#     powerpc/irq: Inline call_do_irq() and call_do_softirq()
#     
#     call_do_irq() and call_do_softirq() are simple enough to be
#     worth inlining.
#     
#     Inlining them avoids an mflr/mtlr pair plus a save/reload on stack. It
#     also allows GCC to keep the saved ksp_limit in an nonvolatile reg.
#     
#     This is inspired from S390 arch. Several other arches do more or
#     less the same. The way sparc arch does seems odd thought.

#     v2: no change.
#     v3: no change.
#     v4:
#     - comment reminding the purpose of the inline asm block.
#     - added r2 as clobbered reg
#     v5:
#     - Limiting the change to PPC32 for now.
#     - removed r2 from the clobbered regs list (on PPC32 r2 points to current all the time)
#     - Removed patch 1 and merged ksp_limit handling in here.
#     v6:
#     - Rebase on top of merge-test (ca6e327fefb2).
#     - Remove the ksp_limit stuff as it's doesn't exist anymore.
#     
#     v7:
#     mpe:
#     - Enable for 64-bit too. This all in-kernel code calling in-kernel
#       code, and must use the kernel TOC.
#     - Use named parameters for the inline asm.
#     - Reformat inline asm.
#     - Mark as always_inline.
#     - Drop unused ret from call_do_softirq(), add r3 as clobbered.
