Ok, could you try by replacing #ifdef CONFIG_STRICT_KERNEL_RWX by #if 0
in arch/powerpc/lib/code-patching.c


With this change and CONFIG_STRICT_KERNEL_RWX=y, it still boots.

BTW, I get these warnings (sorry for the word wrap from screen paste) -
may they be related or rather not?

  WRAP    arch/powerpc/boot/zImage.pmac
  WRAP    arch/powerpc/boot/zImage.coff
  WRAP    arch/powerpc/boot/zImage.miboot

INFO: Uncompressed kernel (size 0x5d4c3c) overlaps the address ofthe wrapper(0x400000)

INFO: Fixing the link_address of wrapper to (0x600000)

Then i believe there is something wrong with commithttps://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20171115&id=37bc3e5fd764fb258ff4fcbb90b6d1b67fb466c1


Balbir, do you have any idea ?
