Hi all,

My qemu boot test (pseries_le_defconfig) produces these new messages:

Maybe caused by commit

  8b8a8f0ab3f5 ("powerpc/code-patching: Improve verification of patchability")

As an presumably unrelated aside, we seem to be using a bit more stack
space as well

- mount (54) used greatest stack depth: 12512 bytes left
- mount (55) used greatest stack depth: 12032 bytes left
+ mount (54) used greatest stack depth: 10608 bytes left
