SubjectRe: [4.4 STABLE BACKPORT] x86: paravirt: make native_save_fl extern inline
Hi Nick,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/x86/core]
[cannot apply to v4.18-rc5 next-20180720]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Nick-Desaulniers/x86-paravirt-make-native_save_fl-extern-inline/20180721-073112
config: i386-tinyconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):

arch/x86/kernel/irqflags.S: Assembler messages:
>> arch/x86/kernel/irqflags.S:22: Error: bad register name `%_ASM_ARG1'

vim +22 arch/x86/kernel/irqflags.S
