tps6105 driver provides two cells. One is for GPIO and another one is
for selected mode depending on platform data. When tps6105x is used in
GPIO-only mode, this driver calls mfd_add_devices() with mfd_cell
.name == NULL. This value causes an oops in platform_device_register()
later.
The following patch adds a mfd_cell for each possible mode thereby
excluding .name assignment in runtime.

The R-Car PCIe host controller driver uses pci_common_init_dev(), which is
ARM-specific and requires the ARM struct hw_pci. The part of
pci_common_init_dev() that is needed is limited and can be done here
without using hw_pci.
Note that the ARM pcibios functions expect the PCI sysdata to be a pointer
to a struct pci_sys_data. Add a struct pci_sys_data as the first element
in struct gen_pci so that when we use a gen_pci pointer as sysdata, it is
also a pointer to a struct pci_sys_data.
Create and scan the root bus directly without using the ARM
pci_common_init_dev() interface.

1) The flow cache is limited by the flow cache limit which
depends on the number of cpus and the xfrm garbage collector
threshold which is independent of the number of cpus. This
leads to the fact that on systems with more than 16 cpus
we hit the xfrm garbage collector limit and refuse new
allocations, so new flows are dropped. On systems with 16
or less cpus, we hit the flowcache limit. In this case, we
shrink the flow cache instead of refusing new flows.
We increase the xfrm garbage collector threshold to INT_MAX
to get the same behaviour, independent of the number of cpus.
2) Fix some unaligned accesses on sparc systems.
From Sowmini Varadhan.
3) Fix some header checks in _decode_session4. We may call
pskb_may_pull with a negative value converted to unsigened
int from pskb_may_pull. This can lead to incorrect policy
lookups. We fix this by a check of the data pointer position
before we call pskb_may_pull.
4) Reload skb header pointers after calling pskb_may_pull
in _decode_session4 as this may change the pointers into
the packet.
5) Add a missing statistic counter on inner mode errors.
Please pull or let me know if there are problems.

It's a bit bigger than usual, the 3 main culprits being:
- A new driver for Intel's Fields Peak NCI chipset. In order to
support this chipset we had to export a few NCI routines and
extend the driver NCI ops to not only support proprietary
commands but also core ones.
- Support for vendor commands for both STM drivers, st-nci
and st21nfca. Those vendor commands allow to run factory tests
through the NFC netlink interface.
- New i2c and SPI support for the Marvell driver, together with
firmware download support for this driver's core.
Besides that we also have:
- A few file renames in the STM drivers, to keep the naming
consistent between drivers.
- Some improvements and fixes on the NCI HCI layer, mostly to
properly reach a secure element over a legacy HCI link.
- A few fixes for the s3fwrn5 and trf7970a drivers.
