59d805af41 Input: hil_mlc - convert timeval to jiffies
struct timeval is not y2038 safe, and what mlc->instart do is
scheduling a task in a fixed timeout, so jiffies is the
simplest choice here.

In hilse_donode(), the expires in mod_timer equals

	jiffies + intimeout - (now - instart)

If we use jiffies in 'now', the expires equals

	instart + intimeout

So, all we need to do is that making sure expires is a future
timestamp before passed it to mod_timer.

[arnd: slightly simplified patch further]

ac45e6293f Input: hil_mlc - convert timeval to time64_t
Since mlc->lcv_t is only interested in seconds, directly using time64_t
here.

This gets rid of the deprecated do_gettimeofday() and avoids problems
with time going backwards since we now use the monotonic clocksource.

Reorder code in gscps2_interrupt() and only enable ports when opened.
This fixes issues with hangs booting an SMP kernel on my C360.
Previously serio_interrupt() could be called before the lock in
struct serio was initialised.
