The hardware has the HW Checksum Offload bug when small
TCP patckets (with length <= 60 bytes) has wrong "checksum valid" bit.
The solution is - ignore checksum valid bit for small packets
(with length <= 60 bytes) and mark this as CHECKSUM_NONE to allow
network stack recalculate checksum itself.

vmwgfx currently cannot support non-blocking commit because when
vmw_*_crtc_page_flip is called, drm_atomic_nonblocking_commit()
schedules the update on a thread. This means vmw_*_crtc_page_flip
cannot rely on the new surface being bound before the subsequent
dirty and flush operations happen.

Compare the number of bytes actually seen on the wire to the byte
count field returned by the slave device.
Previously we just overwrote the byte count returned by the slave
with the real byte count and let the caller figure out if the
message was sane.

According to Table 15-14 of the C2000 EDS (Intel doc #510524) the
rx data pointed to by the descriptor dptr contains the byte count.
desc->rxbytes reports all bytes read on the wire, including the
"byte count" byte. So if a device sends 4 bytes in response to a
block read, on the wire and in the DMA buffer we see:
count data1 data2 data3 data4
0x04 0xde 0xad 0xbe 0xef
That's what we want to return in data->block to the next level.
Instead we were actually prefixing that with desc->rxbytes:
bad
count count data1 data2 data3 data4
0x05 0x04 0xde 0xad 0xbe 0xef
This was discovered while developing a BMC solution relying on the
ipmi_ssif.c driver which was trying to interpret the bogus length
field as part of the IPMI response.

Pull libata fixes from Tejun Heo:
"Late fixes for libata. There's a minor platform driver fix but the
important one is READ LOG PAGE.
This is a new ATA command which is used to test some optional features
but it broke probing of some devices - they locked up instead of
failing the unknown command.
Christoph tried blacklisting, but, after finding out there are
multiple devices which fail this way, backed off to testing feature
bit in IDENTIFY data first, which is a bit lossy (we can miss features
on some devices) but should be a lot safer"

This reverts commit 35f0b6a779b8b7a98faefd7c1c660b4dac9a5c26.
We now conditionalize issuing of READ LOG PAGE on the TRUSTED
COMPUTING SUPPORTED bit in the identity data and this shouldn't be

ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of
the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE
command to avoid issues with buggy devices. The only downside is that
we can't support Security Send / Receive for a device with an older
revision due to the conflicting use of this field in earlier
specifications.
tj: The reason we need this is because some devices which don't
support READ LOG PAGE lock up after getting issued that command.

Passing commands for logging to t4_record_mbox() with size
MBOX_LEN, when the actual command size is actually smaller,
causes out-of-bounds stack accesses in t4_record_mbox() while
copying command words here:
for (i = 0; i < size / 8; i++)
entry->cmd[i] = be64_to_cpu(cmd[i]);
Up to 48 bytes from the stack are then leaked to debugfs.
This happens whenever we send (and log) commands described by
structs fw_sched_cmd (32 bytes leaked), fw_vi_rxmode_cmd (48),
fw_hello_cmd (48), fw_bye_cmd (48), fw_initialize_cmd (48),
fw_reset_cmd (48), fw_pfvf_cmd (32), fw_eq_eth_cmd (16),
fw_eq_ctrl_cmd (32), fw_eq_ofld_cmd (32), fw_acl_mac_cmd(16),

fw_devlog_cmd(32), fw_vi_enable_cmd(48), fw_port_cmd(32),
fw_sched_cmd(32), fw_devlog_cmd(32).
The cxgb4vf driver got this right instead.
When we call t4_record_mbox() to log a command reply, a MBOX_LEN
size can be used though, as get_mbox_rpl() will fill cmd_rpl up
completely.

The mac address is only retrieved from h/w when using PPv2.1. Otherwise
the variable holding it is still checked and used if it contains a valid
value. As the variable isn't initialized to an invalid mac address
value, we end up with random mac addresses which can be the same for all
the ports handled by this PPv2 driver.
Fixes this by initializing the h/w mac address variable to {0}, which is
an invalid mac address value. This way the random assignation fallback
is called and all ports end up with their own addresses.

User-modified input settings no longer survive a suspend/resume cycle.
Starting with 4.12, the touchpad is reinitialized on every reconnect
because the hardware appears to be different. This can be reproduced
by running the following as root:
echo -n reconnect >/sys/devices/platform/i8042/serio1/drvctl
A line like the following will show up in dmesg:
[30378.295794] psmouse serio1: synaptics: hardware appears to be
different: id(149271-149271), model(114865-114865),
caps(d047b3-d047b1), ext(b40000-b40000).
Note the single bit difference in caps: bit 1 (SYN_CAP_MULTIFINGER).
This happens because we modify our stored copy of the device info
capabilities when we enable advanced gesture mode but this change is
not reflected in the actual hardware capabilities.
It worked in the past because synaptics_query_hardware used to modify
the stored synaptics_device_info struct instead of filling in a new
one, as it does now.
Fix it by no longer faking the SYN_CAP_MULTIFINGER bit when setting
advanced gesture mode. This necessitated a small refactoring.

In xen_blkif_disconnect, before checking inflight I/O, following code
stops the blkback thread,
if (ring->xenblkd) {
kthread_stop(ring->xenblkd);
wake_up(&ring->shutdown_wq);
}
If there is inflight I/O in any non-last queue, blkback returns -EBUSY
directly, and above code would not be called to stop thread of remaining
queue and processs them. When removing vbd device with lots of disk I/O
load, some queues with inflight I/O still have blkback thread running even
though the corresponding vbd device or guest is gone.
And this could cause some problems, for example, if the backend device type
is file, some loop devices and blkback thread always lingers there forever
after guest is destroyed, and this causes failure of umounting repositories
unless rebooting the dom0.
This patch allows thread of every queue has the chance to get stopped.
Otherwise, only thread of queue previous to(including) first busy one get
stopped, blkthread of remaining queue will still run. So stop all threads
properly and return -EBUSY if any queue has inflight I/O.

The message printed on disk resize is incorrect. The following is
printed when resizing to 2 GiB:
$ truncate -s 1G test.img
$ qemu -device virtio-blk-pci,logical_block_size=4096,...
(qemu) block_resize drive1 2G
virtio_blk virtio0: new size: 4194304 4096-byte logical blocks (17.2 GB/16.0 GiB)
The virtio_blk capacity config field is in 512-byte sector units
regardless of logical_block_size as per the VIRTIO specification.
Therefore the message should read:
virtio_blk virtio0: new size: 524288 4096-byte logical blocks (2.15 GB/2.0 GiB)
Note that this only affects the printed message. Thankfully the actual
block device has the correct size because the block layer expects
capacity in sectors.

There is a deadlock possible when canceling the link status
delayed work queue. The removal process is run with RTNL held,
and the link status callback is acquring RTNL.
Resolve the issue by using trylock and rescheduling.
If cancel is in process, that block it from happening.

Version 4 of the ONFI spec mandates that tADL be at least 400 nanoseconds,
but, depending on the master clock rate, 400 ns may not fit in the tADL
field of the SMC reg. We need to relax the check and accept the -ERANGE
return code.
Note that previous versions of the ONFI spec had a lower tADL_min (100 or
200 ns). It's not clear why this timing constraint got increased but it
seems most NANDs are fine with values lower than 400ns, so we should be
safe.

The debugfs entries must be removed before an error is returned in the
probe function. Otherwise another try to load the module fails and when
the debugfs files are accessed without the module loaded, the kernel
still tries to call a function in that module.

In case bcm_sysport_init_tx_ring() is not able to allocate ring->cbs, we
would return with an error, and call bcm_sysport_fini_tx_ring() and it
would see that ring->cbs is NULL and do nothing. This would leak the
coherent DMA descriptor area, so we need to free it on error before
returning.

There are 3 spots where we call dev_kfree_skb() but we are actually
just doing a normal SKB consumption: __bcmgenet_tx_reclaim() for normal
TX reclamation, bcmgenet_alloc_rx_buffers() during the initial RX ring
setup and bcmgenet_free_rx_buffers() during RX ring cleanup.
