Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.
This fixes the touchpad not being detected properly on Asus PU551LA

I've had reports of UEFI platforms failing iSCSI boot in various
configurations, that ended up being caused by network initialization
scripts getting tripped up by unexpected null addresses (0.0.0.0) being
reported for gateways, dhcp servers, and dns servers.
The tianocore EDK2 iSCSI driver generates an iBFT table that always uses
IPv4-mapped IPv6 addresses for the NIC structure fields. This results
in values that are "not present or not specified" being reported as
::ffff:0.0.0.0 rather than all zeros as specified.
The iscsi_ibft module filters unspecified fields from the iBFT from
sysfs, preventing userspace from using invalid values and making it easy
to check for the presence of a value. This currently fails in regard to
these mapped null addresses.
In order to remain consistent with how the iBFT information is exposed,
we should accommodate the behavior of the tianocore iSCSI driver as it's
already in the wild in a large number of servers.
Tested under qemu using an OVMF build of tianocore EDK2.

In d74b9027a4da ("PCI: Consider additional PF's IOV BAR alignment in sizing
and assigning"), we store additional alignment in realloc_head and take
this into consideration for assignment.
In __assign_resources_sorted(), we changed dev_res->res->start, then used
resource_start() (which depends on res->start), so the recomputed res->end
was completely bogus. Even if we'd had the correct size, the end would
have been off by one.
Preserve the resource size when we adjust its alignment.

In d74b9027a4da ("PCI: Consider additional PF's IOV BAR alignment in sizing
and assigning"), it stores additional alignment in realloc_head and takes
this into consideration for assignment.
After getting the additional alignment, it reorders the head list so
resources with bigger alignment are ahead of resources with smaller
alignment. It does this by iterating over the head list and inserting
ahead of any resource with smaller alignment. This should be done for the
first occurrence, but the code currently iterates over the whole list.
Fix this by terminating the loop when we find the first smaller resource in
the head list.

This reverts commit 5fc872c7323534e8f7dc21bab635e7a9b9659e07.
The DMA-API does not strictly require that the memory
returned by dma_alloc_coherent is zeroed out. For that
another function (dma_zalloc_coherent) should be used. But
all other x86 DMA-API implementation I checked zero out the
memory, so that some drivers rely on it and break when it is
not.
It seems the (driver-)world is not yet ready for this
change, so revert it.

The pl330 device could hang infinitely on certain boards when DMA
channels are terminated.
It was caused by lack of runtime resume when executing
pl330_terminate_all() which calls the _stop() function. _stop() accesses
device register and can loop infinitely while checking for device state.
The hang was confirmed by Dinh Nguyen on Altera SOCFPGA Cyclone V
board during boot. It can be also triggered with:
$ echo 1 > /sys/module/dmatest/parameters/iterations
$ echo dma1chan0 > /sys/module/dmatest/parameters/channel
$ echo 1 > /sys/module/dmatest/parameters/run
$ sleep 1

Pull block layer fixes from Jens Axboe:
"Sending this off now, as I'm not aware of other current bugs, nor do I
expect further fixes before 4.1 final. This contains two fixes:
- a fix for a bdi unregister warning that gets spewed on md, due to a
regression introduced earlier in this cycle. From Neil Brown.
- a fix for a compile warning for NVMe on 32-bit platforms, also a
regression introduced in this cycle. From Arnd Bergmann"

A recent change to the ioctl handling caused a new harmless
warning in the NVMe driver on all 32-bit machines:
drivers/block/nvme-core.c: In function 'nvme_submit_io':
drivers/block/nvme-core.c:1794:29: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
In order to shup up that warning, this introduces a new
temporary variable that uses a double cast to extract
the pointer from an __u64 structure member.

Pull networking fixes from David Miller:
1) Various VTI tunnel (mark handling, PMTU) bug fixes from Alexander
Duyck and Steffen Klassert.
2) Revert ethtool PHY query change, it wasn't correct. The PHY address
selected by the driver running the PHY to MAC connection decides
what PHY address GET ethtool operations return information from.
3) Fix handling of sequence number bits for encryption IV generation in
ESP driver, from Herbert Xu.
4) UDP can return -EAGAIN when we hit a bad checksum on receive, even
when there are other packets in the receive queue which is wrong.
Just respect the error returned from the generic socket recv
datagram helper. From Eric Dumazet.
5) Fix BNA driver firmware loading on big-endian systems, from Ivan
Vecera.
6) Fix regression in that we were inheriting the congestion control of
the listening socket for new connections, the intended behavior
always was to use the default in this case. From Neal Cardwell.
7) Fix NULL deref in brcmfmac driver, from Arend van Spriel.
8) OTP parsing fix in iwlwifi from Liad Kaufman.

by mistake. This broke several 8260 devices.

The cmd_in_flight tracking was introduced to workaround faulty
power management hardware, by having the driver keep the NIC
awake as long as there are commands in flight. However, some of
the code handling this workaround was unconditionally executed,
which resulted with an inconsistent state where the driver assumed
that the NIC was awake although it wasn't.
Fix this by renaming 'cmd_in_flight' to 'cmd_hold_nic_awake' and
handling the NIC requested awake state only for hardwares for
which the workaround is needed.

Commit dff173de84958 ("bnx2x: Fix statistics locking scheme") changed the
bnx2x locking around statistics state into using a mutex - but the lock
is being accessed via a timer which is forbidden.
[If compiled with CONFIG_DEBUG_MUTEXES, logs show a warning about
accessing the mutex in interrupt context]
This moves the implementation into using a semaphore [with size '1']
instead.

When we come to tear things down in netback_remove() and generate the
uevent it is possible that the xenstore directory has already been
removed (details below).
In such cases netback_uevent() won't be able to read the hotplug
script and will write a xenstore error node.
A recent change to the hypervisor exposed this race such that we now
sometimes lose it (where apparently we didn't ever before).
Instead read the hotplug script configuration during setup and use it
for the lifetime of the backend device.
The apparently more obvious fix of moving the transition to
state=Closed in netback_remove() to after the uevent does not work
because it is possible that we are already in state=Closed (in
reaction to the guest having disconnected as it shutdown). Being
already in Closed means the toolstack is at liberty to start tearing
down the xenstore directories. In principal it might be possible to
arrange to unregister the device sooner (e.g on transition to Closing)
such that xenstore would still be there but this state machine is
fragile and prone to anger...
A modern Xen system only relies on the hotplug uevent for driver
domains, when the backend is in the same domain as the toolstack it
will run the necessary setup/teardown directly in the correct sequence
wrt xenstore changes.

When Rx packet data must be dropped, all the buffers
associated with that Rx packet must be freed. Extend
and rename efx_free_rx_buffer() to efx_free_rx_buffers()
and loop through all the fragments.
By doing so this patch fixes a possible memory leak.

Bug in the driver initialization causes soft-lockup if firmware
initialization timeout is reached. Polling function bfa_ioc_poll_fwinit()
incorrectly calls bfa_nw_iocpf_timeout() when the timeout is reached.
The problem is that bfa_nw_iocpf_timeout() calls again
bfa_ioc_poll_fwinit()... etc. The bfa_ioc_poll_fwinit() should directly
send timeout event for iocpf and the same should be done if firmware
download into HW fails.

Driver starts iocpf timer prior bnad_ioceth_enable() call and this is
unreasonable. This piece of code probably originates from Brocade/Qlogic
out-of-box driver during initial import into upstream. This driver uses
only one timer and queue to implement multiple timers and this timer is
started at this place. The upstream driver uses multiple timers instead
of this.

Firmware required by bna is stored in appropriate files as sequence
of LE32 integers. After loading by request_firmware() they need to be
byte-swapped on big-endian arches. Without this conversion the NIC
is unusable on big-endian machines.

native endianness. There is therefore no need to byte swap the accesses
on big endian targets, so convert the Fast Debug Channel (FDC) TTY
driver to use __raw_readl()/__raw_writel() rather than
ioread32()/iowrite32().

- remaining TCM-USER -v2 related changes to enforce full CDB

We don't assign pi_ctx to desc->pi_ctx until we're certain to succeed
in the function. That means the cleanup path should use the local

Aside from whether they handle BIDI ops or not, parsing of the CDB by

After much discussion, give up on only passing a subset of SCSI commands
to userspace and pass them all. Based on what pscsi is doing, make sure
to set SCF_SCSI_DATA_CDB for I/O ops, and define attributes identical to
pscsi.
Make hw_block_size configurable via dev param.

There is just one configfs subsystem in the target code, so we might as
well add two helpers to reference / unreference it from the core code
instead of passing pointers to it around.
This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6,
where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would
fail, because the assignment from the original target_core_subsystem[]
is no longer happening at target_register_template() time.

Once upon a time, iscsit_get_tpg() was using an un-interruptible
lock. The signal_pending() usage was a check to allow userspace
to break out of the operation with SIGINT.
AFAICT, there's no reason why this is necessary anymore, and as
reported by Alexey can be potentially dangerous. Also, go ahead
and drop the other two problematic cases within iscsit_access_np()
and sbc_compare_and_write() as well.

Code like " &= ~CMD_T_BUSY | ..." only clears CMD_T_BUSY but not
the other flag. Modify these statements such that both flags are
cleared.

The function transport_complete_qf() must call either
queue_data_in() or queue_status() but not both.

TCMU requires more work to correctly handle both user handlers that want
all SCSI commands (pass_level=0) for a se_device, and also handlers that
just want I/O commands and let the others be emulated by the kernel
(pass_level=1). Only support the latter for now.
For full passthrough, we will need to support a second se_subsystem_api
template, due to configfs attributes being different between the two modes.
Thus pass_level is extraneous, and we can remove it.
The ABI break for TCMU v2 is already applied for this release, so it's
best to do this now to avoid another ABI break in the future.
