Note that asm/fixmap.h is an x86-ism that isn't present in many other
architectures, so this hunk will break the build.
To make progress with these patches I've fixed it up with an ugly #ifdef
CONFIG_X86, but it needs a real solution instead before this can be pushed
upstream.
I also saw an error on x86 tip on special configuration. I found this
new patch below to be a good solution to both.
Let me know what you think.
=====
This patch aligns MODULES_END to the beginning of the Fixmap section.
It optimizes the space available for both sections. The address is
pre-computed based on the number of pages required by the Fixmap
section.
It will allow GDT remapping in the Fixmap section. The current
MODULES_END static address does not provide enough space for the kernel
to support a large number of processors.

The patch is heavily whitespace and line wrap damaged :-(
Please send a properly titled, changelogged delta patch against tip:master (or
tip:x86/mm) to remove the CONFIG_X86 hack and fix the build bug.
Thanks,
Ingo
