[PATCH 00/10] Move 64e to new interrupt return code

[Nicholas Piggin]

Since RFC this is rebased on Christophe's v3 ppc32 conversion, and
has fixed up small details, and then adds some powerpc-wide
cleanups at the end.

Tested on qemu only (QEMU e500), which is not ideal for interrupt
handling particularly the critical interrupts which I don't know
whether it can generate.

Thanks,
Nick

Nicholas Piggin (10):
  powerpc/syscall: switch user_exit_irqoff and trace_hardirqs_off order
  powerpc/64e/interrupt: always save nvgprs on interrupt
  powerpc/64e/interrupt: use new interrupt return
  powerpc/64e/interrupt: NMI save irq soft-mask state in C
  powerpc/64e/interrupt: reconcile irq soft-mask state in C
  powerpc/64e/interrupt: Use new interrupt context tracking scheme
  powerpc/64e/interrupt: handle bad_page_fault in C
  powerpc: clean up do_page_fault
  powerpc: remove partial register save logic
  powerpc: move norestart trap flag to bit 0
