git commit 1ec2772e0c3c ("s390/diag: add a statistic for diagnose
calls") added function calls to gather diagnose statistics.
In case of the dasd diag driver the function call was added between a
register asm statement which initialized register r2 and the inline
assembly itself. The function call clobbers the contents of register
r2 and therefore the diag 0x250 call behaves in a more or less random
way.
Fix this by extracting the function call into a separate function like
we do everywhere else.

Commit d07e22597d1d ("mm: mmap: add new /proc tunable for mmap_base
ASLR") added the ability to choose from a range of values to use for
entropy count in generating the random offset to the mmap_base address.
The maximum value on this range was set to 32 bits for 64-bit x86
systems, but this value could be increased further, requiring more than
the 32 bits of randomness provided by get_random_int(), as is already
possible for arm64. Add a new function: get_random_long() which more
naturally fits with the mmap usage of get_random_int() but operates
exactly the same as get_random_int().
Also, fix the shifting constant in mmap_rnd() to be an unsigned long so
that values greater than 31 bits generate an appropriate mask without
overflow. This is especially important on x86, as its shift instruction
uses a 5-bit mask for the shift operand, which meant that any value for
mmap_rnd_bits over 31 acts as a no-op and effectively disables mmap_base
randomization.
Finally, replace calls to get_random_int() with get_random_long() where
appropriate.
This patch (of 2):
Add get_random_long().

This driver uses PCI glue that is only available on 32-bit ARM. This used
to work fine as long as ARCH_MVEBU and ARCH_DOVE were exclusively 32-bit,
but there's a patch in the pipe to make ARCH_MVEBU also available on 64-bit
ARM.

991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq() and
pcibios_free_irq()") appeared in v4.3 and helps support IOAPIC hotplug.
Олег reported that the Elcus-1553 TA1-PCI driver worked in v4.2 but not
v4.3 and bisected it to 991de2e59090. Sunjin reported that the RocketRAID
272x driver worked in v4.2 but not v4.3. In both cases booting with
"pci=routirq" is a workaround.
I think the problem is that after 991de2e59090, we no longer call
pcibios_enable_irq() for upstream bridges. Prior to 991de2e59090, when a
driver called pci_enable_device(), we recursively called
pcibios_enable_irq() for upstream bridges via pci_enable_bridge().
After 991de2e59090, we call pcibios_enable_irq() from pci_device_probe()
instead of the pci_enable_device() path, which does *not* call
pcibios_enable_irq() for upstream bridges.
Revert 991de2e59090 to fix these driver regressions.

also run during early init when that's not available yet and caused
some systems to crash on boot for this reason along with a cleanup
on top of it (Rafael Wysocki).

Pull libnvdimm fixes from Dan Williams:
- Two fixes for compatibility with the ACPI 6.1 specification.
Without these fixes multi-interface DIMMs will fail to be probed, and
address range scrub commands to find memory errors will give results
that the kernel will mis-interpret. For multi-interface DIMMs Linux
will accept either the original 6.0 implementation or 6.1.
For address range scrub we'll only support 6.1 since ACPI formalized
this DSM differently than the original example [1] implemented in
v4.2. The expectation is that production systems will only ever ship
the ACPI 6.1 address range scrub command definition.
- The wider async address range scrub work targeting 4.6 discovered
that the original synchronous implementation in 4.5 is not sizing its
return buffer correctly.
- Arnd caught that my recent fix to the size of the pfn_t flags missed
updating the flags variable used in the pmem driver.
- Toshi found that we mishandle the memremap() return value in
devm_memremap().

CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms
(which are DT based and multi-platform), but also on a select set of
Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence
since commit 0ba58de231066e47 ("drivers: sh: Get rid of
CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer
installed on these SuperH platforms, and module clocks may not be
enabled when needed, leading to driver failures.
To fix this, add an additional check for CONFIG_OF.

"9.20.7 NVDIMM Root Device _DSMs"
Changes include:
1/ New 'restart' fields in ars_status, unfortunately these are
implemented in the middle of the existing definition so this change
is not backwards compatible. The expectation is that shipping
platforms will only ever support the ACPI 6.1 definition.
2/ New status values for ars_start ('busy') and ars_status ('overflow').

When working in Dual Role Device mode, USB state machine is not kicked,
when host or gadget drivers are loaded. Fix this be explicitly triggering
state detection on client driver load.
Issue is that if the board is booted without micro usb cable and usb
device attached, kernel fails to populate the usb host and device.
The reason for this is that the state machine worker logic only checks
for USB_DR_MODE_PERIPHERAL and USB_DR_MODE_HOST modes to run worker
thread. However if the phy is configured in OTG mode it would fail
to run the state machine, resulting in failure to detect for very
first time.
This patch fixes the issue by removing the explicit checks.
Issue is noticed on Qualcomm Dragon board DB410C.

As the code in this file is being executed within irq context in some
cases, we must avoid the clk_get_rate which uses mutex internally.
Switch the code to use clk_hw_get_rate instead which is non-locking.
This fixes an issue where PM runtime will hang the system if enabled
with a serial console before a suspend-resume cycle.

Pull rdma fixes from Doug Ledford:
"One ocrdma fix:
- The new CQ API support was added to ocrdma, but they got the arming
logic wrong, so without this, transfers eventually fail when they
fail to arm the interrupt properly under load
Two related fixes for mlx4:
- When we added the 64bit extended counters support to the core IB
code, they forgot to update the RoCE side of the mlx4 driver (the
IB side they properly updated).
I debated whether or not to include these patches as they could be
considered feature enablement patches, but the existing code will
blindy copy the 32bit counters, whether any counters were requested
at all (a bug).
These two patches make it (a) check to see that counters were
requested and (b) copy the right counters (the 64bit support is
new, the 32bit is not). For that reason I went ahead and took
them"

It has been observed that sometimes disabling the dc6 fails
and dc6 state pops back up, brief moment after disabling. This
has to be dmc save/restore timing issue or other bug in the
way dc states are handled.
Try to work around this issue as we don't have firmware fix
yet available. Verify that the value we wrote for the dmc sticks,
and also enforce it by rewriting it, if it didn't.

set_power_state defaults to no displays, so we need to update
the display configuration after setting up the powerstate on the
first call. In most cases this is not an issue since ends up
getting called multiple times at any given modeset and the proper
order is achieved in the display changed handling at the top of
the function.
