Christoph added a generic include/linux/pci-dma-compat.h, so now there's
one place with most of the PCI DMA interfaces. Move more PCI DMA-related
things there:
- The PCI_DMA_* direction constants from linux/pci.h
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
CONFIG_PCI implementations from drivers/pci/pci.c
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
!CONFIG_PCI stubs from linux/pci.h
- The pci_set_dma_mask() and pci_set_consistent_dma_mask()
!CONFIG_PCI stubs from linux/pci.h

For a long time all architectures implement the pci_dma_* functions using
the generic DMA API, and they all use the same header to do so.
Move this header, pci-dma-compat.h, to include/linux and include it from
the generic pci.h instead of having each arch duplicate this include.

This follows the way of handling other flashes and cleans code a bit. As

2) This code isn't MIPS specific

Jiri Bohac is reporting for a problem where the attempt
to reschedule existing connection to another real server
needs proper redirect for the conntrack used by the IPVS
connection. For example, when IPVS connection is created
to NAT-ed real server we alter the reply direction of
conntrack. If we later decide to select different real
server we can not alter again the conntrack. And if we
expire the old connection, the new connection is left
without conntrack.
So, the only way to redirect both the IPVS connection and
the Netfilter's conntrack is to drop the SYN packet that
hits existing connection, to wait for the next jiffie
to expire the old connection and its conntrack and to rely
on client's retransmission to create new connection as
usually.
Jiri Bohac provided a fix that drops all SYNs on rescheduling,
I extended his patch to do such drops only for connections
that use conntrack. Here is the original report from Jiri Bohac:
Since commit dc7b3eb900aa ("ipvs: Fix reuse connection if real server
is dead"), new connections to dead servers are redistributed
immediately to new servers. The old connection is expired using
ip_vs_conn_expire_now() which sets the connection timer to expire
immediately.
However, before the timer callback, ip_vs_conn_expire(), is run
to clean the connection's conntrack entry, the new redistributed
connection may already be established and its conntrack removed
instead.
Fix this by dropping the first packet of the new connection
instead, like we do when the destination server is not available.
The timer will have deleted the old conntrack entry long before
the first packet of the new connection is retransmitted.
Fixes: dc7b3eb900aa ("ipvs: Fix reuse connection if real server is dead")

Although most of USB devices are hot-plug's, there are still some devices
are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
If these kinds of USB devices are multiple functions, and they can supply
other interfaces like i2c, gpios for other devices, we may need to
describe these at device tree.
In this commit, it uses "reg" in dts as physical port number to match
the phyiscal port number decided by USB core, if they are the same,
then the device node is for the device we are creating for USB core.

Stephen Rothwell reported this linux-next build failure:
http://lkml.kernel.org/r/20160226164406.065a1ffc@canb.auug.org.au
... caused by the Memory Protection Keys patches from the tip tree triggering
a newly introduced build-time sanity check on an ARM build, because they changed
the ABI of siginfo in an unexpected way.
If u64 has a natural alignment of 8 bytes (which is the case on most mainstream
platforms, with the notable exception of x86-32), then the leadup to the
_sifields union matters:
typedef struct siginfo {
int si_signo;
int si_errno;
int si_code;
union {
...
} _sifields;
} __ARCH_SI_ATTRIBUTES siginfo_t;
Note how the first 3 fields give us 12 bytes, so _sifields is not 8
naturally bytes aligned.
Before the _pkey field addition the largest element of _sifields (on
32-bit platforms) was 32 bits. With the u64 added, the minimum alignment
requirement increased to 8 bytes on those (rare) 32-bit platforms. Thus
GCC padded the space after si_code with 4 extra bytes, and shifted all
_sifields offsets by 4 bytes - breaking the ABI of all of those
remaining fields.
On 64-bit platforms this problem was hidden due to _sifields already
having numerous fields with natural 8 bytes alignment (pointers).
To fix this, we replace the u64 with an '__u32'. The __u32 does not
increase the minimum alignment requirement of the union, and it is
also large enough to store the 16-bit pkey we have today on x86.

Add device managed APIs for regmap_add_irq_chip() and
regmap_del_irq_chip() so that it can be managed by
device framework for freeing it.
This helps on following:
1. Maintaining the sequence of resource allocation and deallocation
regmap_add_irq_chip(&d);
devm_requested_threaded_irq(virq)
On free path:
regmap_del_irq_chip(d);
and then removing the irq registration.
On this case, regmap irq is deleted before the irq is free.
This force to use normal irq registration.
By using devm apis, the sequence can be maintain properly:
devm_regmap_add_irq_chip(&d);
devm_requested_threaded_irq(virq);
and resource deallocation will be done in reverse order
by device framework.
2. No need to delete the regmap_irq_chip in error path or remove
callback and hence there is less code on this path.

Pull tracing fix from Steven Rostedt:
"A feature was added in 4.3 that allowed users to filter trace points
on a tasks "comm" field. But this prevented filtering on a comm field
that is within a trace event (like sched_migrate_task).
When trying to filter on when a program migrated, this change
prevented the filtering of the sched_migrate_task.
To fix this, the event fields are examined first, and then the extra
fields like "comm" and "cpu" are examined. Also, instead of testing
to assign the comm filter function based on the field's name, the
generic comm field is given a new filter type (FILTER_COMM). When
this field is used to filter the type is checked. The same is done
for the cpu filter field.
Two new special filter types are added: "COMM" and "CPU". This allows
users to still filter the tasks comm for events that have "comm" as
one of their fields, in cases that users would like to filter
sched_migrate_task on the comm of the task that called the event, and
not the comm of the task that is being migrated"

RxRPC: Rewrite part 1
Here's the first set of patches from my RxRPC rewrite, aimed at net-next.
These do some clean ups and bug fixes. Most of the changes are small, but
there are a couple of bigger changes:
(*) Convert call flag numbers and event numbers into enums. Then rename
the event numbers to all have _EV_ in their name to stop confusion.
Fix one instance of an event bit being used instead of a flag bit.
(*) A copy of the Rx protocol header is kept in the sk_buff private data.
Keep this in host byte order rather than network byte order as it
makes more sense. A number of other fields then get converted into
host byte order too.
Conversion between host and network byte order is then done at the
packet reception/generation stage.
This is based on net-next/master

DIV_ROUND_UP is defined in linux/kernel.h only for the kernel.
When ethtool.h is included by a userland app, we got the following error:
include/linux/ethtool.h:1218:8: error: variably modified 'queue_mask' at file scope
__u32 queue_mask[DIV_ROUND_UP(MAX_NUM_QUEUE, 32)];
^
Let's add a common definition in uapi and use it everywhere.
Fixes: ac2c7ad0e5d6 ("net/ethtool: introduce a new ioctl for per queue setting")

Now that applications need to explicitly ask for polling we can enable it
by default in blk-mq drivers. Note that this will only have an affect
on driver that supply a poll function, which currently only includes nvme.

This adds a flag that tells the file system that this is a high priority
request for which it's worth to poll the hardware. The flag is purely
advisory and can be ignored if not supported.

This way we can set kiocb flags also from the sync read/write path for
the read_iter/write_iter operations. For now there is no way to pass
flags to plain read/write operations as there is no real need for that,
and all flags passed are explicitly rejected for these files.
