nanosleep: Use get_timespec64() and put_timespec64()

2017-06-30T08:14:14+00:00

Usage of these apis and their compat versions makes
the syscalls: clock_nanosleep and nanosleep and
their compat implementations simpler.

This is a preparatory patch to isolate data conversions to
struct timespec64 at userspace boundaries. This helps contain
the changes needed to transition to new y2038 safe types.

posix-timers: Make nanosleep timespec argument const

2017-06-13T22:00:47+00:00

No nanosleep implementation modifies the rqtp argument. Mark is const.

time/posix-timers: Move the compat copyouts to the nanosleep implementations

2017-06-13T22:00:42+00:00

Turn restart_block.nanosleep.{rmtp,compat_rmtp} into a tagged union (kind =
1 -> native, kind = 2 -> compat, kind = 0 -> nothing) and make the places
doing actual copyout handle compat as well as native (that will become a
helper in the next commit).  Result: compat wrappers, messing with
reassignments, etc. are gone.

hrtimer: Move copyout of remaining time to do_nanosleep()

2017-06-13T22:00:41+00:00

The hrtimer nanosleep() implementation can be simplified by moving the copy
out of the remaining time to do_nanosleep() which is shared between the
real nanosleep function and the restart function.

The pointer to the timespec64 which is updated is already stored in the
restart block at the call site, so the seperate handling of nanosleep and
restart function can be avoided.

hrtimer_nanosleep(): Pass rmtp in restart_block

2017-06-13T22:00:40+00:00

Store the pointer to the timespec which gets updated with the remaining
time in the restart block and remove the function argument.

time: Change k_clock nsleep() to use timespec64

2017-04-14T19:49:56+00:00

struct timespec is not y2038 safe on 32 bit machines.  Replace uses of
struct timespec with struct timespec64 in the kernel.

The syscall interfaces themselves will be changed in a separate series.

Note that the restart_block parameter for nanosleep has also been left
unchanged and will be part of syscall series noted above.

This patch fix spelling typos found in
Documentation/output/xml/driver-api/basics.xml.
It is because the xml file was generated from comments in source,
so I had to fix the comments.
