v2: Delete patch to remove SCRATCH 5 NMI support check for
UV2 and UV3k systems with old NMI support function.
v3: Fix check BIOS NMI support mistake in Patch 1.
Update NMI setup for UV5
Update NMI handler to interface with UV5 hardware. This involves
changing the EVENT_OCCURRED MMR used by the hardware and removes
the check for which NMI function is supported by UV BIOS. The
newer NMI function is assumed supported on UV5 and above.
Update TSC sync check for UV5
Update TSC to not check TSC sync state for uv5+ as it is not
available. It is assumed that TSC will always be in sync for
multiple chassis and will pass the tests for the kernel to
accept it as the clocksource. To disable this check use the
kernel start options tsc=reliable clocksource=tsc.
Log gap hole end size
Show value of gap end in the kernel log which equates to number
of physical address bits used by system. The end address of
the gap holds PA bits 56:26 which gives the range up to 64PB
max size with 64MB of granularity.
