9c1729db3e Prevent an O_NDELAY writer from blocking when a tty write is blocked by the tty atomic writer mutex
Without this a tty write could block if a previous blocking tty write was
in progress on the same tty and blocked by a line discipline or hardware
event.  Originally found and reported by Dave Johnson.

mspec_mmap was setting VM_LOCKED (without adjusting locked_vm): don't do
that, it serves no purpose in 2.6, other than to mess up the locked_vm

7b595756ec sysfs: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

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.

679ce0ace6 random: fix output buffer folding

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.

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)

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.

9614ece14f [AGPGART] intel_agp: use table for device probe
Fixed issues noted by Christoph Hellwig, and I changed device table
scan a bit to allow the case that some models of graphics chips may
have same host bridge type. This type of chip will be added in the future.

This patch cleans up device probe function. Eric Anholt was the original author.

makes it clean. Eric Anholt wrote the original patch.

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().

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.

5f81941c9d [SPARC]: Mark as emulating cmpxchg, add appropriate depends for DRM.
The DRM code depends on an atomic version of cmpxchg(), which is not
available on sparc32. Since other platforms besides sparc32 have this
issue a KCONFIG option is added for it.
