This reverts commit e958e079e254 ("dmaengine: mic_x100: add missing
spin_unlock").
The above patch is incorrect. There is nothing wrong with the original
code. The spin_lock is acquired in the "prep" functions and released
in "submit".

commit acf673a3187edf72068ee2f92f4dc47d66baed47 fixed a user triggerable free
memory scribble but in doing so replaced it with a different one that allows
the user to control the data and scribble even more.
sixpack_close is called by the tty layer in tty context. The tty context is
protected by sp_get() and sp_put(). However network layer activity via
sp_xmit() is not protected this way. We must therefore stop the queue
otherwise the user gets to dump a buffer mostly of their choice into freed
kernel pages.

Since the mipi dsi driver need to use the clock of vop to make the
calculation of Blanking. But sometimes the clock driver can not set a
accurate clock_rate for vop, get it by clk_round_rate before mode_set,
so we can get the true value.

During initialization, when creating the send descriptor queues (SDQs),
we specify the CPU egress traffic class of each SDQ. The maximum number
of classes of this type is different in the two ASICs supported by this
PCI driver.
New firmware versions check this value is set correctly, which causes
errors on the Spectrum ASIC, as its max exposed egress traffic class is
lower than 7.
Solve this by setting this field to 3, which is an acceptable value for
both ASICs.
Note that we currently do not expose the QoS capabilities of the ASICs,
so setting this to an hardcoded value is OK for now.

gcc fails to see that the use of the 'last_offset' variable
in hns_nic_reuse_page() is used correctly and issues a bogus
warning:
drivers/net/ethernet/hisilicon/hns/hns_enet.c: In function 'hns_nic_reuse_page':
drivers/net/ethernet/hisilicon/hns/hns_enet.c:541:6: warning: 'last_offset' may be used uninitialized in this function [-Wmaybe-uninitialized]
This simplifies the function to make it more obvious what is
going on to both readers and compilers, which makes the warning
go away.

When btt devices were re-worked to be child devices of regions this
routine was overlooked. It mistakenly attempts to_nd_namespace_pmem()
or to_nd_namespace_blk() conversions on btt and pfn devices. By luck to
date we have happened to be hitting valid memory leading to a uuid
miscompare, but a recent change to struct nd_namespace_common causes:

sprintf() can access memory outside of the range of the character array,
and is risky in some situations. The driver specified prop_name string
can be longer than NAME_MAX here (only an attacker will do that though)
and so blindly copying it into the character array of size NAME_MAX
isn't safe. Instead we must use snprintf() here.

Add support for journal disk hot add/remove. Mostly trival checks in md
part. The raid5 part is a little tricky. For hot-remove, we can't wait
pending write as it's called from raid5d. The wait will cause deadlock.
We simplily fail the hot-remove. A hot-remove retry can success
eventually since if journal disk is faulty all pending write will be
failed and finish. For hot-add, since an array supporting journal but
without journal disk will be marked read-only, we are safe to hot add
journal without stopping IO (should be read IO, while journal only
handles write IO).

get_seconds() API is not y2038 safe on 32 bit systems and the API
is deprecated. Replace it with calls to ktime_get_real_seconds()
API instead. Change mddev structure types to time64_t accordingly.
32 bit signed timestamps will overflow in the year 2038.
Change the user interface mdu_array_info_s structure timestamps:
ctime and utime values used in ioctls GET_ARRAY_INFO and
SET_ARRAY_INFO to unsigned int. This will extend the field to last
until the year 2106.
The long term plan is to get rid of ctime and utime values in
this structure as this information can be read from the on-disk
meta data directly.
Clamp the tim64_t timestamps to positive values with a max of U32_MAX
when returning from GET_ARRAY_INFO ioctl to accommodate above changes
in the data type of timestamps to unsigned int.
v0.90 on disk meta data uses u32 for maintaining time stamps.
So this will also last until year 2106.
Assumption is that the usage of v0.90 will be deprecated by
year 2106.
Timestamp fields in the on disk meta data for v1.0 version already
use 64 bit data types. Remove the truncation of the bits while
writing to or reading from these from the disk.

When CONFIG_LBDAF is not set, sector_t is only 32-bits wide, which
means we cannot have devices with more than 2TB, and the code that
is trying to handle compatibility support for large devices in
md version 0.90 is meaningless but also causes a compile-time warning:
drivers/md/md.c: In function 'super_90_load':
drivers/md/md.c:1029:19: warning: large integer implicitly truncated to unsigned type [-Woverflow]
drivers/md/md.c: In function 'super_90_rdev_size_change':
drivers/md/md.c:1323:17: warning: large integer implicitly truncated to unsigned type [-Woverflow]
This adds a check for CONFIG_LBDAF to avoid even getting into this
code path, and also adds an explicit cast to let the compiler know
it doesn't have to warn about the truncation.

Communication can happen through multiple threads. It is possible that
one thread steps over another threads sequence. So, we use mutexes to
protect both the send and receive sequences.
Send communication is locked through state bit, MD_CLUSTER_SEND_LOCK.
Communication is locked with bit manipulation in order to allow
"lock and hold" for the add operation. In case of an add operation,
if the lock is held, MD_CLUSTER_SEND_LOCKED_ALREADY is set.
When md_update_sb() calls metadata_update_start(), it checks
(in a single statement to avoid races), if the communication
is already locked. If yes, it merely returns zero, else it
locks the token lockresource.

Reloading of superblock must be performed under reconfig_mutex. However,
this cannot be done with md_reload_sb because it would deadlock with
the message DLM lock. So, we defer it in md_check_recovery() which is
executed by mddev->thread.
This introduces a new flag, MD_RELOAD_SB, which if set, will reload the
superblock. And good_device_nr is also added to 'struct mddev' which is
used to get the num of the good device within cluster raid.

1. check if all the bitmap lock could be get or not, if yes then
we can continue the change since cluster raid is only active
in current node. Otherwise return fail and unlock the related
bitmap locks
2. set nodes to 0 and then leave cluster environment.
3. release other nodes's bitmap lock.

For cluster raid, if one disk couldn't be reach in one node, then
other nodes would receive the REMOVE message for the disk.
In receiving node, we can't call md_kick_rdev_from_array to remove
the disk from array synchronously since the disk might still be busy
in this node. So let's set a ClusterRemove flag on the disk, then
let the thread to do the removal job eventually.

Spansion and Winbond have occasionally used the same manufacturer ID,
and they don't support the same features. Particularly, writing SR=0
seems to break read access for Spansion's s25fl064k. Unfortunately, we
don't currently have a way to differentiate these Spansion and Winbond
parts, so rather than regressing support for these Spansion flash, let's
drop the new Winbond lock/unlock support for now. We can try to address
Winbond support during the next release cycle.

Caused by commit

The flash node is already correctly assigned using the new helper

protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled. This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.
