Padding NTBs to max size is part of the support for devices
optimizing their DMA transfers. This optimization depends on
max sized NTBs not being ZLP terminated. So we are much better
off dropping the padding if we are going to send a ZLP anyway.

Moving the call to cdc_ncm_setup() after the endpoint
setup removes the last remaining reference to ncm_parm
outside cdc_ncm_setup.
Collecting all the ncm_parm based calculations in

These fields are only used to prevent printing the same speeds
multiple times if we receive multiple identical speed notifications.
The value of these printk's is questionable, and even more so when
we filter out some of the notifications sent us by the firmware. If
we are going to print any of these, then we should print them all.
Removing little used fields is a bonus.

Too many pointers back and forth are likely to confuse developers,
creating subtle bugs whenever we forget to syncronize them all.
As a usbnet driver, we should stick with the standard struct
usbnet fields as much as possible. The netdevice is one such
field.

We can avoid the costly division for the common case where
we pad the frame to tx_max size as long as we ensure that
tx_max is either the device specified dwNtbOutMaxSize or not
a multiplum of wMaxPacketSize.
Using the preconverted 'maxpacket' field avoids converting
wMaxPacketSize to CPU endianness for every transmitted frame
And since we only will hit the one byte padding rule for short
frames, we can drop testing the skb for tailroom.
The change means that tx_max now represents the real maximum
skb size, enabling us to allocate the correct size instead of
always making room for one extra byte.

A number of devices in the wild have turned out to require ZLPs.
Even if this is a spec violation, our priority is to make any
device work as good as possible. Devices needing ZLPs will fail
to receive any full sized frame we send. On the other hand,
devices which do not need the ZLP will still work if we send
them.
This gives us no other option than sending ZLPs by default.
This will prevent devices conforming to the spec from making the
optimizations which are possible without ZLPs. Adding known
such devices to a whitelist, to avoid the possible negative
impact of the new spec violating default.

MBIM is a point-to-point protocol transporting raw IP packets
with no L2 headers. Only IPv4 and IPv6 are supported. ARP in
particular is not, which is quite logical given the lack of
L2 headers.
The driver still emulates an ethernet interface, dropping all
unsupported protocols, and avoiding neigbour resolving by
setting the IFF_NOARP flag.
The MBIM specification does not explicitly forbid IPv6 Neighbor
Discovery, and it seems the other OS support will respond to
Neighbor Solicitations on MBIM links. There are therefore
buggy devices out there, which despite the pointlessness, still
require Neighbor Discovery for IPv6 over MBIM.
This is incompatible with the IFF_NOARP flag which disables
both ARP and ND. We cannot support ARP in any case, so we
have to keep that flag. This patch implements a workaround
for the buggy devices, letting the driver respond directly
to Neighbor Solicitations from the device.
This is not optimal, but will have minimal effect on any sane
device.

e1000_tx_ring size in the idx calculation.
Emil provides a fix for ixgbevf to remove a redundant workaround related
to header split and a fix for ixgbe to resolve an issue where the MTA table
can be cleared when the interface is reset while in promisc mode.
Todd provides a fix for igb to prevent ethtool from writing to the iNVM
in i210/i211 devices. This issue was reported by Marek Vasut <marex@denx.de>.
Anton Blanchard provides a fix for ixgbe to reduce memory consumption
with larger page sizes, seen on PPC.
Don provides a cleanup in ixgbe to replace the IXGBE_DESC_UNUSED macro with
the inline function ixgbevf_desc_unused() to make the logic a bit more

tcp_flags=flags/mask
Bitwise match on TCP flags. The flags and mask are 16-bit num‐
bers written in decimal or in hexadecimal prefixed by 0x. Each
1-bit in mask requires that the corresponding bit in port must
match. Each 0-bit in mask causes the corresponding bit to be
ignored.
TCP protocol currently defines 9 flag bits, and additional 3
bits are reserved (must be transmitted as zero), see RFCs 793,
3168, and 3540. The flag bits are, numbering from the least
significant bit:
0: FIN No more data from sender.
1: SYN Synchronize sequence numbers.
2: RST Reset the connection.
3: PSH Push function.
4: ACK Acknowledgement field significant.
5: URG Urgent pointer field significant.
6: ECE ECN Echo.
7: CWR Congestion Windows Reduced.
8: NS Nonce Sum.
9-11: Reserved.

This patch uses CONFIG_PAGE_OFFSET to filter symbols which

generally for generating code purpose and can't be run at
kernel mode, so we needn't keep them in /proc/kallsyms.

symbols any more from /proc/kallsyms, this patch fixes the

When a memcg is deleted mem_cgroup_reparent_charges() moves charged
memory to the parent memcg. As of v3.11-9444-g3ea67d0 "memcg: add per
cgroup writeback pages accounting" there's bad pointer read. The goal
was to check for counter underflow. The counter is a per cpu counter
and there are two problems with the code:
(1) per cpu access function isn't used, instead a naked pointer is used
which easily causes oops.
(2) the check doesn't sum all cpus
Test:
$ cd /sys/fs/cgroup/memory
$ mkdir x
$ echo 3 > /proc/sys/vm/drop_caches
$ (echo $BASHPID >> x/tasks && exec cat) &
[1] 7154
$ grep ^mapped x/memory.stat
mapped_file 53248
$ echo 7154 > tasks
$ rmdir x
<OOPS>
The fix is to remove the check. It's currently dangerous and isn't
worth fixing it to use something expensive, such as
percpu_counter_sum(), for each reparented page. __this_cpu_read() isn't
enough to fix this because there's no guarantees of the current cpus
count. The only guarantees is that the sum of all per-cpu counter is >=
nr_pages.

sysfs_assoc_lock is an odd piece of locking. In general, whoever owns
a kobject is responsible for synchronizing sysfs operations and sysfs
proper assumes that, for example, removal won't race with any other
operation; however, this doesn't work for symlinking because an entity
performing symlink doesn't usually own the target kobject and thus has
no control over its removal.
sysfs_assoc_lock synchronizes symlink operations against kobj->sd
disassociation so that symlink code doesn't end up dereferencing
already freed sysfs_dirent by racing with removal of the target
kobject.
This is quite obscure and the generic name of the lock and lack of
comments make it difficult to understand its role. Let's rename it to
sysfs_symlink_target_lock and add comments explaining what's going on.

13c589d5b0ac6 ("sysfs: use seq_file when reading regular files")
converted regular sysfs files to use seq_file. The commit substituted
generic_file_llseek() with seq_lseek() for llseek implementation.
Before the change, all regular sysfs files were allowed to seek to any
position in [0, PAGE_SIZE] as the file size is always PAGE_SIZE and
generic_file_llseek() allows any seeking inside the range under file
size; however, seq_lseek()'s behavior is different. It traverses the
output by repeatedly invoking ->show() until it reaches the target
offset or traversal indicates EOF. As seq_files are fully dynamic and
may not end at all, it doesn't support seeking from the end
(SEEK_END).
Apparently, there are userland tools which uses SEEK_END to discover
the buffer size to use and the switch to seq_lseek() disturbs them as
SEEK_END fails with -EINVAL.
The only benefits of using seq_lseek() instead of
generic_file_llseek() are
* Early failure. If traversing to certain file position should fail,
seq_lseek() will report such failures on lseek(2) instead of the
following read/write operations.
* EOF detection. While SEEK_END is not supported, SEEK_SET/CUR +
large offset can be used to detect eof - eof at the time of the seek
anyway as the file size may change dynamically.
Both aren't necessary for sysfs or prospect kernfs users. Revert to
genefic_file_llseek() and preserve the original behavior.

The problem is that _nfs4_do_set_security_label calls rpc_call_sync()
directly which fails to do any setup of the SEQUENCE call. Have it use
nfs4_call_sync() instead which does the right thing. While we're at it
change the name of "args" to "arg" to better match the pattern in
_nfs4_do_setattr.

Johan has been conned^Wgracious in accepting the maintainership of the
USB serial drivers, especially as he's been doing all of the real work
for the past few years.
At the same time, remove a bunch of old entries for USB serial drivers
that don't make sense anymore, given that the developers are no longer
around, and individual driver maintainerships for tiny things like this
is pretty pointless.

the "HX" chip type"
This reverts commit b8bdad608213caffa081a97d2e937e5fe08c4046.
Revert all of the pl2303 changes that went into 3.12-rc1 and -rc2 as
they cause regressions on some versions of the chip. This will all be
revisited for later kernel versions when we can figure out how to handle
this in a way that does not break working devices.
