Currently, sba_process_deferred_requests() handles both pending
and completed sba_request which is unnecessary overhead for
sba_issue_pending() because completed sba_request handling is
not required in sba_issue_pending().

This patch breaks sba_process_deferred_requests() into two parts
sba_process_received_request() and _sba_process_pending_requests().

The sba_issue_pending() will only process pending sba_request
by calling _sba_process_pending_requests(). This will improve
sba_issue_pending().

The sba_receive_message() will only process received sba_request
by calling sba_process_received_request() for each received
sba_request. The sba_process_received_request() will also call
_sba_process_pending_requests() after handling received sba_request
because we might have pending sba_request not submitted by previous
call to sba_issue_pending().

When setting up RAID array on several NVMe disks we observed that
sba_alloc_request() start failing (due to no free requests left)
and RAID array setup becomes very slow.

To improve performance, we do mbox channel peek when we have
no free requests. This improves performance of RAID array setup
because mbox requests that were completed but not processed by
mbox completion worker will be processed immediately by mbox
channel peek.

The pending sba_request list can become very long in real-life usage
(e.g. setting up RAID array) which can cause sba_issue_pending() to
run for long duration.

This patch adds common sba_process_deferred_requests() to process
few completed and pending requests so that it finishes in short
duration. We use this common sba_process_deferred_requests() in
both sba_issue_pending() and sba_receive_message().

Currently, we have only 1024 free sba_request created
by sba_prealloc_channel_resources(). This is too low

at time of RAID array setup over NVMe disks.

This patch sets number of free sba_request created by
sba_prealloc_channel_resources() to be:

Currently, we cannot have any arbitrary number of free sba_request
because sba_prealloc_channel_resources() allocates an array of
sba_request using devm_kcalloc() and kcalloc() cannot provide
memory beyond certain size.

This patch removes "reqs" (sba_request array) from sba_device
and makes "cmds" as variable array (instead of pointer) in
sba_request. This helps sba_prealloc_channel_resources() to
allocate sba_request and associated SBA command in one allocation

  Mauro has gone through and fixed up a lot of top-level documentation

Unfortunately, on some models of some architectures getting a fully
seeded CRNG is extremely difficult, and so this can result in dmesg
getting spammed for a surprisingly long time.  This is really bad from
a security perspective, and so architecture maintainers really need to
do what they can to get the CRNG seeded sooner after the system is
booted.  However, users can't do anything actionble to address this,
and spamming the kernel messages log will only just annoy people.

For developers who want to work on improving this situation,
CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
CONFIG_WARN_ALL_UNSEEDED_RANDOM.  By default the kernel will always
print the first use of unseeded randomness.  This way, hopefully the
security obsessed will be happy that there is _some_ indication when
the kernel boots there may be a potential issue with that architecture
or subarchitecture.  To see all uses of unseeded randomness,
developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.

Pull power management fixes from Rafael Wysocki:
 "These fix a recently exposed issue in the PCI device wakeup code and
  one older problem related to PCI device wakeup that has been reported
  recently, modify one more piece of computations in intel_pstate to get
  rid of a rounding error, fix a possible race in the schedutil cpufreq
  governor, fix the device PM QoS sysfs interface to correctly handle
  invalid user input, fix return values of two probe routines in devfreq
  drivers and constify an attribute_group structure in devfreq.

  Specifics:

   - Avoid clearing the PCI PME Enable bit for devices as a result of
     config space restoration which confuses AML executed afterward and
     causes wakeup events to be lost on some systems (Rafael Wysocki).

   - Fix the native PCIe PME interrupts handling in the cases when the
     PME IRQ is set up as a system wakeup one so that runtime PM remote
     wakeup works as expected after system resume on systems where that
     happens (Rafael Wysocki).

   - Fix the device PM QoS sysfs interface to handle invalid user input
     correctly instead of using an unititialized variable value as the
     latency tolerance for the device at hand (Dan Carpenter).

   - Get rid of one more rounding error from intel_pstate computations
     (Srinivas Pandruvada).

   - Fix the schedutil cpufreq governor to prevent it from possibly
     accessing unititialized data structures from governor callbacks in
     some cases on systems when multiple CPUs share a single cpufreq
     policy object (Vikram Mulukutla).

   - Fix the return values of probe routines in two devfreq drivers
     (Gustavo Silva).

   - Constify an attribute_group structure in devfreq (Arvind Yadav)"

  lib/atomic64_test.c: add a test that atomic64_inc_not_zero() returns an int
  mm: fix overflow check in expand_upwards()

Using strscpy was wrong because FORTIFY_SOURCE is passing the maximum
possible size of the outermost object, but strscpy defines the count
parameter as the exact buffer size, so this could copy past the end of
the source.  This would still be wrong with the planned usage of
__builtin_object_size(p, 1) for intra-object overflow checks since it's
the maximum possible size of the specified object with no guarantee of
it being that large.

Reuse of the fortified functions like this currently makes the runtime
error reporting less precise but that can be improved later on.

  fixes/updates for Power9.
