Introduce NETIF_F_GRO_HW feature flag for NICs that support hardware
GRO. With this flag, we can now independently turn on or off hardware
GRO when GRO is on. Previously, drivers were using NETIF_F_GRO to
control hardware GRO and so it cannot be independently turned on or
off without affecting GRO.
Hardware GRO (just like GRO) guarantees that packets can be re-segmented
by TSO/GSO to reconstruct the original packet stream. Logically,
GRO_HW should depend on GRO since it a subset, but we will let
individual drivers enforce this dependency as they see fit.
Since NETIF_F_GRO is not propagated between upper and lower devices,
NETIF_F_GRO_HW should follow suit since it is a subset of GRO. In other
words, a lower device can independent have GRO/GRO_HW enabled or disabled
and no feature propagation is required. This will preserve the current
GRO behavior. This can be changed later if we decide to propagate GRO/
GRO_HW/RXCSUM from upper to lower devices.

This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX.
This 18 bit field, when present, carries the index of the DVB-S2 physical
layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
There is no explicit signalling method to convey scrambling sequence index
to the receiver. If S2 satellite delivery system descriptor is available
it can be used to read the scrambling sequence index (EN 300 468 table 41).
By default, gold scrambling sequence index 0 is used. The valid scrambling
sequence index range is from 0 to 262142.
Increase the DVB API version in order userspace to be aware of the changes.

One should also ensure that a unique name is used. Generic names such as

Disabling IRQ #51
On a multi-UART max310x, each UART has its own interrupt status register
which automatically de-asserts the IRQ line upon read. (There are also
top-level IRQ indicator registers which are not clear-on-read, but they
are not relevant here.) It was quite possible to receive a pending IRQ
for, e.g., UART0, enter the threaded IRQ handler, clear the ISR for
UART0 which de-asserts the IRQ line, and then race with another event on
the same chip, but a different UART channel. That resulted in another
edge on the shared-within-the-chip IRQ line which got intercepted by the
kernel.
That all led to an edge-level interrupt which was not being handled by
anybody because our threaded handler hasn't finished yet. As the chip
actually uses *level* triggered IRQs, let's convert the example DT
bindings to these.

SIOX is a bus system invented at Eckelmann AG to control their building
management and refrigeration systems. Traditionally the bus was
implemented on custom microcontrollers, today Linux based machines are
in use, too.
The topology on a SIOX bus looks as follows:
,------->--DCLK-->---------------+----------------------.
^ v v
,--------. ,----------------------. ,------
| | | ,--------------. | |
| |--->--DOUT-->---|->-|shift register|->-|--->---|
| | | `--------------' | |
| master | | device | | device
| | | ,--------------. | |
| |---<--DIN---<---|-<-|shift register|-<-|---<---|
| | | `--------------' | |
`--------' `----------------------' `------
v ^ ^
`----------DLD-------------------+----------------------'
There are two control lines (DCLK and DLD) driven from the bus master to
all devices in parallel and two daisy chained data lines, one for input
and one for output. DCLK is the clock to shift both chains by a single
bit. On an edge of DLD the devices latch both their input and output
shift registers.
This patch adds a framework for this bus type.

The semantics for lirc IR transmit with raw IR is that the write call
should block until the IR is transmitted. Some drivers have no idea
when this actually is (e.g. mceusb), so there is a wait.
This is useful for userspace, as it might want to send a IR button press,
a gap of a predefined number of milliseconds, and then send a repeat
message.
It turns out that for transmitting scancodes this feature is even more
useful, as user space has no idea how long the IR is. So, maintain
the existing semantics for IR scancode transmit.

Certain EEPROMS have a size that is larger than the number of address
bytes would allow, and store the MSB of the address in bit 3 of the
instruction byte.
This can be described in platform data using EE_INSTR_BIT3_IS_ADDR, or
in DT using the obsolete legacy "at25,addr-mode" property.
But currently there exists no non-deprecated way to describe this in DT.
Hence extend the existing "address-width" DT property to allow
specifying 9 address bits, and enable support for that in the driver.
This has been tested with a Microchip 25LC040A.

The builtin ima_appraise_tcb policy, which is specified on the boot
command line, can be replaced with a custom policy, normally early in
the boot process. Custom policies can be more restrictive in some ways,
like requiring file signatures, but can be less restrictive in other
ways, like not appraising mutable files. With a less restrictive policy
in place, files in the builtin policy might not be hashed and labeled
with a security.ima hash. On reboot, files which should be labeled in
the ima_appraise_tcb are not labeled, possibly preventing the system
from booting properly.
To resolve this problem, this patch extends the existing IMA policy
actions "measure", "dont_measure", "appraise", "dont_appraise", and
"audit" with "hash" and "dont_hash". The new "hash" action will write
the file hash as security.ima, but without requiring the file to be
appraised as well.
For example, the builtin ima_appraise_tcb policy includes the rule,
"appraise fowner=0". Adding the "hash fowner=0" rule to a custom
policy, will cause the needed file hashes to be calculated and written
as security.ima xattrs.

In Linux build system convention, pre-generated files are version-
controlled with a "_shipped" suffix. During the kernel building,
they are simply shipped (copied) removing the suffix.
This approach can reduce external tool dependency for the kernel build,
but it is tedious to manually regenerate such artifacts from developers'
point of view. (We need to do "make REGENERATE_PARSERS=1" every time
we touch real source files such as *.l, *.y)
Some months ago, I sent out RFC patches to run flex, bison, and gperf
during the build.
In the review and test, Linus noticed gperf-3.1 had changed the lookup
function prototype. Then, the use of gperf in kernel was entirely
removed by commit bb3290d916 ("Remove gperf usage from toolchain").
This time, I tested several versions of flex and bison, and I was not
hit by any compatibility issue except a flaw in flex-2.6.3; if you
generate lexer for dtc and genksyms with flex-2.6.3, you will see
"yywrap redefined" warning. This was not intentional, but a bug,
fixed by flex-2.6.4. Otherwise, both flex and bison look fairly
stable for a long time.
This commit prepares some build rules to remove the _shipped files.
Also, document minimal requirement for flex and bison.
Rationale for the minimal version:
The -Wmissing-prototypes option of GCC warns "no previous prototype"
for lexers generated by flex-2.5.34 or older, so I chose 2.5.35 as the
required version for flex. Flex-2.5.35 was released in 2008. Bison
looks more stable. I did not see any problem with bison-2.0, released
in 2004. I did not test bison-1.x, but bison-2.0 should be old enough.

2.5.35

Pull arm64 fixes from Will Deacon:
"There are some significant fixes in here for FP state corruption,
hardware access/dirty PTE corruption and an erratum workaround for the
Falkor CPU.
I'm hoping that things finally settle down now, but never say never...
Summary:
- Fix FPSIMD context switch regression introduced in -rc2
- Fix ABI break with SVE CPUID register reporting
- Fix use of uninitialised variable
- Fixes to hardware access/dirty management and sanity checking
- CPU erratum workaround for Falkor CPUs
- Fix reporting of writeable+executable mappings
- Fix signal reporting for RAS errors"

Pull locking fixes from Ingo Molnar:
"Misc fixes:
- Fix a S390 boot hang that was caused by the lock-break logic.
Remove lock-break to begin with, as review suggested it was
unreasonably fragile and our confidence in its continued good
health is lower than our confidence in its removal.
- Remove the lockdep cross-release checking code for now, because of
unresolved false positive warnings. This should make lockdep work
well everywhere again.
- Get rid of the final (and single) ACCESS_ONCE() straggler and
remove the API from v4.15.
- Fix a liblockdep build warning"
* 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
tools/lib/lockdep: Add missing declaration of 'pr_cont()'
checkpatch: Remove ACCESS_ONCE() warning
compiler.h: Remove ACCESS_ONCE()
tools/include: Remove ACCESS_ONCE()
tools/perf: Convert ACCESS_ONCE() to READ_ONCE()
locking/lockdep: Remove the cross-release locking checks
locking/core: Remove break_lock field when CONFIG_GENERIC_LOCKBREAK=y
locking/core: Fix deadlock during boot on systems with GENERIC_LOCKBREAK
Update the device tree binding documentation for the Marvell EBU UART,
in order to allow describing the extended UART IP block, in addition to
the already supported standard UART IP. This requires adding a new
compatible string, the introduction of a clocks property, and extensions
to the interrupts property.

Add "sff,sff" for SFF module support with SFP. These have a different
phys_id value, and also have the present and rate select signals omitted
compared with their socketed counter-parts.
