This patch adds reference counting to struct etr_buf so that, in CPU-wide
trace scenarios, shared buffers can be disposed of when no longer used.

There is no point in allocating sink memory for a trace session if
there is not a way to free it once it is no longer needed. As such make
sure the sink API function to allocate and free memory have been
implemented before moving ahead with the establishment of a trace
session.

In CPU-wide scenarios with an N:1 source/sink topology, sources share
the same sink. In order to reuse the same sink for all sources an
IDR is needed to archive events that have already been accounted for.

Refactoring function tmc_etr_setup_perf_buf() so that it only deals
with the high level etr_perf_buffer, leaving the allocation of the
backend buffer (i.e etr_buf) to another function.
That way the backend buffer allocation function can decide if it wants
to reuse an existing buffer (CPU-wide trac
In preparation to handle device reference counting inside of the sink
drivers, add a return code to the sink::disable() operation so that
proper action can be taken if a sink has not been disabled.

When disabling a sink the reference counter ensures the operation goes
through if nobody else is using it. As such if drvdata::mode is already
set do CS_MODE_DISABLED, it is an error and should be reported as such.

This is the third revision of a patchset that adds support for CPU-wide
trace scenarios and as such, it is now possible to issue the following
commands:
# perf record -e cs_etm/@2007.etr/ -C 2,3 $COMMAND
# perf record -e cs_etm/@2007.etr/ -a $COMMAND
The solution is design

In previous implementation, the number of refault pages is used
for judging the refault period of each page, which is not precised as
eviction of other files will be affect a lot on current cache.
We introduce the timestamp into the workingset's entry and refault ratio
