Masahiro Yamada 16f4e31951 include/linux/iopoll.h: include <linux/ktime.h> instead of <linux/hrtimer.h>
The timer APIs this header needs are ktime_get(), ktime_add_us(), and
ktime_compare().  So, including <linux/ktime.h> seems enough.  This
commit will cut unnecessary header file parsing.

Matt Wagantall 54c523127b iopoll: Introduce memory-mapped IO polling macros
It is sometimes necessary to poll a memory-mapped register until its value
satisfies some condition. Introduce a family of convenience macros that do
this. Tight-looping, sleeping, and timing out can all be accomplished using
these macros.
