c139aa60c1 arm64: barriers: fix smp_load_acquire to work with const arguments
A newly introduced function in include/net/sock.h passes a const
argument to smp_load_acquire:

  static inline int sk_state_load(const struct sock *sk)
  {
	return smp_load_acquire(&sk->sk_state);
  }

This cause an allmodconfig build failure, since our underlying
load-acquire implementation does not handle const types correctly:

  include/net/sock.h: In function 'sk_state_load':
  ./arch/arm64/include/asm/barrier.h:71:3: error: read-only variable '___p1' used as 'asm' output
     asm volatile ("ldarb %w0, %1"    \

This patch fixes the problem by reusing the trick in READ_ONCE that
loads via a non-const member of an anonymous union. This has the
advantage of allowing us to use smp_load_acquire on packed structures
(e.g. arch_spinlock_t) as well as primitive types.

dad67d5f3d xhci: Fix a race in usb2 LPM resume, blocking U3 for usb2 devices
Clear device initiated resume variables once device is fully up and running
in U0 state.

Resume needs to be signaled for 20ms for usb2 devices before they can be
moved to U0 state.

An interrupt is triggered if a device initiates resume. As we handle the
event in interrupt context we can not sleep for 20ms, so we instead set
a resume flag, a timestamp, and start the roothub polling.

The roothub code will later move the port to U0 when it finds a port in
resume state with the resume flag set, and timestamp passed by 20ms.

A host initiated resume is however not done in interrupt context, and
host initiated resume code will directly signal resume, wait 20ms and then
move the port to U0.

These two codepaths can race, if we are in the middle of a host initated
resume, while sleeping for 20ms, we may handle a port event and find the
port in resume state. The port event handling code will assume the resume
was device initiated and set the resume flag and timestamp.

Root hub code will however not catch the port in resume state again as the
host initated resume code has already moved the port to U0.
The resume flag and timestamp will remain set for this port preventing port
from suspending again  (LPM setting port to U3)

Fix this for now by always clearing the device initated resume parameters
once port is in U0

42df7215fa usb: xhci: fix checking ep busy for CFC
Function ep_ring_is_processing() checks the dequeue pointer
in endpoint context to know whether an endpoint is busy with
processing TRBs. This is not correct since dequeue pointer
field in an endpoint context is only valid when the endpoint
is in Halted or Stopped states. This buggy code causes audio
noise when playing sound with USB headset connected to host
controllers which support CFC (one of xhci 1.1 features).

This patch should exist in stable kernel since v4.3.

a596439619 xhci: Workaround to get Intel xHCI reset working more reliably
Existing Intel xHCI controllers require a delay of 1 mS,
after setting the CMD_RESET bit in command register, before
accessing any HC registers. This allows the HC to complete
the reset operation and be ready for HC register access.
Without this delay, the subsequent HC register access,
may result in a system hang, very rarely.

Verified CherryView / Braswell platforms go through over
5000 warm reboot cycles (which was not possible without
this patch), without any xHCI reset hang.

00490c22b1 drm/i915: Consider SPLL as another shared pll, v2.
When diagnosing a unrelated bug for someone on irc, it would seem the hardware can
be brought up by the BIOS with the embedded displayport using the SPLL for spread spectrum.

Right now this is not handled well in i915, and it calculates the crtc needs to
be reprogrammed on the first modeset without SSC, but  the SPLL itself was kept
active. Fix this by exposing SPLL as a shared pll that will not be returned
by intel_get_shared_dpll; you have to know it exists to use it.

Changes since v1:
- Create a separate dpll_hw_state.spll for spll, and use
  separate pll functions for spll.

From Ard:

"PAGE_KERNEL_EXEC has PTE_WRITE set as well, making the range
writeable under the ARMv8.1 DBM feature, that manages the
dirty bit in hardware (writing to a page with the PTE_RDONLY
and PTE_WRITE bits both set will clear the PTE_RDONLY bit in that case)"

08c6781cfa arm64: crypto: reduce priority of core AES cipher
The asynchronous, merged implementations of AES in CBC, CTR and XTS
modes are preferred when available (i.e., when instantiating ablkciphers
explicitly). However, the synchronous core AES cipher combined with the
generic CBC mode implementation will produce a 'cbc(aes)' blkcipher that
is callable asynchronously as well. To prevent this implementation from
being used when the accelerated asynchronous implemenation is also
available, lower its priority to 250 (i.e., below the asynchronous
module's priority of 300).

65da0a8e34 arm64: use non-global mappings for UEFI runtime regions
As pointed out by Russell King in response to the proposed ARM version
of this code, the sequence to switch between the UEFI runtime mapping
and current's actual userland mapping (and vice versa) is potentially
unsafe, since it leaves a time window between the switch to the new
page tables and the TLB flush where speculative accesses may hit on
stale global TLB entries.

So instead, use non-global mappings, and perform the switch via the
ordinary ASID-aware context switch routines.

Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

  - Do not change the key of an object in a rbtree, this time it was
    the one for DSOs lookup by its long_name, and the noticed symptom was
    with 'perf buildid-list --with-hits' (Adrian Hunter)

  - 'perf inject' is a pipe, events it doesn't touch should be passed
    on, PERF_RECORD_LOST wasn't, fix it (Adrian Hunter)

  - Make 'perf buildid-list' request event ordering, as it needs to
    first get the mmap events to be able to mark wich DSOs had hits
    (Adrian Hunter)

  - Fix memory leaks on failure in 'perf probe' (Masami Hiramatsu, Wang Nan)

1ef0623371 kernel-doc: Make it compatible with Perl versions below 5.12 again
Changeset 4d73270192ec('scripts/kernel-doc: Replacing highlights
hash by an array') broke compatibility of the kernel-doc script with
older versions of perl by using "keys ARRAY" syntax with is available
only on Perl 5.12 or newer, according with:
	http://perldoc.perl.org/functions/keys.html

Restore backward compatibility by replacing "foreach my $k (keys ARRAY)"
by a C-like variant: "for (my $k = 0; $k < !ARRAY; $k++)"

aa05cfa95f usb: fixes for v4.4-rc2
First round of fixes for this -rc cycle. We have the
 usual set of miscellaneous fixes. The important
 thing here is support for Intel Broxton SoC on dwc3,
 some fixes for Rockchip SoCs on dwc2 and a fix on
 dwc3 to let it report lower speeds than
 USB_SPEED_SUPER.
