#     Merge tag 'powerpc-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#      "It's a bit of a big batch for rc6, but just because I didn't send any
#       fixes the last week or two while I was on vacation, next week should
#       be quieter:
#     
#        - Fix a few objtool warnings since we recently enabled objtool.
#     
#        - Fix a deadlock with the hash MMU vs perf record.
#     
#        - Fix perf profiling of asynchronous interrupt handlers.
#     
#        - Revert the IMC PMU nest_init_lock to being a mutex.
#     
#        - Two commits fixing problems with the kexec_file FDT size
#          estimation.
#     
#        - Two commits fixing problems with strict RWX vs kernels running at
#          non-zero.
#     
#        - Reconnect tlb_flush() to hash__tlb_flush()
#     
#       Thanks to Kajol Jain, Nicholas Piggin, Sachin Sant Sathvika Vasireddy,
#       and Sourabh Jain"
