Note that these conflicts will arise once you merge x86-asm-for-linus,
with an additional semantic conflict in arch/x86/crypto/blake2s-core.S,
see my merge conflict mail to that pull request.

This asm/pgtable_32_types.h conflict will be the only conflict you'll see
when you merge x86-iopl-for-linus:

<<<<<<< HEAD
#define CPU_ENTRY_AREA_PAGES (NR_CPUS * 39)
=======
#define CPU_ENTRY_AREA_PAGES (NR_CPUS * 41)
>>>>>>> e3cb0c7102f04c83bf1a7cb1d052e92749310b46

And the correct resolution is to pick the '41' side.

Thanks,

Ingo
