[PATCH 0/8] perf tools: Various updates

[Robert Richter <robert.richter@amd.com>]

This patch set contains various perf tools updates. Most patches deal
with event naming. If the event name is unknown it is named like the
command line string of it. This is esp. valueable for pmu events like
for AMD IBS:

     $ perf report | grep '^#.*event'
     # event : name = ibs_op/cnt_ctl=1/GH, type = 7, config = 0x80000, config1 = 0x0, config2 = 0x0, excl_usr = 0, excl_kern = 0, excl_host = 0, excl_guest = 0, precise_ip = 0, id = { 
     # event : name = ibs_fetch/config=0/, type = 6, config = 0x0, config1 = 0x0, config2 = 0x0, excl_usr = 0, excl_kern = 0, excl_host = 0, excl_guest = 1, precise_ip = 0, id = { 57, 
     # Samples: 20K of event 'ibs_op/cnt_ctl=1/GH'
     # Samples: 4K of event 'ibs_fetch/config=0/'

Another patch stores the pmu/type mapping in the header of perf.data.
Now the pmu types are known and event can be attributed to a certain
dynamically allocated pmu:

     # pmu mappings: ibs_op = 7, ibs_fetch = 6, cpu = 4, breakpoint = 5, tracepoint = 2, software = 1

This is usefull for analysing the perf.data file on a system where the
pmu mappings are no longer available, e.g. on a remote system or if
the pmu has been unregistered.

Patches base on commit 0c21f736e0a37c50f66ab248d2a52f711b28a4e4
