Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
"Resurrect Alchemy platforms by invoking the WAIT instructions with
interrupts enabled. This still leaves the race condition between
testing TIF_NEED_RESCHED and the WAIT instruction for Alchemy
platforms which need a different fix than other MIPS platforms. But
at least it gets MIPS platforms flying again.
There are also fixes for two build errors (CONFIG_FTRACE=y with
CONFIG_DYNAMIC_FTRACE=n) and CONFIG_VIRTUALIZATION without CONFIG_KVM"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: ftrace: Add missing CONFIG_DYNAMIC_FTRACE
MIPS: include: mmu_context.h: Replace VIRTUALIZATION with KVM
MIPS: Alchemy: fix wait function
