3.5.7.21 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Max Filippov <jcmvbkbc@gmail.com>
commit f6a03a12ecdbe0dd80a55f6df3b7206c5a403a49 upstream.
Now that binutils generate *.unlikely sections which don't follow documented (info as) literal section naming rules, section name transformation script doesn't work well resulting in the following errors at vmlinux link time:
main.c:(.text.unlikely+0x3): dangerous relocation: l32r: literal placed after use: .literal.unlikely
Fix section name transformation script by adding specific rule for .text.unlikely sections.
