The load/unload drm_driver ops are deprecated. They should be removed as
they result in creation of devices visible to userspace even before
the drm_device is registered.

Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref
to explicitly create and destroy the drm device in the msm platform
driver's bind and unbind ops. With this in use, the drm connectors are
only registered once the drm_device is registered.

It also fixes the issue of stray debugfs files after the msm module is
removed. With this, all the debugfs files are removed, and allows
successive module insertions/removals.

Pull power management and ACPI fixes from Rafael Wysocki:
 "Fixes for problems introduced or discovered recently (intel_pstate,
  sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
  generic device properties framework) and one fix for a hotplug-related
  deadlock in ACPICA that's been there forever, but is nasty enough.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver causing it
     to fail to restore the HWP (HW-managed P-states) configuration of
     the boot CPU after suspend-to-RAM (Rafael Wysocki).

   - Fix for two recent regressions in the intel_pstate driver, one that
     can trigger a divide by zero if the driver is accessed via sysfs
     before it manages to take the first sample and one causing it to
     fail to update a structure field used in a trace point, so the
     information coming from it is less useful (Rafael Wysocki).

   - Fix for a problem in the sti-cpufreq driver introduced during the
     4.5 cycle that causes it to break CPU PM in multi-platform kernels
     by registering cpufreq-dt (which subsequently doesn't work)
     unconditionally and preventing the driver that would actually work
     from registering (Sudeep Holla).

   - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
     usage counters to be incorrectly updated for idle states that were
     not entered due to errors (James Morse).

   - Fix for a recently introduced issue in the OPP (Operating
     Performance Points) framework causing it to print bogus error
     messages for missing optional regulators (Viresh Kumar).

   - Fix for a recently introduced issue in the generic device
     properties framework that may cause it to attempt to dereferece and
     invalid pointer in some cases (Heikki Krogerus).

   - Fix for a deadlock in the ACPICA core that may be triggered by
     device (eg Thunderbolt) hotplug (Prarit Bhargava)"

 - The new "error status translation" routine, introduced with the 4.6
   updates to the nfit driver, missed a necessary path in
   acpi_nfit_ctl().

byteswap: try to avoid __builtin_constant_p gcc bug

This is another attempt to avoid a regression in wwn_to_u64() after that
started using get_unaligned_be64(), which in turn ran into a bug on
gcc-4.9 through 6.1.

The regression got introduced due to the combination of two separate
workarounds (commits e3bde9568d99: "include/linux/unaligned: force
inlining of byteswap operations" and ef3fb2422ffe: "scsi: fc: use
get/put_unaligned64 for wwn access") that each try to sidestep distinct
problems with gcc behavior (code growth and increased stack usage).

Unfortunately after both have been applied, a more serious gcc bug has
been uncovered, leading to incorrect object code that discards part of a
function and causes undefined behavior.

As part of this problem is how __builtin_constant_p gets evaluated on an
argument passed by reference into an inline function, this avoids the
use of __builtin_constant_p() for all architectures that set
CONFIG_ARCH_USE_BUILTIN_BSWAP.  Most architectures do not set
ARCH_SUPPORTS_OPTIMIZED_INLINING, which means they probably do not
suffer from the problem in the qla2xxx driver, but they might still run
into it elsewhere.

Both of the original workarounds were only merged in the 4.6 kernel, and
the bug that is fixed by this patch should only appear if both are
there, so we probably don't need to backport the fix.  On the other
hand, it works by simplifying the code path and should not have any
negative effects.
