ARM virtual counter supports event stream, it can only trigger an event
when the trigger bit (the value of CNTKCTL_EL1.EVNTI) of CNTVCT_EL0 changes,
so the actual period of event stream is 2^(cntkctl_evnti + 1). For example,
when the trigger bit is 0, then virtual counter trigger an event for every
two cycles.
While we're at it, rework the way we compute the trigger bit position
by making it more obvious that when bits [n:n-1] are both set (with n
being the most significant bit), we pick bit (n + 1).

nfsiod is currently a concurrency-managed workqueue (CMWQ).
This means that workitems scheduled to nfsiod on a given CPU are queued
behind all other work items queued on any CMWQ on the same CPU. This
can introduce unexpected latency.
Occaionally nfsiod can even cause excessive latency. If the work item
to complete a CLOSE request calls the final iput() on an inode, the
address_space of that inode will be dismantled. This takes time
proportional to the number of in-memory pages, which on a large host
working on large files (e.g.. 5TB), can be a large number of pages
resulting in a noticable number of seconds.
We can avoid these latency problems by switching nfsiod to WQ_UNBOUND.
This causes each concurrent work item to gets a dedicated thread which
can be scheduled to an idle CPU.
There is precedent for this as several other filesystems use WQ_UNBOUND
workqueue for handling various async events.

NLM uses an interval-based rebinding, i.e. it clears the transport's
binding under certain conditions if more than 60 seconds have elapsed
since the connection was last bound.
This rebinding is not necessary for an autobind RPC client over a
connection-oriented protocol like TCP.
It can also cause problems: it is possible for nlm_bind_host() to clear
XPRT_BOUND whilst a connection worker is in the middle of trying to
reconnect, after it had already been checked in xprt_connect().
When the connection worker notices that XPRT_BOUND has been cleared
under it, in xs_tcp_finish_connecting(), that results in:
xs_tcp_setup_socket: connect returned unhandled error -107
Worse, it's possible that the two can get into lockstep, resulting in
the same behaviour repeated indefinitely, with the above error every
300 seconds, without ever recovering, and the connection never being
established. This has been seen in practice, with a large number of NLM
client tasks, following a server restart.
The existing callers of nlm_bind_host & nlm_rebind_host should not need
to force the rebind, for TCP, so restrict the interval-based rebinding
to UDP only.
For TCP, we will still rebind when needed, e.g. on timeout, and connection
error (including closure), since connection-related errors on an existing
connection, ECONNREFUSED when trying to connect, and rpc_check_timeout(),
already unconditionally clear XPRT_BOUND.
To avoid having to add the fix, and explanation, to both nlm_bind_host()
and nlm_rebind_host(), remove the duplicate code from the former, and
have it call the latter.
Drop the dprintk, which adds no value over a trace.

penalty to the READDIR operation.
Client adjusts superblock's support of the security_label based on
the server's support but also current client's configuration of the

The wmi service available event has been
extended to contain extra 128 bit for new services
to be indicated by firmware.
Currently the presence of any optional TLVs in
the wmi service available event leads to a parsing
error with the below error message:
ath10k_snoc 18800000.wifi: failed to parse svc_avail tlv: -71
The wmi service available event parsing should
not return error for the newly added optional TLV.
Fix this parsing for service available event message.

When an interrupt allocation fails for N interrupts, it is pretty
common for the error handling code to free the same number of interrupts,
no matter how many interrupts have actually been allocated.
This may result in the domain freeing code to be unexpectedly called
for interrupts that have no mapping in that domain. Things end pretty
badly.
Instead, add some checks to irq_domain_free_irqs_hierarchy() to make sure
that thiss does not follow the hierarchy if no mapping exists for a given
interrupt.

Commit 9c80662a74 ("power: supply: axp288_charger: Add special handling
for HP Pavilion x2 10") added special handling for HP Pavilion x2 10
models which use the weird combination of a Type-C connector and the
non Type-C aware AXP288 PMIC.
This special handling was activated by a DMI match a the product-name
of "HP Pavilion x2 Detachable". Recently I've learned that there are
also older "HP Pavilion x2 Detachable" models with an AXP288 PMIC +
a micro-usb connector where we should not activate the special handling
for the Type-C connectors.
Extend the matching to also match on the DMI board-name and match on the
2 boards (one Bay Trail based one Cherry Trail based) of which we are
certain that they use the AXP288 + Type-C connector combination.
Note the DSDT code from these older (AXP288 + micro-USB) models contains
some AML code (which never runs under Linux) which reads the micro-USB
connector id-pin and if it is pulled to ground, which would normally mean
the port is in host mode!, then it sets the input-current-limit to 3A,
it seems HP is using the micro-USB port as a charging only connector
and identifies their own 3A capable charger though this hack which is a
major violation of the USB specs. Note HP also hardcodes a 2A limit
when the id-pin is not pulled to ground, which is also in violation
of the specs.
I've no intention to add support for HP's hack to support 3A charging
on these older models. By making the DMI matches for the Type-C equipped
models workaround more tighter, these older models will be treated just
like any other AXP288 + micro-USB equipped device and the input-current
limit will follow the BC 1.2 spec (using the defacto standard values
there where the BC 1.2 spec defines a range).
