Patch from George G. Davis
As pointed out be Matthew Klahn <MKLAHN@motorola.com>, some sys_ipc()
call options require six args, e.g. SEMTIMEDOP. This patch adds an ARM sys_ipc_wrapper to save the sys_ipc() 'fifth' arg on the stack.

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
1635317fac) 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.

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.

Before:

handler: altstack is at 0x0804b000, ebp = 0x0804bc7c

handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
handler: i387 unmasked precision exception, rounded up
After:
$ fpsig

handler: altstack is at 0x0804b000, ebp = 0x0804bc7c

Instead of using a global spinlock to protect the state
of the remote TLB flush use a lock and state for each sending CPU.
To tell the receiver where to look for the state use 8 different
call vectors. Each CPU uses a specific vector to trigger flushes on other
CPUs. Depending on the received vector the target CPUs look into
the right per cpu variable for the flush data.
When the system has more than 8 CPUs they are hashed to the 8 available
vectors. The limited global vector space forces us to this right now.
In future when interrupts are split into per CPU domains this could be
fixed, at the cost of needing more IPIs in flat mode.
Also some minor cleanup in the smp flush code and remove some outdated
debug code.
Requires patch to move cpu_possible_map setup earlier.
