So this change triggered a build failure on 64-bit allmodconfig - fixed via the
patch below. Your change unearthed a latent bug, a missing header inclusion.
Thanks,

Subject: [PATCH] x86/platform/uv: Include clocksource.h for
clocksource_touch_watchdog()
This build failure triggers on 64-bit allmodconfig:
arch/x86/platform/uv/uv_nmi.c:493:2: error: implicit declaration of function
‘clocksource_touch_watchdog’ [-Werror=implicit-function-declaration]
which is caused by recent changes exposing a missing clocksource.h include
in uv_nmi.c:
cc1e24fdb064 x86/vdso: Remove pvclock fixmap machinery
this file got clocksource.h indirectly via fixmap.h - that stealth route
of header inclusion is now gone.
