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.

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.
Fix this by using consistent RTC alarm interrupt numbers and adding a
BUILD_BUG_ON for future generations.

The Synopsys DesignWare DWAPB GPIO block is popular to
synthesize amongst many architectures: X86, ARM, ARC.
The driver was restricted to only these archs due to
using [read|write]l_relaxed() accessors that were not
universally available in the past,
but as of commit 9439eb3ab9d1ece6e4ad7baaa4a7f534f9b9dab0
"asm-generic: io: implement relaxed accessor macros as
conditional wrappers" these accessors are available on all
archs so this should not be a problem any more. Enable the
driver for all archs.

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.

Although the cmd11 interrupt should come within 2ms, that's a very
short time. Let's increase the timeout to be really sure that we
don't get an accidnetal timeout. One case in particular this is
useful is if you've got a serial console and printk in just the right
places. Under that scenario I've seen delays of up to 130ms before
the interrupt fired.
CMD11 is only sent during card insertion, so this extra timeout
shouldn't be terrible.

The dw_mmc driver changes to make the IO accesors endian agnostic did not
take into account the fifo accesses do not need to be swapped. To fix this
add a mmci_fifo_read/write wrapper to allow these to be passed through the
IO without being swapped.
Since these are now specific functions, it would be easier just to store
the pointer to the fifo registers in the host block instead of the offset
to them. So change the host->data_offset to host->fifo_reg (which also
means we catch all the places this is read or written).

Thermal framework may already be ready and cooling policies might
already be functional when we are attempting to register gpio fan as
a cooling device. This can be reproduced by changing probe order in
which registration of various modules are done in a system. In such
a case, kernel generates an oops since the data structures are not
completely populated with the wrong assumption that thermal framework
is not yet ready. Fix this by reordering the thermal framework
registration to occur after hwmon registration of the fan is complete.

The numPosted field in the ERX Doorbell register is 8-bits wide.
So the max buffers that we can post at a time is 255 and not 256
which we are doing currently.

The PCI "ACPI additions for FW latency optimizations" ECN (link below)
defines two functions in the PCI _DSM:
Function 8, "Reset Delay," applies to the entire hierarchy below a PCI
host bridge. If it returns one, the OS may assume that all devices in
the hierarchy have already completed power-on reset delays.
Function 9, "Device Readiness Durations," applies only to the object
where it is located. It returns delay durations required after various
events if the device requires less time than the spec requires. Delays
from this function take precedence over the Reset Delay function.
Add support for Reset Delay and part of Device Readiness Durations.

====================
NFC: 4.1 pull request
This is the NFC pull request for 4.1.
This is a shorter one than usual, as the Intel Field Peak NFC
driver could not make it in time.
We have:
- A new driver for NXP NCI based chipsets, like e.g. the NPC100 or
the PN7150. It currently only supports an i2c physical layer, but
could easily be extended to work on top of e.g. SPI.
This driver also includes support for user space triggered firmware
updates.
- A few minor st21nfc[ab] fixes, cleanups, and comments improvements.
- A pn533 error return fix.
- A few NFC related logs formatting cleanups.
