b84449dc14 Merge branch 'parisc-4.15-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:

 - Many small fixes to show the real physical addresses of devices
   instead of hashed addresses.

 - One important fix to unbreak 32-bit SMP support: We forgot to 16-byte
   align the spinlocks in the assembler code.

 - Qemu support: The host will get a chance to sleep when the parisc
   guest is idle. We use the same mechanism as the power architecture by
   overlaying the "or %r10,%r10,%r10" instruction which is simply a nop
   on real hardware.

7b6af2c531 leds: core: Fix regression caused by commit 2b83ff96f5
Commit 2b83ff96f5 ("led: core: Fix brightness setting when setting delay_off=0")
replaced del_timer_sync(&led_cdev->blink_timer) with led_stop_software_blink()
in led_blink_set(), which additionally clears LED_BLINK_SW flag as well as
zeroes blink_delay_on and blink_delay_off properties of the struct led_classdev.

Cleansing of the latter ones wasn't required to fix the original issue but
wasn't considered harmful. It nonetheless turned out to be so in case when
pointer to one or both props is passed to led_blink_set() like in the
ledtrig-timer.c. In such cases zeroes are passed later in delay_on and/or
delay_off arguments to led_blink_setup(), which results either in stopping
the software blinking or setting blinking frequency always to 1Hz.

Avoid using led_stop_software_blink() and add a single call required
to clear LED_BLINK_SW flag, which was the only needed modification to
fix the original issue.

fee4380f36 mtd: nand: pxa3xx: Fix READOOB implementation
In the current driver, OOB bytes are accessed in raw mode, and when a
page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the
driver must read the whole spare area (64 bytes in case of a 2k page,
16 bytes for a 512 page). The driver was only reading the free OOB
bytes, which was leaving some unread data in the FIFO and was somehow
leading to a timeout.

We could patch the driver to read ->spare_size + ->ecc_size instead of
just ->spare_size when READOOB is requested, but we'd better make
in-band and OOB accesses consistent.
Since the driver is always accessing in-band data in non-raw mode (with
the ECC engine enabled), we should also access OOB data in this mode.
That's particularly useful when using the BCH engine because in this
mode the free OOB bytes are also ECC protected.

Fixes: 43bcfd2bb2 ("mtd: nand: pxa3xx: Add driver-specific ECC BCH support")

107b7d9fa9 mfd: rtsx: Release IRQ during shutdown
'Commit cc27b735ad ("PCI/portdrv: Turn off PCIe services during
shutdown")' revealed a resource leak in rtsx_pci driver during shutdown.

Issue shows up as a warning during shutdown as follows:

remove_proc_entry: removing non-empty directory 'irq/17', leaking at least
'rtsx_pci'
WARNING: CPU: 0 PID: 1578 at fs/proc/generic.c:572
remove_proc_entry+0x11d/0x130

mp_unmap_irq
acpi_unregister_gsi_apic
acpi_pci_irq_disable
do_pci_disable_device

device_shutdown
kernel_restart
Sys_reboot

Even though rtsx_pci driver implements a shutdown callback, it is not
releasing the interrupt that it registered during probe. This is causing
the ACPI layer to complain that the shared IRQ is in use while freeing
IRQ.

This code releases the IRQ to prevent resource leak and eliminate the
warning.

e1915c8195 ARM: SoC fixes for 4.15
Fixes this time include mostly device tree changes, as usual,
 the notable ones include:
 
 - A number of patches to fix most of the remaining DTC warnings
   that got introduced when DTC started warning about some
   obvious mistakes. We still have some remaining warnings that
   probably may have to wait until 4.16 to get fixed while we
   try to figure out what the correct contents should be.
 - On Allwinner A64, Ethernet PHYs need a fix after a mistake in
   coordination between patches merged through multiple branches.
 - Various fixes for PMICs on allwinner based boards
 - Two fixes for ethernet link detection on some Renesas machines
 - Two stability fixes for rockchip based boards
 
 Aside from device-tree, two other areas got fixes for older
 problems:
 
 - For TI Davinci DM365, a couple of fixes were needed to repair
   the MMC DMA engine support, apparently this has been broken for
   a while.
 - One important fix for all Allwinner chips with the PMIC driver
   as a loadable module.

d84baa5a62 Allwinner fixes for 4.15
First, one fix that adds proper regulator references for the EMAC
 external PHYs on A64 boards. The EMAC bindings were developed for 4.13,
 but reverted at the last minute. They were finalized and brought back
 for 4.15. However in the time between, regulator support for the A64
 boards was merged. When EMAC device tree changes were reintroduced,
 this was not taken into account.
 
 Second, a patch that adds OF based modalias uevent for RSB slave devices.
 This has been missing since the introduction of RSB, and recently with
 PMIC regulator support introduced for the A64, has been seen affecting
 distributions, which have the all-important PMIC mfd drivers built as
 modules, which then don't get loaded.
 
 Other minor cleanups include final conversion of raw indices to CCU
 binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the
 A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero
 Plus2, and adding a missing compatible for the PMIC on the TBS A711
 tablet.

30414f3010 drm/i915: Apply Display WA #1183 on skl, kbl, and cfl
Display WA #1183 was recently added to workaround
"Failures when enabling DPLL0 with eDP link rate 2.16
or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz
(CDCLK_CTL CD Frequency Select 10b or 11b) used in this
 enabling or in previous enabling."

This workaround was designed to minimize the impact only
to save the bad case with that link rates. But HW engineers
indicated that it should be safe to apply broadly, although
they were expecting the DPLL0 link rate to be unchanged on
runtime.

We need to cover 2 cases: when we are in fact enabling DPLL0
and when we are just changing the frequency with small
differences.

This is based on previous patch by Rodrigo Vivi with suggestions
from Ville Syrjälä.

f24c4d4780 efi/capsule-loader: Reinstate virtual capsule mapping
Commit:

  82c3768b8d ("efi/capsule-loader: Use a cached copy of the capsule header")

... refactored the capsule loading code that maps the capsule header,
to avoid having to map it several times.

However, as it turns out, the vmap() call we ended up removing did not
just map the header, but the entire capsule image, and dropping this
virtual mapping breaks capsules that are processed by the firmware
immediately (i.e., without a reboot).

Unfortunately, that change was part of a larger refactor that allowed
a quirk to be implemented for Quark, which has a non-standard memory
layout for capsules, and we have slightly painted ourselves into a
corner by allowing quirk code to mangle the capsule header and memory
layout.

So we need to fix this without breaking Quark. Fortunately, Quark does
not appear to care about the virtual mapping, and so we can simply
do a partial revert of commit:

  2a457fb31d ("efi/capsule-loader: Use page addresses rather than struct page pointers")

... and create a vmap() mapping of the entire capsule (including header)
based on the reinstated struct page array, unless running on Quark, in
which case we pass the capsule header copy as before.

563b5cbe33 iommu/arm-smmu-v3: Cope with duplicated Stream IDs
For PCI devices behind an aliasing PCIe-to-PCI/X bridge, the bridge
alias to DevFn 0.0 on the subordinate bus may match the original RID of
the device, resulting in the same SID being present in the device's
fwspec twice. This causes trouble later in arm_smmu_write_strtab_ent()
when we wind up visiting the STE a second time and find it already live.

Avoid the issue by giving arm_smmu_install_ste_for_dev() the cleverness
to skip over duplicates. It seems mildly counterintuitive compared to
preventing the duplicates from existing in the first place, but since
the DT and ACPI probe paths build their fwspecs differently, this is
actually the cleanest and most self-contained way to deal with it.

8a9bd4f8eb s390/dasd: fix wrongly assigned configuration data
We store per path and per device configuration data to identify the
path or device correctly. The per path configuration data might get
mixed up if the original request gets into error recovery and is
started with a random path mask.

This would lead to a wrong identification of a path in case of a CUIR
event for example.

Fix by copying the path mask from the original request to the error
recovery request in case it is a path verification request.

df29c9db8a omapdrm/dss/hdmi4_cec: fix interrupt handling
The omap4 CEC hardware cannot tell a Nack from a Low Drive from an
Arbitration Lost error, so just report a Nack, which is almost
certainly the reason for the error anyway.

This also simplifies the implementation. The only three interrupts
that need to be enabled are:

Transmit Buffer Full/Empty Change event: triggered when the
transmit finished successfully and cleared the buffer.

Receiver FIFO Not Empty event: triggered when a message was received.

Frame Retransmit Count Exceeded event: triggered when a transmit
failed repeatedly, usually due to the message being Nacked. Other
reasons are possible (Low Drive, Arbitration Lost) but there is no
way to know. If this happens the TX buffer needs to be cleared
manually.

While testing various error conditions I noticed that the hardware
can receive messages up to 18 bytes in total, which exceeds the legal
maximum of 16. This could cause a buffer overflow, so we check for
this and constrain the size to 16 bytes.

The old incorrect interrupt handler could cause the CEC framework to
enter into a bad state because it mis-detected the "Start Bit Irregularity
event" as an ARB_LOST transmit error when it actually is a receive error
which should be ignored.

eda41bdc57 drm/i915: Put all non-blocking modesets onto an ordered wq
We have plenty of global registers and whatnot programmed without

modesets are allowed to execute in parallel which could corrupt
said registers.

To avoid the problem let's run all non-blocking modesets on an
ordered workqueue. We still put page flips etc. to system_unbound_wq
allowing page flips on one pipe to execute in parallel with page flips
or a modeset on a another pipe (assuming no known state is shared
between them, at which point they would have been added to the same
atomic commit and serialized that way).

Blocking modesets are already serialized with each other by
connection_mutex, and thus are safe. To serialize them with
non-blocking modesets we just flush the workqueue before executing
blocking modesets.

Pull irq fixes from Thomas Gleixner:
 "A rather large update after the kaisered maintainer finally found time
  to handle regression reports.

   - The larger part addresses a regression caused by the x86 vector
     management rework.

     The reservation based model does not work reliably for MSI
     interrupts, if they cannot be masked (yes, yet another hw
     engineering trainwreck). The reason is that the reservation mode
     assigns a dummy vector when the interrupt is allocated and switches
     to a real vector when the interrupt is requested.

     If the MSI entry cannot be masked then the initialization might
     raise an interrupt before the interrupt is requested, which ends up
     as spurious interrupt and causes device malfunction and worse. The
     fix is to exclude MSI interrupts which do not support masking from
     reservation mode and assign a real vector right away.

   - Extend the extra lockdep class setup for nested interrupts with a
     class for the recently added irq_desc::request_mutex so lockdep can
     differeniate and does not emit false positive warnings.

   - A ratelimit guard for the bad irq printout so in case a bad irq
     comes back immediately the system does not drown in dmesg spam"

a31e58e129 x86/apic: Switch all APICs to Fixed delivery mode
Some of the APIC incarnations are operating in lowest priority delivery
mode. This worked as long as the vector management code allocated the same
vector on all possible CPUs for each interrupt.

Lowest priority delivery mode does not necessarily respect the affinity
setting and may redirect to some other online CPU. This was documented
somewhere in the old code and the conversion to single target delivery
missed to update the delivery mode of the affected APIC drivers which
results in spurious interrupts on some of the affected CPU/Chipset
combinations.

Switch the APIC drivers over to Fixed delivery mode and remove all
leftovers of lowest priority delivery mode.

Switching to Fixed delivery mode is not a problem on these CPUs because the
kernel already uses Fixed delivery mode for IPIs. The reason for this is
that th SDM explicitely forbids lowest prio mode for IPIs. The reason is
obvious: If the irq routing does not honor destination targets in lowest
prio mode then an IPI targeted at CPU1 might end up on CPU0, which would be
a fatal problem in many cases.

As a consequence of this change, the apic::irq_delivery_mode field is now
pointless, but this needs to be cleaned up in a separate patch.
