not linked with libtraceevent
When we have a perf.data file with tracepoints, such as:
# perf evlist -f
probe_perf:lzma_decompress_to_file
# Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
#
We end up segfaulting when using perf built with NO_LIBTRACEEVENT=1 by
trying to find an evsel with a NULL 'event_name' variable:
(gdb) run report --stdio -f
Starting program: /root/bin/perf report --stdio -f
Program received signal SIGSEGV, Segmentation fault.

If v4 READDIR operation hits a mountpoint and gets back an error,
then it will include that entry in the reply and set RDATTR_ERROR for it
to the error.
That's fine for "normal" exported filesystems, but on the v4root, we
need to be more careful to only expose the existence of dentries that
lead to exports.
If the mountd upcall times out while checking to see whether a
mountpoint on the v4root is exported, then we have no recourse other
than to fail the whole operation.

ipu_src_rect_width() was introduced to support odd screen resolutions
such as 1366x768 by internally rounding up primary plane width to a
multiple of 8 and compensating with reduced horizontal blanking.
This also caused overlay plane width to be rounded up, which was not
intended. Fix overlay plane width by limiting the rounding up to the
primary plane.
drm_rect_width(&new_state->src) >> 16 is the same value as
drm_rect_width(dst) because there is no plane scaling support.

Commit 62d89a7d49af ("video: fbdev: matroxfb: set maxvram of vbG200eW to
the same as vbG200 to avoid black screen") accidently decreases the
maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB
by missing one zero. This caused the driver initialization to fail with
the messages below, as the minimum required VRAM size is 2 MB:
[ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected
[ 9.444502] matroxfb: cannot determine memory size
[ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1
So, add the missing 0 to make it the intended 16 MB. Successfully tested on
the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is
gone.
While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned
properly. The value could probably also be increased from 8 MB to 16 MB, as
the G200 uses the same values, but I have not checked any datasheet.
Note, matroxfb is obsolete and superseded by the maintained DRM driver
mga200, which is used by default on most systems where both drivers are
available. Therefore, on most systems it was only a cosmetic issue.

The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy()
while userspace process is exiting or being killed. First time it's invoked
when sched entity is flushed and second time when entity is released. This
causes a lockup within wait_for_completion(entity_idle) due to how completion
API works.
Calling wait_for_completion() more times than complete() was invoked is a
error condition that causes lockup because completion internally uses
counter for complete/wait calls. The complete_all() must be used instead
in such cases.
This patch fixes lockup of Panfrost driver that is reproducible by killing
any application in a middle of 3d drawing operation.

When adding/deleting large number of elements in one step in ipset, it can
take a reasonable amount of time and can result in soft lockup errors. The
patch 5f7b51bf09ba ("netfilter: ipset: Limit the maximal range of
consecutive elements to add/delete") tried to fix it by limiting the max
elements to process at all. However it was not enough, it is still possible
that we get hung tasks. Lowering the limit is not reasonable, so the
approach in this patch is as follows: rely on the method used at resizing
sets and save the state when we reach a smaller internal batch limit,
unlock/lock and proceed from the saved state. Thus we can avoid long
continuous tasks and at the same time removed the limit to add/delete large
number of elements in one step.
The nfnl mutex is held during the whole operation which prevents one to
issue other ipset commands in parallel.

There is an issue with the checking of the return value of
'of_get_mac_address', which returns 0 on success and negative value on
failure. The driver interpretated the result the opposite way. Therefore
if there was a MAC address defined in the DT, then the driver was
generating a random MAC address otherwise it would use address 0.
Fix this by checking correctly the return value of 'of_get_mac_address'

Jamal Hadi Salim says:
====================
net: dont intepret cls results when asked to drop
It is possible that an error in processing may occur in tcf_classify() which
will result in res.classid being some garbage value. Example of such a code path
is when the classifier goes into a loop due to bad policy. See patch 1/2
for a sample splat.
While the core code reacts correctly and asks the caller to drop the packet
(by returning TC_ACT_SHOT) some callers first intepret the res.class as
a pointer to memory and end up dropping the packet only after some activity with
the pointer. There is likelihood of this resulting in an exploit. So lets fix
all the known qdiscs that behave this way.

If asked to drop a packet via TC_ACT_SHOT it is unsafe to assume that

When ceph releasing the file_lock it will try to get the inode pointer
from the fl->fl_file, which the memory could already be released by
another thread in filp_close(). Because in VFS layer the fl->fl_file
doesn't increase the file's reference counter.
Will switch to use ceph dedicate lock info to track the inode.
And in ceph_fl_release_lock() we should skip all the operations if the
fl->fl_u.ceph.inode is not set, which should come from the request
file_lock. And we will set fl->fl_u.ceph.inode when inserting it to the

For the POSIX locks they are using the same owner, which is the
thread id. And multiple POSIX locks could be merged into single one,
so when checking whether the 'file' has locks may fail.
For a file where some openers use locking and others don't is a
really odd usage pattern though. Locks are like stoplights -- they
only work if everyone pays attention to them.
Just switch ceph_get_caps() to check whether any locks are set on
the inode. If there are POSIX/OFD/FLOCK locks on the file at the
time, we should set CHECK_FILELOCK, regardless of what fd was used
to set the lock.

commit 9f93ac8d4085 ("net-next: stmmac: Add dwmac-sun8i"). In fact, the
original driver submission includes the phy-supply code but no mention
of it in the binding, so the omission appears to be accidental. In
addition, the property is documented in the binding for the previous
hardware generation, allwinner,sun7i-a20-gmac.

First 2 patch fix mgmt eth where the lenght calculation is very
confusing and in step of word size. (the related commit description have
an extensive description about how this mess works)
Last 3 patch revert the broken mdio cache and apply a correct version
that should still save some extra mdio in phy poll secnario.

Improve mdio master read/write by using singe mii read/write lo/hi.
In a read and write we need to poll the mdio master regs in a busy loop
to check for a specific bit present in the upper half of the reg. We can
ignore the other half since it won't contain useful data. This will save
an additional useless read for each read and write operation.
In a read operation the returned data is present in the mdio master reg
lower half. We can ignore the other half since it won't contain useful
data. This will save an additional useless read for each read operation.
In a read operation it's needed to just set the hi half of the mdio
master reg as the lo half will be replaced by the result. This will save
an additional useless write for each read operation.

It may be useful to read/write just the lo or hi half of a reg.
This is especially useful for phy poll with the use of mdio master.
The mdio master reg is composed by the first 16 bit related to setup and
the other half with the returned data or data to write.
Refactor the mii function to permit single mii read/write of lo or hi
half of the reg.

This reverts commit 2481d206fae7884cd07014fd1318e63af35e99eb.
The Documentation is very confusing about the topic.
The cache logic for hi and lo is wrong and actually miss some regs to be
actually written.
What the Documentation actually intended was that it's possible to skip
writing hi OR lo if half of the reg is not needed to be written or read.
Revert the change in favor of a better and correct implementation.

The assumption that Documentation was right about how this value work was
wrong. It was discovered that the length value of the mgmt header is in
step of word size.
As an example to process 4 byte of data the correct length to set is 2.
To process 8 byte 4, 12 byte 6, 16 byte 8...
Odd values will always return the next size on the ack packet.
(length of 3 (6 byte) will always return 8 bytes of data)
This means that a value of 15 (0xf) actually means reading/writing 32 bytes
of data instead of 16 bytes. This behaviour is totally absent and not
documented in the switch Documentation.
In fact from Documentation the max value that mgmt eth can process is
16 byte of data while in reality it can process 32 bytes at once.
To handle this we always round up the length after deviding it for word
size. We check if the result is odd and we round another time to align
to what the switch will provide in the ack packet.
The workaround for the length limit of 15 is still needed as the length
reg max value is 0xf(15)

Currently, when mlx5_ib_get_hw_stats() is used for device (port_num = 0),
there is a special handling in order to use the correct counters, but,
port_num is being passed down the stack without any change. Also, some
functions assume that port_num >=1. As a result, the following oops can
occur.
