#     powerpc/kernel: Cleanup machine check function declarations
#     
#     __machine_check_early_realmode_p*() are currently declared as extern
#     in cputable.c and because of this when compiled with "C=1" (which
#     enables semantic checker) produces these warnings.
#     
#         CHECK   arch/powerpc/kernel/mce_power.c
#       arch/powerpc/kernel/mce_power.c:709:6: warning: symbol '__machine_check_early_realmode_p7' was not declared. Should it be static?
#       arch/powerpc/kernel/mce_power.c:717:6: warning: symbol '__machine_check_early_realmode_p8' was not declared. Should it be static?
#       arch/powerpc/kernel/mce_power.c:722:6: warning: symbol '__machine_check_early_realmode_p9' was not declared. Should it be static?
#       arch/powerpc/kernel/mce_power.c:740:6: warning: symbol '__machine_check_early_realmode_p10' was not declared. Should it be static?
#     
#     Patch here moves the declaration to asm/mce.h and includes the same in
#     cputable.c
#     
#     Fixes: ae744f3432d3 ("powerpc/book3s: Flush SLB/TLBs if we get SLB/TLB machine check errors on power8")
#     Fixes: 7b9f71f974a1 ("powerpc/64s: POWER9 machine check handler")
