Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from arch/powerpc/boot/stdio.c:12:0:
arch/powerpc/boot/stdio.h:10:17: error: expected declaration specifiers or =
'...' before numeric constant
arch/powerpc/boot/stdio.h:10:20: error: expected declaration specifiers or =
'...' before numeric constant
arch/powerpc/boot/stdio.h:10:8: warning: return type defaults to 'int'
arch/powerpc/boot/stdio.h:10:8: warning: function declaration isn't a proto=
type
arch/powerpc/boot/stdio.h: In function '__printf':
arch/powerpc/boot/stdio.h:14:17: error: expected declaration specifiers or =
'...' before numeric constant
arch/powerpc/boot/stdio.h:14:20: error: expected declaration specifiers or =
'...' before numeric constant
arch/powerpc/boot/stdio.h:14:23: error: expected '=3D', ',', ';', 'asm' or =
'__attribute__' before 'int'
arch/powerpc/boot/stdio.h:16:12: error: storage class specified for paramet=
er 'vsprintf'

And went down hill from there (it produced hundreds of errors).

Caused by commit a52af697aaeb ("treewide: use __printf not __attribute__
((format(printf,...)))").  Maybe because some of these files are part of
the boot wrappers and are built (effectively) independently of the kernel
itself.  Notice that arch/powerpc/boot/stdio.h does not include any
kernel headers ...

I have reverted that commit (and the follup ones b31d03e43e56
"treewide-use-__printf-not-__attribute__formatprintf-checkpatch-fixes"
and f43c361e2bd9 "kernel.h/checkpatch: mark strict_strto<foo> and
simple_strto<foo> as obsolete") for today.

Cheers,
