hu->proto->*speed will always be used for all device where it is set.
But hu->*speed should be used if exist, so the test should be swapped.
The equivalent change is needed in bcm_setup() of hci_bcm.c.

Let's force a 16 bytes alignment on xt_counter percpu allocations,
so that bytes and packets sit in same cache line.
xt_counter being exported to user space, we cannot add __align(16) on

xt_socket is useful for matching sockets with IP_TRANSPARENT and
taking some action on the matching packets. However, it lacks the
ability to match only a small subset of transparent sockets.
Suppose there are 2 applications, each with its own set of transparent
sockets. The first application wants all matching packets dropped,
while the second application wants them forwarded somewhere else.
Add the ability to retore the skb->mark from the sk_mark. The mark
is only restored if a matching socket is found and the transparent /
nowildcard conditions are satisfied.
Now the 2 hypothetical applications can differentiate their sockets
based on a mark value set with SO_MARK.
iptables -t mangle -I PREROUTING -m socket --transparent \
--restore-skmark -j action
iptables -t mangle -A action -m mark --mark 10 -j action2
iptables -t mangle -A action -m mark --mark 11 -j action3

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
This series contains updates to fm10k only.
Alex provides two fixes for the fm10k, first folds the fm10k_pull_tail()
call into fm10k_add_rx_frag(), this way the fragment does not have to be
modified after it is added to the skb. The second fixes missing braces
to an if statement.
The remaining patches are from Jacob which contain improvements and fixes
for fm10k. First fix makes it so that invalid address will simply be
skipped and allows synchronizing the full list to proceed with using
iproute2 tool. Fixed a possible kernel panic by using the correct
transmit timestamp function. Simplified the code flow for setting the
IN_PROGRESS bit of the shinfo for an skb that we will be timestamping.
Fix a bug in the timestamping transmit enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list by freeing
the clone in the cases where we did not add it to the queue. Update the
PF code so that it resets the empty TQMAP/RQMAP regirsters post-VFLR to
prevent innocent VF drivers from triggering malicious driver events.
The SYSTIME_CFG.Adjust direction bit is actually supposed to indicate
that the adjustment is positive, so fix the code to align correctly with
the hardware and documentation. Cleanup local variable that is no longer
used after a previous refactor of the code. Fix the code flow so that we
actually clear the enabled flag as part of our removal of the LPORT.
v2:
- updated patch 07 description based on feedback from Sergei Shtylyov
- updated patch 09 & 10 to use %d in error message based on feedback

After the ->set() spinlocks were removed br_stp_set_bridge_priority
was left running without any protection when used via sysfs. It can
race with port add/del and could result in use-after-free cases and
corrupted lists. Tested by running port add/del in a loop with stp
enabled while setting priority in a loop, crashes are easily
reproducible.
The spinlocks around sysfs ->set() were removed in commit:
14f98f258f19 ("bridge: range check STP parameters")
There's also a race condition in the netlink priority support that is
fixed by this change, but it was introduced recently and the fixes tag
covers it, just in case it's needed the commit is:

We are burrying direct access to MTRR code support on
x86 in order to take advantage of PAT. In the future, we
also want to make the default behaviour of ioremap_nocache()
to use strong UC, use of mtrr_add() on those systems
would make write-combining void.
In order to help both enable us to later make strong
UC default and in order to phase out direct MTRR access
code port the driver over to arch_phys_wc_add() and
annotate that the device driver requires systems to
boot with PAT disabled, with the 'nopat' kernel parameter.
This is a workable compromise given that the ipath device
driver powers the old HTX bus cards that only work in
AMD systems, while the newer IB/qib device driver
powers all PCI-e cards. The ipath device driver is
obsolete, hardware is hard to find and because of this
its a reasonable compromise to require users of ipath
to boot with 'nopat'.

Instead of having a single 'input_dev' device that will take either pen
or touch data depending on the type of the device, create seperate devices
devices for each. By splitting things like this, we can support devices
(e.g. the I2C "AES" sensors in some newer tablet PCs) that send both pen
and touch reports from a single endpoint.

Historically, both the touch and pad tools would have shared the
'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you
had to use some other bit of knowledge (e.g. that the pad was on the same
interface as the pen, and thus 'touch_max' would be zero).
To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD.
Although we still have to rely on other bits of knowledge to set this
bit on the right interface (since it cannot be detected from the HID
descriptor), it can be done just once inside 'wacom_setup_device_quirks'.
This patch introduces no functional changes.

The USB devices that this driver has historically supported segregate the
pen and touch portions of the tablet. Oftentimes the segregation would be
done at the interface level, though on occasion (e.g. Cintiq 24HDT) the
tablet would combine two totally independent USB devices behind an internal
USB hub. Because pen and touch never shared the same interface, it made
sense for the 'device_type' to store a single value: "pen" or "touch".
Recently, however, some I2C devices have been created which combine the
two. A first step to accomodating this is to expand 'device_type' so that
it can represent two (or potentially more) types simultaneously. To do
this, we treat it as a bitfield and set/check individual bits rather
than using the '=' and '==' operators.
This should not result in any functional change since no supported devices
(that I'm aware of, at least) have HID descriptors that indicate both
pen and touch reports on a single interface.

The fix in d151832650ed9 (time: Move clock_was_set_seq update
before updating shadow-timekeeper) was unfortunately incomplete.
The main gist of that change was to do the shadow-copy update
last, so that any state changes were properly duplicated, and
we wouldn't accidentally have stale data in the shadow.
Unfortunately in the main update_wall_time() logic, we update
use the shadow-timekeeper to calculate the next update values,
then while holding the lock, copy the shadow-timekeeper over,
then call timekeeping_update() to do some additional
bookkeeping, (skipping the shadow mirror). The bug with this is
the additional bookkeeping isn't all read-only, and some
changes timkeeper state. Thus we might then overwrite this state
change on the next update.
To avoid this problem, do the timekeeping_update() on the
shadow-timekeeper prior to copying the full state over to
the real-timekeeper.
This avoids problems with both the clock_was_set_seq and
next_leap_ktime being overwritten and possibly the
fast-timekeepers as well.
Many thanks to Prarit for his rigorous testing, which discovered
this problem, along with Prarit and Daniel's work validating this
fix.

CLOCK_EVT_MODE_* macros are present for backward compatibility (as most
of the drivers are still using old ->set_mode() interface).
These macro's shouldn't be used anymore in code, that is common to both
driver interfaces, i.e. ->set_mode() and ->set_state_*().
Drivers implementing ->set_state_*() interface, which have their
clkevt->mode set to 0 (clkevt device structures are normally globally
defined), will not participate in suspend/resume as they will always be
marked as UNUSED.
Fix this by checking state of the clockevent device instead of mode,
which is updated for both the interfaces.

Pull tracing filter fix from Steven Rostedt:
"Vince Weaver reported a warning when he added perf event filters into
his fuzzer tests. There's a missing check of balanced operations when
parenthesis are used, and this triggers a WARN_ON() and when reading
the failure, the filter reports no failure occurred.
The operands were not being checked if they match, this adds that"

Since when we start discussions about the usage Media Controller for
complex hardware, one thing become clear: the way it is, MC fails to
map anything different than capture/output/m2m video-only streaming.
The point is that MC has entities named as devnodes, but the only
devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L.
Due to the way MC got implemented, however, this entity actually
doesn't represent the devnode, but the hardware I/O engine that
receives data via DMA.
By coincidence, such DMA is associated with the V4L device node
on webcam hardware, but this is not true even for other V4L2
devices. For example, on USB hardware, the DMA is done via the
USB controller. The data passes though a in-kernel filter that
strips off the URB headers. Other V4L2 devices like radio may not
even have DMA. When it have, the DMA is done via ALSA, and not
via the V4L devnode.
In other words, MC is broken as a whole, but tagging it as BROKEN
right now would do more harm than good.
So, instead, let's mark, for now, the DVB part as broken and
block all new changes to MC while we fix this mess, whith
we hopefully will do for the next Kernel version.

This patch fixes a number of problems in crypto driver Kconfig
entries:
1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internal
and should not be used outside of the crypto API itself.
2. Do not select ALGAPI unless you use a legacy type like
CRYPTO_ALG_TYPE_CIPHER.
3. Select the algorithm type that you are implementing, e.g., AEAD.
4. Do not select generic C code such as CBC/ECB unless you use them
as a fallback.
5. Remove default n since that is the default default.

The patch
crypto: caam - Add definition of rd/wr_reg64 for little endian platform
added support for little endian platforms to the CAAM driver. Namely a
write and read function for 64 bit registers.
The only user of this functions is the Job Ring driver (drivers/crypto/caam/jr.c).
It uses the functions to set the DMA addresses for the input/output rings.
However, at least in the default configuration, the least significant 32 bits are
always in the base+0x0004 address; independent of the endianness of the bytes itself.
That means the addresses do not change with the system endianness.
DMA addresses are only 32 bits wide on non-64-bit systems, writing the upper 32 bits
of this value to the register for the least significant bits results in the DMA address
being set to 0.
Fix this by always writing the registers in the same way.

It appears that, at some point last year, XFS made directory handling
changes which bring it into lockdep conflict with shmem_zero_setup():
it is surprising that mmap() can clone an inode while holding mmap_sem,
but that has been so for many years.
Since those few lockdep traces that I've seen all implicated selinux,
I'm hoping that we can use the __shmem_file_setup(,,,S_PRIVATE) which
v3.13's commit c7277090927a ("security: shmem: implement kernel private
shmem inodes") introduced to avoid LSM checks on kernel-internal inodes:
the mmap("/dev/zero") cloned inode is indeed a kernel-internal detail.
This also covers the !CONFIG_SHMEM use of ramfs to support /dev/zero
(and MAP_SHARED|MAP_ANONYMOUS). I thought there were also drivers
which cloned inode in mmap(), but if so, I cannot locate them now.

The pciehp debug logging is overly verbose and often redundant. Almost all
of the information printed by dbg_ctrl() is also printed by the normal PCI
core enumeration code and by pcie_init().
Remove the redundant debug info.
When claiming a pciehp bridge, we print the slot characteristics, e.g.,
Slot #6 AttnBtn- AttnInd- PwrInd- PwrCtrl- MRL- Interlock- NoCompl+ LLActRep+
Add the Hot-Plug Capable and Hot-Plug Surprise bits to this information,
and print it all in the same order as lspci does.
No functional change except the message text changes.

* pci/resource:
x86/PCI: Use host bridge _CRS info on systems with >32 bit addressing
x86/PCI: Use host bridge _CRS info on Foxconn K8M890-8237A

We enable _CRS on all systems from 2008 and later. On older systems, we
ignore _CRS and assume the whole physical address space (excluding RAM and
other devices) is available for PCI devices, but on systems that support
physical address spaces larger than 4GB, it's doubtful that the area above
4GB is really available for PCI.
After d56dbf5bab8c ("PCI: Allocate 64-bit BARs above 4G when possible"), we
try to use that space above 4GB *first*, so we're more likely to put a
device there.
On Juan's Toshiba Satellite Pro U200, BIOS left the graphics, sound, 1394,
and card reader devices unassigned (but only after Windows had been
booted). Only the sound device had a 64-bit BAR, so it was the only device
placed above 4GB, and hence the only device that didn't work.
Keep _CRS enabled even on pre-2008 systems if they support physical address
space larger than 4GB.
