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
In file included from include/asm/fixmap.h:28,

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

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..)
