Patch from Marc Singer

Add generic ARMv4T ID entry, remove ARM920 specific ID cache type
entry.

flag (and order it on SMP), so that del_timer_sync() always sees the
timer either pending or running if it is active.

My earlier change broke the if_ptr assumption used by SPPP drivers.
This makes sealevel driver do if_ptr like it used to.

In 2.6.0-test6, I put in a patch which fixed sealevel driver, but broke
all the other wan devices because it got rid of one level of indirection.

This puts back the indirection, and hopefully prevents others from
misreading it the same way. The SPPP drivers expect that
netdev->priv points to device local structure whose first element
is a pointer to the ppp device. 

Patch from Horms <horms@vergenet.net>

Since both the primay and the backup sync daemon can be started in a box
at a time, we must just check if the MASTER bit is set in the sync state.

This fixes the stack end detection properly, and verifies that the
stack content printing does not overflow into the next page even
partially.

This is required especially for x86 BIOSes that misalign the stack,
together with the page access debugging that unmaps unused kernel
pages to check for valid accesses.

Architectures with special needs (eg HPPA with stacks that grow up)
can override the kernel stack end test with __HAVE_ARCH_KSTACK_END
if they ever enable the anal slab debugging code.

This is the minimal change to make "mlockall()" not complain about
the occasional PROT_NONE area.

PROT_NONE is commonly used on x86-64, and is no reason to not lock
in the rest of the mappings into memory.

Sun-3: Add missing include (needed because of __attribute_used__ in
<linux/init.h>)

M68k: Export missing symbol csum_partial

 - add disallow_signal() to complement allow_signal(), rather than
   having different subsystems try to do it by hand.

 - add a version of dequeue_signal() which does the necessary locking on
   its own, again to avoid having modules have to care.

 - let allow_signal() to actually allow signals other than
   SIGKILL. Currently they get either converted to SIGKILL or
   silently dropped, according to whether your kernel thread
   happens to have sa_handler set for the signal in question.

   (Barf alert: we do this by just installing a dummy handler)

 - make jffs2 use the cleaned up infrastructure

From Pavel Machek. Make software suspend compile again on x86-64

It can have gotten set by a stray interrupt if there were
no handlers while the IRQ was disabled, and we shouldn't
confuse other parts (ie this is another safety-net for the
issues that Al Viro brought up about disable_irq() deadlocks
when no handlers exist).

This fixes a bug which was introduced when the code was switched to use
atomic_read()s.

The bug prevents hot-unplugging of SCSI (or emulated SCSI) devices from
working. 

From Patrick Mansfield.

They can happen on x86 as a result of interrupts in BIOS calls.

jiffies based values to ms. This fix crazy key repeat on ADB
based PowerMacs

use a NULL "driver" pointer and actually try to call it after
casting it !

properly with HZ != 100, causing tb_to_us to be wrong and gettimeofday()
to return strangely "off" results

core99 dual G4s).

registers exist on common CPUs and without those definitions, SMP won't
build

without this, you get no display on machines with those cards

so that the kernel boots at least on POWER4 and G5 CPUs

the coff image to randomly fail

 - Implement write-buffer flushing by garbage collection instead of padding.
 - Implement selective write-buffer flushing on fsync(). 
 - Implement error recovery on write-buffer flush.
 - Fix remove_suid(). Writing to a suid file didn't previously mark the file non-suid.
 - Fix handling of full file systems, to avoid unlink() returning -ENOSPC.
 - Fix assorted memory leaks.
 - Improve garbage collection efficiency by merging fewer pages.
