Hi Greg,

These are missing patches from the initial powerpc spectre backports for 4.4.
Please queue them as well if you don't have any objections.

Thanks,

Diana Craciun (8):
  powerpc/fsl: Enable runtime patching if nospectre_v2 boot arg is used
  powerpc/fsl: Flush branch predictor when entering KVM
  powerpc/fsl: Emulate SPRN_BUCSR register
  powerpc/fsl: Flush the branch predictor at each kernel entry (32 bit)
  powerpc/fsl: Sanitize the syscall table for NXP PowerPC 32 bit
    platforms
  powerpc/fsl: Fixed warning: orphan section `__btb_flush_fixup'
  powerpc/fsl: Add FSL_PPC_BOOK3E as supported arch for nospectre_v2
    boot arg
  Documentation: Add nospectre_v1 parameter

I applied the first 6 of these now.  If you could fix up the last two
and resend them, that would be wonderful.
