From: Li Zhong <zh...@linux.vnet.ibm.com>
Saw the following compiler warning on next tree:
kernel/itimer.c: In function 'set_cpu_itimer':
kernel/itimer.c:152:2: warning: passing argument 1 of
'timeval_to_cputime' discards 'const' qualifier from pointer target type
[enabled by default]
...
timeval_to_cputime() is always passed a constant timeval in
argument, we need to teach the nsecs based cputime implementation
about that.
