Geert Uytterhoeven d1a35e4d74 m68k: Disable Amiga serial console support if modular
If CONFIG_AMIGA_BUILTIN_SERIAL=m, I get the following warnings:

| drivers/char/amiserial.c: At top level:
| drivers/char/amiserial.c:2138: warning: data definition has no type or storage class
| drivers/char/amiserial.c:2138: warning: type defaults to 'int' in declaration of 'console_initcall'
| drivers/char/amiserial.c:2138: warning: parameter names (without types) in function declaration
| drivers/char/amiserial.c:2134: warning: 'amiserial_console_init' defined but not used

because console_initcall() is not defined (nor really sensible) in the
modular case.

So disable serial console support if the driver is modular.

Francois Romieu e383d56487 r8169: revert "read MAC address from EEPROM on init"
This reverts commit 7bf6bf4803.

The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1.  It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.

Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.

Alistair John Strachan 4777e4e6b8 hwmon: (abituguru3) Cosmetic whitespace fixes
As the probable result of zealous copy/pasting, many supported boards
contain sensor names with trailing whitespace. Though this is not a
huge problem, it is inconsistent with other sensor names, and with
other similar hwmon drivers.

Additionally, the DMI nag message added in 2.6.27 was missing a
space between two sentence fragments -- might as well clean that up
too.

Doesn't alter any kernel text, just data.

Jean Delvare 97ae60bb38 hwmon: (lm90) Add support for the LM99 16 degree offset
The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.

Jean Delvare ec38fa2b35 hwmon: (lm90) Fix handling of hysteresis value
There are several problems in the way the hysteresis value is handled
by the lm90 driver:

* In show_temphyst(), specific handling of the MAX6646 is missing, so
  the hysteresis is reported incorrectly if the critical temperature
  is over 127 degrees C.
* In set_temphyst(), the new hysteresis register value is written to
  the chip but data->temp_hyst isn't updated accordingly, so there is
  a short period of time (up to 2 seconds) where the old hystereris
  value will be returned while the new one is already active.
* In set_temphyst(), the critical temperature which is used as a base
  to compute the value of the hysteresis register lacks
  device-specific handling. As a result, the value of the hysteresis
  register might be incorrect for the ADT7461 and MAX6646 chips.

Fix these 3 bugs.

Jay Fenlason cd1f70fdb4 firewire: fw-sbp2: fix races
1: There is a small race between queue_delayed_work() and its
   corresponding kref_get().  Do the kref_get first, and _put it again
   if the queue_delayed_work() failed, so there is no chance of the
   kref going to zero while the work is scheduled.
2: An SBP2_LOGOUT_REQUEST could be sent out with a login_id full of
   garbage.  Initialize it to an invalid value so we can tell if we
   ever got a valid login_id.
3: The node ID and generation may have changed but the new values may
   not yet have been recorded in lu and tgt when the final logout is
   attempted.  Use the latest values from the device in
   sbp2_release_target().

Stefan Richter 0dcfeb7e3c firewire: fw-sbp2: delay first login to avoid retries
This optimizes firewire-sbp2's device probe for the case that the local
node and the SBP-2 node were discovered at the same time.  In this case,
fw-core's bus management work and fw-sbp2's login and SCSI probe work
are scheduled in parallel (in the globally shared workqueue and in
fw-sbp2's workqueue, respectively).  The bus reset from fw-core may then
disturb and extremely delay the login and SCSI probe because the latter
fails with several command timeouts and retries and has to be retried
from scratch.

We avoid this particular situation of sbp2_login() and fw_card_bm_work()
running in parallel by delaying the first sbp2_login() a little bit.

This is meant to be a short-term fix for
https://bugzilla.redhat.com/show_bug.cgi?id=466679.  In the long run,
the SCSI probe, i.e. fw-sbp2's call of __scsi_add_device(), should be
parallelized with sbp2_reconnect().

Problem reported and fix tested and confirmed by Alex Kanavin.

The recent commit 2fca5ccf97 ("libata:
switch to using block layer tagging support") to enable support for
block layer tagging in libata was broken for non-NCQ devices

The block layer initializes the tag field to -1 to detect invalid uses
of a tag, and if the libata devices does NOT support NCQ, we just used
that field to index the internal command list.  So we need to check for
-1 first and only use the tag field if it's valid.

Zhao, Yu a491913ff2 PCI: remove unused resource assignment in pci_read_bridge_bases()
This cleanup removes the resource assignment in pci_read_bridge_bases()
since it has taken care by pci_alloc_child_bus() when allocating the bus:

        /* Set up default resource pointers and names.. */
        for (i = 0; i < PCI_BRIDGE_RES_NUM; i++) {
                child->resource[i] = &bridge->resource[PCI_BRIDGE_RESOURCES+i];
                child->resource[i]->name = child->name;
        }

The original ARI support code has a compatibility problem with non-ARI
devices.  If a device doesn't support ARI, turning on ARI forwarding on
its upper level bridge will cause undefined behavior.

This fix turns on ARI forwarding only when the subordinate devices
support it.

Kenji Kaneshige d2174c3c07 PCI hotplug: cpqphp: fix kernel NULL pointer dereference
The following patch fixes the regression in 2.6.27 that causes kernel
NULL pointer dereference at cpqphp driver probe time.  This patch should
be backported to the .27 stable series.

Seems to have been introduced by
f46753c5e3.

The root cause of this problem seems that cpqphp driver calls
pci_hp_register() wrongly. In current implementation, cpqphp driver
passes 'ctrl->pci_dev->subordinate' as a second parameter for
pci_hp_register(). But because hotplug slots and it's hotplug controller
(exists as a pci funcion) are on the same bus, it should be
'ctrl->pci_dev->bus' instead.

This was another merge problem that wasn't a data conflict, but due to
independent changes in two branches that just didn't work together.

The pcc-acpi staging driver used

	acpi_driver_data(device) = hotkey;

to set driver data, but the ACPI merge made that invalid in commit
db89b4f0db ("ACPI: catch calls of
acpi_driver_data on pointer of wrong type"), and now you're supposed to
just do.

	device->driver_data = hotkey;

instead.

Alan Stern d4c9b73608 [SCSI] sd: remove command-size switching code
This patch (as1138) removes from sd.c some old code for switching from
10-byte commands to 6-byte commands.  This code is redundant -- the
switching for READ and WRITE is already handled in
scsi_io_completion() and the switching for MODE SENSE is already
handled in scsi_mode_sense().  (There is no comparable switch for MODE
SELECT, but I doubt one is needed.)

Furthermore the other handlers do a better job; they check for
appropriate ASC and ASCQ values before blindly switching the size.
The code in sd.c is known to cause problems with some devices by
switching when it shouldn't.

Jamie Wellnitz 10dab22664 [SCSI] sd: Fix handling of NO_SENSE check condition
The current handling of NO_SENSE check condition is the same as
RECOVERED_ERROR, and assumes that in both cases, the I/O was fully
transferred.

We have seen cases of arrays returning with NO_SENSE (no error), but
the I/O was not completely transferred, thus residual set.  Thus,
rather than return good_bytes as the entire transfer, set good_bytes
to 0, so that the midlayer then applies the residual in calculating
the transfer, and for sd, will fail the I/O and fall into a retry
path.

Kiyoshi Ueda 6c5121b78b [SCSI] export busy state via q->lld_busy_fn()
This patch implements q->lld_busy_fn() for scsi mid layer to export
its busy state for request stacking drivers.

For efficiency, no lock is taken to check the busy state of
shost/starget/sdev, since the returned value is not guaranteed and
may be changed after request stacking drivers call the function,
regardless of taking lock or not.

When scsi can't dispatch I/Os anymore and needs to kill I/Os
(e.g. !sdev), scsi needs to return 'not busy'.
Otherwise, request stacking drivers may hold requests forever.

The problem is essentially caused by us eating UNIT_ATTENTION
conditions in scsi_test_unit_ready().  Fix by updating the ->changed
flag when this happens if the media is removable.

Herbert Xu b63365a2d6 net: Fix disjunct computation of netdev features
My change

    commit e2a6b85247
    net: Enable TSO if supported by at least one device

didn't do what was intended because the netdev_compute_features
function was designed for conjunctions.  So what happened was that
it would simply take the TSO status of the last constituent device.

This patch extends it to support both conjunctions and disjunctions
under the new name of netdev_increment_features.

It also adds a new function netdev_fix_features which does the
sanity checking that usually occurs upon registration.  This ensures
that the computation doesn't result in an illegal combination
since this checking is absent when the change is initiated via
ethtool.

The two users of netdev_compute_features have been converted.

Zhao Yakui 5eaff72218 ACPI: hack around sysfs warning with link order
There exists the following warning message will appear after the
following commit is merged.
   >commit f2e969acd6d5981e6b1272810002558650d0736e
   >Author: Zhao Yakui <yakui.zhao@intel.com>
   >Date:   Mon Aug 11 14:57:50 2008 +0800
    >ACPI: Add "acpi.power_nocheck=1" to disable power state check in
power transition:

   >WARNING: at linux-2.6/fs/sysfs/dir.c:463  sysfs_add_one+0x33/0x39()
   >sysfs: duplicate filename 'acpi' can not be created
   >kobject_add_internal failed for acpi with -EEXIST, don't try to register
            things with the same name in the same directory

   In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).

   In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
   workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.

   Of course the better solution is to fix it in generic param code related
with sysfs.

Keith Packard 9e44af790f drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operations
To synchronize clip lists with the X server, the DRM lock must be held while
looking at drawable clip lists. To synchronize with other ring access, the
ring mutex must be held while inserting commands into the ring.  Failure to
do the first resulted in easy visual corruption when moving windows, and the
second could have corrupted the ring with DRI2.

Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the
ring mutex means potentially sleeping. Deal with both of these by always
running the tasklet from a work handler.

Also, protect from clip list changes since the vblank request was queued by
making sure the window has at least one rectangle while looking inside,
preventing oopses .

Benjamin Herrenschmidt a1c19894b7 PCI: Workaround invalid P2P bridge bus numbers
Some firmware fail to properly configure P2P bridges, leaving them
with invalid bus numbers. In some cases, this happens on some embedded
4xx boards as the result of the kernel allocating different bus space
than the firmware does to host bridges while not setting
pcibios_assign_all_busses() for various reasons. In other cases, it can
just be bogus firmware.

This adds some sanity checking to the PCI probing code. If a bridge is
found whose primary bus number doesn't match the bus it's sitting on,
or whose secondary bus number not strictly above it's primary bus
number, then the bridge bus numbers are deconfigured in the first pass
of pci_scan_bridge() to be re-assigned in the second pass.

The PCI core now manages slot names on behalf of slot detection
and slot hotplug drivers, including the handling of duplicate

We can use the fakephp driver to help test the new functionality.
Add a 'dup_slots' module param to force fakephp to create multiple
slots with the same name. We can then verify that the PCI core
correctly renamed the slots.

Alex Chiang 5fe6cc6068 PCI: prevent duplicate slot names
Prevent callers of pci_create_slot() from registering slots with
duplicate names. This condition occurs most often when PCI hotplug
drivers are loaded on platforms with broken firmware that assigns
identical names to multiple slots.

We now rename these duplicate slots on behalf of the user.

If firmware assigns the name N to multiple slots, then:

	The first registered slot is assigned N
	The second registered slot is assigned N-1
	The third registered slot is assigned N-2
	etc.

This is the permanent fix mentioned in earlier commits d6a9e9b4 and
167e782e (shpchp/pciehp: Rename duplicate slot name...).

We take advantage of the new 'hotplug' parameter in pci_create_slot()
to prevent a slot create/rename race between hotplug drivers and
detection drivers.

	Scenario A:
	hotplug driver                  detection driver
	--------------                  ----------------
	pci_create_slot(hotplug=set)
					pci_create_slot(hotplug=NULL)

The hotplug driver creates the slot with its desired name, and then
releases the semaphore. Now, the detection driver tries to create
the same slot, but it already exists. We don't care about renaming,
so return the existing slot.

	Scenario B:
	hotplug driver                  detection driver
	--------------                  ----------------
					pci_create_slot(hotplug=NULL)
	pci_create_slot(hotplug=set)

The detection driver creates the slot with name "X". Then the hotplug
driver tries to create the same slot, but wants the name "Y" instead.
We detect that we're trying to create the same slot and that we also
want a rename, so rename the slot to "Y" and return.

	Scenario C:
	hotplug driver                  hotplug driver
	--------------                  ----------------
	pci_create_slot(hotplug=set)
					pci_create_slot(hotplug=set)

Two separate hotplug drivers are attempting to claim the slot and
are passing valid hotplug_slot args to pci_create_slot(). We detect
that the slot already has a ->hotplug callback, prevent a rename,
and return -EBUSY.

Alex Chiang 828f37683e PCI: update pci_create_slot() to take a 'hotplug' param
Slot detection drivers can co-exist with hotplug drivers. The names
of the detected/claimed slots may be different depending on module
load order.

For legacy reasons, we need to allow hotplug drivers to override
the slot name if a detection driver is loaded first (and they find
the same slots).

Creating and overriding slot names should be an atomic operation,
otherwise you get a locking nightmare as various drivers race to
call pci_create_slot().

pci_create_slot() is already serialized by grabbing the pci_bus_sem.

We update the API and add a 'hotplug' param, which is:

	set if the caller is a hotplug driver
	NULL if the caller is a detection driver

pci_create_slot() does not actually use the 'hotplug' parameter in this
patch. A later patch will add the logic that uses it.

Sheng Yang 8dd7f8036c PCI: add support for function level reset
Sometimes, it's necessary to enable software's ability to quiesce and
reset endpoint hardware with function-level granularity, so provide
support for it.

The patch implement Function Level Reset(FLR) feature following PCI-e
spec. And this is the first step. We would add more generic method, like
D0/D3, to allow more devices support this function.

The patch contains two functions. pcie_reset_function() is the new
driver API, and, contains some action to quiesce a device.  The other
function is a helper:  pcie_execute_reset_function() just executes the
reset for a particular device function.

Current the usage model is in KVM. Function reset is necessary for
assigning device to a guest, or moving it between partitions.

For Function Level Reset(FLR), please refer to PCI Express spec chapter
6.6.2.

Since the ehca device driver does not support dynamic memory add and

regions that cover all of memory being used by InfiniBand protocols in

The solution (for now at least) is to add a memory notifier to the
ehca device driver and if a request for dynamic memory add or remove
comes in, ehca will always reject it.  The user can add or remove
memory by hot-removing the ehca adapter, performing the memory
operation, and then hot-adding the ehca adapter back.

Henrique de Moraes Holschuh 75700e53cd ACPI: thinkpad-acpi: attempt to preserve fan state on resume
Attempt to preserve fan state across sleep and hibernation if the fan
control mode is enabled.

For safety reasons, only the PWM OFF (fan at 100%) or maximum
closed-loop level (level 7) are preserved.  If the fan state was set
to anything else, it will not be restored.

Also, should the fan be at PWM OFF mode at resume, it will be left at
that state (but this is extremely unlikely, no ThinkPad firmware was
ever reported to do this).

For reference, the known states used for fan control upon resume by
the firmware  are either "auto" or "level 7" depending on whether the
laptop wakes due to normal conditions or a thermal emergency.

the problem was that some older cards are mis-identified and didn't support
5GHz rates, while they have the right MAC & Synth chip.

This patch changes the way how p54 decides if it should enable 11a channels
or not.

Bob Copeland 8bdd5b9c6b ath5k: fix suspend-related oops on rmmod
Based on a patch by Elias Oltmanns, we call ath5k_init in resume even
if we didn't previously open the device.  Besides starting up the
device unnecessarily, this also causes an oops on rmmod because
mac80211 will not invoke ath5k_stop and softirqs are left running after
the module has been unloaded.  Add a new state bit, ATH_STAT_STARTED,
to indicate that we have been started up.

donald.d.dugger@intel.com 383d7a11c9 ACPI: Fix possible null ptr dereference
Code in `pci_link.c' is calling the internal routine `acpi_ut_evaluate_object'
which is dangerous given that it is passing a NULL pointer when it should
be passing a pointer to a real object.  The patch corrects the issue by
having the code call the external routine `acpi_evaluate_object', which
correctly handles a NULL pointer.

Zhao Yakui 39a0ad8710 ACPI : Load device driver according to the status of acpi device
According to ACPI spec when the status of some device is not present
but functional, the device is valid and the children of this device
should be enumerated. It means that the device should be added to
linux acpi device tree. But the device driver for this device should not
be loaded.
    The detailed info can be found in the section 6.3.7 of ACPI 3.0b spec.
    _STA may return bit 0 clear (not present) with bit 3 set (device is
functional). This case is used to indicate a valid device for which no
device driver should be loaded (for example, a bridge device.).
Children of this device may be present and valid. OS should continue
enumeration below a device whose _STA returns this bit combination

Zhao Yakui f5adfaa372 ACPI: Add "acpi.power_nocheck=1" to disable power state check in power transition
Maybe the incorrect power state is returned on the bogus bios, which
is different with the real power state. For example: the bios returns D0
state and the real power state is D3. OS expects to set the device to D0
state. In  such case if OS uses the power state returned by the BIOS and
checks the device power state very strictly in power transition, the device
can't be transited to the correct power state.

   So the boot option of "acpi.power_nocheck=1" is added to avoid checking
the device power in the course of device power transition.

power flag is power_managable. i.e. The device has the _PSx/_PRx object.

At the same time before the drivers/acpi/power module is loaded, there is no
relation between acpi_power_resource and acpi device. So the first parameter
of acpi_power_get_state is changed to acpi_handle.

Lin Ming 08237974af ACPI: replace AE_BAD_ADDRESS exception code with AE_ERROR
The AE_BAD_ADDRESS exception code is now unused in ACPICA.
For linux, it's only used at wmi.c and acer-wmi.c.
I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
has no special meaning. The parent functions just call AE_SUCCESS() or
AE_FAILURE() to check the return status.
So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.
