Paul Mundt 9e5e21170e sh: Fix up the audit arch endian specification. 
Presently this was always being set to AUDIT_ARCH_SH, which assumes
big endian. Fix this up so that the architecture actually reflects
what we're running on.

Paul Mundt ab99c733ae sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME. 
This follows the changes in commits:

7d6d637dac
4f72c4279e

on powerpc. Adding in TIF_NOTIFY_RESUME, and cleaning up the syscall
tracing to be more generic. This is an incremental step to turning
on tracehook, as well as unifying more of the ptrace and signal code
across the 32/64 split.

Paul Mundt c459dbf294 sh: ptrace single stepping cleanups. 
This converts the single stepping done by sh/sh64 ptrace implementations
to use the generic user_enable/disable_single_step(), and subsequently
rips out a lot of ptrace request cases that are now handled generically.
