After commit 47c950d102 ("pinctrl: cherryview: Do not add all
southwest and north GPIOs to IRQ domain") the driver does not add all
GPIOs to the irqdomain. The reason for that is that those GPIOs cannot
generate IRQs at all, only GPEs (General Purpose Events). This causes
Linux virtual IRQ numbering to change.
However, it seems some CYAN Chromebooks, including Acer Chromebook
hardcodes these Linux IRQ numbers in the ACPI tables of the machine.
Since the numbering is different now, the IRQ meant for keyboard does
not match the Linux virtual IRQ number anymore making the keyboard
non-functional.
Work this around by adding special quirk just for these machines where
we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell
based machines will not be affected by the change.

The schemata lock is released before freeing the resource's temporary
tmp_cbms allocation. That's racy versus another write which allocates and
uses new temporary storage, resulting in memory leaks, freeing in use
memory, double a free or any combination of those.
Move the unlock after the release code.

This fixes Continuous Availability when errors during
file reopen are encountered.
cifs_user_readv and cifs_user_writev would wait for ever if
results of cifs_reopen_file are not stored and for later inspection.
In fact, results are checked and, in case of errors, a chain
of function calls leading to reads and writes to be scheduled in
a separate thread is skipped.
These threads will wake up the corresponding waiters once reads
and writes are done.
However, given the return value is not stored, when rc is checked
for errors a previous one (always zero) is inspected instead.
This leads to pending reads/writes added to the list, making
cifs_user_readv and cifs_user_writev wait for ever.

STATUS_BAD_NETWORK_NAME can be received during node failover,
causing the flag to be set and making the reconnect thread
always unsuccessful, thereafter.
Once the only place where it is set is removed, the remaining
bits are rendered moot.
Removing it does not prevent "mount" from failing when a non

What happens when the share really ceases to exist while the
share is mounted is undefined now as much as it was before.

Commit 1a967d6c9b ("correctly to
anonymous authentication for the NTLM(v2) authentication") introduces
a regression in handling errors related to attempting a guest
connection to a Windows share which requires authentication. This
should result in a permission denied error but actually causes the
kernel module to enter a never-ending loop trying to follow a DFS
referal which doesn't exist.
The base cause of this is the failure now occurs later in the process
during tree connect and not at the session setup setup and all errors
in tree connect are interpreted as needing to follow the DFS paths
which isn't in this case correct. So, check the returned error against
EACCES and fail if this is returned error.
Feedback from Aurelien:
PS> net user guest /activate:no
PS> mkdir C:\guestshare
PS> icacls C:\guestshare /grant 'Everyone:(OI)(CI)F'
PS> new-smbshare -name guestshare -path C:\guestshare -fullaccess Everyone
I've tested v3.10, v4.4, master, master+your patch using default options
(empty or no user "NU") and user=abc (U).
NT_LOGON_FAILURE in session setup: LF
This is what you seem to have in 3.10.
NT_ACCESS_DENIED in tree connect to the share: AD
This is what you get before your infinite loop.
| NU U
--------------------------------
3.10 | LF LF
4.4 | LF LF
master | AD LF
master+patch | AD LF
No infinite DFS loop :(
All these issues result in mount failing very fast with permission denied.
I guess it could be from either the Windows version or the share/folder
ACL. A deeper analysis of the packets might reveal more.
In any case I did not notice any issues for on a basic DFS setup with
the patch so I don't think it introduced any regressions, which is
probably all that matters. It still bothers me a little I couldn't hit
the bug.
I've included kernel output w/ debugging output and network capture of
my tests if anyone want to have a look at it. (master+patch = ml-guestfix).

ftgmac100: Rework batch 3 - TX path
This is version 2 of the third batch of updates to
the ftgmac100 driver.
This one tackles the TX path of the driver. This provides the
bulk of the performance improvements by adding support for
fragmented sends along with a bunch of cleanups.
Version 2 fixes a patch splitting mistake and uses
eth_skb_pad() (which uses skb_put_padto) to pad ethernet
frames rather than skb_padto(), thus removing the need to
also pad the packet headlen in a couple of places.
Subsequent batches will add various features (ethtool functions,
vlan offlan, ...) and cleanups.

We have a private lock which isn't terribly useful, and we maintain
a "tx_pending" counter for information that's already available
via a trivial arithmetic operation. Then we unconditionaly wake
the queue even when not stopped. Finally our code in tx isn't
really safe vs. a concurrent reclaim. The aspeed chips aren't SMP
today but I prefer the code being right and future proof.
So rip that out and replace it with more "standard" queue handling,
currently with a threshold of 1 queue element, which will be
increased when we implement fragmented sends.

The retry queue is intended to provide a temporary buffer in the case
of transient errors when communicating with auditd, it is not meant
as a long life queue, that functionality is provided by the hold
queue.
This patch fixes a problem identified by Seth where the retry queue
could grow uncontrollably if an auditd instance did not connect to
the kernel to drain the queues. This commit fixes this by doing the
following:
* Make sure we always call auditd_reset() if we decide the connection
with audit is really dead. There were some cases in
kauditd_hold_skb() where we did not reset the connection, this patch
relocates the reset calls to kauditd_thread() so all the error
conditions are caught and the connection reset. As a side effect,
this means we could move auditd_reset() and get rid of the forward
definition at the top of kernel/audit.c.
* We never checked the status of the auditd connection when
processing the main audit queue which meant that the retry queue
could grow unchecked. This patch adds a call to auditd_reset()
after the main queue has been processed if auditd is not connected,
the auditd_reset() call will make sure the retry and hold queues are
correctly managed/flushed so that the retry queue remains reasonable.

Jake fixes up error messages to better clarify to the user when adding a
invalid flow type. Updates the driver to look up the MAC address from
eth_get_platform_mac_address() first before checking what the firmware
provides. Cleans up code so we are not repeating a duplicate loop, by
checking both transmit and receive queues in a single loop. Also cleans
up flags never used, so remove the definitions.
Alex does cleanup so that we are always updating pf->flags when a change
is made to the private flags. Adds support for 3K buffers to the receive
path so that we can provide the additional padding needed in the event
of NET_IP_ALIGN being non-zero or a cache line being greater than 64.
Adds support for build_skb() to i40e/i40evf.
Maciej adjusts the scope of the rtnl lock held during reset because it
was stopping other PFs from running their reset procedures.
Alan reduces code complexity in i40e_detect_recover_hung_queue().
