PXA3xx platforms have 56 interrupts that are stored in two ICMR
registers. The code in pxa_irq_suspend() and pxa_irq_resume() however
does a simple division by 32 which only leads to one register being
saved at suspend and restored at resume time. The NAND interrupt
setting, for instance, is lost.
Fix this by using DIV_ROUND_UP() instead.

smc_release() calls a sock_put() for smc fallback sockets to cover
the passive closing sock_hold() in __smc_connect() and
smc_tcp_listen_work(). This does not make sense for sockets in state
SMC_LISTEN and SMC_INIT.
An SMC socket stays in state SMC_INIT if connect fails. The sock_put
in smc_connect_abort() does not cover all failures. Move it into
smc_connect_decline_fallback().

t4_get_flash_params() fails in a fatal fashion if the FLASH part isn't
one of the recognized parts. But this leads to desperate efforts to update
drivers when various FLASH parts which we are using suddenly become
unavailable and we need to substitute new FLASH parts. This has lead to
more than one Customer Field Emergency when a Customer has an old driver
and suddenly can't use newly shipped adapters.
This commit fixes this by simply assuming that the FLASH part is 4MB in
size if it can't be identified. Note that all Chelsio adapters will have
flash parts which are at least 4MB in size.

====================
tipc: fixes in duplicate address discovery function
commit 25b0b9c4e835 ("tipc: handle collisions of 32-bit node address
hash values") introduced new functionality that has turned out to
contain several bugs and weaknesses.
We address those in this series.

The setting of the node address is not thread safe, meaning that
two discoverers may decide to set it simultanously, with a duplicate
entry in the name table as result. We fix that with this commit.

The duplicate address discovery protocol is not safe against two
discoverers running in parallel. The one executing first after the
trial period is over will set the node address and change its own
message type to DSC_REQ_MSG. The one executing last may find that the
node address is already set, and never change message type, with the
result that its links may never be established.
In this commmit we ensure that the message type always is set correctly
after the trial period is over.

With the duplicate address discovery protocol for tipc nodes addresses
we introduced a one second trial period before a node is allocated a
hash number to use as address.
Unfortunately, we miss to handle the case when a regular LINK REQUEST/
RESPONSE arrives from a cluster node during the trial period. Such
messages are not ignored as they should be, leading to links setup
attempts while the node still has no address.

The function for checking if there is an node address conflict is
supposed to return a suggestion for a new address if it finds a
conflict, and zero otherwise. But in case the peer being checked
is previously unknown it does instead return a "suggestion" for
the checked address itself. This results in a DSC_TRIAL_FAIL_MSG
being sent unecessarily to the peer, and sometimes makes the trial
period starting over again.

====================
ravb/sh_eth: fix sleep in atomic by reusing shared ethtool handlers
For ages trivial changes to RAVB and SuperH ethernet links by means of
standard 'ethtool' trigger a 'sleeping function called from invalid

% ethtool -r eth0

The root cause is that an attempt to modify ECMR and GECMR registers
only when RX/TX function is disabled was too overcomplicated in its
original implementation, also processing of an optional Link Change
interrupt added even more complexity, as a result the implementation
was error prone.
The new locking scheme is confirmed to be correct by dumping driver
specific and generic PHY framework function calls with aid of ftrace
while running more or less advanced tests.
Please note that sh_eth patches from the series were built-tested only.
On purpose I do not add Fixes tags, the reused PHY handlers were added
way later than the fixed problems were firstly found in the drivers.
Changes from v1 to v2:
* the original patches are split to bugfixes and enhancements only,
both v1 and v2 series are absolutely equal in total, thus I omit
description of changes in individual patches,
* the latter implies that there should be no strict need for retesting,
but because formally two series are different, I have to drop the tags
given by Geert and Andrew, please send your tags again.

The change fixes sleep in atomic context bug, which is encountered
every time when link settings are changed by ethtool.
Since commit 35b5f6b1a82b ("PHYLIB: Locking fixes for PHY I/O
potentially sleeping") phy_start_aneg() function utilizes a mutex
to serialize changes to phy state, however that helper function is
called in atomic context under a grabbed spinlock, because
phy_start_aneg() is called by phy_ethtool_ksettings_set() and by
replaced phy_ethtool_sset() helpers from phylib.
Now duplex mode setting is enforced in ravb_adjust_link() only, also
now RX/TX is disabled when link is put down or modifications to E-MAC
registers ECMR and GECMR are expected for both cases of checked and
ignored link status pin state from E-MAC interrupt handler.

On some systems, we come out of the bootloader with some
gates set with the clock "enabled" but the reset also
asserted.
Since 8a53fc511c5e "clk: aspeed: Prevent reset if clock is enabled"
we check that enabled bit in aspeed_clk_enabled(), and do
nothing if already set.
This breaks when the above scenario occurs, as the clock
is enabled, but the reset still needs to be lifted.
This patch fixes it by also checking the reset bit (if any)
and treating a gate in "reset" as being disabled.

This patch disallows rbtree with single elements, which is causing
problems with the recent timeout support. Before this patch, you
could opt out individual set representations per module, which is
just adding extra complexity.

In order to fix this problem kindly, this commit don't turn off aspm but

In general, accessing userspace memory beyond the length of the supplied
buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via
sys_splice()) and privilege escalation inside userspace.
Fix it by using simple_read_from_buffer() instead of custom logic.

Commit 2f28e4c24b10e (thermal: armada: Clarify control registers
accesses) introduced the new thermal binding. The new binding extends
the second registers field size to 8. Switch to the new binding to fix
thermal reading values. Without this change the fix for errata #132698
introduced in commit 8c0b888f661 (thermal: armada: Change sensors trim
default value) has no effect.

Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.
With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.

USB-serial fixes for v4.18-rc4
Here are three fixes for broken control-transfer error handling, which
could lead to uninitialised slab data leaking to user space.
Included is also a new device id for cp210x.
All but the final two patches have been in linux-next with no reported
issues.

- se we can ... -> so we can ...

The comment line for addtree says "skip if -I has no parameter".
What it actually does is "drop if -I has no parameter". For example,
if you have the compiler flag '-I foo' (a space between), it will be
converted to 'foo'. This completely changes the meaning.
What we want is, "do nothing" for -I without parameter so that
'-I foo' is kept as-is.
