the attached patch fixes the scheduler's migration thread startup bug that
got unearthed by Rusty's recent CPU-startup enhancements.

the fix is to let a startup-helper thread migrate the migration thread,
instead of the migration thread calling set_cpus_allowed() itself.
Migrating a not running thread is a simple and robust thing, and needs no
cooperation from migration threads - thus the catch-22 problem of how to
migrate the migration threads is solved finally.

the patch is against Rusty's initcall fix/hack which calls
migration_init() before other CPUs are brought up - this ordering is
clearly the clean way of doing migration init. [the patch also fixes a UP
compiliation bug in Rusty's hack.]

As pointed out by Andrew Morton, this fixes:
	softirq.c: In function `spawn_ksoftirqd':
	softirq.c:416: warning: statement with no effect

This patch fixes the calls to initialize ksoftirqd and the
migration threads.  This really should be done by the initcall
depends patch.

 The check in do_alignment_ldmstm for addr and eaddr being the same is #ifdef'd
out for the ARM922T because they aren't expected to be the same due to the 
different way the MMU sets addr. The ARM920T is just a 922T with more cache, 
and should be treated the same. I've checked on a real ARM920T and it does 
complain loudly every time it fixes up a misaligned ldm/stm unless this 
patch is applied.
 I suspect that the ARM926 should be treated the same way as well, but I can't
find any relevant documentation on ARM's web-site, so have left it out. 

Remove a couple of needless includes from system3.c, and update
mach-types file.

free_pages() oopses if page->mapping is non-NULL.  Ensure that any
rmap datastructures for the page are freed before freeing the
concerned page.

This covers the changes Dominik's made to the core cpufreq code.

Someone included mach-types.h into asm/arch/hardware.h, which causes
the whole kernel to needlessly rebuild when the machine type file is
updated.  Move mach-types.h include into the files that really need
it.

ARM can use the generic rmap.h.  It doesn't need its own version.

This improves interrupts and exceptions returning to user space
by a few of cycles.  We change the requirements for
*_restore_user_regs slightly so we can remove a few instructions.
We also re-shuffle the code to handle pending work.

irq_enter/irq_exit no longer take arguments.  We also use the
x86 methods for hardirq.h and softirq.h; they're sufficient
for ARM.

These macros are no longer required; the generic versions
defined in sched.c are sufficient for ARM.

Replace local_save_flags_cli with local_irq_save.  Remove duplicate
cli, sti, save_flags and restore_flags definitions.

Since we have a signed 32-bit time_t, the fact that y % 4 == 0
will get it wrong in 2100 is irrelevant.

This could be made more efficient by batching the hashtable
flushes but that can be done later.

We were missing an element in the old_serial_port structure.

The following two patches seem to be needed to export the requisite
symbols needed for fully modular builds of the new serial drivers in
2.5.28.

The old form of designated initializers are obsolete: we need to
replace them with the ISO C forms before 2.6.  Gcc has always
supported both forms anyway.

From Rusty's Trivial Patch - thanks.

Trying to open a non-present port (for configuration) causes us to
to endlessly loop (by returning -ERESTARTSYS).  We should be returning
success.  This cset fixes this.

This patch add Wake-on-LAN support to the 8139cp ethernet driver.

It also converts the gccism "foo: bar" to the C99 ".foo = bar" syntax.

the attached patch fixes a comment that got incorrect via the
set_thread_area() changes.

This modifies the PPC boot sequence to "plug in" CPUs one at a
time.

This modifies the i386 boot sequence to "plug in" CPUs one at a
time.  This is the minimal change to make it work (the CPUs are
brought up as normal during the "smp_prepare_cpus()" probe phase).
