The bug in a workqueue leads to a stalled IO request in MQ ctx->rq_list

The underlying device is a null_blk, with default parameters:
queue_mode = MQ
submit_queues = 1
Verification that nullb0 has something inflight:
root@pserver8:~# cat /sys/block/nullb0/inflight
0 1
root@pserver8:~# find /sys/block/nullb0/mq/0/cpu* -name rq_list -print -exec cat {} \;
...
/sys/block/nullb0/mq/0/cpu2/rq_list
CTX pending:
ffff8838038e2400
...
During debug it became clear that stalled request is always inserted in
the rq_list from the following path:
save_stack_trace_tsk + 34
blk_mq_insert_requests + 231
blk_mq_flush_plug_list + 281
blk_flush_plug_list + 199
wait_on_page_bit + 192
__filemap_fdatawait_range + 228
filemap_fdatawait_range + 20
filemap_write_and_wait_range + 63
blkdev_fsync + 27
vfs_fsync_range + 73
blkdev_write_iter + 202
__vfs_write + 170
vfs_write + 169
kernel_write + 56
So blk_flush_plug_list() was called with from_schedule == true.
If from_schedule is true, that means that finally blk_mq_insert_requests()
offloads execution of __blk_mq_run_hw_queue() and uses kblockd workqueue,
i.e. it calls kblockd_schedule_delayed_work_on().
That means, that we race with another CPU, which is about to execute
__blk_mq_run_hw_queue() work.
Further debugging shows the following traces from different CPUs:
CPU#0 CPU#1
---------------------------------- -------------------------------
reqeust A inserted
STORE hctx->ctx_map[0] bit marked
kblockd_schedule...() returns 1
<schedule to kblockd workqueue>
request B inserted
STORE hctx->ctx_map[1] bit marked
kblockd_schedule...() returns 0
*** WORK PENDING bit is cleared ***
flush_busy_ctxs() is executed, but
bit 1, set by CPU#1, is not observed
As a result request B pended forever.
This behaviour can be explained by speculative LOAD of hctx->ctx_map on
CPU#0, which is reordered with clear of PENDING bit and executed _before_
actual STORE of bit 1 on CPU#1.
The proper fix is an explicit full barrier <mfence>, which guarantees
that clear of PENDING bit is to be executed before all possible
speculative LOADS or STORES inside actual work function.

Now GPIO IRQ loss is observed on dra7-evm after suspend/resume cycle
in the following case:
extcon_usb1(id_irq) -> pcf8575.gpio1 -> omapgpio6.gpio11 -> gic
the extcon_usb1 is wake up source and it enables IRQ wake up for
id_irq by calling enable/disable_irq_wake() during suspend/resume
which, in turn, causes execution of omap_gpio_wake_enable(). And
omap_gpio_wake_enable() will set/clear corresponding bit in
GPIO_IRQWAKEN_x register.
omapgpio6 configuration after boot - wakeup is enabled for GPIO IRQs
by default from omap_gpio_irq_type:
GPIO_IRQSTATUS_SET_0 | 0x00000400
GPIO_IRQSTATUS_CLR_0 | 0x00000400
GPIO_IRQWAKEN_0 | 0x00000400
GPIO_RISINGDETECT | 0x00000000
GPIO_FALLINGDETECT | 0x00000400
omapgpio6 configuration after after suspend/resume cycle:
GPIO_IRQSTATUS_SET_0 | 0x00000400
GPIO_IRQSTATUS_CLR_0 | 0x00000400
GPIO_IRQWAKEN_0 | 0x00000000 <---
GPIO_RISINGDETECT | 0x00000000
GPIO_FALLINGDETECT | 0x00000400
As result, system will start to lose interrupts from pcf8575 GPIO
expander, because when OMAP GPIO IP is in smart-idle wakeup mode, there
is no guarantee that transition(s) on input non wake up GPIO pin will
trigger asynchronous wake-up request to PRCM and then IRQ generation.
IRQ will be generated when GPIO is in active mode - for example, some
time after accessing GPIO bank registers IRQs will be generated
normally, but issue will happen again once PRCM will put GPIO in low
power smart-idle wakeup mode.
Note 1. Issue is not reproduced if debounce clk is enabled for GPIO
bank.
Note 2. Issue hardly reproducible if GPIO pins group contains both
wakeup/non-wakeup gpios - for example, it will be hard to reproduce
issue with pin2 if GPIO_IRQWAKEN_0=0x1 GPIO_IRQSTATUS_SET_0=0x3
GPIO_FALLINGDETECT = 0x3 (TRM "Power Saving by Grouping the Edge/Level
Detection").
Note 3. There nothing common bitween System wake up and OMAP GPIO bank
IP wake up logic - the last one defines how the GPIO bank ON-IDLE-ON
transition will happen inside SoC under control of PRCM.
Hence, fix the problem by removing omap_set_gpio_wakeup() function
completely and so keeping always in sync GPIO IRQ mask/unmask
(IRQSTATUS_SET) and wake up enable (GPIO_IRQWAKEN) bits; and adding
IRQCHIP_MASK_ON_SUSPEND flag in OMAP GPIO irqchip. That way non wakeup
GPIO IRQs will be properly masked/unmask by IRQ PM core during
suspend/resume cycle.

Don't read broken data after 'head' pointer.
Following commits will feed perf_evlist__mmap_read() with some 'head'
pointers not maintained by kernel. If 'head' pointer breaks an event, we
should avoid reading from the broken event. This can happen in backward
ring buffer.
For example:
old head
| |
V V
+---+------+----------+----+-----+--+
|..E|D....D|C........C|B..B|A....|E.|
+---+------+----------+----+-----+--+
'old' pointer points to the beginning of 'A' and trying read from it,
but 'A' has been overwritten. In this case, don't try to read from 'A',

If tracing_map_elt_alloc() fails, it will return ERR_PTR() instead of
NULL, so change the check to IS_ERROR(). We also need to set the
failed entry in the map->elts array to NULL instead of ERR_PTR() so
tracing_map_free_elts() doesn't try freeing an ERR_PTR().
tracing_map_free_elts() should also zero out what it frees so a
reentrant call won't find previously freed elements.

If both ACPI and DT platform descriptions are available, and the
kernel was configured at build time to support both flavours, the
default policy is to prefer DT over ACPI, and preferring ACPI over
DT while still allowing DT as a fallback is not possible.
Since some enterprise features (such as RAS) depend on ACPI, it may
be desirable for, e.g., distro installers to prefer ACPI boot but
fall back to DT rather than failing completely if no ACPI tables are
available.
So introduce the 'acpi=on' kernel command line parameter for arm64,
which signifies that ACPI should be used if available, and DT should
only be used as a fallback.

For this reason, all of the 7020, 7040, 8020 and 8040 include
armada-cp110-master.dtsi. When support for the second CP110 (slave)
used in 8020 and 8040 will be added, the .dtsi files for those SoCs
will in addition include armada-cp110-slave.dtsi.

The I2C controller found in the Marvell Armada 7K/8K provides the
bridge/offloading features, so the Device Tree should use the
marvell,mv78230-i2c compatible string instead of marvell,mv64xxx-i2c.

This commit slightly improves the description of the SPI flash
connected to the SPI controller of the Armada 7040, by:
- Using the more generic "jedec,spi-nor" compatible string, which
lets the driver auto-detect the exact SPI flash type.
- Removing the silly comment about the Chip Select, since reg = <0>
is explicit enough.
- Switching to the new Device Tree binding to describe flash
partitions.

This commit adds the necessary UART aliases to the main Armada 7K/8K
.dtsi file, and uses them to define the /chosen/stdout-path property
on the Armada 7040 DB board.

Node names should not contain an instance number, the unit address
serves to distinguish nodes of the same name. So rename the XOR nodes
to just xor@<address>.

[Thomas:
- remove labels, they are really not needed for XOR engines.
- remove the Fixes: tag, as this is not a fix.]
