perf intel-pt: Fix syntax in documentation of config option
As specified in tools/perf/Documentation/perf-config.txt, perf configuration items must be in 'key = value' format, otherwise the following error message occurs: $ perf record -e intel_pt//u -- ls bad config file line 2 in ~/.perfconfig $ cat .perfconfig [intel-pt] mispred-all Changing to assigning a value to the key 'mispred-all' fixes the issue: $ perf record -e intel_pt//u -- ls [ perf record: Woken up 1 times to write data ] [ perf record: Capured and wrote 0.031 MB perf.data] $ cat .perfconfig [intel-pt] mispred-all = true Signed-off-by: Jack Henschel <jackdev@mailbox.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20170831080535.2157-1-jackdev@mailbox.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
