#     Pull x86 irq entry updates from Thomas Gleixner:
#      "The irq stack switching was moved out of the ASM entry code in course
#       of the entry code consolidation. It ended up being suboptimal in
#       various ways.
#     
#       This reworks the X86 irq stack handling:
#     
#        - Make the stack switching inline so the stackpointer manipulation is
#          not longer at an easy to find place.
#     
#        - Get rid of the unnecessary indirect call.
#     
#        - Avoid the double stack switching in interrupt return and reuse the
#          interrupt stack for softirq handling.
#     
#        - A objtool fix for CONFIG_FRAME_POINTER=y builds where it got
#          confused about the stack pointer manipulation"
