The addition of jump label support in dynamic_debug caused an unexpected
warning in exactly one file in the kernel:
drivers/media/dvb-frontends/cxd2841er.c: In function 'cxd2841er_tune_tc':
include/linux/dynamic_debug.h:134:3: error: 'carrier_offset' may be used uninitialized in this function [-Werror=maybe-uninitialized]
__dynamic_dev_dbg(&descriptor, dev, fmt, \
^~~~~~~~~~~~~~~~~
drivers/media/dvb-frontends/cxd2841er.c:3177:11: note: 'carrier_offset' was declared here
int ret, carrier_offset;
^~~~~~~~~~~~~~
The problem seems to be that the compiler gets confused by the extra
conditionals in static_branch_unlikely, to the point where it can no
longer keep track of which branches have already been taken, and it
doesn't realize that this variable is now always initialized when it
gets used.
I have done lots of randconfig kernel builds and could not find any
other file with this behavior, so I assume it's a rare enough glitch
that we don't need to change the jump label support but instead just
work around the warning in the driver.
To achieve that, I'm moving the check for the return value into the
switch() statement, which is an obvious transformation, but is enough to
un-confuse the compiler here. The resulting code is not as nice to
read, but at least we retain the behavior of warning if it gets changed
to actually access an uninitialized carrier offset value in the future.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.
This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.
I noticed two cases where config_enabled() is used against a tristate
option:
- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]
- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]
I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

This clearly had never gotten tested, probably because you need a fairly
minimal configuration in order to disable DEBUG_FS (several other
options select it).
The dummy inline functions that were used for the no-DEBUG_FS case were
missing the argument names in the declarations.

Commit e93762bbf681 ("w1: masters: omap_hdq: add support for 1-wire
mode") added a statement to clear the hdq_irqstatus flags in
hdq_read_byte().
If the hdq reading process is scheduled slowly or interrupts are
disabled for a while the hardware read activity might already be
finished on entry of hdq_read_byte(). And hdq_isr() already has set the
hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the
TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel.
This means there is no need to wait and the hdq_read_byte() can just
read the byte from the hdq controller.
By resetting hdq_irqstatus to 0 the read process is forced to be always
waiting again (because the if statement always succeeds) but the
hardware will not issue another RXCOMPLETE interrupt. This results in a
false timeout.
After such a situation the hdq bus hangs.

Patch series "RapidIO subsystem updates".
This set of patches contains RapidIO subsystem fixes and updates that
have been made since kernel v4.6. The most significant update brings
changes related to the latest revision of RapidIO specification
(rev.3.x) and introduction of next generation of RapidIO switches by IDT
(RXS1632 and RXS2448).
This patch (of 13):
This is RapidIO part of the original patch submitted by Joe Perches.
(see: https://lkml.org/lkml/2016/3/5/19)
Since commit 3cab1e711297 ("lib/vsprintf: refactor duplicate code
to special_hex_number()") %pa uses have been output with a 0x prefix.
These 0x prefixes in the formats are unnecessary.

Add channelized messaging driver to support native RapidIO messaging
exchange between multiple senders/recipients on devices that use kernel
RapidIO subsystem services.
This device driver is the result of collaboration within the RapidIO.org
Software Task Group (STG) between Texas Instruments, Prodrive
Technologies, Nokia Networks, BAE and IDT. Additional input was
received from other members of RapidIO.org.
The objective was to create a character mode driver interface which
exposes messaging capabilities of RapidIO endpoint devices (mports)
directly to applications, in a manner that allows the numerous and
varied RapidIO implementations to interoperate.
This char mode device driver allows user-space applications to setup
messaging communication channels using single shared RapidIO messaging
mailbox.
By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use by
RIONET Ethernet emulation driver).

Some systems are memory constrained but they need to load very large
firmwares. The firmware subsystem allows drivers to request this
firmware be loaded from the filesystem, but this requires that the
entire firmware be loaded into kernel memory first before it's provided
to the driver. This can lead to a situation where we map the firmware
twice, once to load the firmware into kernel memory and once to copy the
firmware into the final resting place.
This creates needless memory pressure and delays loading because we have
to copy from kernel memory to somewhere else. Let's add a
request_firmware_into_buf() API that allows drivers to request firmware
be loaded directly into a pre-allocated buffer. This skips the
intermediate step of allocating a buffer in kernel memory to hold the
firmware image while it's read from the filesystem. It also requires
that drivers know how much memory they'll require before requesting the
firmware and negates any benefits of firmware caching because the
firmware layer doesn't manage the buffer lifetime.
For a 16MB buffer, about half the time is spent performing a memcpy from
the buffer to the final resting place. I see loading times go from
0.081171 seconds to 0.047696 seconds after applying this patch. Plus
the vmalloc pressure is reduced.
This is based on a patch from Vikram Mulukutla on codeaurora.org:
https://www.codeaurora.org/cgit/quic/la/kernel/msm-3.18/commit/drivers/base/firmware_class.c?h=rel/msm-3.18&id=0a328c5f6cd999f5c591f172216835636f39bcb5

Some low memory systems with complex peripherals cannot afford to have
the relatively large firmware images taking up valuable memory during
suspend and resume. Change the internal implementation of
firmware_class to disallow caching based on a configurable option. In
the near future, variants of request_firmware will take advantage of
this feature.

adds support to the request firmware API to load the firmware directly

alleviating memory pressure during firmware loading. The drawback is
that we can't use the firmware caching feature because the memory for
the firmware cache is not managed by the firmware layer.
This patch (of 3):
We use similar structured code to read and write the kmapped firmware
pages. The only difference is read copies from the kmap region and
write copies to it. Consolidate this into one function to reduce
duplication.

__init_refok was used 46 times against 82 for __ref.

'This pull request contains only one notable change:
- Addition of the MTK NAND controller driver
And a bunch of specific NAND driver improvements/fixes. Here are the
changes that are worth mentioning:
- A few fixes/improvements for the xway NAND controller driver
- A few fixes for the sunxi NAND controller driver
- Support for DMA in the sunxi NAND driver
- Support for the sunxi NAND controller IP embedded in A23/A33 SoCs
- Addition for bitflips detection in erased pages to the brcmnand driver
- Support for new brcmnand IPs
- Update of the OMAP-GPMC binding to support DMA channel description'
In addition, some small fixes around error handling, etc., as well
as one long-standing corner case issue (2.6.20, I think?) with
writing 1 byte less than a page.
NOR:
- rework some error handling on reads and writes, so we can better
handle (for instance) SPI controllers which have limitations on
their maximum transfer size

Pull KVM updates from Paolo Bonzini:
- ARM: GICv3 ITS emulation and various fixes. Removal of the
old VGIC implementation.
- s390: support for trapping software breakpoints, nested
virtualization (vSIE), the STHYI opcode, initial extensions
for CPU model support.
- MIPS: support for MIPS64 hosts (32-bit guests only) and lots
of cleanups, preliminary to this and the upcoming support for
hardware virtualization extensions.
- x86: support for execute-only mappings in nested EPT; reduced
vmexit latency for TSC deadline timer (by about 30%) on Intel
hosts; support for more than 255 vCPUs.
- PPC: bugfixes.

This commit fixes both local (in stmmac_axi_setup) and global
(plat->phy_node) device_node for this issue, and using the
correct device node when tries to put node at stmmac_probe_config_dt
for error path.
