tracing: Don't call page_to_pfn() if page is NULL

2014-02-10T21:11:07+00:00

commit 85f2a2ef1d0ab99523e0b947a2b723f5650ed6aa upstream.

When allocating memory fails, page is NULL. page_to_pfn() will
cause the kernel panicked if we don't use sparsemem vmemmap.

tracing: Fix timer tracing

2010-08-26T23:44:11+00:00

commit ede1b4290781ae82ccf0f2ecc6dada8d3dd35779 upstream.

PowerTOP would like to be able to trace timers.

Unfortunately, the current timer tracing is not very useful: the
actual timer function is not recorded in the trace at the start
of timer execution.

Although this is recorded for timer "start" time (when it gets
armed), this is not useful; most timers get started early, and a
tracer like PowerTOP will never see this event, but will only
see the actual running of the  timer.

This patch just adds the function to the timer tracing; I've
verified with PowerTOP that now it can get useful information
about timers.

tracing: Fix null pointer deref with SEND_SIG_FORCED

2010-07-05T18:22:52+00:00

commit b9b76dfaac6fa2c289ee8a005be637afd2da7e2f upstream.

BUG: unable to handle kernel NULL pointer dereference at
	0000000000000006
IP: [] ftrace_raw_event_signal_generate+0x87/0x140

TP_STORE_SIGINFO() forgets about SEND_SIG_FORCED, fix.

We should probably export is_si_special() and change TP_STORE_SIGINFO()
to use it in the longer term.
