[PATCH] uml: timer cleanups
set_interval returns an error instead of panicing if setitimer fails. Some of
its callers now check the return.
enable_timer is largely tt-mode-specific, so it is marked as such, and the
only skas-mode caller is made to call set-interval instead.
user_time_init was a no-value-added wrapper around set_interval, so it is
gone.
Since set_interval is now called from kernel code, callers no longer pass
ITIMER_* to it. Instead, they pass a flag which is converted into ITIMER_REAL
or ITIMER_VIRTUAL.
