dc9691066f pinctrl: sunxi: Move the reset handling functions out of the core
The way that reset is handled right now is that it is made optional for every
pinctrl driver, while actually, it isn't used at all for the main pin

controller.

7fd44dacdd x86, x32: Use compat shims for io_{setup,submit}
The io_setup takes a pointer to a context id of type aio_context_t.
This in turn is typed to a __kernel_ulong_t.  We could tweak the
exported headers to define this as a 64bit quantity for specific
ABIs, but since we already have a 32bit compat shim for the x86 ABI,
let's just re-use that logic.  The libaio package is also written to
expect this as a pointer type, so a compat shim would simplify that.

The io_submit func operates on an array of pointers to iocb structs.
Padding out the array to be 64bit aligned is a huge pain, so convert
it over to the existing compat shim too.

We don't convert io_getevents to the compat func as its only purpose
is to handle the timespec struct, and the x32 ABI uses 64bit times.

With this change, the libaio package can now pass its testsuite when
built for the x32 ABI.

788296b2d1 ARM: dts: kirkwood: fix mislocated pcie-controller nodes
Commit 54397d8534
 ("ARM: kirkwood: Relocate PCIe device tree nodes")

moved the pcie-controller nodes for the Kirkwood SoCs to the mbus
bus node. For some reason, two boards were not properly converted
and have their pci-controller nodes still in the ocp bus node.

As the corresponding SoC pcie-controller does not exist anymore,
it is likely that pcie is broken on those boards since above commit.
Fix it by moving the pcie related nodes to the correct location.

extra variable declaration in __skb_get_pay_offset(), the cast in

Latter was suggested by Fengguang Wu found with coccinelle. Also,
remaining pointer casts of long should be unsigned long instead.

30743837dd net: filter: make register naming more comprehensible
The current code is a bit hard to parse on which registers can be used,
how they are mapped and all play together. It makes much more sense to
define this a bit more clearly so that the code is a bit more intuitive.
This patch cleans this up, and makes naming a bit more consistent among
the code. This also allows for moving some of the defines into the header
file. Clearing of A and X registers in __sk_run_filter() do not get a
particular register name assigned as they have not an 'official' function,
but rather just result from the concrete initial mapping of old BPF
programs. Since for BPF helper functions for BPF_CALL we already use
small letters, so be consistent here as well. No functional changes.

This patch simplifies label naming for the BPF jump-table.
When we define labels via DL(), we just concatenate/textify
the combination of instruction opcode which consists of the
class, subclass, word size, target register and so on. Each
time we leave BPF_ prefix intact, so that e.g. the preprocessor
generates a label BPF_ALU_BPF_ADD_BPF_X for DL(BPF_ALU, BPF_ADD,
BPF_X) whereas a label name of ALU_ADD_X is much more easy
to grasp. Pure cleanup only.

c97ffdbf51 NFC: st21nfca: Improved i2c Rx data correctness check
A frame starts with ST21NFCA_SOF_EOF(0x7e) + 0x00.
A frame ends with ST21NFCA_SOF_EOF(0x7e).
It is possible that the i2c macrocell is stopped for other
communication interfaces with highest priority(RF or SWP).
This can be seen with some 0xFF data at the end of a received shdlc buffer.
If this happen we need to discard the frame because the CLF will repeat it.

In order to push accurate data to hci layer, we add the following fix:
- Instead of looking for the first 0x7e in the frame, check that the last
received byte is 0x7e.
- Check that the first frame reception block start with start of
frame(0x7e 0x00). If not, clear the buffer.
- Check that the next frame reception block do not start with start of
frame(0x7e). If so, clear the buffer.

e1fb97b925 NFC: st21nfca: Fix st21nfca_hci_remove_len_crc tail room handling
There is no byte stuffing when data are stored in skb.
TAILROOM is 2 byte crc + 1 byte eof.

st21nfca_hci_remove_len_crc was doing an incorrect operation on
the TAILROOM data.
If shdlc timer T2 is triggered, it will request to send the same data.
Before every hci data was lost after st21nfca_hci_remove_len_crc.

Byte stuffing was not correctly removed after a i2c read operation.
This was causing improper crc calculation when byte stuffing was

a3464ed2f1 ata: ahci_mvebu: new driver for Marvell Armada 380 AHCI interfaces
The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.

The ahci-platform.txt Device Tree binding documentation is gaining a

the addition of the Marvell Armada 380 AHCI support. It is therefore
time to reformat this list into a proper bullet list, and more
importantly order it alphabetically;
