[PATCH 0/6] perf trace: Add filter support

This patchset adds filter support for perf counter, so not all
profile events are recorded but only those match the filters
we set.

An example:

#./perf record -f -e irq:irq_handler_entry:irq==18:record
or
#./perf record -f -e irq:irq_handler_entry:irq==18 -R
^C
# ./perf trace
version = 0.5
perf-4303 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
