Use ".init.plt" section consistently, and mark plt sections executable.

This brings pci.ids in your BK tree in sync with my database.

I've merged changes from both 2.4 and 2.5 with direct submissions to my
repository and deleted a few entries which are obviously wrong.

"savesegment()" is declared in multiple places. Clean up and declare
it just once in <asm/system.h>

The attached patch fixes the crash top or cat /proc/*/wchan produces
when using KALLSYMS it's a buffer overrun that should not happen.

Based on patch by andi kleen.

Noted by Adrian Bunk and Adam Richter

This was originally added in rev 1.26.1.2, then dropped 
during a merge in rev 1.33.  Please be more careful with
those merges, people.

This patch adds support for enable/disable_irq_wake for the SA11x0
CPUs, allowing drivers or other code to select which IRQs are able
to wake the CPU from sleep mode.

This brings the ARM dma mapping functionality into line with
the current generic interface, allowing any struct device to
be passed into the dma_* functions.

Further cleanups will be possible when the USB layer is
converted to use the dma_* API.

RTH's final complaint (so far 8) was that we should sort the module
sections: archs might require some sections to be adjacent, so they can
all be reached by a relative pointer (ie.  GOT pointer).  This
implements that reordering, and simplfies the module interface for
architectures as well.

Previously an arch could specify it wanted extra space, but not where
that space would be.  The new method (used only by PPC so far) is to
allocate an empty section (in asm/module.h or by setting LDFLAGS_MODULE
to use an arch specific linker script), and expand that to the desired
size in "module_frob_arch_sections()".

From: Richard Henderson <rth@twiddle.net>

Richard points out that we should be using sh_addr to hold the address,

The original patch used to overload sh_offset to a pointer to the
location of the section.  This uses sh_addr, which is more correct
and less surprising.

As RTH pointed out, we use -fno-common for the kernel (otherwise we'd
have to sort out the small symbols anyway).

So the common section allocation in the module code is pointless.

Only set IRQ type after a successful request_irq().
Driver now known as sa1111-pcmcia in driverfs.

- Add missing include files.
- Fail to set pcmcia socket state for invalid socket numbers.
- Fix locla_ typo.
- Make pcmcia_jornada720_exit __devexit, not __exit.
- Don't initialise jornada720 machine specifics if not running
  on jornada720.

bios32.c uses outb(), and therefore should have asm/io.h included.

Add <asm/arch/iop310.h> include, needed for platform implementation of
architecture private __virt_to_bus / __bus_to_virt.

The semaphore initialisers were using the old gcc syntax.  Add
sema_count() implementation for the sa11x0 audio implementation.

I've been carrying this since Jan sent it out a month or two ago.
I don't know if anyone has tested it though.  The sort of people
who use quotas tend to like nice stable kernels.  I read through it,
but can't say that I know enough about quotas to know if it makes sense.
The wait_on_dquot() synchronisation is a bit odd.

I do need to do a round of stability testing with this and ext3 - the
interaction between quotas and ext3 is an area where we've had deadlocks
in the past.

But the quota locking is definitely looking crufty, and I'd suggest that
we run with this..


Patch from Jan Kara <jack@suse.cz>

"I'm resending you the patch with new quota SMP locking.  The patch removes
 BKL and replaces it with two spinlocks protecting quota lists and data
 stored in dquot structures.  Also non-SMP locking was changed a bit make SMP
 locking easier (eg.  we got rid of not very nice dq_dup_ref counters).  The
 patch is against 2.5.48 but applies well also to 2.5.49.  Would you please
 apply the patch?"


- Change dqoff_sem from a semaphore to an rwsem.

- Convert dqi_flags from an int to a ulong and use test_bit/set_bit rather
  thatn &/|

- The various exported quota operations now run without lock_kernel().
  This means that things like DQUOT_ALLOC_SPACE no longer take lock_kernel()
  in out high-perfomance filesystems.  Nice.

- Replace lock_kernel() in the quota code with two quota-private global
  locks.

- Replace all the open-coded waitqueue management with a semaphore
  (wait_on_dquot())
