Two fixes for the scheduler:
- Work around an uninitializaed variable warning where GCC can't figure it
out.
- Allow 'isolcpus=' to skip unknown subparameters so that older kernels
work with the commandline of a newer kernel. Improve the error output
while at it.
sched/vtime: Work around an unitialized variable warning
Work around this warning:
kernel/sched/cputime.c: In function ‘kcpustat_field’:
kernel/sched/cputime.c:1007:6: warning: ‘val’ may be used uninitialized in this function [-Wmaybe-uninitialized]
because GCC can't see that val is used only when err is 0.
