+Description: Fix detection of online CPUs in pa_ncpus()
+ PulseAudio uses sysconf(_NC_PROCESSORS_CONF) in pulsecore/
+ core-util.c:pa_ncpus() to determine the number of available
+ CPUs on the system.
+ .
+ However, since the operating system may disable individual CPUs,
+ the number of available CPUs may be smaller than _NC_PROCESSORS_CONF
+ and pa_ncpus() will therefore report an incorrect number of CPUs.
+ This makes the once-test fail on such systems like some of the
+ sparc64 buildds.
+ .
+ Patching pa_ncpus() to use _NC_PROCESSORS_CONF fixes this problem
+ and also results in once-test passing on the sparc64 buildds.
+ .
+ This has been reported upstream as:
+ https://bugs.freedesktop.org/show_bug.cgi?id=96809
+ .
