RE: [PATCH 1/3] kbuild: complain about missing system calls.

["Luck, Tony" <tony.luck@intel.com>]

Looks more complex than necessary.  Why do you want to execute
an arch specific script to list the __IGNORE symbols?  That would
allow an arch to generate a list with sed/perl/etc. but that
looks like overkill.

If you just have an arch specific file with the right defines.
E.g. for x86_64 in include/asm-x86_64/ignore_syscalls:

#include __IGNORE_getcpu

Then the checksyscalls.sh changes would just be something like
(do I need a ${srctree} before the include??):

diff --git a/scripts/checksyscalls.sh b/scripts/checksyscalls.sh
index f98171f..616f7c5 100755
