posix-cpu-timers: fix clock_gettime with CLOCK_PROCESS_CPUTIME_ID
Petr Tesarik [Mon, 24 Nov 2008 14:46:31 +0000 (15:46 +0100)]
Since CLOCK_PROCESS_CPUTIME_ID is in fact translated to -6, the switch
statement in cpu_clock_sample_group() must first mask off the irrelevant
bits, similar to cpu_clock_sample().
