0b6dd8a640 [WATCHDOG] s3c2410_wdt exit driver via labels
Cleanup the s3c2410_wdt driver's exit point by
using labels instead of multiple returns. Also
remove the checks for the resources having been
allocate in the exit, as we will now either have
fully allocated or not allocated the resources
at-all.

1d6bb8e51d drm: Unify radeon offset checking.
Replace r300_check_offset() with generic radeon_check_offset(), which doesn't
reject valid offsets when the framebuffer area is at the very end of the card's
32 bit address space. Make radeon_check_and_fixup_offset() use
radeon_check_offset() as well.

5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

3cec556a84 [PATCH] n_r3964: Use struct pid to track user space clients
Currently this driver tracks user space clients it should send signals to.  In
the presenct of file descriptor passing this is appears susceptible to
confusion from pid wrap around issues.

Replacing this with a struct pid prevents us from getting confused, and
prepares for a pid namespace implementation.

5fcf7bb73f [PATCH] read_zero_pagealigned() locking fix
Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel
bugzilla 7645.  Right: read_zero_pagealigned uses down_read of mmap_sem,
but another thread's racing read of /dev/zero, or a normal fault, can
easily set that pte again, in between zap_page_range and zeromap_page_range
getting there.  It's been wrong ever since 2.4.3.

The simple fix is to use down_write instead, but that would serialize reads
of /dev/zero more than at present: perhaps some app would be badly
affected.  So instead let zeromap_page_range return the error instead of
BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in
that case - there's no need to optimize for it.

Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of
zeromap_page_range), though it really isn't interesting there.  And since
mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that
than -ENOMEM.

64bb6c5e1d [PATCH] tty_ioctl: use termios for the old structure and termios2 for the new
Having split out the user and kernel structures it turns out that some non
glibc C libraries pull their termios struct from the kernel headers
directly or indirectly.  This means we must keep "struct termios" as the
library sees it correct for the old ioctls.  Not a big problem just shuffle
the names and ifdef around a bit

This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

edc6afc549 [PATCH] tty: switch to ktermios and new framework
This is the core of the switch to the new framework.  I've split it from the
driver patches which are mostly search/replace and would encourage people to
give this one a good hard stare.

The references to BOTHER and ISHIFT are the termios values that must be
defined by a platform once it wants to turn on "new style" ioctl support.  The
code patches here ensure that providing

1. The termios overlays the ktermios in memory
2. The only new kernel only fields are c_ispeed/c_ospeed (or none)

the existing behaviour is retained.  This is true for the patches at this
point in time.

Future patches will define BOTHER, ISHIFT and enable newer termios structures
for each architecture, and once they are all done some of the ifdefs also
vanish.

24ec839c43 [PATCH] tty: ->signal->tty locking
Fix the locking of signal->tty.

Use ->sighand->siglock to protect ->signal->tty; this lock is already used
by most other members of ->signal/->sighand.  And unless we are 'current'
or the tasklist_lock is held we need ->siglock to access ->signal anyway.

(NOTE: sys_unshare() is broken wrt ->sighand locking rules)

Note that tty_mutex is held over tty destruction, so while holding
tty_mutex any tty pointer remains valid.  Otherwise the lifetime of ttys
are governed by their open file handles.  This leaves some holes for tty
access from signal->tty (or any other non file related tty access).

It solves the tty SLAB scribbles we were seeing.

(NOTE: the change from group_send_sig_info to __group_send_sig_info needs to
       be examined by someone familiar with the security framework, I think
       it is safe given the SEND_SIG_PRIV from other __group_send_sig_info
       invocations)

4d7cbac7c8 [PATCH] IPMI: Fix BT long busy
The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets.  The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy.  The subdriver now issues
a "Get BT Capabilities" command and properly uses those results.  More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers.  Finally, indent and
other style quirks were normalized.

the ipmi_si driver would request flags, see if the event buffer full flag was

5d469ec0f4 [PATCH] Correct misc_register return code handling in several drivers
Clean up several code points in which the return code from misc_register is
not handled properly.

Several modules failed to deregister various hooks when misc_register fails,
and this patch cleans them up.  Also there are a few modules that legitimately
don't care about the failure status of misc register.  These drivers however
unilaterally call misc_deregister on module unload.

Since misc_register doesn't initialize the list_head in the init_routine if it
fails, the deregister operation is at risk for oopsing when list_del is
called.  The initial solution was to manually init the list in the miscdev
structure in each of those modules, but the consensus in this thread was to
consolodate and do that universally inside misc_register.

66c669baa7 [AGP] Allocate AGP pages with GFP_DMA32 by default
Not all graphic page remappers support physical addresses over the 4GB
mark for remapping, so while some do (the AMD64 GART always did, and I
just fixed the i965 to do so properly), we're safest off just forcing
GFP_DMA32 allocations to make sure graphics pages get allocated in the
low 32-bit address space by default.

AGP sub-drivers that really care, and can do better, could just choose
to implement their own allocator (or we could add another "64-bit safe"
default allocator for their use), but quite frankly, you're not likely
to care in practice.

So for now, this trivial change means that we won't be allocating pages
that we can't map correctly by mistake on x86-64.

[ On traditional 32-bit x86, this could never happen, because GFP_KERNEL
  would never allocate any highmem memory anyway ]

7d915a3898 [AGP] Fix intel 965 AGP memory mapping function
This introduces a i965-specific "mask_memory()" function that knows
about the extended physical addresses that the i965 supports.  This
allows us to correctly map in physical memory in the >4GB range into the
GTT.

Also simplify/clean-up the i965 case for the aperture sizing by just
returning the fixed 512kB size from "fetch_size()".  We don't really
care that not all of the aperture may be visible - the only thing that
cares about the aperture size is the Intel "stolen memory" calculation,
which depends on the fixed size.

65f27f3844 WorkStruct: Pass the work_struct pointer instead of context data
Pass the work_struct pointer to the work function rather than context data.
The work function can use container_of() to work out the data.

For the cases where the container of the work_struct may go away the moment the
pending bit is cleared, it is made possible to defer the release of the
structure by deferring the clearing of the pending bit.

To make this work, an extra flag is introduced into the management side of the
work_struct.  This governs auto-release of the structure upon execution.

Ordinarily, the work queue executor would release the work_struct for further
scheduling or deallocation by clearing the pending bit prior to jumping to the
work function.  This means that, unless the driver makes some guarantee itself
that the work_struct won't go away, the work function may not access anything
else in the work_struct or its container lest they be deallocated..  This is a
problem if the auxiliary data is taken away (as done by the last patch).

However, if the pending bit is *not* cleared before jumping to the work
function, then the work function *may* access the work_struct and its container
with no problems.  But then the work function must itself release the
work_struct by calling work_release().

In most cases, automatic release is fine, so this is the default.  Special
initiators exist for the non-auto-release case (ending in _NAR).

52bad64d95 WorkStruct: Separate delayable and non-delayable events.
Separate delayable work items from non-delayable work items be splitting them
into a separate structure (delayed_work), which incorporates a work_struct and
the timer_list removed from work_struct.

The work_struct struct is huge, and this limits it's usefulness.  On a 64-bit
architecture it's nearly 100 bytes in size.  This reduces that by half for the
non-delayable type of event.

a number of small patches:
- include notifier.h include file
- re-arrange prototype functions
- remove =0 initializations
- change printk logging levels to what's used in other drivers
- /dev/watchdog is a VFS so use nonseekable_open

  we prefer "if (function_or_variable op constant)"
- arg is a __user pointer
- use MAX_TIMEOUT_SECONDS instead of 32 in WDIOC_SETTIMEOUT

The root cause is the device struct is initialized twice.

If the device is allocated dynamically by platform_device_alloc,
platform_device_alloc will initialize struct device, then,
platform_device_add should be used to register the device.

The difference between platform_device_register and platform_device_add is
platform_device_register will initiate the device while platform_device_add
won't.

A wrong function was being used to free a list; this fixes the problem.

28af24bb84 [AGPGART] Fix up misprogrammed bridges with incorrect AGPv2 rates.
Some dumb bridges are programmed to disobey the AGP2 spec.
This is likely a BIOS misprogramming rather than poweron default, or
it would be a lot more common.

AGPv2 spec 6.1.9 states:

 "The RATE field indicates the data transfer rates supported by this
  device. A.G.P. devices must report all that apply."

Fix them up as best we can.

This will prevent errors like..

agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.
agpgart: req mode 1f000201 bridge_agpstat 1f000a14 vga_agpstat 2f000217.
