Steven Rostedt (Google) 4ed308c445 ftrace: Have architectures opt-in for mcount build time sorting ... First S390 complained that the sorting of the mcount sections at build time caused the kernel to crash on their architecture. Now PowerPC is complaining about it too. And also ARM64 appears to be having issues. It may be necessary to also update the relocation table for the values in the mcount table. Not only do we have to sort the table, but also update the relocations that may be applied to the items in the table. If the system is not relocatable, then it is fine to sort, but if it is, some architectures may have issues (although x86 does not as it shifts all addresses the same). Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is safe to do the sorting at build time. Also update the config to compile in build time sorting in the sorttable code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.
