Turn off the 5V boost regulator on shutdown, there are 3 reasons for
doing this:
1. It drains he battery if left on
2. If left on the device will not charge when plugged into a charger
3. If left on and the powered peripheral attached to a Type-C port is
removed before the next boot, then the Type-C port-controller will
see VBus being present while nothing is attached confusing the
TCPM state-machine.

Switch power_supply_get_battery_info() over to use the generic
fwnode_property_*() property read functions. This is a preparation patch
for adding support for reading properties from other fwnode types such
as swnode properties added by platform code on x86 devices.
Note the parsing of the 2d matrix "ocv-capacity-table-%d" and
"resistance-temp-table" properties is not converted since this depends on
the raw of_get_property() accessor function of which there is no
fwnode_property_*() equivalent AFAICT. This means that these properties
will not be supported in swnodes for now.

If svm_deliver_avic_intr is called just after the target vcpu's AVIC got
inhibited, it might read a stale value of vcpu->arch.apicv_active
which can lead to the target vCPU not noticing the interrupt.
To fix this use load-acquire/store-release so that, if the target vCPU
is IN_GUEST_MODE, we're guaranteed to see a previous disabling of the
AVIC. If AVIC has been disabled in the meanwhile, proceed with the
KVM_REQ_EVENT-based delivery.
Incomplete IPI vmexit has the same races as svm_deliver_avic_intr, and
in fact it can be handled in exactly the same way; the only difference
lies in who has set IRR, whether svm_deliver_interrupt or the processor.
Therefore, svm_complete_interrupt_delivery can be used to fix incomplete
IPI vmexits as well.

The check on the current CPU adds an extra level of indentation to
svm_deliver_avic_intr and conflates documentation on what happens
if the vCPU exits (of interest to svm_deliver_avic_intr) and migrates
(only of interest to avic_ring_doorbell, which calls get/put_cpu()).
Extract the wrmsr to a separate function and rewrite the
comment in svm_deliver_avic_intr().

If i2c_add_adapter() fails to add an I2C adapter found on QCOM CCI
controller, on error path i2c_del_adapter() is still called.
Fortunately there is a sanity check in the I2C core, so the only
visible implication is a printed debug level message:
i2c-core: attempting to delete unregistered adapter [Qualcomm-CCI]
Nevertheless it would be reasonable to correct the probe error path.

drm_gem_cma_mmap() cannot assume every implementation of dma_mmap_wc()
will end up calling remap_pfn_range() (which happens to set the relevant
vma flag, among others), so in order to make sure expectations around
VM_DONTEXPAND are met, let it explicitly set the flag like most other
GEM mmap implementations do.
This avoids repeated warnings on a small minority of systems where the
display is behind an IOMMU, and has a simple driver which does not
override drm_gem_cma_default_funcs. Arm hdlcd is an in-tree affected
driver. Out-of-tree, the Apple DCP driver is affected; this fix is
required for DCP to be mainlined.

Currently, rasdaemon uses the existing tracepoint block_rq_complete
and filters out non-error cases in order to capture block disk errors.
But there are a few problems with this approach:
1. Even kernel trace filter could do the filtering work, there is
still some overhead after we enable this tracepoint.
2. The filter is merely based on errno, which does not align with kernel
logic to check the errors for print_req_error().
3. block_rq_complete only provides dev major and minor to identify
the block device, it is not convenient to use in user-space.
So introduce a new tracepoint block_rq_error just for the error case.
With this patch, rasdaemon could switch to block_rq_error.
Since the new tracepoint has the similar implementation with
block_rq_complete, so move the existing code from TRACE_EVENT
block_rq_complete() into new event class block_rq_completion(). Then add
event for block_rq_complete and block_rq_err respectively from the newly
created event class per the suggestion from Chaitanya Kulkarni.

When a file is opened for writing, the vfs code (do_dentry_open)
calls get_write_access for the inode, thus incrementing the inode's write
count. That writer normally then creates a multi-block reservation for
the inode (i_res) that can be re-used by other writers, which speeds up
writes for applications that stupidly loop on open/write/close.
When the writes are all done, the multi-block reservation should be
deleted when the file is closed by the last "writer."
Commit 0ec9b9ea4f83 broke that concept when it moved the call to
gfs2_rs_delete before the check for FMODE_WRITE. Non-writers have no
business removing the multi-block reservations of writers. In fact, if
someone opens and closes the file for RO while a writer has a
multi-block reservation, the RO closer will delete the reservation
midway through the write, and this results in:
kernel BUG at fs/gfs2/rgrp.c:677! (or thereabouts) which is:
BUG_ON(rs->rs_requested); from function gfs2_rs_deltree.
This patch moves the check back inside the check for FMODE_WRITE.

The IDVS group size feature was missing. It is used on some Bifrost and
Valhall GPUs, and is the last kernel-relevant Bifrost feature we're
missing.
This feature adds an extra IDVS group size field to the JM_CONFIG
register. In kbase, the value is configurable via the device tree; kbase
uses 0xF as a default if no value is specified. Until we find a device
demanding otherwise, let's always set the 0xF default on devices which
support this feature mimicking kbase's behaviour.
Tuning this register slightly improves performance of index-driven
vertex shading. On Mali-G52 (with Mesa), overall glmark2 score is
improved from 1026 to 1037. Geometry-heavy scenes like -bshading are
improved from 1068 to 1098.

Define SoC data structure that includes pci_epc_features, SoC-dependent
callback functions and flags to distinguish the behavior of each SoC.
The callback functions define init() to initialize the controller and
wait() to wait until initialization is completed.
Rename uniphier_pcie_init_ep() to uniphier_pcie_pro5_init_ep() for
initializing PCIe controller implemented in Pro5 SoC. And Pro5 SoC
doesn't have wait() function.

Implement an I2C controller sharing mechanism between the host (kernel)
and PSP co-processor on some platforms equipped with AMD Cezanne SoC.
On these platforms we need to implement "software" i2c arbitration.
Default arbitration owner is PSP and kernel asks for acquire as well
as inform about release of the i2c bus via mailbox mechanism.
+---------+
<- ACQUIRE | |
+---------| CPU |\
| | | \ +----------+ SDA

The solution is similar to i2c-designware-baytrail.c implementation, where
we are using a generic i2c-designware-* driver with a small "wrapper".
In contrary to baytrail semaphore implementation, beside internal
acquire_lock() and release_lock() methods we are also applying quirks to
lock_bus() and unlock_bus() global adapter methods. With this in place
all i2c clients drivers may lock i2c bus for a desired number of i2c
transactions (e.g. write-wait-read) without being aware of that such bus
is shared with another entity.
Modify i2c_dw_probe_lock_support() to select correct semaphore
implementation at runtime, since now we have more than one available.
Configure new matching ACPI ID "AMDI0019" and register
ARBITRATION_SEMAPHORE flag in order to distinguish setup with PSP
arbitration.
Add myself as a reviewer for I2C DesignWare in order to help with reviewing
and testing possible changes touching new i2c-designware-amdpsp.c module.

All accesses to controller's registers should be protected on
probe, disable and xfer paths. This is needed for i2c bus controllers
that are shared with but not controller by kernel.

AMD processors include registers capable of selecting between 2 SMBus

Most important here are a regression fix for brcmfmac USB devices and
an iwlwifi fix for use after free when the firmware was missing. We
have new maintainers for ath9k and wcn36xx as well as ath6kl is now
