Subject: [PATCH v2 1/3] powerpc: move the cpu_has_feature to a separate file
Date: Mon, 2 Sep 2013 13:45:24 +0800	[thread overview]
Message-ID: <1378100726-32545-2-git-send-email-haokexin@gmail.com> (raw)
In-Reply-To: <1378100726-32545-1-git-send-email-haokexin@gmail.com>

We plan to use jump label for cpu_has_feature. In order to implement
this we need to include the linux/jump_label.h in asm/cputable.h.
But it seems that asm/cputable.h is so basic header file for ppc that
it is almost included by all the other header files. The including of
the linux/jump_label.h will introduces various recursive inclusion.
And it is very hard to fix that. So we choose to move the function
cpu_has_feature to a separate header file before using the jump label
for it. No functional change.

v2: Update the commit log to replace the jump_label_base.h with jump_label.h.
