The kasan-enabled.h header relies on static keys, so make sure
to include the header to avoid compilation errors (with JUMP_LABEL=n).

It fixes the following:
./include/linux/kasan-enabled.h:9:1: warning: data definition has no type or storage class
    9 | DECLARE_STATIC_KEY_FALSE(kasan_flag_enabled);
      | ^~~~~~~~~~~~~~~~~~~~~~~~
error: type defaults to 'int' in declaration of 'DECLARE_STATIC_KEY_FALSE' [-Werror=implicit-int]

Fixes: f9b5e46f4097 ("kasan: split kasan_*enabled() functions into a separate header")

The patch looks fine but you should cc the kasan maintainers (just run
the patch through scripts/get_maintainer.pl). Adding Andrey as he acked
the patch being fixed here.

Thanks, Catalin.

Assuming linux/static_key.h is low-level enough to be included into
arch/arm64/include/asm/mte.h via linux/kasan-enabled.h,

Acked-by: Andrey Konovalov <andreyknvl@gmail.com>

for the fix.

Thank you!

Applied to arm64 (for-next/mte), thanks!

I accidentally deleted my sign off when adding the Fixes tag, spotted when merging into next:
  https://lore.kernel.org/lkml/20220309081719.54964469@canb.auug.org.au/

So here it is:
  Signed-off-by: Joey Gouly <joey.gouly@arm.com>

Let me know if I should resend the patch, or what I should do.

Thanks,
Joey

Thanks, I'll add that to the patch.
