7321f47ead KVM: x86: hyper-v: Fix the maximum number of sparse banks for XMM fast TLB flush hypercalls
When TLB flush hypercalls (HVCALL_FLUSH_VIRTUAL_ADDRESS_{LIST,SPACE}_EX are
issued in 'XMM fast' mode, the maximum number of allowed sparse_banks is
not 'HV_HYPERCALL_MAX_XMM_REGISTERS - 1' (5) but twice as many (10) as each
XMM register is 128 bit long and can hold two 64 bit long banks.

bc5c75e0a5 nvmem: qfprom: Increase fuse blow timeout to prevent write fail
sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout.
Current timeout is simply too low. Since blowing fuses is a
very rare operation, so the risk associated with overestimating this
number is low.
Increase fuse blow timeout from 1ms to 10ms.

91b0383fef net: dcb: flush lingering app table entries for unregistered devices
If I'm not mistaken (and I don't think I am), the way in which the
dcbnl_ops work is that drivers call dcb_ieee_setapp() and this populates
the application table with dynamically allocated struct dcb_app_type
entries that are kept in the module-global dcb_app_list.

However, nobody keeps exact track of these entries, and although
dcb_ieee_delapp() is supposed to remove them, nobody does so when the
interface goes away (example: driver unbinds from device). So the
dcb_app_list will contain lingering entries with an ifindex that no
longer matches any device in dcb_app_lookup().

Reclaim the lost memory by listening for the NETDEV_UNREGISTER event and
flushing the app table entries of interfaces that are now gone.

In fact something like this used to be done as part of the initial
commit (blamed below), but it was done in dcbnl_exit() -> dcb_flushapp(),
essentially at module_exit time. That became dead code after commit
7a6b6f515f ("DCB: fix kconfig option") which essentially merged
"tristate config DCB" and "bool config DCBNL" into a single "bool config
DCB", so net/dcb/dcbnl.c could not be built as a module anymore.

Commit 36b9ad8084 ("net/dcb: make dcbnl.c explicitly non-modular")
recognized this and deleted dcbnl_exit() and dcb_flushapp() altogether,
leaving us with the version we have today.

Since flushing application table entries can and should be done as soon
as the netdevice disappears, fundamentally the commit that is to blame
is the one that introduced the design of this API.

9f1c50cf39 net/smc: fix connection leak
There's a potential leak issue under following execution sequence :

smc_release  				smc_connect_work
if (sk->sk_state == SMC_INIT)
					send_clc_confirim
	tcp_abort();
					...
					sk.sk_state = SMC_ACTIVE
smc_close_active
switch(sk->sk_state) {
...
case SMC_ACTIVE:
	smc_close_final()
	// then wait peer closed

Unfortunately, tcp_abort() may discard CLC CONFIRM messages that are
still in the tcp send buffer, in which case our connection token cannot
be delivered to the server side, which means that we cannot get a
passive close message at all. Therefore, it is impossible for the to be
disconnected at all.

This patch tries a very simple way to avoid this issue, once the state
has changed to SMC_ACTIVE after tcp_abort(), we can actively abort the
smc connection, considering that the state is SMC_INIT before
tcp_abort(), abandoning the complete disconnection process should not
cause too much problem.

In fact, this problem may exist as long as the CLC CONFIRM message is
not received by the server. Whether a timer should be added after
smc_close_final() needs to be discussed in the future. But even so, this
patch provides a faster release for connection in above case, it should
also be valuable.

087a7b944c net: stmmac: only enable DMA interrupts when ready
In this driver's ->ndo_open() callback, it enables DMA interrupts,
starts the DMA channels, then requests interrupts with request_irq(),
and then finally enables napi.

If RX DMA interrupts are received before napi is enabled, no processing
is done because napi_schedule_prep() will return false.  If the network
has a lot of broadcast/multicast traffic, then the RX ring could fill up
completely before napi is enabled.  When this happens, no further RX
interrupts will be delivered, and the driver will fail to receive any
packets.

Fix this by only enabling DMA interrupts after all other initialization
is complete.

dcf4ff7a48 xen/netfront: destroy queues before real_num_tx_queues is zeroed
xennet_destroy_queues() relies on info->netdev->real_num_tx_queues to
delete queues. Since d7dac08341
("net-sysfs: update the queue counts in the unregistration path"),
unregister_netdev() indirectly sets real_num_tx_queues to 0. Those two
facts together means, that xennet_destroy_queues() called from
xennet_remove() cannot do its job, because it's called after
unregister_netdev(). This results in kfree-ing queues that are still
linked in napi, which ultimately crashes:

Fix this by calling xennet_destroy_queues() from xennet_uninit(),
when real_num_tx_queues is still available. This ensures that queues are
destroyed when real_num_tx_queues is set to 0, regardless of how
unregister_netdev() was called.

Merge branch 'set_fs-4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic into asm-generic
Christoph Hellwig and a few others spent a huge effort on removing
set_fs() from most of the important architectures, but about half the
other architectures were never completed even though most of them don't
actually use set_fs() at all.

I did a patch for microblaze at some point, which turned out to be fairly
generic, and now ported it to most other architectures, using new generic
implementations of access_ok() and __{get,put}_kernel_nocheck().

Three architectures (sparc64, ia64, and sh) needed some extra work,
which I also completed.

Only some old designs based on early beagleboard revisions with a miswired
timer need to use the alternative timer.

b814f7544a ARM: dts: stm32: remove timer5 duplicate unit-address on stm32f7 series
Remove the following warnings seen when building with W=1.
Warning (unique_unit_address): /soc/timer@40000c00: duplicate unit-address
(also used in node /soc/timers@40000c00)
This approach is based on some discussions[1], to restructure the dtsi
and dts files.

Timer5 is enabled by default on stm32f7 series, to act as clockevent. In
order to get rid of the W=1 warning, and be compliant with dt-schemas
(e.g. dtbs_check):
- In stm32f746.dtsi:
  . Keep the more complete timers5 description
  . Remove the most simple timer5 node that is duplicate
- In each board:
  . adopt "st,stm32-timer" compatible for timers5, also add the interrupt
  . use /delete-property/ and /delete-node/ so the it matches the
    clockevent bindings

Note: all this is done in one shot (e.g. not split) to keep clockevent
functionality.

e6bc0d6ac6 ARM: dts: stm32: remove some timer duplicate unit-address on stm32f7 series
Several unused "timer" are duplicate nodes of "timers" nodes.
There are two dt-schemas:
- timer/st,stm32-timer.yaml: A timer is needed on STM32F7 series, on all
  boards, to act as clockevent.
- mfd/st,stm32-timers.yaml: Timers can be used for other purpose.

By default, timer5 is left enabled to be used as clockevent. Remove all
other timer clockevent nodes that are currently unused and duplicated.

This removes several messages: Warning (unique_unit_address): /soc/timer@..
duplicate unit-address (also used in node /soc/timers@...)

0f18f728ba ARM: dts: stm32: add DMA configuration to UART nodes on stm32mp151
Add DMA configuration in stm32mp15x uart nodes by selecting dma direct
mode and alternate REQ/ACK dma protocol for uart.

DMA direct mode allows to bypass DMA FIFO. Each DMA request immediately
initiates a transfer from/to the memory. This allows USART to get data
transferred, even when the transfer ends before the DMA FIFO completion.

Default REQ/ACK DMA protocol consists in maintaining ACK signal up to the
removal of REQuest and the transfer completion.
In case of alternative REQ/ACK protocol, ACK de-assertion does not wait the
removal of the REQuest, but only the transfer completion.
Due to a possible DMA stream lock when transferring data to/from STM32
USART/UART, select this alternative protocol in STM32 USART/UART nodes.
