msm: thermal: Update to speed up bootup time Update KTM driver to remove flush_scheduled_work that would introduce bootup delay. This patch replaces cancel_delayed_work with cancel_delayed_work_sync to cancel a delayed work.

pktgen: clean up ktime_t helpers

Some years ago, the ktime_t helper functions ktime_now() and ktime_lt()
have been introduced. Instead of defining them inside pktgen.c, they
should either use ktime_t library functions or, if not available, they
should be defined in ktime.h, so that also others can benefit from them.
ktime_compare() is introduced with a similar notion as in timespec_compare().

iopoll: Use ktime_get() instead of jiffies for timeout calculations Presently, small timeout values will round up to 1 jiffy which, on CONFIG_HZ=100 systems, corresponds to a full 10 milliseconds. This is undesirable for drivers specifying timeouts of only a few 10's of microseconds (which is common), since they may end up tight-loop spinning for hundreds or thousands of times longer than expected before reporting a timeout.

Additionally, jiffies cannot be reliably used with time_after()
when the value of jiffies is small (like 1). In rare but real
scenarios, jiffies may actually increment by more than 1 at a
time. Specifically, this will occur if interrupts are disabled
on for more than 1 jiffy (10 milliseconds for CONFIG_HZ=100) on
the CPU responsible for incrementing jiffies.

If interrupts are re-enabled on that CPU between the time the
iopoll code (on another CPU) calculates the timeout value of
jiffies and when the time_after() comparison is made, then the
iopoll APIs may return -ETIMEDOUT prematurely, even though the
specified timeout has not actually expired.

Using ktime_get() avoid this problem (which arguably also needs
a generic fix to avoid similar problems for other code which use
jiffies to calculate timeouts).
