During device memory memset, the driver allocates and use a CB (command
buffer). To reuse existing code, it keeps a pointer to the CB in two
variables, user_cb and patched_cb. Therefore, there is no need to "put"
both the user_cb and patched_cb, as it will cause an underflow of the
refcnt of the CB.

During hard reset we must not write to the device.
Hence avoid halting CoreSight during user context close if it is done
during hard reset.
In addition, we must not re-enable clock gating afterwards as it was
deliberately disabled in the beginning of the hard reset flow.

The driver must halt the engines before doing hard-reset, otherwise the
device can go into undefined state. There is a place where the driver
didn't do that and this patch fixes it.

Pull i2c updates from Wolfram Sang:
"i2c core:
- huge improvements and refactorizations of the Linux I2C
documentation (lots of thanks to Luca for doing it and Jean for the
careful review)
- subsystem wide API conversion to i2c_new_client_device()
- remove obsolete parport-light driver
- smaller core updates (removal of 'extern', enabling more compile
testing, use more helper macros)
- and quite a bunch of driver updates (new IDs, simplifications,
better PM, support of atomic transfers and other improvements)
i2c-mux:
- The main feature is the idle-state rework of the pca954x driver
from Biwen Li
at24 driver:
- minor maintenance: update the license tag, sort headers
- move support for the write-protect pin into nvmem core
- add a reference to the new wp-gpios property in nvmem to at25
bindings
- add support for regulator and pm_runtime control"

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.

The second arg of xsdfec_set_order() is a 'void __user *'
and this pointer is then used in get_user() which expect
a __user pointer.
But get_user() can't be used with a void pointer, it a
pointer to the effective type. This is done here by casting
the argument to a pointer to the effective type but the
__user is missing in the cast.
Fix this by adding the missing __user in the cast.

Some users prefer kdump tools to generate guest kernel dumpfile,
at the same time, need a out-of-band kernel panic event.
Currently if booting guest kernel with 'crash_kexec_post_notifiers',
QEMU will receive PVPANIC_PANICKED event and stop VM. If booting
guest kernel without 'crash_kexec_post_notifiers', guest will not
call notifier chain.
Add PVPANIC_CRASH_LOADED bit for pvpanic event, it means that guest
kernel actually hit a kernel panic, but the guest kernel wants to
handle by itself.

Right now several architectures allow their set_memory_*() family of
functions to fail, but callers may not be checking the return values.
If set_memory_*() returns with an error, call-site assumptions may be
infact wrong to assume that it would either succeed or not succeed at
all. Ideally, the failure of set_memory_*() should be passed up the call
stack, and callers should examine the failure and deal with it.
Need to fix the callers and add the __must_check attribute. They also
may not provide any level of atomicity, in the sense that the memory
protections may be left incomplete on failure. This issue likely has a
few steps on effects architectures:
1) Have all callers of set_memory_*() helpers check the return value.
2) Add __must_check to all set_memory_*() helpers so that new uses do
not ignore the return value.
3) Add atomicity to the calls so that the memory protections aren't
left in a partial state.
This series is part of step 1. Make sram driver check the return value
of set_memory_*().

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.

Two weeks worth of accumulated fixes.
A fix for a performance regression seen on PowerVM LPARs using dedicated CPUs,
caused by our vcpu_is_preempted() returning true even for idle CPUs.
One of the ultravisor support patches broke KVM on big endian hosts in v5.4.
Our KUAP (Kernel User Access Prevention) code missed allowing access in
__clear_user(), which could lead to an oops or erroneous SEGV when triggered via
PTRACE_GETREGSET.
Two fixes for the ocxl driver, an open/remove race, and a memory leak in an
error path.
A handful of other small fixes.

Merge tag 'powerpc-5.5-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
"Two weeks worth of accumulated fixes:
- A fix for a performance regression seen on PowerVM LPARs using
dedicated CPUs, caused by our vcpu_is_preempted() returning true
even for idle CPUs.
- One of the ultravisor support patches broke KVM on big endian hosts
in v5.4.
- Our KUAP (Kernel User Access Prevention) code missed allowing
access in __clear_user(), which could lead to an oops or erroneous
SEGV when triggered via PTRACE_GETREGSET.
- Two fixes for the ocxl driver, an open/remove race, and a memory
leak in an error path.
- A handful of other small fixes.
Thanks to: Andrew Donnellan, Christian Zigotzky, Christophe Leroy,
