When removing a device with less than 9 IRQs (AMBA_NR_IRQS), we'll get a
big WARN_ON from devres.c because pl330_remove calls devm_free_irqs for
unallocated irqs. Similarly to pl330_probe, check that IRQ number is
present before calling devm_free_irq.

There are three timing problems in the kthread usages of iscsi_target_mod:
- np_thread of struct iscsi_np
- rx_thread and tx_thread of struct iscsi_conn
In iscsit_close_connection(), it calls
send_sig(SIGINT, conn->tx_thread, 1);
kthread_stop(conn->tx_thread);
In conn->tx_thread, which is iscsi_target_tx_thread(), when it receive
SIGINT the kthread will exit without checking the return value of
kthread_should_stop().
So if iscsi_target_tx_thread() exit right between send_sig(SIGINT...)
and kthread_stop(...), the kthread_stop() will try to stop an already
stopped kthread.
This is invalid according to the documentation of kthread_stop().

This patch fixes a OOPs originally introduced by:
commit bb048357dad6d604520c91586334c9c230366a14
Author: Nicholas Bellinger <nab@linux-iscsi.org>
Date: Thu Sep 5 14:54:04 2013 -0700
iscsi-target: Add sk->sk_state_change to cleanup after TCP failure
which would trigger a NULL pointer dereference when a TCP connection
was closed asynchronously via iscsi_target_sk_state_change(), but only
when the initial PDU processing in iscsi_target_do_login() from iscsi_np
process context was blocked waiting for backend I/O to complete.
To address this issue, this patch makes the following changes.
First, it introduces some common helper functions used for checking
socket closing state, checking login_flags, and atomically checking
socket closing state + setting login_flags.
Second, it introduces a LOGIN_FLAGS_INITIAL_PDU bit to know when a TCP
connection has dropped via iscsi_target_sk_state_change(), but the
initial PDU processing within iscsi_target_do_login() in iscsi_np
context is still running. For this case, it sets LOGIN_FLAGS_CLOSED,
but doesn't invoke schedule_delayed_work().
The original NULL pointer dereference case reported by MNC is now handled
by iscsi_target_do_login() doing a iscsi_target_sk_check_close() before
transitioning to FFP to determine when the socket has already closed,
or iscsi_target_start_negotiation() if the login needs to exchange
more PDUs (eg: iscsi_target_do_login returned 0) but the socket has
closed. For both of these cases, the cleanup up of remaining connection
resources will occur in iscsi_target_start_negotiation() from iscsi_np
process context once the failure is detected.
Finally, to handle to case where iscsi_target_sk_state_change() is
called after the initial PDU procesing is complete, it now invokes
conn->login_work -> iscsi_target_do_login_rx() to perform cleanup once
existing iscsi_target_sk_check_close() checks detect connection failure.
For this case, the cleanup of remaining connection resources will occur
in iscsi_target_do_login_rx() from delayed workqueue process context
once the failure is detected.

Commit b685d3d65ac7 "block: treat REQ_FUA and REQ_PREFLUSH as
synchronous" removed REQ_SYNC flag from WRITE_{FUA|PREFLUSH|...}
definitions. generic_make_request_checks() however strips REQ_FUA and
REQ_PREFLUSH flags from a bio when the storage doesn't report volatile
write cache and thus write effectively becomes asynchronous which can
lead to performance regressions
Fix the problem by making sure all bios which are synchronous are
properly marked with REQ_SYNC.

Pull pin control fixes from Linus Walleij:
"Here is an overdue pull request for pin control fixes, the most
prominent feature is to make Intel Chromebooks (and I suspect any
other Cherryview-based Intel thing) happy again, which we really want
to see.
There is a patch hitting drivers/firmware/* that I was uncertain to
who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
review tags on it and I trust them both 100% to do the right thing for
Intel platform drivers.
Summary:
- Make a few Intel Chromebooks with Cherryview DMI firmware work
smoothly.
- A fix for some bogus allocations in the generic group management
code.
- Some GPIO descriptor lookup table stubs. Merged through the pin
control tree for administrative reasons.
- Revert the "bi-directional" and "output-enable" generic properties:
we need more discussions around this. It seems other SoCs are using
input/output gate enablement and these terms are not correct.
- Fix mux and drive strength atomically in the MXS driver.
- Fix the SPDIF function on sunxi A83T.
- OF table terminators and other small fixes"

For ACPI devices which do not have a _PSC method, the ACPI subsys cannot
query their initial state at boot, so these devices are assumed to have
been put in D0 by the BIOS, but for touchscreens that is not always true.
This commit adds a call to acpi_device_fix_up_power to explicitly put
devices without a _PSC method into D0 state (for devices with a _PSC
method it is a nop). Note we only need to do this on probe, after a
resume the ACPI subsys knows the device is in D3 and will properly
put it in D0.
This fixes the SIS0817 i2c-hid touchscreen on a Peaq C1010 2-in-1
device failing to probe with a "hid_descr_cmd failed" error.

The Analogix 7737 DP to HDMI converter requires reduced M and N values
when to operate correctly at HBR2. We tried to reduce the M/N values for
all devices in commit 9a86cda07af2 ("drm/i915/dp: reduce link M/N
parameters"), but that regressed some other sinks. Detect this IC by its
OUI value of 0x0022B9 via the DPCD quirk list, and only reduce the M/N
values for that.

Face the fact, there are Display Port sink and branch devices out there
in the wild that don't follow the Display Port specifications, or they
have bugs, or just otherwise require special treatment. Start a common
quirk database the drivers can query based on the DP device
identification. At least for now, we leave the workarounds for the
drivers to implement as they see fit.
For starters, add a branch device that can't handle full 24-bit main
link Mdiv and Ndiv main link attributes properly. Naturally, the
workaround of reducing main link attributes for all devices ended up in
regressions for other devices. So here we are.

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. In this case, no initializers
are needed (they can be NULL initialized and callers adjusted to check
for NULL, which is more efficient than an indirect call).

Sabrina Dubroca reported an early panic:
BUG: unable to handle kernel paging request at ffffffffff240001
IP: efi_bgrt_init+0xdc/0x134
[...]
---[ end Kernel panic - not syncing: Attempted to kill the idle task!
... which was introduced by:
7b0a911478c7 ("efi/x86: Move the EFI BGRT init code to early init code")
The cause is that on this machine the firmware provides the EFI ACPI BGRT
table even on legacy non-EFI bootups - which table should be EFI only.
The garbage BGRT data causes the efi_bgrt_init() panic.
Add a check to skip efi_bgrt_init() in case non-EFI bootup to work around
this firmware bug.

Amongst its other duties, msm_gem_new_impl adds the newly created
GEM object to the shared inactive list which may also be actively
modifiying the list during submission. All the paths to modify
the list are protected by the mutex except for the one through
msm_gem_import which can end up causing list corruption.

Somehow the helper was never retrofitted for mdp5. Which meant when
plane_state->fence was added, it could get copied into new state in
mdp5_plane_duplicate_state().
If an update to disable the plane (for example on rmfb) managed to sneak
in after an nonblock update had swapped state, but before it was
committed, we'd get a splat:
