And by now, __init section codes should not been modified by ftrace, because it is black listed in recordmcount.c and ignored by ftrace.

| H A D | misc_64.S | diff 29430fae Sun Nov 03 19:32:53 MST 2019 Alastair D'Silva <alastair@d-silva.org> powerpc: Allow flush_icache_range to work across ranges >4GB When calling flush_icache_range with a size >4GB, we were masking off the upper 32 bits, so we would incorrectly flush a range smaller than intended. This patch replaces the 32 bit shifts with 64 bit ones, so that the full size is accounted for.
