[PATCH 00/11] Refactor exception entry on 40x/6xx/8xx

[Christophe Leroy]

This serie refactors exception entry macros for 40x, 6xx and 8xx

This serie will benefit to the implementation of CONFIG_VMAP, and also
to Ben's serie on MSR_EE.

First patch of this serie is a part of the CONFIG_THREAD_INFO_IN_TASK serie.
This avoids a conflict between the two series.

Christophe Leroy (11):
  powerpc/32: Rename THREAD_INFO to TASK_STACK
  powerpc/32: Refactor EXCEPTION entry macros for head_8xx.S and
    head_32.S
  powerpc/32: Add a macro for setting MSR_RI in EXCEPTION_PROLOG_2
  powerpc/32: add CLR_MSR_WE() in EXCEPTION_PROLOG in head_32.h
  powerpc/32: add START_EXCEPTION() in head_32.h
  powerpc/32: move LOAD_MSR_KERNEL() into head_32.h and use it
  powerpc/40x: Don't use SPRN_SPRG_SCRATCH2 in EXCEPTION_PROLOG
  powerpc/40x: add exception frame marker
  powerpc/40x: Split and rename NORMAL_EXCEPTION_PROLOG
  powerpc/40x: Add EXC_XFER_TEMPLATE_CRITICAL()
  powerpc/40x: Refactor exception entry macros by using head_32.h
