Subject: [patch 1/2] kcmp: Make it to depend on CONFIG_KCMP
Date: Tue, 19 Feb 2013 10:48:01 +0400 [thread overview]

[-- Attachment #1: kcmp-config --]
[-- Type: text/plain, Size: 2322 bytes --]
Since kcmp syscall has been implemented (initially on
x86 architecture) a number of other archs wire it up
as well: xtensa, sparc, sh, s390, mips, microblaze,
m68k (not taking into account those who uses
<asm-generic/unistd.h> for syscall numbers
definitions).
But the Makefile, which turns kcmp.o generation on
still depends on former config-x86. Thus get rid
of this limitation and make kcmp.o depend on CONFIG_KCMP
option.
