Subject: mm: use macros from compiler.h instead of __attribute__((...))
X-Git-Tag: v3.15-rc1~57^2~129
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b32123d734cb414e366b35a3b2142a995f9d1a0;p=pandora-kernel.git

mm: use macros from compiler.h instead of __attribute__((...))

To increase compiler portability there is <linux/compiler.h> which
provides convenience macros for various gcc constructs.  Eg: __weak for
__attribute__((weak)).  I've replaced all instances of gcc attributes with
the right macro in the memory management (/mm) subsystem.
