Subject: tools/objtool/Makefile: don't assume sync-check.sh is executable
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=50c1c6cc09dcea608ace4bd258714d01909fed45;p=android-x86%2Fkernel.git

tools/objtool/Makefile: don't assume sync-check.sh is executable

commit 0f908ccbeca99ddf0ad60afa710e72aded4a5ea7 upstream.

patch(1) loses the x bit.  So if a user follows our patching
instructions in Documentation/admin-guide/README.rst, their kernel will
not compile.

Fixes: 3bd51c5a371de ("objtool: Move kernel headers/code sync check to a script")
