linux-next x86 build fixes

[Luis R. Rodriguez]

Curious if the x86 symbol build issues are supposed to be resolved
already on linux-next as of today, if not, how's it looking to get
this fixed ? I am carrying around Adam's temporary patch "kbuild:
provide include/asm/asm-prototypes.h for x86" on top of linux-next but
each day I move on I keep seeing this is still not fixed and keep
having to carry it. Curious what the delays are to get this resolved,
the last thread I saw seemed to acknowledge the issue and that Nick
was working on a fix ?
