When ARM 64 is compiled with gcc, the mcount_loc section will be filled
with zeros and the addresses will be located in the Elf_Rela sections. To
sort the mcount_loc section, the addresses from the Elf_Rela need to be
placed into an array and that is sorted.
But when ARM 64 is compiled with clang, it ... | ```diff

As kaslr_offset() is architecture dependent and also may not be defined by
all architectures, when zeroing out unused weak functions, do not check
against kaslr_offset(), but instead check if the address is within the
kernel text sections. If KASLR added a shift to the zeroed out function,
