The macro is related to sysfs, but is defined in kernel.h. Move it to
the proper header, and unload the generic kernel.h.

Tough guy :-)
I hope it builds well in your case.

FWIW,

Assuming it builds in allmodconfig, allyesconfig on x86_32/64 and arm/64
Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

I don't build allyesconfigs any more (final? linking takes too long).
It builds successfully for arm64 allmodconfig, arm allmodconfig,
i386 allmodconfig, and x86_64 allmodconfig.

And the source files that use VERIFY_OCTAL_PERMISSIONS() all build successfully
(which means that they possibly include <linux/sysfs.h> indirectly, i.e.,
by luck). There aren't many of them, so I checked:

arch/arc/kernel/perf_event.c:	arc_pmu->attr[j].attr.attr.mode = VERIFY_OCTAL_PERMISSIONS(0444);
INDIRECT
drivers/edac/thunderx_edac.c:	.mode = VERIFY_OCTAL_PERMISSIONS(_mode),		    \
INDIRECT
drivers/media/platform/amphion/vpu_dbg.c:		    VERIFY_OCTAL_PERMISSIONS(0644),
INDIRECT
drivers/soc/aspeed/aspeed-uart-routing.c:	 .mode = VERIFY_OCTAL_PERMISSIONS(0644) },	\
INDIRECT
fs/xfs/xfs_error.c:		 .mode = VERIFY_OCTAL_PERMISSIONS(S_IWUSR | S_IRUGO) },	\
INDIRECT
include/linux/moduleparam.h:	    VERIFY_OCTAL_PERMISSIONS(perm), level, flags, { arg } }
INDIRECT

so all of them got lucky. :)
