Hi Andrew,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
In file included from arch/powerpc/kernel/asm-offsets.c:16:0:
include/linux/signal.h: In function 'sigisemptyset':
include/linux/signal.h:79:3: error: implicit declaration of function 'BUILD_BUG' [-Werror=implicit-function-declaration]
BUILD_BUG();
^
Caused by commit 7e52cdba7e69 ("signal: use BUILD_BUG() instead of
_NSIG_WORDS_is_unsupported_size()").
See Rule 1 in Documentation/SubmitChecklist.
Thanks to Guenter for the heads up.
I have added the following patch for today (hopefully it does not cause
more problems).
