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.
