Subject: linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

In file included from tools/arch/x86/include/asm/nops.h:5,
                 from arch/x86/decode.c:15:
tools/arch/x86/include/asm/asm.h:185:24: error: invalid register name for 'current_stack_pointer'
  185 | register unsigned long current_stack_pointer asm(_ASM_SP);
      |                        ^~~~~~~~~~~~~~~~~~~~~

Caused by commit

  eef23e72b78b ("x86/asm: Use _ASM_BYTES() in <asm/nops.h>")

I have used the tip tree from next-20210512 for today.
