Hi Balbir,
[auto build test ERROR on powerpc/next]
[also build test ERROR on v4.12-rc2 next-20170525]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]
url:
https://github.com/0day-ci/linux/commits/Balbir-Singh/Enable-STRICT_KERNEL_RWX/20170525-150234
base: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: powerpc-allmodconfig (attached as .config)
compiler: powerpc64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
wget
https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O
~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=powerpc
All errors (new ones prefixed by >>):
kernel//power/snapshot.c:40:28: fatal error: asm/set_memory.h: No such file or
directory
#include <asm/set_memory.h>
Looks like it is linked to commit 50327ddfb ("kernel/power/snapshot.c:
use set_memory.h header").
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=50327ddfb
I believe that inclusion should be conditional to
CONFIG_ARCH_HAS_SET_MEMORY, which is not set by powerpc arch, just like
in include/linux/filter.c
