Pull irq fixes from Thomas Gleixner:
"Three fixes for irq core and irq chip drivers:
- Do not set the irq type if type is NONE. Fixes a boot regression
on various SoCs
- Use the proper cpu for setting up the GIC target list. Discovered
by the cpumask debugging code.
- A rather large fix for the MIPS-GIC so per cpu local interrupts
work again. This was discovered late because the code falls back
to slower timers which use normal device interrupts"

Commit 815806e39bf6 ("regmap: drop cache if the bus transfer error")
added a call to regcache_drop_region() to error path in
_regmap_raw_write(). However that path runs with regmap lock taken,
and regcache_drop_region() tries to re-take it, causing a deadlock.
Fix that by calling map->cache_ops->drop() directly.

the eg20t driver call request_irq() function before the pch_base_address,
base address of i2c controller's register, is assigned an effective value.
there is one possible scenario that an interrupt which isn't inside eg20t
arrives immediately after request_irq() is executed when i2c controller
shares an interrupt number with others. since the interrupt handler
pch_i2c_handler() has already active as shared action, it will be called
and read its own register to determine if this interrupt is from itself.
At that moment, since base address of i2c registers is not remapped
in kernel space yet,so the INT handler will access an illegal address
and then a error occurs.

Since the device hierarchy domain was added by commit c98c1822ee13
("irqchip/mips-gic: Add device hierarchy domain"), GIC local interrupts
have been broken.
Users attempting to setup a per-cpu local IRQ, for example the GIC timer
clock events code in drivers/clocksource/mips-gic-timer.c, the
setup_percpu_irq function would refuse with -EINVAL because the GIC
irqchip driver never called irq_set_percpu_devid so the
IRQ_PER_CPU_DEVID flag was never set for the IRQ. This happens because
irq_set_percpu_devid was being called from the gic_irq_domain_map
function which is no longer called.
Doing only that runs into further problems because gic_dev_domain_alloc
set the struct irq_chip for all interrupts, local or shared, to
gic_level_irq_controller despite that only being suitable for shared
interrupts. The typical outcome of this is that gic_level_irq_controller
callback functions are called for local interrupts, and then hwirq
number calculations overflow & the driver ends up attempting to access
some invalid register with an address calculated from an invalid hwirq
number. Best case scenario is that this then leads to a bus error. This
is fixed by abstracting the setup of the hwirq & chip to a new function
gic_setup_dev_chip which is used by both the root GIC IRQ domain & the
device domain.
Finally, decoding local interrupts failed because gic_dev_domain_alloc
only called irq_domain_alloc_irqs_parent for shared interrupts. Local
ones were therefore never associated with hwirqs in the root GIC IRQ
domain and the virq in gic_handle_local_int would always be 0. This is
fixed by calling irq_domain_alloc_irqs_parent unconditionally & having
gic_irq_domain_alloc handle both local & shared interrupts, which is
easy due to the aforementioned abstraction of chip setup into
gic_setup_dev_chip.
This fixes use of the MIPS GIC timer for clock events, which has been
broken since c98c1822ee13 ("irqchip/mips-gic: Add device hierarchy
domain") but hadn't been noticed due to a silent fallback to the MIPS
coprocessor 0 count/compare clock events device.

The FW command output length should be only the length of struct

gic_raise_softirq() walks the list of cpus using for_each_cpu(), it calls
gic_compute_target_list() which advances the iterator by the number of
CPUs in the cluster.
If gic_compute_target_list() reaches the last CPU it leaves the iterator
pointing at the last CPU. This means the next time round the for_each_cpu()
loop cpumask_next() will be called with an invalid CPU.
This triggers a warning when built with CONFIG_DEBUG_PER_CPU_MAPS:

As reported by Alexey Khoroshilov (https://lkml.org/lkml/2016/9/9/737):
riocm_send_close() is called from rio_cm_shutdown() under
spin_lock_bh(idr_lock), but riocm_send_close() uses a GFP_KERNEL
allocation.
Fix by taking riocm_send_close() outside of spinlock protected code.

Pull exynos and one stable ABI fix from Dave Airlie:
"One important drm 32/64 ABI fix came in so I'll dequeue what I have,
the rest is just exynos runtime pm fixes, but the net removal of code
seems like a win to me.
I'm going to be sporadic this week due to school holidays, so if
anything urgent turns up, Daniel will take care of it"

Fix a regression caused by commit 2bc46b3ad3c1 ("[media] media/pci:
convert drivers to use the new vb2_queue dev field").
Three places where q->dev should be set were missed, causing

On a imx6ul-pico board the following error is seen during system suspend:
dpm_run_callback(): platform_pm_resume+0x0/0x54 returns -110
PM: Device 2090000.flexcan failed to resume: error -110
The reason for this suspend error is because when the CAN interface is not
active the clocks are disabled and then flexcan_chip_enable() will
always fail due to a timeout error.
In order to fix this issue, only call flexcan_chip_enable/disable()
when the CAN interface is active.
Based on a patch from Dong Aisheng in the NXP kernel.

commit a894cf6c5a82 ("mtd: nand: mxc: switch to mtd_ooblayout_ops")
introduced a regression accessing the OOB area from the mxc_nand
driver due to an Obiwan error in the mxc_nand_v[12]_ooblayout_free()
functions. They report a bogus oobregion { 64, 7 } which leads to
errors accessing bogus data when reading the oob area.
Prior to the commit the mtd-oobtest module could be run without any
errors. With the offending commit, this test fails with results like:

When mtk_nfc_do_write_page() comparing the sector number,because the
sector number field is at the 12th-bit position of NFI_BYTELEN
register,the masked register should be shifted 12 bits before being
compared.The result of this bug may cause the second subpage has
incomplete ECC parity bytes.

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

MAC devices use the RWKPKTEN and MGKPKTEN bits of the PMT Control/Status
register to generate power management events.
So this patch is to properly set the RWKPKTEN [BIT(2)] inside the
PMT register (needed in case of global unicast).

When CONFIG_PM is not set, we get a warning about an unused function:
drivers/gpu/drm/exynos/exynos_drm_gsc.c:1219:12: error: 'gsc_clk_ctrl' defined but not used [-Werror=unused-function]
static int gsc_clk_ctrl(struct gsc_context *ctx, bool enable)
^~~~~~~~~~~~
This removes the two #ifdef checks in this file and instead marks the
functions as __maybe_unused, which is a more reliable way of doing the
same, allowing better build coverage and avoiding the warning above.
