git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip updates for 4.14-rc5 from Marc Zyngier:
- Fix unfortunate mistake in the GICv3 ITS binding example
- Two fixes for the recently merged GICv4 support
- GICv3 ITS 52bit PA fixes
- Generic irqchip mask-ack fix, and its application to the tango irqchip

Add device-id entry for (Honeywell) Metrologic MS7820 bar code scanner.
The device has two interfaces (in this mode?); a vendor-specific
interface with two interrupt endpoints and a second HID interface, which
we do not bind to.

In bnxt_find_nvram_item(), it is copying firmware response data after
releasing the mutex. This can cause the firmware response data
to be corrupted if the next firmware response overwrites the response
buffer. The rare problem shows up when running ethtool -i repeatedly.
Fix it by calling the new variant _hwrm_send_message_silent() that requires
the caller to take the mutex and to release it after the response data has
been copied.

As a further improvement to the PF/VF link change logic, use a private
mutex instead of the rtnl lock to protect link change logic. With the
new mutex, we don't have to take the rtnl lock in the workqueue when
we have to handle link related functions. If the VF and PF drivers
are running on the same host and both take the rtnl lock and one is
waiting for the other, it will cause timeout. This patch fixes these
timeouts.

Link status query firmware messages originating from the VFs are forwarded
to the PF. The driver handles these interactions in a workqueue for the
VF and PF. The VF driver waits for the response from the PF in the
workqueue. If the PF and VF driver are running on the same host and the
work for both PF and VF are queued on the same workqueue, the VF driver
may not get the response if the PF work item is queued behind it on the
same workqueue. This will lead to the VF link query message timing out.
To prevent this, we create a private workqueue for PFs instead of using
the common workqueue. The VF query and PF response will never be on
the same workqueue.

The 88E6060 Ethernet switch always transmits the multicast bit of the
switch MAC address as a zero. It re-uses the corresponding bit 8 of the
register "Switch MAC Address Register Bytes 0 & 1" for "DiffAddr".
If the "DiffAddr" bit is 0, then all ports transmit the same source
address. If it is set to 1, then bit 2:0 are used for the port number.
The mv88e6060 driver is currently wrongly shifting the MAC address byte
0 by 9. To fix this, shift it by 8 as usual and clear its bit 0.

We have seen NULL-pointer dereference crashes in tty->disc_data when the
N_TTY fallback driver failed to open during hangup. The immediate cause
of this open to fail has been addressed in the preceding patch to
vmalloc(), but this code could be more robust.
As Alan pointed out in commit 8a8dabf2dd68 ("tty: handle the case where
we cannot restore a line discipline"), the N_TTY driver, historically
the safe fallback that could never fail, can indeed fail, but the
surrounding code is not prepared to handle this. To avoid crashes he
added a new N_NULL driver to take N_TTY's place as the last resort.
Hook that fallback up to the hangup path. Update tty_ldisc_reinit() to
reflect the reality that n_tty_open can indeed fail.

When I execute numactl -H (which reads /sys/devices/system/node/nodeX/cpumap
and displays cpumask_of_node for each node), I get different result
on X86 and arm64. For each numa node, the former only displayed online
CPUs, and the latter displayed all possible CPUs. Unfortunately, both
Linux documentation and numactl manual have not described it clear.
I sent a mail to ask for help, and Michal Hocko replied that he
preferred to print online cpus because it doesn't really make much sense
to bind anything on offline nodes.
Will said:
"I suspect the vast majority (if not all) code that reads this file was
developed for x86, so having the same behaviour for arm64 sounds like
something we should do ASAP before people try to special case with
things like #ifdef __aarch64__. I'd rather have this in 4.14 if
possible."

SMBUS_BLOCK_DATA transactions might fail due to a race condition with
the IMC (Integrated Micro Controller), even when the IMC semaphore
is used.
This bug has been reported and confirmed by AMD, who suggested as a
solution an IMC firmware upgrade (obtained via BIOS update) and
disabling the IMC during SMBUS_BLOCK_DATA transactions.
Even without the IMC upgrade, the SMBUS is much more stable with this
patch.

Commit b6c159a9cb69 ("i2c: ismt: Don't duplicate the receive length for
block reads") broke I2C block reads. It aimed to fix normal SMBus block
read, but changed the correct behavior of I2C block read in the process.
According to Documentation/i2c/smbus-protocol, one vital difference
between normal SMBus block read and I2C block read is that there is no
byte count prefixed in the data sent on the wire:
SMBus Block Read: i2c_smbus_read_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Count] A [Data] A [Data] A ... A [Data] NA P
I2C Block Read: i2c_smbus_read_i2c_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Data] A [Data] A ... A [Data] NA P
Therefore the two transaction types need to be processed differently in
the driver by copying of the dma_buffer as done previously for the
I2C_SMBUS_I2C_BLOCK_DATA case.

The driver had a type mismatch since it was first merged, but
this never caused problems because it is only built on 64-bit
architectures that define timespec and timespec64 to the same

If we ever want to compile-test the driver on 32-bit or change
the way that 64-bit timespec64 is defined, we need to fix it,
so let's just do it now.

The current ITS driver works fine as long as normal memory and GICR
regions are located within the lower 48bit (>=0 && <2^48) physical
address space. Some of the registers GICR_PEND/PROP, GICR_VPEND/VPROP
and GITS_CBASER are handled properly but not all when configuring
the hardware with 52bit physical address.
This patch does the following changes to support 52bit PA.
-Handle 52bit PA in GITS_BASERn.
-Fix ITT_addr width to 52bits, bits[51:8].
-Fix RDbase width to 52bits, bits[51:16].
-Fix VPT_addr width to 52bits, bits[51:16].
Definition of the GITS_BASERn register when ITS PageSize is 64KB:
-Bits[47:16] of the register provide bits[47:16] of the table PA.
-Bits[15:12] of the register provide bits[51:48] of the table PA.
-Bits[15:00] of the base physical address are 0.

The VCPU table consists of vPE entries, and its size provides the number
of VPEs supported by GICv4 hardware. Unfortunately the maximum size of
the VPE table is not discoverable like Device table. All VLPI commands
limits the number of bits to 16 to hold VPEID, which is index into VCPU
table. Don't apply DEVID bits for VCPU table instead assume maximum bits
to 16.

The driver probe path hits 'BUG_ON(entries != vpe_proxy.dev->nr_ites)'
on systems where it has VLPI capability, doesn't support direct LPI
feature and boot with a single CPU.
Relax the BUG_ON() condition to fix the issue.

drm/imx: i.MX5 regression fix and i.MX6QP PRE/PRG stability fixes
- Disable channel burst locking on IPUv3EX (i.MX51) and IPUv3M (i.MX53).
This fixes a regression introduced by commit 790cb4c7c954 ("drm/imx: lock
scanout transfers for consecutive bursts").
- Give PRG a head start. Waiting for both double buffers to fill up before
enabling the IPU improves startup reliability.
- Avoid PRE control register updates during unsafe window, workaround for
ERR009624.

of_fwnode_graph_get_port_parent()
Using CONFIG_OF_DYNAMIC=y uncovered an imbalance in the usecount of the
node being passed to of_fwnode_graph_get_port_parent(). Preserve the
usecount by using of_get_parent() instead of of_get_next_parent() which
don't decrement the usecount of the node passed to it.

There are two types of memory reservations firmware can ask the kernel
to make in the device tree: static and dynamic.
See Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
If you have greater than 16 entries in /reserved-memory (as we do on
POWER9 systems) you would get this scary looking error message:
[ 0.000000] OF: reserved mem: not enough space all defined regions.
This is harmless if all your reservations are static (which with OPAL on
POWER9, they are).
It is not harmless if you have any dynamic reservations after the 16th.
In the first pass over the fdt to find reservations, the child nodes of
/reserved-memory are added to a static array in of_reserved_mem.c so that
memory can be reserved in a 2nd pass. The array has 16 entries. This is why,
on my dual socket POWER9 system, I get that error 4 times with 20 static
reservations.
We don't have a problem on ppc though, as in arch/powerpc/kernel/prom.c
we look at the new style /reserved-ranges property to do reservations,
and this logic was introduced in 0962e8004e974 (well before any powernv
system shipped).
A Google search shows up no occurances of that exact error message, so we're
probably safe in that no machine that people use has memory not being reserved
when it should be.
The simple fix is to bump the length of the array to 32 which "should be
enough for everyone(TM)". The simple fix of not recording static allocations
in the array would cause problems for devices with "memory-region" properties.
A more future-proof fix is likely possible, although more invasive and this
simple fix is perfectly suitable in the meantime while a more future-proof
fix is developed.

Do not strdup() console options. It seems that the only reason for
it to be strdup()-ed was a compilation warning: printk, UART and
console drivers, for some reason, expect char pointer instead of
const char pointer. So we can just pass `of_stdout_options', but
need to cast it to char pointer. A better fix would be to change
printk, console drivers and UART to accept const char `options';
but that will take time - there are lots of drivers to update.
The patch also fixes a possible memory leak: add_preferred_console()
can fail, but we don't kfree() options.

While converting mdp5_enable/disable() calls to pm_runtime_get/put() API,
an extra call to pm_runtime_put_autosuspend() crept in
mdp5_crtc_cursor_set(). This results in calling the suspend handler
twice, and therefore clk_disables twice, which isn't a nice thing to do.

The DSI runtime PM suspend/resume callbacks check whether
msm_host->cfg_hnd is non-NULL before trying to enable the bus clocks.
This is done to accommodate early calls to these functions that may
happen before the bus clocks are even initialized.
Calling pm_runtime_put_autosuspend() in dsi_host_init() can result in
racy behaviour since msm_host->cfg_hnd is set very soon after. If the
suspend callback happens too late, we end up trying to disable clocks
that were never enabled, resulting in a bunch of WARN_ON splats.
Use pm_runtime_put_sync() so that the suspend callback is called
immediately.
