On Alpha we have spinlocks that are 32b in size and an efficient
cmpxchg64 implementation, so we qualify to make use of cmpxchg backed
lockrefs. Select the ARCH_USE_CMPXCHG_LOCKREF Kconfig symbol and provide
a trivial implementation of arch_spin_value_unlocked to satisfy the
lockref code.

This patch creates a new script (compaction-times) to report time
spent in mm compaction. It is possible to report times in nanoseconds
(default) or microseconds (-u).
The option -p will break down results by process id, -pv will further
decompose by each compaction entry/exit.
For each compaction entry/exit what is reported is controlled by the
options:
-t report only timing
-m report migration stats
-ms report migration scanner stats
-fs report free scanner stats
The default is to report all.
Entries may be further filtered by pid, pid-range or comm (regex).
The script is useful when analysing workloads that compact memory. The
most common example will be THP allocations on systems with a lot of
uptime that has fragmented memory.
This is an example of using the script to analyse a thpscale from
mmtests which deliberately fragments memory and allocates THP in 4
separate threads

When calling regulator_set_load, regulator_check_drms prints and returns
an error if the regulator device's flag REGULATOR_CHANGE_DRMS isn't set.
drms_uA_update, however, bails out without reporting an error.
Replace the error print with a debug level print so that we don't get
such prints when the underlying regulator doesn't support DRMS.
