Hi all,

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

arch/powerpc/lib/crc32-glue.c: In function 'crc32c_arch':
arch/powerpc/lib/crc32-glue.c:44:17: error: implicit declaration of function 'pagefault_disable'; did you mean 'preempt_disable'? [-Wimplicit-function-declaration]
   44 |                 pagefault_disable();
      |                 ^~~~~~~~~~~~~~~~~
      |                 preempt_disable
arch/powerpc/lib/crc32-glue.c:48:17: error: implicit declaration of function 'pagefault_enable'; did you mean 'preempt_enable'? [-Wimplicit-function-declaration]
   48 |                 pagefault_enable();
      |                 ^~~~~~~~~~~~~~~~
      |                 preempt_enable

   48 |                 pagefault_disable();
      |                 ^~~~~~~~~~~~~~~~~
      |                 preempt_disable
arch/powerpc/lib/crc-t10dif-glue.c:52:17: error: implicit declaration of function 'pagefault_enable'; did you mean 'preempt_enable'? [-Wimplicit-function-declaration]
   52 |                 pagefault_enable();
      |                 ^~~~~~~~~~~~~~~~
      |                 preempt_enable

Presumably caused by commit

  fcfbdddc6f02 ("crypto: ctr - Remove unnecessary header inclusions")

I have used the crypto tree from next-20250416 for today.
