Patch from Richard Purdie
This patch cleans up the PXA Poodle platform code removing an unneeded
static iomap. It also corrects errors in the platform header file and
adds a missing GPIO define.

Patch from Lennert Buytenhek
It's silly to have I2C enabled in all ixp2000 defconfigs but not to
have the ixp2000 bus driver enabled in any of them. This patch enables
CONFIG_I2C_IXP2000 for all in-tree ixp2000 boards.

Commit 66759a01adbfe8828dd063e32cf5ed3f46696181 introduced the fix for
time ticking too fast on some boards by disabling one of the doubly
connected timer pins on ATI boards.
However, it ends up being _much_ too broad a brush, and that just makes
some other ATI boards not work at all since they now have no timer
source.
So disable the automatic ATI southbridge detection, and just rely on
people who see this problem disabling it by hand with the option
"disable_timer_pin_1" on the kernel command line.
Maybe somebody can figure out the proper tests at a later date.

Pavel Emelianov and Kirill Korotaev observe that fs and arch users of
security_vm_enough_memory tend to forget to vm_unacct_memory when a
failure occurs further down (typically in setup_arg_pages variants).
These are all users of insert_vm_struct, and that reservation will only
be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some
cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't.
So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into
Committed_AS each time they're run. But don't add VM_ACCOUNT to them,
it's inappropriate to reserve against the very unlikely case that gdb
be used to COW a vDSO page - we ought to do something about that in
do_wp_page, but there are yet other inconsistencies to be resolved.
The safe and economical way to fix this is to let insert_vm_struct do
the security_vm_enough_memory check when it finds VM_ACCOUNT is set.
And the MIPS irix_brk has been calling security_vm_enough_memory before
calling do_brk which repeats it, doubly accounting and so also leaking.
Remove that, and all the fs and arch calls to security_vm_enough_memory:
give it a less misleading name later on.

Masked FPU exceptions should obviously not happen in the first place,
but if they do, ignoring them seems to be the right thing to do.
Although there is no documentation available for Cyrix MII, I did find
erratum F-7 for Winchip C6, "FPU instruction may result in spurious
exception under certain conditions" which seems to indicate that this
can happen.
That would also explain the behaviour Ondrej Zary reported on the MII.

My patch "Separate pci bits out of struct device_node" (commit
1635317facea3094ddf34082cd86797efb1d9f7e) had the unfortunate
side-effect that it stopped eeh_init() from working correctly.
It needs the pointers set up by find_and_init_phbs(), but it was being
called just before find_and_init_phbs(). That meant that we didn't
enable EEH (pSeries PCI error recovery) on any devices, and that meant
that on POWER5 systems, the hypervisor wouldn't let us enable memory or
I/O space access to any devices, and their drivers got somewhat
confused.
This fixes it by moving the eeh_init call after find_and_init_phbs.
Tested on a POWER5 partition.

Akita Support
Add the platform support code for two new Sharp Zaurus Models, Spitz
(SL-C3000) and Borzoi (SL-C3100).
This patch also adds most of the foundations for Akita (SL-C1000) Support.
The missing link for Akita is the driver for its I2C io expander. Once this
has been finished, the missing Kconfig option and machine declaration can
easily be added to this code.

The same LCD is present on both the Sharp Zaurus c7x0 series and the cxx00 but
with different framebuffer drivers (w100fb vs. pxafb). This patch adds
support for the cxx00 series to the LCD driver. It also adds some LCD to
touchscreen interface logic needed by the touchscreen driver to prevent
interference problems, the idea being to keep all the ugly code in one place
leaving the drivers themselves clean. sharpsl.h is used to provide the
abstraction.

Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to
the c7x0 series yet different. This patch series abstracts the differences
and generates a set of common drivers that support both series of devices. It
then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100). Hooks
for Akita (SL-C1000) differences are also added. The I2C driver for its IO
expander is the only missing piece.
This patch:
Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so
that other models such as the cxx00's can share it. Create sharpsl.h which
will be used to abstract machine/model specifics.
This enables the driver to be used by the Zaurus cxx00 series.

Discard *.exit.text sections on runtime. We cannot do this on link time
because of the way BUG macros are implemented. If "__exit function" calls
one of those macros, __bug_table section will reference this function.
This is similar to ".altinstructions" situation on i386.
*.exit.data seems to be OK in this respect and is discarded on link
time.

This is the same patch that went into i386 just before 2.6.13
came out. I still can't build 64-bit user apps, so I tested
with program (see below) in 32-bit mode on 64-bit kernel:
Before:
$ fpsig
handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown]
handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
handler: i387 unmasked precision exception, rounded up
After:
$ fpsig
handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result]
handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
handler: i387 unmasked precision exception, rounded up

annotations in many low-level x86_64 routines, plus a config option
