Hello:

This series was applied to riscv/linux.git (fixes)

RISC-V uses -fpatchable-function-entry=8,4 when the compressed ISA is
enabled and -fpatchable-function-entry=4,2 otherwise. In both cases, the
patchable NOP area starts 8 bytes before the function symbol address.
The __mcount_loc entries therefore point at the patchable NOP area
associated with a function, while nm reports the function symbol at the
entry address used for the function range check.
