SCSI discard will damage discard stripe bio setting, eg, some fields are
changed. If the stripe is reused very soon, we have wrong bios setting. We
remove discard stripe from hash list, so next time the strip will be fully
initialized.
Suitable for backport to 3.7+.

SCSI layer will add new payload for discard request. If two bios are merged
to one, the second bio has bi_vcnt 1 which is set in raid5. This will confuse
SCSI and cause oops.

When operate harddisk and hit errors, md_set_badblocks is called after
scsi_restart_operations which already disabled the irq. but md_set_badblocks
will call write_sequnlock_irq and enable irq. so softirq can preempt the
current thread and that may cause a deadlock. I think this situation should
use write_sequnlock_irqsave/irqrestore instead.
I met the situation and the call trace is below:

(the first time rdev_set_badblock was call from interrupt context),
so this patch is appropriate for 3.5 and subsequent kernels.

Since:
commit 7ceb17e87bde79d285a8b988cfed9eaeebe60b86
md: Allow devices to be re-added to a read-only array.
spares are activated on a read-only array. In case of raid1 and raid10
personalities it causes that not-in-sync devices are marked in-sync
without checking if recovery has been finished.
If a read-only array is degraded and one of its devices is not in-sync
(because the array has been only partially recovered) recovery will be skipped.
This patch adds checking if recovery has been finished before marking a device
in-sync for raid1 and raid10 personalities. In case of raid5 personality
such condition is already present (at raid5.c:6029).
Bug was introduced in 3.10 and causes data corruption.

Use the driver calculated CTS and N values rather than
having hardware generate them. This allows us to use
the modeline pixel clock rather than the actual pll clock
when setting up the dto for audio. Fixes problems with
audio playback rate on certain asics if the pll clock
does not match the pixel clock exactly.

Sujit has found a race condition that would make q->nr_pending
unbalanced, it occurs as Sujit explained:
"
sd_probe_async() ->
add_disk() ->
disk_add_event() ->
schedule(disk_events_workfn)
sd_revalidate_disk()
blk_pm_runtime_init()
return;
Let's say the disk_events_workfn() calls sd_check_events() which tries
to send test_unit_ready() and because of sd_revalidate_disk() trying to
send another commands the test_unit_ready() might be re-queued as the
tagged command queuing is disabled.
So the race condition is -
Thread 1 | Thread 2
sd_revalidate_disk() | sd_check_events()
...nr_pending = 0 as q->dev = NULL| scsi_queue_insert()
blk_runtime_pm_init() | blk_pm_requeue_request() ->
| nr_pending = -1 since
| q->dev != NULL
"
The problem is, the test_unit_ready request doesn't get counted the
first time it is queued, so the later decrement of q->nr_pending in
blk_pm_requeue_request makes it unbalanced.
Fix this by calling blk_pm_runtime_init before add_disk so that all
requests initiated there will all be counted.

If an invalid IOCB is returned on the response queue then the index into the
request queue map could be invalid and could return to us a bogus value. This
could cause us to try to deference an invalid pointer and cause an exception.
If we encounter this condition, simply return as no context can be established
for this response.

The result of the store-clock-fast (STCKF) instruction is a bit fuzzy.
It can happen that the value stored on one CPU is smaller than the value
stored on another CPU, although the order of the stores is the other
way around. This can cause deltas of get_tod_clock() values to become
negative when they should not be.
We need to be more careful with store-clock-fast, this patch partially
reverts git commit e4b7b4238e666682555461fa52eecd74652f36bb "time:
always use stckf instead of stck if available". The get_tod_clock()
function now uses the store-clock-extended (STCKE) instruction.
get_tod_clock_fast() can be used if the fuzziness of store-clock-fast
is acceptable e.g. for wait loops local to a CPU.

This patch addresses Bug 60727
(https://bugzilla.kernel.org/show_bug.cgi?id=60727)
which was due to the truncation of intermediate values in the
calculations, which causes the code to consistently underestimate the
current cpu frequency, specifically 100% cpu utilization was truncated
down to the setpoint of 97%. This patch fixes the problem by keeping
the results of all intermediate calculations as fixed point numbers
rather scaling them back and forth between integers and fixed point.

When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
emac_dev_mcast_set should only enable RX of multicasts and reset
MACHASH registers.
It does this, but afterwards it either sets up multicast MACs
filtering or disables RX of multicasts and resets MACHASH registers
again, rendering IFF_ALLMULTI flag useless.
This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

As part of a register dump, the interface pretends to have the identity
of other interfaces of the same physical device in order to perform
HW configuration for them - specifically, it needs to prevent attentions
from generating on those functions as the register dump accesses registers
in common blocks which whose reading might generate an attention.
However, such pretension is unsafe - unlike other flows in which the driver
uses pretend, during register dump there is no guarantee no other HW access
will take place (by other flows). If such access will take place, the HW will
be accessed by the wrong interface, and leave both functions in an incorrect
state.
This patch removes all pretensions from the register dump flow. Instead, it
changes initial configuration of attentions such that no fatal attention will
be generated for other functions as a result of the register dump
(notice however, a debug print claiming an attention from other functions IS
possible during the register dump)

bnx2x has several clients to its DMAE machines - all of them with the exception
of the statistics flow used the same locking mechanisms to synchronize the DMAE
machines' usage.
Since statistics (which are periodically entered) use DMAE without taking the
locks, they may erase the commands which were previously set -
e.g., it may cause a VF to timeout while waiting for a PF answer on the VF-PF
channel as that command header would have been overwritten by the statistics'
header.
This patch makes certain that all flows utilizing DMAE will use the same
API, assuring that the locking scheme will be kept by all said flows.

During a panic, the driver tries to print the Management FW buffer of recent
commands. To do so, the driver reads the address of that buffer from a known
address. If the buffer is unavailable (e.g., PCI reads don't work, MCP is
failing, etc.), the driver will try to access the address it has read, possibly
causing a kernel panic.
This check 'sanitizes' the access, validating the read value is indeed a valid
address inside the management FW's buffers.
The patch also removes a read outside the scope of the buffer, which resulted
in some unrelated chraracters appearing in the log.

Daniel pointed out that it was hard to get anything lockless to work
correctly, so don't even try for this non critical piece of code and
just use a spin lock.
v2: Make intel_pipe_crc->opened a bool
v3: Use assert_spin_locked() instead of a comment (Daniel Vetter)
v4: Use spin_lock_irq() in the debugfs functions (they can only be
called from process context),
Use spin_lock() in the pipe_crc_update() function that can only be
called from an interrupt handler,
Use wait_event_interruptible_lock_irq() when waiting for data in the
cicular buffer to ensure proper locking around the condition we are
waiting for. (Daniel Vetter)

When interrupt pacing is enabled, receive/transmit statistics are not

So far the modeset code enabled all power domains if it needed any. It
wasn't a problem since HW generations so far only had one always-on
power well and one dynamic power well that can be enabled/disabled. For
domains powered by always-on power wells (panel fitter on pipe A and the
eDP transcoder) we didn't do anything, for all other domains we just
enabled the single dynamic power well.
Future HW generations will change this, as they add multiple dynamic
power wells. Support for these will be added later, this patch prepares
for those by making sure we only enable the required domains.
Note that after this change on HSW we'll enable all power domains even
if it was the domain for the panel fitter on pipe A or the eDP
transcoder. This isn't a problem since the power domain framework
already checks if the domain is on an always-on power well and doesn't
do anything in this case.
