Subject: [PATCH 2/7] x86/perf/amd: Fix build failure when CONFIG_HAVE_NMI_WATCHDOG is not set

From: "Lendacky, Thomas" <>

When CONFIG_HAVE_NMI_WATCHDOG is not set, the asm/nmi.h file is not
included. The asm/nmi.h file contains the definitions for NMI_HANDLED
and NMI_DONE which are used in arch/x86/events/amd/core.c. This causes
the build the fail.

Fix the issue by changing the include in arch/x86/events/amd/core.c from
linux/nmi.h to asm/nmi.h.
