Commit 10d3be569243 ("tcp-tso: do not split TSO packets at retransmit
time") may directly retrans a multiple segments TSO/GSO packet without
split, Since this commit, we can no longer assume that a retransmitted
packet is a single segment.
This patch fixes the tp->undo_retrans accounting in tcp_sacktag_one()
that use the actual segments(pcount) of the retransmitted packet.
Before that commit (10d3be569243), the assumption underlying the
tp->undo_retrans-- seems correct.

Staged submission consists of multiple command submissions.
In order to be explicit, driver should return a single cs sequence
for every cs in the submission, or else user may try to wait on
an internal CS rather than waiting for the whole submission.

Add handling for case where the user doesn't set wait offset,
and keeps it as 0. In such a case the driver will decrement one
from this zero value which will cause the code to wait for
wrong number of signals.
The solution is to treat this case as in legacy wait cs,
and wait for the next signal.

Due to FLR scenario when running inside a VM, we must not use indirect

In case of single staged cs with both first/last indications
set, we reach a scenario where in cs_release function flow
we don't cancel the TDR work before freeing the cs memory,
this lead to kernel OOPs since when the timer expires
the work pointer will be freed already.
In addition treat wait encaps cs "not found" handle
as "OK" for the user in order to keep the user interface
for both legacy and encpas signal/wait features the same.

We have a potential race where a user interrupt can be received
in between user thread value comparison and before request was
added to wait list. This means that if no consecutive interrupt
will be received, user thread will timeout and fail.
The solution is to add the request to wait list before we
perform the comparison.

There have been reports of approximately a 0.9%-1.7% failure rate in SMU
communication timeouts with s0i3 entry on some OEM designs. Currently
the design in amd-pmc is to try every 100us for up to 20ms.
However the GPU driver which also communicates with the SMU using a
mailbox register which the driver polls every 1us for up to 2000ms.
In the GPU driver this was increased by commit 055162645a40 ("drm/amd/pm:
increase time out value when sending msg to SMU")
Increase the maximum timeout used by amd-pmc to 2000ms to match this
behavior. This has been shown to improve the stability for machines
that randomly have failures.

There are two bugs:
1) If ida_simple_get() fails then this code calls put_device(carrier)
but we haven't yet called get_device(carrier) and probably that
leads to a use after free.
2) After device_initialize() then we need to use put_device() to
release the bus. This will free the internal resources tied to the
device and call mcb_free_bus() which will free the rest.

It has been observed with certain PCIe USB cards (like Inateck connected
to AM64 EVM or J7200 EVM) that as soon as the primary roothub is
registered, port status change is handled even before xHC is running
leading to cold plug USB devices not detected. For such cases, registering
both the root hubs along with the second HCD is required. Add support for
deferring roothub registration in usb_add_hcd(), so that both primary and
secondary roothubs are registered along with the second HCD.

According USB spec each ISOC transaction should be performed in a
designated for that transaction interval. On bus errors or delays
in operating system scheduling of client software can result in no
packet being transferred for a (micro)frame. An error indication
should be returned as status to the client software in such a case.
Current implementation in case of missed/dropped interval send same
data in next possible interval instead of reporting missed isoc.
This fix complete requests with -ENODATA if interval elapsed.
HSOTG core in BDMA and Slave modes haven't HW support for
(micro)frames tracking, this is why SW should care about tracking
of (micro)frames. Because of that method and consider operating
system scheduling delays, added few additional checking's of elapsed
target (micro)frame:
1. Immediately before enabling EP to start transfer.
2. With any transfer completion interrupt.
3. With incomplete isoc in/out interrupt.
4. With EP disabled interrupt because of incomplete transfer.
5. With OUT token received while EP disabled interrupt (for OUT
transfers).
6. With NAK replied to IN token interrupt (for IN transfers).
As part of ISOC flow, additionally fixed 'current' and 'target' frame
calculation functions. In HS mode SOF limits provided by DSTS register
is 0x3fff, but in non HS mode this limit is 0x7ff.

After we start to do core soft reset while usb role switch,
the phy init is invoked at every switch to device mode, but
its counter part de-init is missing, this causes the actual
phy init can not be done when we really want to re-init phy
like system resume, because the counter maintained by phy
core is not 0. considering phy init is actually redundant for
role switch, so move out the phy init from core soft reset to
dwc3 core init where is the only place required.

This reverts commit f3de5d857bb2362b00e2a8d4bc886cd49dcb66db.
That commit broke USB on all routers that have USB always powered on and
don't require toggling any GPIO. It's a majority of devices actually.
The original code worked and seemed safe: vcc GPIO is optional and
bcma_hci_platform_power_gpio() takes care of checking the pointer before
using it.
This revert fixes:

If the driver runs out of minor numbers it would release minor 0 and
allow another device to claim the minor while still in use.
Fortunately, registering the tty class device of the second device would
fail (with a stack dump) due to the sysfs name collision so no memory is
leaked.

For DEV_VER_V3 version there exist race condition between clearing
ep_sts.EP_STS_TRBERR and setting ep_cmd.EP_CMD_DRDY bit.
Setting EP_CMD_DRDY will be ignored by controller when
EP_STS_TRBERR is set. So, between these two instructions we have
a small time gap in which the EP_STSS_TRBERR can be set. In such case
the transfer will not start after setting doorbell.

This loop is supposed to loop until if reads something other than
CS_IDST or until it times out after 30,000 attempts. But because of
the || vs && bug, it will never time out and instead it will loop a
minimum of 30,000 times.
This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE
so it probably doesn't affect regular usage.

The patch increases the bitshift in feedback frequency
calculation with EP-OUT bInterval value.
Tests have revealed that Win10 and OSX UAC2 drivers require
the feedback frequency to be based on the actual packet
interval instead of on the USB2 microframe. Otherwise they
ignore the feedback value. Linux snd-usb-audio driver
detects the applied bitshift automatically.

Dispatching requests inline with the .queue_rq() call may block while
holding the send_mutex. If the tcp io_work also happens to schedule, it
may see the req_list is non-empty, leaving "pending" true and remaining
in TASK_RUNNING. Since io_work is of higher scheduling priority, the
.queue_rq task may not get a chance to run, blocking forward progress
and leading to io timeouts.
Instead of checking for pending requests within io_work, let the queueing
restart io_work outside the send_mutex lock if there is more work to be
done.

The variable master is being masked with ~MST_R_BITS however this
masked value is never used, the following updates to master are
assignments. I suspect the original intention was to mask out the
MST_R_BITS and then bit-wise or in the appropriate read bits rather
than perform an assignment. Fix this by using the |= operator rather
than a straight assignment.
Note that this code is pre-git history, so I can't find a sha for
it.

There are two cases for machine check recovery:
1) The machine check was triggered by ring3 (application) code.
This is the simpler case. The machine check handler simply queues
work to be executed on return to user. That code unmaps the page
from all users and arranges to send a SIGBUS to the task that
triggered the poison.
2) The machine check was triggered in kernel code that is covered by
an exception table entry. In this case the machine check handler
still queues a work entry to unmap the page, etc. but this will
not be called right away because the #MC handler returns to the
fix up code address in the exception table entry.
Problems occur if the kernel triggers another machine check before the
return to user processes the first queued work item.
Specifically, the work is queued using the ->mce_kill_me callback
structure in the task struct for the current thread. Attempting to queue
a second work item using this same callback results in a loop in the
linked list of work functions to call. So when the kernel does return to
user, it enters an infinite loop processing the same entry for ever.
There are some legitimate scenarios where the kernel may take a second
machine check before returning to the user.
1) Some code (e.g. futex) first tries a get_user() with page faults
disabled. If this fails, the code retries with page faults enabled
expecting that this will resolve the page fault.
2) Copy from user code retries a copy in byte-at-time mode to check
whether any additional bytes can be copied.
On the other side of the fence are some bad drivers that do not check
the return value from individual get_user() calls and may access
multiple user addresses without noticing that some/all calls have
failed.
Fix by adding a counter (current->mce_count) to keep track of repeated
machine checks before task_work() is called. First machine check saves
the address information and calls task_work_add(). Subsequent machine
checks before that task_work call back is executed check that the address
is in the same page as the first machine check (since the callback will
offline exactly one page).
Expected worst case is four machine checks before moving on (e.g. one
user access with page faults disabled, then a repeat to the same address
with page faults enabled ... repeat in copy tail bytes). Just in case
there is some code that loops forever enforce a limit of 10.
