Latest -git and -rc6 may not compile for i386.

 Hi Nick,

 This patch:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=53e86b91b7ae66d4c2757195cbd42e00d9199cf2;hp=dbdf65b1b7f8ec48bda1604cfea7ac09ce583d6b

 _Seems_ to break kernel compilation on i386 with the attached .config.

 I'm getting the following error in latest Linus tree and -rc6:

  CC      kernel/irq/handle.o

                 from include/asm/smp.h:17,
                 from include/linux/irq.h:14,
                 from kernel/irq/handle.c:10:

 Didn't tryied to revert the patch, but compiled ok with 2.6.14 and
with latest Linus tree with this patch:

diff --git a/include/asm-i386/acpi.h b/include/asm-i386/acpi.h
index df4ed32..106c1ac 100644

 #define COMPILER_DEPENDENT_UINT64  unsigned long long

 But it's not right, of course, because any cmpxchg() usage will get the same
error.

(note: I'm 'playing' with the attached .config for a long time, I'll not
get surprised if it 'corrupted' something, due to my brain-damaged hacks..)
