If ->get_regs_len() callback return 0, we allocate 0 bytes of memory,
what print ugly warning in dmesg, which can be found further below.
This happen on mac80211 devices where ieee80211_get_regs_len() just
return 0 and driver only fills ethtool_regs structure and actually
do not provide any dump. However I assume this can happen on other
drivers i.e. when for some devices driver provide regs dump and for
others do not. Hence preventing to to print warning in ethtool code
seems to be reasonable.

In the latest version of the IPv6 Segment Routing IETF draft [1] the
cleanup flag is removed and the flags field length is shrunk from 16 bits
to 8 bits. As a consequence, the input of the HMAC computation is modified
in a non-backward compatible way by covering the whole octet of flags
instead of only the cleanup bit. As such, if an implementation compatible
with the latest draft computes the HMAC of an SRH who has other flags set
to 1, then the HMAC result would differ from the current implementation.
This patch carries those modifications to prevent conflict with other
implementations of IPv6 SR.

Moved the READ and WRITE switch cases to the top. Added a default
case to the switch case and replaced duplicate scsi result value with a
macro.
The idea is that since most of scsi commands we care about performance
wise are read or write, we need to process them first.
Internally the compiler (GCC) converts a switch case into either a jump
table or a bunch of if else conditions, so placing the often used read,
write cases at the top is an effort in optimization.

The lockdep splat below hints at a bug in RCU usage in dm-crypt that
was introduced with commit c538f6ec9f56 ("dm crypt: add ability to use
keys from the kernel key retention service"). The kernel keyring
function user_key_payload() is in fact a wrapper for
rcu_dereference_protected() which must not be called with only
rcu_read_lock() section mark.
Unfortunately the kernel keyring subsystem doesn't currently provide
an interface that allows the use of an RCU read-side section. So for
now we must drop RCU in favour of rwsem until a proper function is
made available in the kernel keyring subsystem.

The protected cache ops contain no out of line fixup code to return an
error code in the event of a fault, with the cache op being skipped in
that case. For KVM however we'd like to detect this case as page
faulting will be disabled so it could happen during normal operation if
the GVA page tables were flushed, and need to be handled by the caller.
Add the out-of-line fixup code to load the error value -EFAULT into the
return variable, and adapt the protected cache line functions to pass
the error back to the caller.

- invalid_pmd_table is used by pud_present(), pud_none(), and

Driver for interrupt combiners in the Top-level Control and Status
Registers (TCSR) hardware block in Qualcomm Technologies chips.
An interrupt combiner in this block combines a set of interrupts by
OR'ing the individual interrupt signals into a summary interrupt
signal routed to a parent interrupt controller, and provides read-
only, 32-bit registers to query the status of individual interrupts.
The status bit for IRQ n is bit (n % 32) within register (n / 32)
of the given combiner. Thus, each combiner can be described as a set
of register offsets and the number of IRQs managed.

an alternate interrupt controller. Introduce acpi_irq_get and use it
to implement ResourceSource/IRQ domain mapping.
The new API is similar to of_irq_get and allows re-initialization
of a platform resource from the ACPI extended IRQ resource, and
provides proper behavior for probe deferral when the domain is not
yet present when called.

ACPI extended IRQ resources may contain a Resource Source field to specify
an alternate interrupt controller, attempting to map them as GSIs is
incorrect, so just disable the platform resource.
Since this field is currently ignored, we make this change conditional
on CONFIG_ACPI_GENERIC_GSI to keep the current behavior on x86 platforms,
in case some existing ACPI tables are using this incorrectly.

This reverts commit 68db9bc814362e7f24371c27d12a4f34477d9356.
Yinghai reported that the following manual hotplug sequence:
# echo 0 > /sys/bus/pci/slots/8/power
# echo 1 > /sys/bus/pci/slots/8/power
worked in v4.9, but fails in v4.10-rc1, and that reverting 68db9bc81436
("PCI: pciehp: Add runtime PM support for PCIe hotplug ports") makes it
work again.
Fixes: 68db9bc81436 ("PCI: pciehp: Add runtime PM support for PCIe hotplug ports")

If blkg_create fails, new_blkg passed as an argument will
be freed by blkg_create, so there is no need to free it again.
