Early alpha processors cannot write a single byte or word; they read 8
bytes, modify the value in registers and write back 8 bytes.
The type blk_status_t is defined as one byte, it is often written
asynchronously by I/O completion routines, this asynchronous modification
can corrupt content of nearby bytes if these nearby bytes can be written
simultaneously by another CPU.
- one example of such corruption is the structure dm_io where
"blk_status_t status" is written by an asynchronous completion routine
and "atomic_t io_count" is modified synchronously
- another example is the structure dm_buffer where "unsigned hold_count"
is modified synchronously from process context and "blk_status_t
write_error" is modified asynchronously from bio completion routine
This patch fixes the bug by changing the type blk_status_t to 32 bits if
we are on Alpha and if we are compiling for a processor that doesn't have
the byte-word-extension.

41f8bba7f555 ("of/pci: Add pci_register_io_range() and
pci_pio_to_address()") added support for PCI I/O space mapped into CPU
physical memory space. With that support, the I/O ranges configured for
PCI/PCIe hosts on some architectures can be mapped to logical PIO and
converted easily between CPU address and the corresponding logical PIO.
Based on this, PCI I/O port space can be accessed via in/out accessors that
use memory read/write.
But on some platforms, there are bus hosts that access I/O port space with
host-local I/O port addresses rather than memory addresses.
Add a more generic I/O mapping method to support those devices. With this
patch, both the CPU addresses and the host-local port can be mapped into
the logical PIO space with different logical/fake PIOs. After this, all
the I/O accesses to either PCI MMIO devices or host-local I/O peripherals
can be unified into the existing I/O accessors defined in asm-generic/io.h
and be redirected to the right device-specific hooks based on the input
logical PIO.

====================
pull-request: bpf-next 2018-03-21
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add a BPF hook for sendmsg and sendfile by reusing the ULP infrastructure
and sockmap. Three helpers are added along with this, bpf_msg_apply_bytes(),
bpf_msg_cork_bytes(), and bpf_msg_pull_data(). The first is used to tell
for how many bytes the verdict should be applied to, the second to tell
that x bytes need to be queued first to retrigger the BPF program for a
verdict, and the third helper is mainly for the sendfile case to pull in
data for making it private for reading and/or writing, from John.
2) Improve address to symbol resolution of user stack traces in BPF stackmap.
Currently, the latter stores the address for each entry in the call trace,
however to map these addresses to user space files, it is necessary to
maintain the mapping from these virtual addresses to symbols in the binary
which is not practical for system-wide profiling. Instead, this option for
the stackmap rather stores the ELF build id and offset for the call trace
entries, from Song.
3) Add support that allows BPF programs attached to perf events to read the
address values recorded with the perf events. They are requested through
PERF_SAMPLE_ADDR via perf_event_open(). Main motivation behind it is to
support building memory or lock access profiling and tracing tools with
the help of BPF, from Teng.
4) Several improvements to the tools/bpf/ Makefiles. The 'make bpf' in the
tools directory does not provide the standard quiet output except for
bpftool and it also does not respect specifying a build output directory.
'make bpf_install' command neither respects specified destination nor
prefix, all from Jiri. In addition, Jakub fixes several other minor issues
in the Makefiles on top of that, e.g. fixing dependency paths, phony
targets and more.
5) Various doc updates e.g. add a comment for BPF fs about reserved names
to make the dentry lookup from there a bit more obvious, and a comment
to the bpf_devel_QA file in order to explain the diff between native
and bpf target clang usage with regards to pointer size, from Quentin
and Daniel.

The v4l2_subdev core s_power op was used for two different things: power on/off
sensors or video decoders/encoders and to put a tuner in standby (and only the
tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner
is accessed.
The danger with calling (s_power, 0) to put a tuner into standby is that it is
usually broadcast for all subdevs. So a video receiver subdev that supports
s_power will also be powered off, and since there is no corresponding (s_power, 1)
they will never be powered on again.
In addition, this is specifically meant for tuners only since they draw the most
current.
This patch adds a new tuner op called 'standby' and replaces all calls to
(core, s_power, 0) by (tuner, standby). This prevents confusion between the two
uses of s_power. Note that there is no overlap: bridge drivers either just want
to put the tuner into standby, or they deal with powering on/off sensors. Never
both.
This also makes it easier to replace s_power for the remaining bridge drivers
with some PM code later.
Whether we want something cleaner for tuners in the future is a separate topic.
There is a lot of legacy code surrounding tuners, and I am very hesitant about
making changes there.

Add a function (as well as a helper macro) to obtain the best size in a
list of device specific sizes. This helps writing drivers as well as
aligns interface behaviour across drivers.
The struct in which this information is contained in is typically specific
to the driver, therefore the existing function v4l2_find_nearest_format()
does not address the need.

All uploaded PM data from non-dom0 CPUs takes the info from vCPU 0 and
changing only the acpi_id. For processors which P-state coordination type
is HW_ALL (0xFD) it is OK to upload bogus P-state dependency information
(_PSD), because Xen will ignore any cpufreq domains created for past CPUs.
Albeit for platforms which expose coordination types as SW_ANY or SW_ALL,
this will have some unintended side effects. Effectively, it will look at
the P-state domain existence and *if it already exists* it will skip the
acpi-cpufreq initialization and thus inherit the policy from the first CPU
in the cpufreq domain. This will finally lead to the original cpu not
changing target freq to P0 other than the first in the domain. Which will
make turbo boost not getting enabled (e.g. for 'performance' governor) for
all cpus.
This patch fixes that, by also evaluating _PSD when we enumerate all ACPI
processors and thus always uploading the correct info to Xen. We export
acpi_processor_get_psd() for that this purpose, but change signature
to not assume an existent of acpi_processor given that ACPI isn't creating
an acpi_processor for non-dom0 CPUs.

Chanwoo writes:
Update extcon for 4.17
Detailed description for this pull request:
1. Add exported extcon function in order to support OF graph binding
- The extcon consumer driver used the "extcon = <&extcon's phandle"
property in device-tree in order to bind between extcon provider
and consumer driver. But, OF graph method is better than 'extcon' property.
So, extcon subsystem adds the following function to support OF graph binding.
: extcon_find_edev_by_node(struct device_node *node)
- Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
and device-tree subsystem. This immutable branch contains the use-case of
OF graph binding for EXTCON_HDMI connector between MHL device driver
and extcon provider driver.
2. Fix minor issues of extcon device drivers
- Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
- Remove workaround code for id pin direction from extcon-inte-int3496.c
because GPIO ACPI library does support it with generic way.
- Set direction and drv flags for V5 boost GPIO because of fixing
the firmware bug.

The target needs to return the lesser of the client's Inbound RDMA
Read Queue Depth (IRD), provided in the connection parameters, and
the local device's Outbound RDMA Read Queue Depth (ORD). The latter
limit is max_qp_init_rd_atom, not max_qp_rd_atom.
The svcrdma_ord value caps the ORD value for iWARP transports, which
do not exchange ORD/IRD values at connection time. Since no other
Linux kernel RDMA-enabled storage target sees fit to provide this
cap, I'm removing it here too.
initiator_depth is a u8, so ensure the computed ORD value does not
overflow that field.

This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.
The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.
Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.

We already have ICMPv6 type/code matches (which can be used to distinguish
different types of MLD packets). Add support for IPv4 IGMP matches in the
same way.

Control module can have multiple instances in a system, each with separate
address space and features. Add base support for these auxiliary instances,
with support for syscon and clock mappings under them.

This patch exposes synproxy information per-conntrack. Moreover, send
sequence adjustment events once server sends us the SYN,ACK packet, so
we can synchronize the sequence adjustment too for packets going as
reply from the server, as part of the synproxy logic.

All existing keys, except the NFT_CT_SRC and NFT_CT_DST are assumed to
have strict datatypes. This is causing problems with sets and

Remove parameter 'family' in nf_conncount_count() and count_tree().
It is because the parameter is not useful after commit 625c556118f3

The NAND chip parameter page is statically allocated within the
nand_chip structure, which reserves a lot of space. Even not ONFI nor
JEDEC chips have it embedded. Also, only a few parameters are actually
read from the parameter page after the detection.
Now that there is a small nand_parameters structure that hold all needed
ONFI parameters, remove the ONFI page from the nand_chip structure by
just allocating it during the identification phase and removing it right
after.

If SET/GET_FEATURES is available (from the parameter page), use a
bitmap to declare what feature is actually supported.
Initialize the bitmap in the core to support timing changes (only
feature used by the core), also add support for Micron specific features
used in Micron initialization code (in the init routine).

The NAND chip parameter page is statically allocated within the
nand_chip structure, which reserves a lot of space. Even not ONFI nor
JEDEC chips have it embedded. Also, only a few parameters are actually
read from the parameter page after the detection.
ONFI-related parameters that will be used outside from the
identification function are stored in a separate onfi_parameters
structure embedded in nand_parameters, this small structure that
already hold generic parameters.
For now, the onfi_parameters structure is allocated statically. However,
after some deep rework in the NAND framework, it will be possible to do
dynamic allocations from the NAND identification phase, and this
strcuture will then be dynamically allocated when needed.

Pull in pending siginfo changes from Eric Biederman as we depend on
the definition of FPE_FLTUNK for cleaning up our floating-point exception
signal delivery (which is currently broken and using FPE_FIXME).

read from the parameter page after the detection.
To prepare to the removal of such huge structure, a small NAND parameter
structure is allocated statically and contains only very few members
that are generic to all chips and actually used elsewhere in the code.
