+Subject: [PATCH] scripts/sorttable: Fix endianness handling in build-time
+ mcount sort
+
+Kernel cross-compilation with BUILDTIME_MCOUNT_SORT produces zeroed
+mcount values if the build-host endianness does not match the ELF
+file endianness.
+
+The mcount values array is converted from ELF file
+endianness to build-host endianness during initialization in
+fill_relocs()/fill_addrs(). Avoid extra conversion of these values during
+weak-function zeroing; otherwise, they do not match nm-parsed addresses
+and all mcount values are zeroed out.
+
+Fixes: ef378c3b8233 ("scripts/sorttable: Zero out weak functions in mcount_loc table")
