[0/6] perf intel-pt: Add support for tracing KVM test programs

Message

Hi

A common case for KVM test programs is that the guest object code can be
found in the hypervisor process (i.e. the test program running on the
host).  Add support for that.

For some more details refer the 3rd patch "perf tools: Add guest_code
support"

For an example, see the last patch "perf intel-pt: Add guest_code support"

For more information about Perf tools support for Intel® Processor Trace
refer:
