Subject: ARM: convert to use __HEAD and HEAD_TEXT macros.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2abc1c50b6be81233e0b79478dc04d8fec737ed5;p=deliverable%2Flinux.git

ARM: convert to use __HEAD and HEAD_TEXT macros.

This has the consequence of changing the section name used for head
code from ".text.head" to ".head.text".  Since this commit changes all
users in the architecture, this change should be harmless.

The .text.head output section is eliminated and the head text code is
included at the start of the .init output section.
