SATA, mem=1GB
Baseline: 2.6.24-rc7
Configuration: mdadm --create /dev/md0 /dev/sd[b-e] -n 4 -l 5 --assume-clean
Test1: dd if=/dev/zero of=/dev/md0 bs=1024k count=2048
  * patched:  +33% (stripe_cache_size = 256), +25% (stripe_cache_size = 512)

Test2: tiobench --size 2048 --numruns 5 --block 4096 --block 131072 (XFS)
  * patched: +13%
  * patched + preread_bypass_threshold = 0: +37%

Changes since v1:
* reduce bypass_threshold from (chunk_size / sectors_per_chunk) to (1) and
  make it configurable.  This defaults to fairness and modest performance
  gains out of the box.
Changes since v2:
* [neilb@suse.de]: kill STRIPE_PRIO_HI and preread_needed as they are not
  necessary, the important change was clearing STRIPE_DELAYED in
  add_stripe_bio and this has been moved out to make_request for the hang
  fix.
* [neilb@suse.de]: simplify get_priority_stripe
* [dan.j.williams@intel.com]: reset the bypass_count when ->hold_list is
  sampled empty (+11%)
* [dan.j.williams@intel.com]: decrement the bypass_count at the detection
  of stripes being naturally promoted off of hold_list +2%.  Note, resetting
  bypass_count instead of decrementing on these events yields +4% but that is
  probably too aggressive.
Changes since v3:
* cosmetic fixups

Controller and with the attached patch the framebuffer comes up.  I have
tested it a bit with DirectFB to make sure it is working stable.

I also have an Intel Mobile GM945 and I compared the results, the programming
interface of the 9xx series from Intel is mostly the same, so I think the
patch should add all the functionality which the 945GM has.

York Sun 9b53a9e28a fbdev: powerpc: driver for Freescale 8610 and 5121 DIU
The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs

All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0.  Changing pixel clock has no effect
on other fbs.

Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0

required command line parameters to preallocate memory for frame buffer diufb.

optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:

Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60

Bpp
bpp=32, bpp=24, or bpp=16

Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS

Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.

If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

Andres Salomon 3553a2fa8c OLPC: gxfb/lxfb: add DCON panel modes to framebuffer drivers
Since there's no way to autodetect panel modes, we're forced to hardcode them
in the driver and add a big fat #ifdef.  The OLPC DCON needs a specific mode
line (at 1200x900).  This adds it to both gxfb and lxfb.

(Jordan said: We could probably detect the panel mode, but there isn't any
reason to since the panel timings are well known and won't change.  While OFW
detection would be good computer science fu, it would be a wasted effort since
its so easy to hard code them into the table.)

Andres Salomon f694e53bd0 lxfb: add power management functionality
This adds the ability to suspend/resume the lxfb driver, which includes:
  - Register and palette saving code; registers are stored in lxfb_par.
    A few MSR values are saved as well.
  - lx_powerup and lx_powerdown functions which restore/save registers and
    enable/disable graphic engines.
  - lxfb_suspend/lxfb_resume

Originally based on a patch by Jordan Crouse.

Nicolas Ferre fd0858017e atmel_lcdfb: wiring BGR to RGB color mode
Adds different wiring mode for the LCD screen.

The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead
"RGB-565".  The major part of graphic stacks for embedded systems uses only
"RGB-565".  It is possible to swap LCD IOs instead of doing this bit swapping
by software (See application note AT91SAM9 LCD Controller
http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf)

This wire swapping is done on the at91sam9rl-ek board (board code
using this patch will come later).

Haavard Skinnemoen 01d3a5e7fa atmel_lcdfb: don't initialize a pre-allocated framebuffer
If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.

Therefore, we should only initialize the framebuffer if we allocated it
ourselves.  This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e.  the user didn't provide a fixed
address or the reservation failed.

I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.

Andres Salomon b6f448e99c PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switch
Prior to suspend, we allocate and switch to a new VT; after suspend, we switch
back to the original VT.  This can be slow, and is completely unnecessary if
the framebuffer we're using can restore video properly.

This adds a hook that allows drivers to select whether or not to do this vt
switch, and changes the gxfb driver to call this hook.  It also adds a module
param to gxfb to allow controlling of the vt switch (defaulting to no switch).

(Note: I'm not convinced that console_sem is the best way to protect this, but
we should probably have some form of locking..)

Andres Salomon fa20c8a6e5 gxfb: replace FBSIZE config option with a module parameter
Use a command line option (vram) rather than hardcoding the vram size.  LxFB
already does this; it's useful for machines that can't query the BIOS for fb
size.  This patch originated from David Woodhouse, was modified by Jordan
Crouse, and was then modified further by me.

This also adds some gxfb documentation in Documentation/fb.

Jordan Crouse f0a0c1f20f gxfb: set the right registers to tweak the sync polarity
While running in flatpanel mode it is important to change the FP sync bits (VG
register 0x408) rather then the CRT sync bits (VG register 0x008).  This patch
keeps the CRT sync bits at default when a flatpanel exists.

Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie,
vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

This cleans up a few MSR-using drivers in the following manner:
  - Ensures MSRs are all defined in asm/geode.h, rather than in misc
    places
  - Makes the naming consistent; cs553[56] ones begin with MSR_,
    GX-specific ones start with MSR_GX_, and LX-specific ones start
    with MSR_LX_.  Also, make the names match the data sheet.
  - Use MSR names rather than numbers in source code
  - Document the fact that the LX's MSR_PADSEL has the wrong value
    in the data sheet.  That's, uh, good to note.

host endianness this flag will be overwritten by FBINFO_BE_MATH internal flag,
or cleared.

Michal Januszewski 6b745b6fd0 fbdev: make the best-fit section of fb_find_mode return the closest matching mode
Currently, if a perfect match in terms of resolution is not found,
fb_find_mode() only looks for a best-fit mode among modes with a higher
resolution than the one requested.  Thus, if the user requests a resolution
higher than the largest supported one, they are dropped to the default mode
(usually a low resolution one).

Change this behaviour so that all valid video modes are considered when
looking for a best-fit mode, while still preferring modes with a higher
resolution.

Anton Vorontsov 8d0aab2f16 gpiolib: dynamic gpio number allocation
If gpio_chip->base is negative during registration, gpiolib performs dynamic
base allocation.  This is useful for devices that aren't always present, such
as GPIOs on hotplugged devices rather than mainboards.  (This behavior was
previously specified but not implemented.)

To avoid using any numbers that may have been explicitly assigned but not yet
registered, this dynamic allocation assigns GPIO numbers from the biggest
number on down, instead of from the smallest on up.

Guennadi Liakhovetski 438d8908b3 gpiolib: better rmmod infrastructure
As long as one or more GPIOs on a gpio chip are used its driver should not be
unloaded.  The existing mechanism (gpiochip_remove failure) doesn't address
that, since rmmod can no longer be made to fail by having the cleanup code
report errors.  Module usecounts are the solution.

Assuming standard "initialize struct to zero" policies, this change won't
affect SOC platform drivers.  However, drivers for external chips (on I2C and
SPI busses) should be updated if they can be built as modules.
