Once again, we see

when compiling ppc:allmodconfig.

This time the problem has been caused by to commit 0869b6fd209bda
("powerpc/book3s: Add basic infrastructure to handle HMI in Linux"),
which adds functions hmi_exception_early and hmi_exception_after_realmode
into a critical (size-limited) code area, even though that does not appear
to be necessary.

Move those functions to a non-critical area of the file.

Compile tested with all ppc configurations.
The reported checkpatch error appears to be a false positive.


I have added that to my fixes tree for today.
