[ Upstream commit c8931ef55bd325052ec496f242aea7f6de47dc9c ]
Struct uvc_frame and interval (u32*) are packaged together on
streaming->formats on a single contiguous allocation.
Right now they are allocated right after uvc_format, without taking into
consideration their required alignment.
This is working fine because both structures have a field with a
pointer, but it will stop working when the sizeof() of any of those
structs is not a multiple of the sizeof(void*).
Enforce that alignment during the allocation.

isn't clear how that happens, nor have I been able to reproduce it,
but if it does happen, the kernel crashes later, when it tries to
unhash the entry that's now not hashed.
Try to make this situation more survivable by removing the BSS from
the list(s) as well, that way it's fully leaked here (as had been
the intent in the hash insert error path), and no longer reachable
through the list(s) so it shouldn't be unhashed again later.

Check the return value of amd_smn_read() before saving a value. This
ensures invalid values aren't saved or used.
There are three cases here with slightly different behavior:
1) read_tempreg_nb_zen():
This is a function pointer which does not include a return code.
In this case, set the register value to 0 on failure. This
enforces Read-as-Zero behavior.
2) k10temp_read_temp():
This function does have return codes, so return the error code
from the failed register read. Continued operation is not
necessary, since there is no valid data from the register.
Furthermore, if the register value was set to 0, then the
following operation would underflow.
3) k10temp_get_ccd_support():
This function reads the same register from multiple CCD
instances in a loop. And a bitmask is formed if a specific bit
is set in each register instance. The loop should continue on a
failed register read, skipping the bit check.

[ Upstream commit 2fe209d0ad2e2729f7e22b9b31a86cc3ff0db550 ]
Currently, Smack mirrors the label of incoming tcp/ipv4 connections:
when a label 'foo' connects to a label 'bar' with tcp/ipv4,
'foo' always gets 'foo' in returned ipv4 packets. So,
1) returned packets are incorrectly labeled ('foo' instead of 'bar')
2) 'bar' can write to 'foo' without being authorized to write.
Here is a scenario how to see this:
* Take two machines, let's call them C and S,
with active Smack in the default state
(no settings, no rules, no labeled hosts, only builtin labels)
* At S, add Smack rule 'foo bar w'
(labels 'foo' and 'bar' are instantiated at S at this moment)
* At S, at label 'bar', launch a program
that listens for incoming tcp/ipv4 connections
* From C, at label 'foo', connect to the listener at S.
(label 'foo' is instantiated at C at this moment)
Connection succeedes and works.
* Send some data in both directions.
* Collect network traffic of this connection.
All packets in both directions are labeled with the CIPSO
of the label 'foo'. Hence, label 'bar' writes to 'foo' without
being authorized, and even without ever being known at C.
If anybody cares: exactly the same happens with DCCP.
This behavior 1st manifested in release 2.6.29.4 (see Fixes below)
and it looks unintentional. At least, no explanation was provided.
I changed returned packes label into the 'bar',
to bring it into line with the Smack documentation claims.

In some setups directories can have many (usually negative) dentries.
Hence __fsnotify_update_child_dentry_flags() function can take a
significant amount of time. Since the bulk of this function happens
under inode->i_lock this causes a significant contention on the lock
when we remove the watch from the directory as the
__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()
races with __fsnotify_update_child_dentry_flags() calls from
__fsnotify_parent() happening on children. This can lead upto softlockup
reports reported by users.
Fix the problem by calling fsnotify_update_children_dentry_flags() to
set PARENT_WATCHED flags only when parent starts watching children.
When parent stops watching children, clear false positive PARENT_WATCHED
flags lazily in __fsnotify_parent() for each accessed child.

The bypass lock contention mitigation assumes there can be at most
2 contenders on the bypass lock, following this scheme:
1) One kthread takes the bypass lock
2) Another one spins on it and increment the contended counter
3) A third one (a bypass enqueuer) sees the contended counter on and
busy loops waiting on it to decrement.
However this assumption is wrong. There can be only one CPU to find the
lock contended because call_rcu() (the bypass enqueuer) is the only
bypass lock acquire site that may not already hold the NOCB lock
beforehand, all the other sites must first contend on the NOCB lock.
Therefore step 2) is impossible.
The other problem is that the mitigation assumes that contenders all
belong to the same rdp CPU, which is also impossible for a raw spinlock.
In theory the warning could trigger if the enqueuer holds the bypass
lock and another CPU flushes the bypass queue concurrently but this is
prevented from all flush users:
1) NOCB kthreads only flush if they successfully _tried_ to lock the
bypass lock. So no contention management here.
2) Flush on callbacks migration happen remotely when the CPU is offline.
No concurrency against bypass enqueue.
3) Flush on deoffloading happen either locally with IRQs disabled or
remotely when the CPU is not yet online. No concurrency against
bypass enqueue.
4) Flush on barrier entrain happen either locally with IRQs disabled or
remotely when the CPU is offline. No concurrency against
bypass enqueue.
For those reasons, the bypass lock contention mitigation isn't needed
and is even wrong. Remove it but keep the warning reporting a contended
bypass lock on a remote CPU, to keep unexpected contention awareness.

This timer HW supports 8, 16 and 32-bit timer widths. This
driver currently uses a u32 to store the max possible value
of the timer. However, statements perform addition of 2 in
xilinx_pwm_apply() when calculating the period_cycles and
duty_cycles values. Since priv->max is a u32, this will
result in an overflow to 1 which will not only be incorrect
but fail on range comparison. This results in making it
impossible to set the PWM in this timer mode.
There are two obvious solutions to the current problem:
1. Cast each instance where overflow occurs to u64.
2. Change priv->max from a u32 to a u64.
Solution #1 requires more code modifications, and leaves
opportunity to introduce similar overflows if other math
statements are added in the future. These may also go
undetected if running in non 32-bit timer modes.
Solution #2 is the much smaller and cleaner approach and
thus the chosen method in this patch.
This was tested on a Zynq UltraScale+ with multiple
instances of the PWM IP.
