Subject: [PATCH v6 0/2] powerpc/32: Implement C syscall entry/exit (complement)

This series implements C syscall entry/exit for PPC32. It reuses
the work already done for PPC64.

This series is based on today's next-test (f538b53fd47a) where main patchs from v5 are merged in.

The first patch is important for performance.

v6:
- Forced scv param to 0 on syscall_exit_prepare(), and added is_not_scv bool.
- Reworked the last patch to avoid code duplication.

Christophe Leroy (2):
  powerpc/syscall: Do not check unsupported scv vector on PPC32
  powerpc/32: Handle bookE debugging in C in syscall entry/exit
