As the first step in consolidating the pseries hotplug cpu code,
create platforms/pseries/hotplug-cpu.c and move rtas_stop_self()
into it. Do the rtas token initialisation in a new initcall, rather
than rtas_initialize().

This patch makes paging_init() use highend_pfn/highstart_pfn globals.
It removes the need of 'high' local which was needed only by HIGHMEM config.
More important perhaps, it fixes a bug when HIGHMEM is set but there's
actually no physical highmem (highend_pfn = 0)

While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve
things it didn't resolve all the problems. So bite the bullet and discard
.exit.text and .exit.data at runtime. Which of course sucks because it
bloats binaries with code that will never ever be used but it's the only
thing that will work reliable as demonstrated by the function sd_major() in
drivers/scsi/sd.c.
Gcc may compile sd_major() using a jump table which it will put into
.rodata. If it also inlines sd_major's function body into exit_sd() which
gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld
to discard exit_sd's code at link time. However sd_major happens to
contain a switch statement which gcc will compile using a jump table in
.rodata on the architectures I checked. So, when ld later discards
.exit.text only the jump table in .rodata with its stale references to
the discard .exit.text will be left which any no antique ld will honor
with a link error.

The driver is usable on the newer SAM9 processors so replace all text
references to AT91RM9200 with just AT91.
The controller bug where all the words are byte-swapped is fixed on the
AT91SAM9 processors. The byte-swapping work-around therefore only needs
to be done if cpu_is_at91rm9200().
[Original patch from Wojtek Kaniewski]
The AT91RM9200 and AT91SAM9260 processors support two MMC/SD slots - the
slot which is connected is now passed via the platform_data and the
correct slot selected in the AT91_MCI_SDCR register.
The driver should not be calling at91_set_gpio_output() since the VCC
pin should have already been configured as an output in the
processor/board setup code. The driver should call
at91_set_gpio_value().

Fix sizing of big_bytes in the case of vlan frames. The 4
VLAN_HLEN bytes were omitted, leading to sizing the big buffer
4 bytes smaller than it should be. Due to how rx buffers are
carved from pages, this was harmless for the common (9000, 1500)
byte MTUs, but could lead to data corruption for some MTUs.

As reported by Andy Whitcroft, at least the SLES9 initrd build process
depends on getting the kernel version from the kernel binary. It does
that by simply trawling the binary and looking for the signature of the
"linux_banner" string (the string "Linux version " to be exact. Which
is really broken in itself, but whatever..)
That got broken when the string was changed to allow /proc/version to
change the UTS release information dynamically, and "get_kernel_version"
thus returned "%s" (see commit a2ee8649ba6d71416712e798276bf7c40b64e6e5:
"[PATCH] Fix linux banner utsname information").
This just restores "linux_banner" as a static string, which should fix
the version finding. And /proc/version simply uses a different string.
To avoid wasting even that miniscule amount of memory, the early boot
string should really be marked __initdata, but that just causes the same
bug in SLES9 to re-appear, since it will then find other occurrences of
"Linux version " first.

- relbranch_fixup(), for non-branches, would end up setting
regs->tnpc incorrectly, in fact it would set it equal to
regs->tpc which would cause that instruction to execute twice
Also, if this is not a PC-relative branch, we should just
leave regs->tnpc as-is. This covers cases like 'jmpl' which
branch to absolute values.
- To be absolutely %100 safe, we need to flush the instruction
cache for all assignments to kprobe->ainsn.insn[], including
cases like add_aggr_kprobe()
- prev_kprobe's status field needs to be 'unsigned long' to match
the type of the value it is saving
- jprobes were totally broken:
= jprobe_return() can run in the stack frame of the jprobe handler,
or in an even deeper stack frame, thus we'll be in the wrong
register window than the one from the original probe state.
So unwind using 'restore' instructions, if necessary, right
before we do the jprobe_return() breakpoint trap.
= There is no reason to save/restore the register window saved
at %sp at jprobe trigger time. Those registers cannot be
modified by the jprobe handler. Also, this code was saving
and restoring "sizeof (struct sparc_stackf)" bytes. Depending
upon the caller, this could clobber unrelated stack frame
pieces if there is only a basic 128-byte register window
stored on the stack, without the argument save area.
So just saving and restoring struct pt_regs is sufficient.
= Kill the "jprobe_saved_esp", totally unused.
Also, delete "jprobe_saved_regs_location", with the stack frame
unwind now done explicitly by jprobe_return(), this check is
superfluous.
