Communications with a hardware vendor confirm that the expected behaviour
on systems that set the FADT ASPM disable bit but which still grant full
PCIe control is for the OS to leave any BIOS configuration intact and
refuse to touch the ASPM bits. This mimics the behaviour of Windows.

handle_offloads() calls skb_reset_inner_headers() to store
the layer pointers to the encapsulated packet. However, we
currently push the vlag tag (if there is one) onto the packet
afterwards. This changes the MAC header for the encapsulated
packet but it is not reflected in skb->inner_mac_header, which
breaks GSO and drivers which attempt to use this for encapsulation
offloads.
Fixes: 1eaa8178 ("vxlan: Add tx-vlan offload support.")

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next tree.
They are:
* nf_tables set timeout infrastructure from Patrick Mchardy.
1) Add support for set timeout support.
2) Add support for set element timeouts using the new set extension
infrastructure.
4) Add garbage collection helper functions to get rid of stale elements.
Elements are accumulated in a batch that are asynchronously released
via RCU when the batch is full.
5) Add garbage collection synchronization helpers. This introduces a new
element busy bit to address concurrent access from the netlink API and the
garbage collector.
5) Add timeout support for the nft_hash set implementation. The garbage
collector peridically checks for stale elements from the workqueue.
* iptables/nftables cgroup fixes:
6) Ignore non full-socket objects from the input path, otherwise cgroup
match may crash, from Daniel Borkmann.
7) Fix cgroup in nf_tables.
8) Save some cycles from xt_socket by skipping packet header parsing when
skb->sk is already set because of early demux. Also from Daniel.
* br_netfilter updates from Florian Westphal.
9) Save frag_max_size and restore it from the forward path too.
10) Use a per-cpu area to restore the original source MAC address when traffic
is DNAT'ed.
11) Add helper functions to access physical devices.
12) Use these new physdev helper function from xt_physdev.
13) Add another nf_bridge_info_get() helper function to fetch the br_netfilter
state information.
14) Annotate original layer 2 protocol number in nf_bridge info, instead of
using kludgy flags.
15) Also annotate the pkttype mangling when the packet travels back and forth
from the IP to the bridge layer, instead of using a flag.
* More nf_tables set enhancement from Patrick:
16) Fix possible usage of set variant that doesn't support timeouts.
17) Avoid spurious "set is full" errors from Netlink API when there are pending
stale elements scheduled to be released.
18) Restrict loop checks to set maps.
19) Add support for dynamic set updates from the packet path.
20) Add support to store optional user data (eg. comments) per set element.
BTW, I have also pulled net-next into nf-next to anticipate the conflict
resolution between your okfn() signature changes and Florian's br_netfilter
updates.

====================
Replace wmb()/rmb() with dma_wmb()/dma_rmb() where appropriate, round 2
More cleanup of drivers in order to start making use of dma_rmb and dma_wmb
calls. This is another pass of what I would consider to be low hanging
fruit. There may be other opportunities to make use of the barriers in the
Mellanox and Chelsio drivers but I didn't want to risk meddling with code I
was not completely familiar with so I am leaving that for future work.
I have revisited the Mellanox driver changes. This time around I went only
for the sections with a clearly defined pattern. For dma_wmb I used it
between accesses of the descriptor bits followed by owner or size. For
dma_rmb I used it to replace rmb following a read of the ownership bit in
the descriptor.

This patch should help to improve the performance of the mlx4 and mlx5 on a
number of architectures. For example, on x86 the dma_wmb/rmb equates out
to a barrer() call as the architecture is already strong ordered, and on
PowerPC the call works out to a lwsync which is significantly less expensive
than the sync call that was being used for wmb.
I placed the new barriers between any spots that seemed to be trying to
order memory/memory reads or writes, if there are any spots that involved
MMIO I left the existing wmb in place as the new barriers cannot order
transactions between coherent and non-coherent memories.
v2: Reduced the replacments to just the spots where I could clearly
identify the usage pattern.

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.

To use jump labels in assembly we need the HAVE_JUMP_LABEL
define, so we select a fallback version if the toolchain does
not support them.
Modify linux/jump_label.h so it can be included by assembly
files. We also need to add -DCC_HAVE_ASM_GOTO to KBUILD_AFLAGS.

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef
__KERNEL__ so can simplify things a bit.
If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

Currently it is not possible to use 'mmc-pwrseq-simple' property with this
driver because mmc_of_parse() is never called.
mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence and
allows passing GPIOs in the devicetree to properly power/reset the Wifi
chipset.
When using mmc_of_parse() we no longer need to have custom code to request
card-detect and write-protect pins, as this can now be handled by the mmc
core.
Tested on a imx6sl-warp board where BT/Wifi is functional and also on a
imx6q-sabresd.

It is possible for the cmd11 interrupt to fire and delete the
cmd11_timer before the cmd11_timer was actually setup. Let's fix this
race by adding a few spinlocks. Note that the race wasn't seen in
practice without adding some printk statements, but it still seems
wise to fix.
