This didn't seem to send properly, apologies if you get a duplicate.
Patch 1 is the important fix. 2 might fix something, although I haven't
provoked a crash yet.
Patch 3 is a small cleanup, and patch 4 I think is the right thing to do
but these could wait for later.
- Improved comments, changelogs, code style / wrapping.

powerpc/pseries: Fix hcall tracing recursion in pv queued spinlocks
powerpc/pseries: Don't trace hcall tracing wrapper
powerpc/pseries: use notrace hcall variant for H_CEDE idle
