Currently the Octeon Ethernet driver hardcodes the mapping between
interface/port and IPD port number. Since we have generic helpers for
the very same purpose, we might as well use them instead. This prevents
having the same information in multiple places.

CN68XX has a bit different WQE structure. This patch provides the new
definitions and converts the code to use the proper variant based on
the actual model.

The Pistachio SoC provides four general purpose timers, and allow
to implement a clocksource driver.
This driver can be used as a replacement for the MIPS GIC and MIPS R4K
clocksources and sched clocks, which are clocked from the CPU clock.
Given the general purpose timers are clocked from an independent clock,
this new clocksource driver will be useful to introduce CPUFreq support
for Pistachio machines.

For the clock to be used (e.g. get its rate through clk_get_rate)
it should be prepared and enabled first.
Also, while the clock is enabled the driver must hold a reference to it,
so let's remove the call to clk_put.

Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
machines, and each machine type provides its own gpio.h. However
only a handful really implement the GPIO API, most just forward
everythings to gpiolib.
The Alchemy machine is notable as it provides a system to allow
implementing the GPIO API at the board level. But it is not used by
any board currently supported, so it can also be removed.
For most machine types we can just remove the custom gpio.h, as well
as the custom wrappers if some exists. Some of the code found in
the wrappers must be moved to the respective GPIO driver.
A few more fixes are need in some drivers as they rely on linux/gpio.h
to provides some machine specific definitions, or used asm/gpio.h
instead of linux/gpio.h for the gpio API.

Weak header file declarations are error-prone because they make every
definition weak, and the linker chooses one based on link order (see
10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
decl")).
mips_cdmm_phys_base() is defined only in arch/mips/mti-malta/malta-memory.c
so there's no problem with multiple definitions. But it works better to
have a weak default implementation and allow a strong function to override
it. Then we don't have to test whether a definition is present, and if
there are ever multiple strong definitions, we get a link error instead of
calling a random definition.
Add a weak mips_cdmm_phys_base() definition and remove the weak annotation
from the declaration in arch/mips/include/asm/cdmm.h.

Pull device mapper update from Mike Snitzer:
- a couple small cleanups in dm-cache, dm-verity, persistent-data's
dm-btree, and DM core.
- a 4.1-stable fix for dm-cache that fixes the leaking of deferred bio
prison cells
- a 4.2-stable fix that adds feature reporting for the dm-stats
features added in 4.2
- improve DM-snapshot to not invalidate the on-disk snapshot if
snapshot device write overflow occurs; but a write overflow triggered
through the origin device will still invalidate the snapshot.
- optimize DM-thinp's async discard submission a bit now that late bio
splitting has been included in block core.
- switch DM-cache's SMQ policy lock from using a mutex to a spinlock;
improves performance on very low latency devices (eg. NVMe SSD).
- document DM RAID 4/5/6's discard support
[ I did not pull the slab changes, which weren't appropriate for this

The patch just to re-submit the patch "db3421c114cfa6326" because the
patch "4d494cdc92b3b9a0" remove the change.
Clear any pending receive interrupt before we process a pending packet.
This helps to avoid any spurious interrupts being raised after we have
fully cleaned the receive ring, while still allowing an interrupt to be
raised if we receive another packet.
The position of this is critical: we must do this prior to reading the
next packet status to avoid potentially dropping an interrupt when a
packet is still pending.

Pull core block updates from Jens Axboe:
"This first core part of the block IO changes contains:
- Cleanup of the bio IO error signaling from Christoph. We used to
rely on the uptodate bit and passing around of an error, now we
store the error in the bio itself.
- Improvement of the above from myself, by shrinking the bio size
down again to fit in two cachelines on x86-64.
- Revert of the max_hw_sectors cap removal from a revision again,
from Jeff Moyer. This caused performance regressions in various
tests. Reinstate the limit, bump it to a more reasonable size
instead.
- Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
Most devices have huge trim limits, which can cause nasty latencies
when deleting files. Enable the admin to configure the size down.
We will look into having a more sane default instead of UINT_MAX
sectors.
- Improvement of the SGP gaps logic from Keith Busch.
- Enable the block core to handle arbitrarily sized bios, which
enables a nice simplification of bio_add_page() (which is an IO hot
path). From Kent.
- Improvements to the partition io stats accounting, making it
faster. From Ming Lei.
- Also from Ming Lei, a basic fixup for overflow of the sysfs pending
file in blk-mq, as well as a fix for a blk-mq timeout race
condition.
- Ming Lin has been carrying Kents above mentioned patches forward
for a while, and testing them. Ming also did a few fixes around

Xen's PV network protocol includes messages to add/remove ethernet
multicast addresses to/from a filter list in the backend. This allows
the frontend to request the backend only forward multicast packets
which are of interest thus preventing unnecessary noise on the shared
ring.
The canonical netif header in git://xenbits.xen.org/xen.git specifies
the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal
necessary changes have been pulled into include/xen/interface/io/netif.h.
To prevent the frontend from extending the multicast filter list
arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries.
This limit is not specified by the protocol and so may change in future.
If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD
sent by the frontend will be failed with NETIF_RSP_ERROR.

Commit a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.")
added a new argument to fixed_phy_register(), but missed to update bgmac
driver, causing the following build failure:
drivers/net/ethernet/broadcom/bgmac.c:1450:2: error: too few arguments to function 'fixed_phy_register'
Add the missing argument.

Looking other drm drivers, there is no the restriction that framebuffer
has only one buffer in .create_handle() callback. They use just first
buffer.
If this limitation is removed, there is no reason keeping buffer count
for framebuffer, so we can remove buf_cnt from struct exynos_drm_fb.

It can get exynos_gem object via function argument, so no need to call
exynos_drm_fb_gem_obj() in exynos_drm_fbdev_update.
It also can get struct drm_framebuffer *fb via helper->fb, so can remove
a function argument for it.

The exynos_drm_fb_set_buf_cnt() is used to set buffer count only in
exynos_drm_fbdev_update(). This patch sets directly buffer count in
exynos_drm_framebuffer_init() without using exynos_drm_fb_set_buf_cnt(),
so there is no any reason to keep exynos_drm_fb_set_buf_cnt().
