[ Upstream commit fa4e7fc1386078edcfddd8848cb0374f4af74fe7 ]
xsdfec_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.CC: Derek Kiernan

commit 529244bd1afc102ab164429d338d310d5d65e60d upstream.
Doing an add/remove/add on a SCSI device in an enclosure leads to an oops
caused by poisoned values in the enclosure device list pointers. The
reason is because we are keeping the enclosure device across the enclosed
device add/remove/add but the current code is doing a
device_add/device_del/device_add on it. This is the wrong thing to do in
sysfs, so fix it by not doing a device_del on the enclosure device simply
because of a hot remove of the drive in the slot.[mkp: added missing email addresses]
Fixes: 43d8eb9cfd0a ("[SCSI] ses: add support for enclosure component hot removal")

[ Upstream commit 018e0e3594f7dcd029d258e368c485e742fa9cdb ]
In case a user submits a CS, and the submission fails, and the user doesn't
check the return value and instead use the error return value as a valid
sequence number of a CS and ask to wait on it, the driver will print an
error and return an error code for that wait.The real problem happens if now the user ignores the error of the wait, and
try to wait again and again. This can lead to a flood of error messages
from the driver and even soft lockup event.Signed-off-by: Oded Gabbay

[ Upstream commit 71c5e55e7c077fa17c42fbda91a8d14322825c44 ]
Reduce context close time by skipping the VA block free list update in
order to avoid hard reset with open contexts.
Reset with open contexts can potentially lead to a kernel crash as the
generic pool of the MMU hops is destroyed while it is not empty because
some unmap operations are not done.

commit a58d37bce0d21cf7fbd589384c619e465ef2f927 upstream.
If an ocxl device is unbound through sysfs at the same time its AFU is
being opened by a user process, the open code may dereference freed
stuctures, which can lead to kernel oops messages. You'd have to hit a
tiny time window, but it's possible. It's fairly easy to test by
making the time window bigger artificially.Fix it with a combination of 2 changes:
- when an AFU device is found in the IDR by looking for the device
minor number, we should hold a reference on the device until after
the context is allocated. A reference on the AFU structure is kept
when the context is allocated, so we can release the reference on
the device after the context allocation.
- with the fix above, there's still another even tinier window,
between the time the AFU device is found in the IDR and the
reference on the device is taken. We can fix this one by removing
the IDR entry earlier, when the device setup is removed, instead
of waiting for the 'release' device callback. With proper locking
around the IDR.Fixes: 75ca758adbaf ("ocxl: Create a clear delineation between ocxl backend & frontend")

Pull powerpc updates from Michael Ellerman:
"This is a bit late, partly due to me travelling, and partly due to a
power outage knocking out some of my test systems *while* I was
travelling.- Initial support for running on a system with an Ultravisor, which
is software that runs below the hypervisor and protects guests
against some attacks by the hypervisor.- Support for building the kernel to run as a "Secure Virtual
Machine", ie. as a guest capable of running on a system with an
Ultravisor.- Some changes to our DMA code on bare metal, to allow devices with
medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of
DMA space.- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas
macros, both to make it more readable and also enable some future
optimisations.As well as many cleanups and other minor features & fixups.

Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name- update following drivers and their DT bindings to use the new LED
registration API:- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-bltOther LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug- ledtrig-gpio:
- GPIO 0 is validDrop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return- leds-pwm, leds-is31fl32xx:
- use struct_size() helper- leds-lm3697, leds-lm36274, leds-lm3532:
- switch to use fwnode_property_count_uXX()- leds-lm3532:
- fix brightness control for i2c mode
- change the define for the fs current register
- fixes for the driver for stability

- fix optional led-max-microamp prop error handling- leds-max77650:
- add of_node_put() before return
- add MODULE_ALIAS()
- Switch to fwnode property API- leds-as3645a:
- fix misuse of strlcpy- leds-netxbig:
- add of_node_put() in netxbig_leds_get_of_pdata()
- remove legacy board-file support- leds-is31fl319x:
- simplify getting the adapter of a client- leds-ti-lmu-common:
- fix coccinelle issue
- move static keyword to the front of declaration- leds-syscon:
- use resource managed variant of device register- leds-ktd2692:
- fix a typo in the name of a constant- leds-lp5562:
- allow firmware files up to the maximum length- leds-an30259a:

To allow the user to use a custom file for the HWMON lm-sensors library
per card type, the driver needs to register the HWMON sensors with the
specific card type name.The card name is supplied by the F/W running on the device. If the F/W is
old and doesn't supply a card name, a default card name is displayed as
the sensors group name.Signed-off-by: Oded Gabbay

Add a new opcode to INFO IOCTL to retrieve aggregate H/W events. i.e. the
events counters are NOT cleared upon device reset, but count from the

Users and sysadmins usually want to know what is the device utilization as
a level 0 indication if they are efficiently using the device.Add a new opcode to the INFO IOCTL that will return the device utilization
over the last period of 100-1000ms. The return value is 0-100,
representing as percentage the total utilization rate.Signed-off-by: Oded Gabbay

The Coresight timestamp is enabled for a specific debug session using
the HL_DEBUG_OP_TIMESTAMP opcode of the debug IOCTL.
In order to have a perpetual timestamp that would be comparable between
various debug sessions, this patch moves the timestamp enablement to be
part of the HW initialization.
The HL_DEBUG_OP_TIMESTAMP opcode turns to be deprecated and shouldn't be
used. Old user-space that will call it won't see any change in the
behavior of the debug session.Signed-off-by: Tomer Tayar
