0588b8a034 NFS: switch nfsiod to be an UNBOUND workqueue.
[ Upstream commit bf701b765eaa82dd164d65edc5747ec7288bb5c3 ]

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.

1094bd2eda lockd: don't use interval-based rebinding over TCP
[ Upstream commit 9b82d88d5976e5f2b8015d58913654856576ace5 ]

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.

'snprintf' returns the number of characters which would have been written

Thus, the return value of 'sizeof(buf)' means that the last character

2823b89793 NFSv4.2: condition READDIR's mask for security label based on LSM state
[ Upstream commit 05ad917561fca39a03338cb21fe9622f998b0f9c ]

Currently, the client will always ask for security_labels if the server
returns that it supports that feature regardless of any LSM modules
(such as Selinux) enforcing security policy. This adds performance
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
LSM modules. Thus, prior to using the default bitmask in READDIR,
this patch checks the server's capabilities and then instructs
READDIR to remove FATTR4_WORD2_SECURITY_LABEL from the bitmask.

v5: fixing silly mistakes of the rushed v4
v4: simplifying logic
v3: changing label's initialization per Ondrej's comment
v2: dropping selinux hook and using the sb cap.

[ Upstream commit a0f1ccd96c7049377d892a4299b6d5e47ec9179d ]

Commit 9c80662a74cd ("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).

all the systems from this class used few types of power units, all
equipped with EEPROM device with address space two bytes. Thus, all
these devices have been handled by EEPROM driver "24c02".

There is a new requirement is to support power unit replacement by "off

can be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c02" will not work.

[ Upstream commit 59bbf83835f591b95c3bdd09d900f3584fa227af ]

In omap4_keypad_probe, the patch fix several bugs.

  1) pm_runtime_get_sync will increment pm usage counter even it
     failed. Forgetting to pm_runtime_put_noidle will result in
     reference leak.

  2) In err_unmap, forget to disable runtime of device,
     pm_runtime_enable will increase power disable depth. Thus a
     pairing decrement is needed on the error handling path to keep
     it balanced.

  3) In err_pm_disable, it will call pm_runtime_put_sync twice not
     one time.

To fix this we factor out code reading revision and disabling touchpad, and
drop PM reference once we are done talking to the device.
