For some controllers, in Present State Register, Data Line
Active bit is not reliable for commands (such as CMD6, CMD7,
CMD12, CMD28, CMD29, or CMD38) with busy signal. DLA affects
Command with Data Inhibit bit. Therefore, software driver
may not know the busy status in DLA/CDIHB.
Futunately MMC core driver has already polled card status
with CMD13 after sending any command with busy signal. So
we can just ignore CDIHB never released issue for such
controllers. This patch is to add a quirk to handle this.

Invalid Transfer Complete (IRQSTAT[TC]) bit could be set during
multi-write operation even when the BLK_CNT in BLKATTR register
has not reached zero. Therefore, Transfer Complete might be
reported twice due to this erratum since a valid Transfer Complete
occurs when BLK_CNT reaches zero. This erratum is to fix this issue

In the event of that any data error (like, IRQSTAT[DCE]) occurs
during an eSDHC data transaction where DMA is used for data
transfer to/from the system memory, setting the SYSCTL[RSTD]
register may cause a system hang. If software sets the register
SYSCTL[RSTD] to 1 for error recovery while DMA transferring is
not complete, eSDHC may hang the system bus. This happens because
the software register SYSCTL[RSTD] resets the DMA engine without
waiting for the completion of pending system transactions. This
erratum is to fix this issue.

eSDHC-A001: The data timeout counter (SYSCTL[DTOCV]) is not
reliable for DTOCV values 0x4(2^17 SD clock), 0x8(2^21 SD clock),
and 0xC(2^25 SD clock). The data timeout counter can count from
2^13–2^27, but for values 2^17, 2^21, and 2^25, the timeout
counter counts for only 2^13 SD clocks.
A-008358: The data timeout counter value loaded into the timeout
counter is less than expected and can result into early timeout
error in case of eSDHC data transactions. The table below shows
the expected vs actual timeout period for different values of
SYSCTL[DTOCV]:
these two erratum has the same quirk to control it, and set
SDHCI_QUIRK_RESET_AFTER_REQUEST to fix above issue.

Code which initializes the "clk_init_data.ops" checks pll->rate_table
before that field is ever assigned to so it always picks
"clk_pll1416x_min_ops".
This breaks dynamic rate rounding for features such as cpufreq.

The nvme target hadn't been taking the Get Log Page offset parameter
into consideration, and so has been returning corrupted log pages when
offsets are used. Since many tools, including nvme-cli, split the log
request to 4k, we've been breaking discovery log responses when more
than 3 subsystems exist.
Fix the returned data by internally generating the entire discovery
log page and copying only the requested bytes into the user buffer. The
command log page offset type has been modified to a native __le64 to
make it easier to extract the value from a command.

This patch fixes a long-standing bug that initialized the FC-NVME
cmnd iu CSN value to 1. Early FC-NVME specs had the connection starting
with CSN=1. By the time the spec reached approval, the language had
changed to state a connection should start with CSN=0. This patch
corrects the initialization value for FC-NVME connections.
Additionally, in reviewing the transport, the CSN value is assigned to
the new IU early in the start routine. It's possible that a later dma
map request may fail, causing the command to never be sent to the
controller. Change the location of the assignment so that it is
immediately prior to calling the lldd. Add a comment block to explain
the impacts if the lldd were to additionally fail sending the command.

commit 5b0d62108b46 ("mmc: sdhci-omap: Add platform specific reset
callback") skips data resets during tuning operation. Because of this,
a data error or data finish interrupt might still arrive after a command
error has been handled and the mrq ended. This ends up with a "mmc0: Got
data interrupt 0x00000002 even though no data operation was in progress"
error message.
Fix this by adding a platform specific callback for sdhci_irq. Mark the
mrq as a failure but wait for a data interrupt instead of calling
finish_mrq().

During a safe hot remove, the OS powers off the slot, which may cause a
Data Link Layer State Changed event. The slot has already been set to
OFF_STATE, so that event results in re-enabling the device, making it
impossible to safely remove it.
Clear out the Presence Detect Changed and Data Link Layer State Changed
events when the disabled slot has settled down.
It is still possible to re-enable the device if it remains in the slot
after pressing the Attention Button by pressing it again.
Fixes the problem that Micah reported below: an NVMe drive power button may
not actually turn off the drive.

- Several bug fixes for the hfi1 driver 'TID RDMA' functionality
merged into 5.1. Since TID RDMA is on by default these all seem to
be regressions.
- Wrong software permission checks on memory in mlx5
- Memory leak in vmw_pvrdma during driver remove
- Several bug fixes for hns driver features merged into 5.1"

The introduction of multipage bio vectors broke pblk's partial read
logic due to it not being prepared for multipage bio vectors.
Use bio vector iterators instead of direct bio vector indexing.

When a QP is put into error state, the send queue will be flushed.
This mechanism is implemented in both the first and the second leg
of the send engine. Since the second leg is only responsible for
data transactions in the KDETH space for the TID RDMA WRITE request,
it should not perform the flushing of the send queue.
This patch removes the flushing function of the second leg, but
still keeps the bailing out of the QP if it is put into error state.
Fixes: 70dcb2e3dc6a ("IB/hfi1: Add the TID second leg send packet builder")

Commit 7769db588384 ("drm/i915/dp: optimize eDP 1.4+ link config fast
and narrow") started to optize the eDP 1.4+ link config, both per spec
and as preparation for display stream compression support.
Sadly, we again face panels that flat out fail with parameters they
claim to support. Revert, and go back to the drawing board.
v2: Actually revert to max params instead of just wide-and-slow.

nvme_cancel_request() is used in error handler, and it is always
reliable to cancel request synchronously, and avoids possible race
in which request may be completed after real hw queue is destroyed.
One issue is reported by our customer on NVMe RDMA, in which freed ib
queue pair may be used in nvme_rdma_complete_rq().
