Enable non-blocking receive for drivers on mei bus, this allows checking
for data availability by mei client drivers. This is most effective for
fixed address clients, that lacks flow control.
This function adds new API function mei_cldev_recv_nonblock(), it

The vme_driver structure currently has a "shutdown" entry. This entry is
never used, it lacks the correct parameter (it should be providing a
pointer to the relevant vme_dev struct to even *look* usable), the VME
subsystem currently doesn't provide support for shutdown functions and no
in-tree drivers use it (hardly surprising, given it'd never be called).
Remove the entry from vme_driver to avoid confusion.

This interface was designed for streaming, but write_init's buf
argument has an unclear purpose. Define it to be the first bytes
of the bitstream. Each driver gets to set how many bytes (at most)
it wants to see. Short bitstreams will be passed through as-is, while
long ones will be truncated.
The intent is to allow drivers to peek at the header before the transfer
actually starts.

Limit the number of kmemleak false positives by including
.data.ro_after_init in memory scanning. To achieve this we need to add
symbols for start and end of the section to the linker scripts.
The problem was been uncovered by commit 56989f6d8568 ("genetlink: mark
families as __ro_after_init").

This reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path").
The reverted commit changes existing behavior on which many ARM boards
rely. Many ARM small-board-computers, like e.g. the Raspberry Pi have
both a video output and a serial console. Depending on whether the user
is using the device as a more regular computer; or as a headless device
we need to have the console on either one or the other.
Many users rely on the kernel behavior of the console being present on
both outputs, before the reverted commit the console setup with no
console= kernel arguments on an ARM board which sets stdout-path in dt
would look like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
tty0 -WU (E p ) 4:1
Where as after the reverted commit, it looks like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
This commit reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path") restoring the original
behavior.

Christian Borntraeger reports:
With commit 8ea1d2a1985a ("mm, frontswap: convert frontswap_enabled to
static key") kmemleak complains about a memory leak in swapon
unreferenced object 0x3e09ba56000 (size 32112640):
comm "swapon", pid 7852, jiffies 4294968787 (age 1490.770s)
hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:
__vmalloc_node_range+0x194/0x2d8
vzalloc+0x58/0x68
SyS_swapon+0xd60/0x12f8
system_call+0xd6/0x270
Turns out kmemleak is right. We now allocate the frontswap map
depending on the kernel config (and no longer on the enablement)
swapfile.c:
[...]
if (IS_ENABLED(CONFIG_FRONTSWAP))
frontswap_map = vzalloc(BITS_TO_LONGS(maxpages) * sizeof(long));
but later on this is passed along
--> enable_swap_info(p, prio, swap_map, cluster_info, frontswap_map);
and ignored if frontswap is disabled
--> frontswap_init(p->type, frontswap_map);
static inline void frontswap_init(unsigned type, unsigned long *map)
{
if (frontswap_enabled())
__frontswap_init(type, map);
}
Thing is, that frontswap map is never freed.
The leakage is relatively not that bad, because swapon is an infrequent
and privileged operation. However, if the first frontswap backend is
registered after a swap type has been already enabled, it will WARN_ON
in frontswap_register_ops() and frontswap will not be available for the
swap type.
Fix this by making sure the map is assigned by frontswap_init() as long
as CONFIG_FRONTSWAP is enabled.

This framework adds API functions for enabling/
disabling FPGA bridges under kernel control.
This allows the Linux kernel to disable FPGA bridges
during FPGA reprogramming and to enable FPGA bridges
when FPGA reprogramming is done. This framework is
be manufacturer-agnostic, allowing it to be used in
interfaces that use the FPGA Manager Framework to
reprogram FPGA's.
The functions are:
* of_fpga_bridge_get
* fpga_bridge_put
Get/put an exclusive reference to a FPGA bridge.
* fpga_bridge_enable
* fpga_bridge_disable
Enable/Disable traffic through a bridge.
* fpga_bridge_register
* fpga_bridge_unregister
Register/unregister a device-specific low level FPGA
Bridge driver.
Get an exclusive reference to a bridge and add it to a list:
* fpga_bridge_get_to_list
To enable/disable/put a set of bridges that are on a list:
* fpga_bridges_enable
* fpga_bridges_disable
* fpga_bridges_put

This patch adds a minor change in the FPGA Manager API
to hold information that is specific to an FPGA image
file. This change is expected to bring little, if any,
pain. The socfpga and zynq drivers are fixed up in
this patch.
An FPGA image file will have particulars that affect how the
image is programmed to the FPGA. One example is that
current 'flags' currently has one bit which shows whether the
FPGA image was built for full reconfiguration or partial
reconfiguration. Another example is timeout values for
enabling or disabling the bridges in the FPGA. As the
complexity of the FPGA design increases, the bridges in the
FPGA may take longer times to enable or disable.
This patch adds a new 'struct fpga_image_info', moves the
current 'u32 flags' to it. Two other image-specific u32's
are added for the bridge enable/disable timeouts. The FPGA
Manager API functions are changed, replacing the 'u32 flag'
parameter with a pointer to struct fpga_image_info.
Subsequent patches fix the existing low level FPGA manager
drivers.

This patch add of overlay notifications.
When DT overlays are being added, some drivers/subsystems
need to see device tree overlays before the changes go into
the live tree.
This is distinct from reconfig notifiers that are
post-apply or post-remove and which issue very granular
notifications without providing access to the context
of a whole overlay.
The following 4 notificatons are issued:
OF_OVERLAY_PRE_APPLY
OF_OVERLAY_POST_APPLY
OF_OVERLAY_PRE_REMOVE
OF_OVERLAY_POST_REMOVE
In the case of pre-apply notification, if the notifier
returns error, the overlay will be rejected.
This patch exports two functions for registering/unregistering
notifications:
of_overlay_notifier_register(struct notifier_block *nb)
of_overlay_notifier_unregister(struct notifier_block *nb)
The of_mutex is held during these notifications. The
notification data includes pointers to the overlay target
and the overlay:
struct of_overlay_notify_data {
struct device_node *overlay;
struct device_node *target;
};

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the bitmap like
events do") added a couple of this_cpu_read calls to the ftrace code.
On x86 this is not a problem, since it has single instructions to read
percpu data. Other architectures which use the generic variant now
have additional preempt_disable and preempt_enable calls in the core
ftrace code. This may lead to recursive calls and in result to a dead
machine, e.g. if preemption and debugging options are enabled.
To fix this use the notrace variant of preempt_disable and
preempt_enable within the generic percpu code.

Currently we dropped freeze protection of aio writes just after IO was
submitted. Thus aio write could be in flight while the filesystem was
frozen and that could result in unexpected situation like aio completion
wanting to convert extent type on frozen filesystem. Testcase from
Dmitry triggering this is like:
for ((i=0;i<60;i++));do fsfreeze -f /mnt ;sleep 1;fsfreeze -u /mnt;done &
fio --bs=4k --ioengine=libaio --iodepth=128 --size=1g --direct=1 \
--runtime=60 --filename=/mnt/file --name=rand-write --rw=randwrite
Fix the problem by dropping freeze protection only once IO is completed
in aio_complete().

When vxlan device is closed vxlan socket is freed. This
operation can race with vxlan-xmit function which
dereferences vxlan socket. Following patch uses RCU

Currently interrupt test that is part of ethtool selftest runs the
check over all interrupt vectors of the device.
In mlx4_en package part of interrupt vectors are uninitialized since
mlx4_ib doesn't exist. This causes NOP FW command to time out.
Change logic to test current port interrupt vectors only.

====================
Just two fixes:
* a fix to process all events while suspending, so any

suspended
* small markup fixes for the sphinx documentation conversion

This reverts commit e3f74b841d48
("hv_netvsc: report vmbus name in ethtool")'
because of problem introduced by commit f9a56e5d6a0ba
("Drivers: hv: make VMBus bus ids persistent").
This changed the format of the vmbus name and this new format is too
long to fit in the bus_info field of ethtool.

In case that the kernel PCI error handlers are not called, we will
trigger our own recovery flow.
The health work will give priority to the kernel pci error handlers to
recover the PCI by waiting for a small period, if the pci error handlers
are not triggered the manual recovery flow will be executed.
We don't save pci state in case of manual recovery because it will ruin the
pci configuration space and we will lose dma sync.

Currently there is a race between the health care work and the kernel
pci error handlers because both of them detect the error, the first one
to be called will do the error handling.
There is a chance that health care will disable the pci after resuming
pci slot.
Also create a separate WQ because now we will have two types of health
works, one for the error detection and one for the recovery.
