[ 29/34] xtensa: fix linker script transformation for .text.unlikely

From: Greg Kroah-Hartman
Date: Sun Aug 18 2013 - 16:50:08 EST


3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Max Filippov <jcmvbkbc@xxxxxxxxx>

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.
