Subject: [PATCH 0/4] x86/nmi: NMI cleanups

From: Lai Jiangshan <laijs@...ux.alibaba.com>

These are very simple cleanups for NMI.  They make NMI code a bit
tidier.

Patch1-3 are picked from the patchset
https://lore.kernel.org/lkml/20211126101209.8613-1-jiangshanlai@gmail.com/
which coverts ASM code to C code.

Patch4 is new.

Lai Jiangshan (4):
  x86/entry: Make paranoid_exit() callable
  x86/entry: Call paranoid_exit() in asm_exc_nmi()
  x86/nmi: Use DEFINE_IDTENTRY_NMI for NMI handler
  x86/nmi: Convert nmi_cr2/nmi_dr7 to be func-local variable
