linux-yocto/4.1: qemuppc and qemumips build fixes

The v4.1.28 -stable update broke the build for some ppc and mips
platforms. We fix the errors by backporting a missing commit for
ppc:

  powerpc/tm: Abort syscalls in active transactions

And by reverting a commit for mips (rather than backporting more
changes to -mm):

  Revert "MIPS: Reserve nosave data for hibernation"
