X-Git-Tag: v4.4.154~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed9c4055689cab0908fed0214dc0844babb83a6f;p=profile%2Fcommon%2Fplatform%2Fkernel%2Flinux-artik7.git

x86/irqflags: Mark native_restore_fl extern inline

commit 1f59a4581b5ecfe9b4f049a7a2cf904d8352842d upstream.

This should have been marked extern inline in order to pick up the out
of line definition in arch/x86/kernel/irqflags.S.

Fixes: 208cbb325589 ("x86/irqflags: Provide a declaration for native_save_fl")
