Hi All,

This is a partial version of my 'ftrace syscalls, PowerPC: Various fixes,
Compat Syscall support and PowerPC implementation'. This is updated from
yesterday with arch_syscall_addr changed to a static inline function from
Steven's suggestion.

This subset implements the raw syscall tracepoints on PowerPC which has been
requested recently.  It also fixes ftrace syscalls to ensure that events will
only be created for syscalls that successfully map their metadata to a syscall
number, so that non-working phantom events are not created. Patches #2 and #6
in this series are not strictly necessary for this, they just optimise ftrace
syscalls a bit.

What's missing from this series that was in the full 40 patch v2 series is the
conversion of all the syscalls implemented under /arch/powerpc, Jason Baron's
compat syscall support and the conversion of the remaining native and compat
syscalls to this infrastructure.

Thanks Ian,

I'll pull this into my local repo and start running my tests on it.
