Currently, kdump just makes all the logical processors leave VMX operation by
executing VMXOFF instruction, so any VMCSs active on the logical processors may
be corrupted. But, sometimes, we need the VMCSs to debug guest images contained
in the host vmcore. To prevent the corruption, we should VMCL

If the stop machinery is called from inactive CPU we cannot use
mutex_lock, because some other stomp machine invokation might be in

This patch changes the way to diplay the vector in trace_msi_set_irq from %x to
%u. Currently, it mismatches another output of ftrace such as kvm_msi_set_irq
and kvm_inj_virq which uses %u.

I took a look at this again. So not every hugetlb capable architecture
needs it, only architectures with multiple hugetlb page sizes.

Thanks for noticing the
With the addition of the "tsc" clock, formatting timestamps to look like
fractional seconds is misleading. Mark clocks as either in nanoseconds or
not, and format non-nanosecond timestamps as decimal integers.
Tested:
$ cd /sys/kernel/debug/tracing/
$ cat trace_clock

$ echo sche
In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously

Show raw time stamp values for stats per cpu if you choose counter or tsc mode
for trace_clock. Although a unit of tracing time stamp is nsec in local or
global mode,
the units in counter and TSC mode are tracing counter and cycles respectively.
