We've had several complaints about a 10s reconnect delay (the default)
when there was an error while there is connectivity to a subsystem.
The max_reconnects and reconnect_delay are set in common code prior to
calling the transport to create the controller.
This change checks if the default reconnect delay is being used, and if
so, it adjusts it to a shorter period (2s) for the nvme-fc transport.
It does so by calculating the controller loss tmo window, changing the
value of the reconnect delay, and then recalculating the maximum number
of reconnect attempts allowed.

On reconnect, the code currently does not freeze the controller before
possibly updating the number hw queues for the controller.
Add the freeze before updating the number of hw queues. Note: the queues
are already started and remain started through the reconnect.

The loop that backs out of hw io queue creation continues through index
0, which corresponds to the admin queue as well.
Fix the loop so it only proceeds through indexes 1..n which correspond to
I/O queues.

Currently, an I/O timeout unconditionally invokes
nvme_fc_error_recovery() which checks for LIVE or CONNECTING state. If
live, the routine resets the controller which initiates a reconnect -
which is valid. If CONNECTING, err_work is scheduled. Err_work then
calls the terminate_io routine, which also checks for CONNECTING and
noops any further action on outstanding I/O. The result is nothing
happened to the timed out io. As such, if the command was dropped on
the wire, it will never timeout / complete, and the connect process
will hang.
Change the behavior of the io timeout routine to unconditionally abort
the I/O. I/O completion handling will note that an io failed due to an
abort and will terminate the connection / association as needed. If the
abort was unable to happen, continue with a call to
nvme_fc_error_recovery(). To ensure something different happens in
nvme_fc_error_recovery() rework it so at it will abort all I/Os on the
association to force a failure.
As I/O aborts now may occur outside of delete_association, counting for
completion must be wary and only count those aborted during
delete_association when TERMIO is set on the controller.

Unmasking an event channel with fifo events channels being used can

The struct irq_info of Xen's event handling is used only for two
evtchn_ops functions outside of events_base.c. Those two functions
can easily be switched to avoid that usage.
This allows to make struct irq_info and its related access functions
private to events_base.c.

When starting a HP machine with HIL driver but without an HIL keyboard
or HIL mouse attached, it may happen that data written to the HIL loop
gets stuck (e.g. because the transaction queue is full). Usually one
will then have to reboot the machine because all you see is and endless
output of:
Transaction add failed: transaction already queued?
In the higher layers hp_sdc_enqueue_transaction() is called to queued up
a HIL packet. This function returns an error code, and this patch adds
the necessary checks for this return code and disables the HIL driver if
further packets can't be sent.
Tested on a HP 730 and a HP 715/64 machine.

Pull clk updates from Stephen Boyd:
"This contains no changes to the core framework. It is a collection of
various clk driver updates.
The biggest driver updates in terms of lines of code is the Allwinner
driver, closely followed by the Qualcomm and Mediatek drivers. All of
those hit high because we add so many lines of clk data. Coming in
fourth place is i.MX which also adds a bunch of clk data. This
accounts for the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for
various clk drivers that have baked in linux-next for a while. I
suppose one highlight or theme is that more clk drivers are being
updated to work as modules, which is interesting to see such critical
SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being
dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module
- Some kerneldoc fixes here and there
- A couple of minor i.MX clk data corrections
- Update audio clock inverter and fdiv2 flag on Amlogic g12
- Make amlogic clk drivers configurable in Kconfig
- Fix Renesas VSP clock names to match corrected hardware

The avs drivers are all SoC specific drivers that doesn't share any code.
Instead they are located in a directory, mostly to keep similar
functionality together. From a maintenance point of view, it makes better
sense to collect SoC specific drivers like these, into the SoC specific
directories.
Therefore, let's move the qcom-cpr driver to the qcom directory.

By default, we set the passthru request allocation flag such that it
returns the error in the following code path and we fail the I/O when
BLK_MQ_REQ_NOWAIT is used for request allocation :-
nvme_alloc_request()
blk_mq_alloc_request()
blk_mq_queue_enter()
if (flag & BLK_MQ_REQ_NOWAIT)
return -EBUSY; <-- return if busy.
On some controllers using BLK_MQ_REQ_NOWAIT ends up in I/O error where
the controller is perfectly healthy and not in a degraded state.
Block layer request allocation does allow us to wait instead of
immediately returning the error when we BLK_MQ_REQ_NOWAIT flag is not
used. This has shown to fix the I/O error problem reported under
heavy random write workload.
Remove the BLK_MQ_REQ_NOWAIT parameter for passthru request allocation
which resolves this issue.

Clean up some confusing elements of nvmet_passthru_map_sg() by returning
early if the request is greater than the maximum bio size. This allows
us to drop the sg_cnt variable.
This should not result in any functional change but makes the code
clearer and more understandable. The original code allocated a truncated
bio then would return EINVAL when bio_add_pc_page() filled that bio. The
new code just returns EINVAL early if this would happen.

nvmet_passthru_map_sg() only supports mapping a single BIO, not a chain
so the effective maximum transfer should also be limitted by
BIO_MAX_PAGES (presently this works out to 1MB).
For PCI passthru devices the max_sectors would typically be more
limitting than BIO_MAX_PAGES, but this may not be true for all passthru
devices.

When connecting a controller with a zero kato value using the following
command line
nvme connect -t tcp -n NQN -a ADDR -s PORT --keep-alive-tmo=0
the warning below can be reproduced:
WARNING: CPU: 1 PID: 241 at kernel/workqueue.c:1627 __queue_delayed_work+0x6d/0x90
with trace:

...
This is caused by queuing up an uninitialized work. Althrough the
keep-alive timer is disabled during allocating the controller (fixed in
0d3b6a8d213a), ka_work still has a chance to run (called by
nvmet_start_ctrl).

When a CQE has incorrect command id due do an error injection, the host
may find a request which is already freed. Dereferencing req->mr->rkey

A crash can happened when a connect is rejected. The host establishes
the connection after received ConnectReply, and then continues to send
the fabrics Connect command. If the controller does not receive the
ReadyToUse capsule, host may receive a ConnectReject reply.
Call nvme_rdma_destroy_queue_ib after the host received the
RDMA_CM_EVENT_REJECTED event. Then when the fabrics Connect command
times out, nvme_rdma_timeout calls nvme_rdma_complete_rq to fail the
request. A crash happenes due to use after free in
nvme_rdma_complete_rq.
nvme_rdma_destroy_queue_ib is redundant when handling the
RDMA_CM_EVENT_REJECTED event as nvme_rdma_destroy_queue_ib is already
called in connection failure handler.

The ether_setup function would add the IFF_TX_SKB_SHARING flag to the

However, this is not true. This driver may pad the frame (in eth_tx)
