Subject: [PATCH v2] kernel: use the gnu89 standard explicitly
Date: Sun, 19 Oct 2014 22:40:55 -0400 [thread overview]
Message-ID: <1413772855-8613-1-git-send-email-sasha.levin@oracle.com> (raw)
gcc5 changes the default standard to c11, which makes kernel
build unhappy.
Explicitly define the kernel standard to be gnu89 which should
keep everything working exactly like it was before gcc5.
Signed-off-by: Sasha Levin <sasha.levin@oracle.com>

Changes from v1:
- I've accidently placed the statement in a CONFIG_READABLE_ASM.
It shouldn't be there.
