Minor /dev/hpet updates and bugfixes:
* Remove dead code, mostly remnants of an incomplete/unusable
kernel interface ... noted when addressing "sparse" warnings:
+ hpet_unregister() and a routine it calls
+ hpet_task and all references, including hpet_task_lock
+ hpet_data.hd_flags (and HPET_DATA_PLATFORM)* Correct and improve boot message:
+ displays *counter* (shared between comparators) bit width,
not *timer* bit widths (which are often mixed)
+ relabel "timers" as "comparators"; this is less confusing,
they are not independent like normal timers are (sigh)
+ display MHz not Hz; it's never less than 10 MHz.* Tighten and correct the userspace interface code
+ don't accidentally program comparators in 64-bit mode using
32-bit values ... always force comparators into 32-bit mode
+ provide the correct bit definition flagging comparators with
periodic capability ... the ABI is unchanged* Update Documentation/hpet.txt
+ be more correct and current
+ expand description a bit
+ don't mention that now-gone kernel interfacePlus, add a FIXME comment for something that could cause big trouble
on systems with more capable HPETs than at least Intel seems to ship.It seems that few folk use this userspace interface; it's not very
usable given the general lack of HPET IRQ routing. I'm told that
the only real point of it any more is to mmap for fast timestamps;
IMO that's handled better through the gettimeofday() vsyscall.Signed-off-by: David Brownell

We have two directories with timer related information in
Documentation/: hrtimers/ and hrtimer/. timer_stats are not restricted
to hrtimers. Move all those files into Documentation/timers where we
can pile up other timer related docs as well.Pointed-out-by: Randy Dunlap
