Hi all,

After merging the mm tree, today's linux-next build (i386 defconfig)
failed like this:

arch/x86/kernel/cpu/mce/severity.c: In function 'error_context':
arch/x86/kernel/cpu/mce/severity.c:305:22: error: implicit declaration of function 'FIELD_GET' [-Wimplicit-function-declaration]
  305 |         fixup_type = FIELD_GET(EX_DATA_TYPE_MASK, e->data);
      |                      ^~~~~~~~~

Caused by commit

  599382062e7b ("x86/mce: add EX_TYPE_EFAULT_REG as in-kernel recovery context to fix copy-from-user operations regression")

from the mm-unstable branch of the mm tree.

I have reverted that commit for today.
