Hi Paul,

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) failed like this:

arch/x86/kernel/cpu/amd.c: In function 'bsp_init_amd':
arch/x86/kernel/cpu/amd.c:437:3: error: 'va_align' undeclared (first use in this function)
arch/x86/kernel/cpu/amd.c:438:23: error: 'ALIGN_VA_32' undeclared (first use in this function)
arch/x86/kernel/cpu/amd.c:438:37: error: 'ALIGN_VA_64' undeclared (first use in this function)

Caused by the module.h split up intreacting with commit dfb09f9b7ab0
("x86, amd: Avoid cache aliasing penalties on AMD family 15h") from the
tip tree.

I have added the following patch for today (this, or something similar,
could be applied to the tip tree directly - the export.h include below
was added by the module.h splitup).
