#     
#     Pull ARM updates from Russell King:
#      "Updates for IRQ stacks and virtually mapped stack support, and ftrace:
#     
#        - Support for IRQ and vmap'ed stacks
#     
#          This covers all the work related to implementing IRQ stacks and
#          vmap'ed stacks for all 32-bit ARM systems that are currently
#          supported by the Linux kernel, including RiscPC and Footbridge. It
#          has been submitted for review in four different waves:
#     
#           - IRQ stacks support for v7 SMP systems [0]
#     
#           - vmap'ed stacks support for v7 SMP systems[1]
#     
#           - extending support for both IRQ stacks and vmap'ed stacks for all
#             remaining configurations, including v6/v7 SMP multiplatform
#             kernels and uniprocessor configurations including v7-M [2]
#     
#           - fixes and updates in [3]
#     
#        - ftrace fixes and cleanups
#     
#          Make all flavors of ftrace available on all builds, regardless of
#          ISA choice, unwinder choice or compiler [4]:
#     
#           - use ADD not POP where possible
#     
#           - fix a couple of Thumb2 related issues
#     
#           - enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness
#     
#           - enable the graph tracer with the EABI unwinder
#     
#           - avoid clobbering frame pointer registers to make Clang happy
#     
#        - Fixes for the above"
