Subject: powerpc: define FUNC_START/FUNC_END
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=151f25112ff7befc134ed3fc58b0ff8792b3169e;p=linux-beck.git

powerpc: define FUNC_START/FUNC_END

gcc provides FUNC_START/FUNC_END macros to help with creating
assembly functions. Mirror these in the kernel so we can more easily
share code between userspace and the kernel. FUNC_END is just a
stub since we don't currently annotate the end of kernel functions.

It might make sense to do a wholesale search and replace, but for
now just create a couple of defines.
