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.

iopoll: Introduce memory-mapped IO polling macros2015-01-19T16:11:59ZMatt Wagantallmattw@codeaurora.org2014-12-15T23:47:23Zurn:sha1:54c523127bcca986c6f9b04c7b56a949ea011899
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.
