Hi Al,
After merging the vfs tree, today's linux-next build (powercp
allyesconfig) failed like this (I have also included all the warnings):

Caused by commit
ba5214f7f40c ("vfs: Implement parameter value retrieval with fsinfo()")
which enabled CONFIG_SAMPLE_STATX. I have disabled that again. I assume
that problem is that these syscalls are not yet wired up on PowerPC ...
