A variety of (mostly) innocuous fixes to the embedded kernel-doc content in
source files, including:
* make multi-line initial descriptions single line
* denote some function names, constants and structs as such
* change erroneous opening '/*' to '/**' in a few places
* reword some text for clarity

The 32 bit implementation of ktime_to_ns returns unsigned value, while the
64 bit version correctly returns an signed value. There is no current user
affected by this, but it has to be fixed, as ktime values can be negative.

Frank v. Waveren pointed out that on 64bit machines the timespec to
ktime_t conversion might overflow. This is also true for timeval to
ktime_t conversions. This breaks a "sleep inf" on 64bit machines.
While a timespec/timeval with tx.sec = MAX_LONG is valid by specification
the internal representation of ktime_t is based on nanoseconds. The
conversion of seconds to nanoseconds overflows for seconds values >=
(MAX_LONG / NSEC_PER_SEC).
Check the seconds argument to the conversion and limit it to the maximum
time which can be represented by ktime_t.

Now that it_real_value is gone, the last user of DEFINE_KTIME and
ktime_to_clock_t are also gone, so remove it before someone starts using it
again.

For two macros the arguments were expanded twice, change them to inline
functions to avoid it.

At some point we added credits to people who actively helped to bring
k/hr-timers along. This was lost in the big code revamp. Add it back.

Change the storage format of the per base resolution to ktime_t to
make it easier accessible in the hrtimers code.
Change the resolution from (NSEC_PER_SEC/HZ) to TICK_NSEC as Roman
pointed out. TICK_NSEC is closer to the real resolution.

hrtimer subsystem core. It is initialized at bootup and expired by the timer
interrupt, but is otherwise not utilized by any other subsystem yet.

- introduce ktime_t: nanosecond-resolution time format.
- eliminate the plain s64 scalar type, and always use the union.
This simplifies the arithmetics. Idea from Roman Zippel.
