When vendor hooks are added to a file that previously didn't have any
vendor hooks, we end up indirectly including linux/tracepoint.h. This
causes some data types that used to be opaque (forward declared) to the
code to become visible to the code.
Modversions correctly catches this change in visibility, but we don't
really care about the data types made visible when linux/tracepoint.h is
included. So, hide this from modversions in the central vendor_hooks.h file
instead of having to fix this on a case by case basis.
This change itself will cause a one time CRC breakage/churn because it's
fixing the existing vendor hook headers, but should reduce unnecessary CRC
churns in the future.
To avoid future pointless CRC churn, vendor hook header files that include
vendor_hooks.h should not include linux/tracepoint.h directly.

When a kernel panic occurred, it is sometimes caused by a other cpu
than the panic cpu. When a panic cpu sends smp stop IPI, it can help to
solve the problem even more if aonther cpu stores registers and
run cache flush.
