We need to move even more stuff into the header so that folks can use

Most of the AGP changes recently have been done in lock-step with
DRM updates, so it's probably easier to have airlied pushing
AGP changes at the same time he does DRM updates.

Egmont Koblinger 1ed8a2b3c5 console UTF-8 fixes (fix)
Recently my console UTF-8 patch went mainline.  Here is an additional patch
that fixes two nasty issues and improves a third one, namely:

1. My patch changed the behavior if a glyph is not found in the Unicode
   mapping table. Previously for Unicode values less than 256 or 512 the
   kernel tried to display the glyph from that position of the glyph table,
   which could lead to a different accented letter being displayed. I
   removed this fallback possibility and changed it to display the
   replacement symbol.

   As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package)
   lack Unicode mapping information, hence all you get is lots of question
   marks. Though theoretically it's actually a user-space bug (the font
   should be fixed), Behdad and I both believe that it'd be good to work
   around in the kernel by re-introducing the fallback solution for ASCII
   characters only. This sounds a quite reasonable decision, since all fonts
   ship the ASCII characters in the first 128 positions. This way users
   won't be surprised by lots of question marks just because s/he issued a
   not-so-perfectly parameterized setfont command. As this fallback is only
   re-introduced for code points below 128, you still won't see an accented
   letter replaced by another, but at least you'll always get the English
   letters right.

2. My patch introduced "question mark with inverted color attributes" as a
   last resort fallback glyph. Though it perfectly works on VGA console, on
   framebuffer you may end up with question marks that are highlighed but
   shouldn't be, and normal characters that are accidentally highlighed.
   This is caused by missing FLUSHes when changing the color attribute.

3. I've updated the table of double-width character based on Markus's
   updated version. Only ten new code poings (one interval) is added.

Matt Mackall 679ce0ace6 random: fix output buffer folding
(As reported by linux@horizon.com)

Folding is done to minimize the theoretical possibility of systematic
weakness in the particular bits of the SHA1 hash output.  The result of
this bug is that 16 out of 80 bits are un-folded.  Without a major new
vulnerability being found in SHA1, this is harmless, but still worth
fixing.

Paul Fulghum 38ad2ed08d tty: restore locked ioctl file op
Restore tty locked ioctl handler which was replaced with
an unlocked ioctl handler in hung_up_tty_fops by the patch:

commit e10cc1df1d
Author: Paul Fulghum <paulkf@microgate.com>
Date:   Thu May 10 22:22:50 2007 -0700

    tty: add compat_ioctl

This was reported in:
[Bug 8473] New: Oops: 0010 [1] SMP

The bug is caused by switching to hung_up_tty_fops in do_tty_hangup.  An
ioctl call can be waiting on BLK after testing for existence of the locked
ioctl handler in the normal tty fops, but before calling the locked ioctl
handler.  If a hangup occurs at that point, the locked ioctl fop is NULL
and an oops occurs.

(akpm: we can remove my debugging code from do_ioctl() now, but it'll be OK to
do that for 2.6.23)

David Woodhouse f4d2781731 fix radeon setparam on 32/64 systems, harder.
Commit 9b01bd5b28 introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.

Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64.  And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.

Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386.  It would be a no-op with
compat_u64 anyway.

GMCH, it might have multiple graphic chip models, like 945GME case, so
we should be sure the detect works through the whole table.

Oleg Nesterov 040b6362d5 tty: fix leakage of -ERESTARTSYS to userland
Spotted by Satoru Takeuchi.

kill_pgrp(task_pgrp(current)) sends the signal to the current's thread
group, but can choose any sub-thread as a target for signal_wake_up().
This means that job_control() and tty_check_change() may return
-ERESTARTSYS without signal_pending().

Yoann Padioleau 632155e659 potential parse error in ifdef
I have made a tool to parse the kernel that does not pre-process the
source.  That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all).  So, my parser sometimes
reports parse error not originally detected by gcc.  Here is my (first)
patch.

Alexey Dobriyan e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig

Linus Torvalds faa8b6c3c2 Revert "ipmi: add new IPMI nmi watchdog handling"
This reverts commit f64da958df.

Andi Kleen is unhappy with the changes, and they really do not seem
worth it.  IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.

Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.

Paul Fulghum ae030e435f tty_set_ldisc() receive_room fix
Fix tty_set_ldisc in tty_io.c so that tty->receive_room is only cleared if
actually changing line disciplines.

Without this fix a problem occurs when requesting the line discipline to
change to the same line discipline.  In this case tty->receive_room is
cleared but ldisc->open() is not called to set tty->receive_room back to a
sane value.  The result is that tty->receive_room is stuck at 0 preventing
the tty flip buffer from passing receive data to the line discipline.

For example: a switch from N_TTY to N_TTY followed by a select() call for
read input results in data never being received because tty->receive_room
is stuck at zero.

A switch from N_TTY to N_TTY followed by a read() call works because the
read() call itself sets tty->receive_room correctly (but select does not).

Previously (< 2.6.18) this was not a problem because the tty flip buffer
pushed data to the line discipline without regard for tty->receive room.

Parag Warudkar 8e39c933b1 tpm: fix sleep-in-spinlock
flush_scheduled_work() can sleep, and we're calling it under spinlock.

AFAICS, moving flush_scheduled_work before spin_lock() should not cause any
problems.

Reason being - The only thing that can race against tpm_release is tpm_open
(tpm_release is called when last reference to the file is closed and only
thing that can happen after that is tpm_open??) and tpm_open acquires
driver_lock and more over it bails out with EBUSY if chip->num_opens is
greater than 0.

I also moved chip->num_pending-- to after deleting timer and setting data
pending as it looks more correct for the paranoid although it probably doesn't
matter as it is guarded by driver_lock.  None the less this change should not
cause problems.

While I was at it I noticed a missing NULL check in tpm_register_hardware
which is fixed with this patch as well.

Egmont Koblinger 2f1a2ccb9c console UTF-8 fixes
The UTF-8 part of the vt driver suffers from the following issues which are
addressed in my patch:

1) If there's no glyph found for a particular valid UTF-8 character, we try
   to display U+FFFD. However if this one is not found either, here's what
   the current kernel does:

   - First, if the Unicode value is less than the number of glyphs, use the
     glyph directly from that position of the glyph table. While it may be a
     good idea in the 8-bit world, it has absolutely no sense with Unicode
     in mind. For example, if a Latin-2 font is loaded and an application
     prints U+00FB ("u with circumflex", not present in Latin-2) then as a
     fallback solution the glyph from the 0xFB position of the Latin-2
     fontset (which is an "u with double accent" - a different character) is
     displayed.

   - Second, if this fallback fails too, a simple ASCII question mark is
     printed, which is visually undistinguishable from a real question mark.

   I changed the code to skip the first step (except if in non-UTF-8 mode),
   and changed the second step to print the question mark with inverse color
   attributes, so it is visually clear that it's not a real question mark,
   and resembles more to the common glyph of U+FFFD.

2) The UTF-8 decoder is buggy in many ways:

   - Lone continuation bytes (section 3.1 of Markus Kuhn's UTF-8 stress
     test) are not caught, they are displayed as some "random" (taken
     directly form the font table, see above) glyphs instead the replacement
     character.

   - Incomplete sequences (sections 3.2 and 3.3 of the stress test) emit no
     replacement character, but rather cause the subsequent valid character
     to be displayed more times(!).

   - The decoder is not safe: overlong sequences are not caught currently,
     they are displayed as if these were valid representations. This may
     even have security impacts.

   - The decoder does not handle D800..DFFF and FFFE..FFFF specially, it
     just emits these code points and lets it be looked up in the glyph
     table. Since these are invalid code points, I replace them by U+FFFD
     and hence give no chance for them to be looked up in the glyph table.
     (Assuming no font ships glyphs for these code points, this change is
     not visible to the users since the glyph shown will be the same.)

   With my fixes to the decoder it now behaves exactly as Markus Kuhn's
   stress test recommends.

3) It has no concept of double-width (CJK) characters. It's way beyond the
   scope of my patch to try to display them, but at least I think it's
   important for the cursor to jump two positions when printing such
   characters, since this is what applications (such as text editors)
   expect. Currently the cursor only jumps one position, and hence
   applications suffer from displaying and refreshing problems, and editing
   some English letters that are preceded by some CJK characters in the same
   line is a nightmare. With my patch an additional space is inserted after
   the CJK character has been printed (which usually means a replacement
   symbol of course). (If U+FFFD isn't availble and hence an inverse
   question mark is displayed in the first cell, I keep the inverted state
   for the space in the 2nd column so it's quite easy to see that they are
   tied together.)

4) There is a small built-in table of zero-width spaces that are not to be
   printed but silently skipped. U+200A is included there, but it's not a
   zero-width character, so I remove it from there.

  Currently dtlk doesn't check register_chrdev() failure correctly.
  register_chrdev() returns a errno on failure.

- check probe failure

  dtlk ignores probe failure and allows the module loading without
  such device. I got "Trying to free nonexistent resource" message
  by release_region() when unloading module without device.

Christoph Hellwig 1eeb66a1bb move die notifier handling to common code
This patch moves the die notifier handling to common code.  Previous
various architectures had exactly the same code for it.  Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)

arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at.  avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

Eric W. Biederman 98a27ba485 tty: introduce no_tty and use it in selinux
While researching the tty layer pid leaks I found a weird case in selinux when
we drop a controlling tty because of inadequate permissions we don't do the
normal hangup processing.  Which is a problem if it happens the session leader
has exec'd something that can no longer access the tty.

We already have code in the kernel to handle this case in the form of the
TIOCNOTTY ioctl.  So this patch factors out a helper function that is the
essence of that ioctl and calls it from the selinux code.

This removes the inconsistency in handling dropping of a controlling tty and
who knows it might even make some part of user space happy because it received
a SIGHUP it was expecting.

In addition since this removes the last user of proc_set_tty outside of
tty_io.c proc_set_tty is made static and removed from tty.h

Gerd Hoffmann 69331af79c Fixes and cleanups for earlyprintk aka boot console
The console subsystem already has an idea of a boot console, using the
CON_BOOT flag.  The implementation has some flaws though.  The major
problem is that presence of a boot console makes register_console() ignore
any other console devices (unless explicitly specified on the kernel
command line).

This patch fixes the console selection code to *not* consider a boot
console a full-featured one, so the first non-boot console registering will
become the default console instead.  This way the unregister call for the
boot console in the register_console() function actually triggers and the
handover from the boot console to the real console device works smoothly.
Added a printk for the handover, so you know which console device the
output goes to when the boot console stops printing messages.

The disable_early_printk() call is obsolete with that patch, explicitly
disabling the early console isn't needed any more as it works automagically
with that patch.

I've walked through the tree, dropped all disable_early_printk() instances
found below arch/ and tagged the consoles with CON_BOOT if needed.  The
code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf).

Changes to last version: Rediffed against -rc3, adapted to mips cleanups by
Ralf, fixed "udbg-immortal" cmd line arg on powerpc.

tested it with 2.6.19 and the driver works fine again with a Cyclades-Z on
an Athlon 64 X2.

Prarit Bhargava ee527cd3a2 Use stop_machine_run in the Intel RNG driver
Replace call_smp_function with stop_machine_run in the Intel RNG driver.

CPU A has done read_lock(&lock)
CPU B has done write_lock_irq(&lock) and is waiting for A to release the lock.

A third CPU calls call_smp_function and issues the IPI.  CPU A takes CPU
C's IPI.  CPU B is waiting with interrupts disabled and does not see the
IPI.  CPU C is stuck waiting for CPU B to respond to the IPI.

Deadlock.

The solution is to use stop_machine_run instead of call_smp_function
(call_smp_function should not be called in situations where the CPUs may be
suspended).

Corey Minyard ee6cd5f8f5 ipmi: allow shared interrupts
The IPMI driver used enable_irq and disable_irq when it got into situations
where it couldn't allocate memory; it did this to avoid having the interrupt
just lock the machine when it couldn't get memory to perform the transaction
to disable the interrupt.

This patch modifies the driver to not use disable_irq and enable_irq.  It
instead sends the messages to the BMC to perform this operation.  It also
makes sure interrupts are cleanly disabled when the interface is shut down and
cleans up some shutdown things that are no longer necessary.

Jean Delvare 6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Oliver Neukum 82eab1306c [AGPGART] prevent probe collision of sis-agp and amd64_agp
For some vendor/id pairs the kernel will autoload both the sis-agp and the
amd64_agp modules as the sis-agp module will load for all sis devices.
This collision causes the bug reported in:
http://bugzilla.novell.com/show_bug.cgi?id=248665

As currently sis_probe does its own matching, requesting the whole range
gains nothing.  The clean fix seems to me to leave the matching to the core
and advertise only the devices actually supported.  This patch does so.

Alexey Dobriyan fb8f7ba077 [WATCHDOG] Semi-typical watchdog bug re early misc_register()
It seems that some watchdog drivers are doing following mistake:

	rv = misc_register();
	if (rv < 0)
		return rv;
	rv = request_region();
	if (rv < 0) {
		misc_deregister();
		return rv;
	}

But, right after misc_register() returns, misc device can be opened and
ioctls interacting with hardware issued, and driver can do outb() to
port it doesn't own yet, because request_region() is still pending.

Here is my patch, compile-tested only.
