Most code already uses consts for the struct kernel_param_ops,
sweep the kernel for the last offending stragglers. Other than
include/linux/moduleparam.h and kernel/params.c all other changes
were generated with the following Coccinelle SmPL patch. Merge
conflicts between trees can be handled with Coccinelle.
In the future git could get Coccinelle merge support to deal with
patch --> fail --> grammar --> Coccinelle --> new patch conflicts
automatically for us on patches where the grammar is available and
the patch is of high confidence. Consider this a feature request.

The num_pins field in the struct meson_domain_data must include also the
missing pins in the Meson8b SoC, otherwise the GPIO <-> pin mapping is
broken on this platform. Avoid also the dinamic allocation for GPIOs.

If a driver does not set interrupt triggering type when it calls
request_irq(), it means use the pin as the hardware/firmware has
configured it. There are some drivers doing this. One example is
drivers/input/serio/i8042.c that requests the interrupt like:
error = request_irq(I8042_KBD_IRQ, i8042_interrupt, IRQF_SHARED,
"i8042", i8042_platform_device);
It assumes the interrupt is already properly configured. This is true in
case of interrupts connected to the IO-APIC. However, some Intel
Braswell/Cherryview based machines use a GPIO here instead for the internal
keyboard controller.
This is a problem because even if the pin/interrupt is properly configured,
the irqchip ->irq_set_type() will never be called as the triggering flags
are 0. Because of that we do not have correct interrupt flow handler set
for the interrupt.
Fix this by adding a custom ->irq_startup() that checks if the interrupt
has no triggering type set and in that case read the type directly from the
hardware and install correct flow handler along with the mapping.

This patch fixes an inverted return value of the gpio get_direction
function.
The wrong value causes the direction sysfs entry and GPIO debugfs file
to indicate incorrect GPIO direction settings. In some cases it also
prevents setting GPIO output values.
The problem is also present in all other stable kernel versions since
linux-3.12.

mixer_regs_dump() was called in mixer_run(), which was called
under the register spinlock in mixer_graph_buffer() and
vp_video_buffer().
This would trigger a sysmmu pagefault with drm.debug=0xff because
of the large delay caused by the register dumping.
To keep consistency also move register dumping out of mixer_stop(),
which is the counterpart to mixer_run().

Disabling the CONFIG_DRM_EXYNOS_FIMD (e.g. by enabling of CONFIG_FB_S3C)
leads to build error:
drivers/built-in.o: In function `exynos_dp_dpms':
binder.c:(.text+0xd6a840): undefined reference to `fimd_dp_clock_enable'
binder.c:(.text+0xd6ab54): undefined reference to `fimd_dp_clock_enable'
Fix this by changing direct call to fimd_dp_clock_enable() into optional
call to exynos_drm_crtc_ops->clock_enable(). Only the DRM_EXYNOS_FIMD
implements this op.

Move the defines for the pixelformats that the mixer supports out
of mixer_graph_buffer() to the top of the source.
Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on
the plane's pf (and not bpp).
Also add handling of RGB565 and XRGB1555 to the switch statement and
exit early if the plane has an unsupported pf.
Partially based on 'drm/exynos: enable/disable blend based on pixel
format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>.
v2: Use the shorter MXR_FORMAT as prefix.
v3: Re-add ARGB8888 because of compatibility reasons
(suggested by Joonyoung Shim).

The video processor (VP) supports four formats: NV12, NV21 and its
tiled variants. All these formats are bi-planar, so the buffer
count in vp_video_buffer() is always 2.
Also properly exit if we're called with an invalid (non-VP) pixelformat.

Previously we were ignoring the buffer offsets that are
passed through the addfb2 ioctl. This didn't cause any
major issues, since for uni-planar formats (like XRGB8888)
userspace would most of the time just use offsets[0]=0.
However with NV12 offsets[1] is very likely non-zero.
So properly apply the offsets to our dma addresses.

The previous code had some special case handling for the buffer
count in exynos_drm_format_num_buffers().
This code was incorrect though, since this special case doesn't
exist for DRM. It stemmed from the existence of the special NV12M
V4L2 format. NV12 is a bi-planar format (separate planes for luma
and chroma) and V4L2 differentiates between a NV12 buffer where
luma and chroma is contiguous in memory (so no data between
luma/chroma), and a NV12 buffer where luma and chroma have two
explicit memory locations (which is then called NV12M).
This distinction doesn't exist for DRM. A bi-planar format always
explicitly comes with the information about its two planes (even
if these planes should be contiguous).

CPU1: stopping
But there isn't any particularly good reason to hold struct_mutex for
teardown, so just standardize on calling it without the mutex held and
use the _unlocked() versions for GEM obj unref'ing

During cmd rx, only new versions of H/W provide register to read back
the real number of byte returned by panel. For the old versions, reading
this register will not get the right number. In fact, we only need to
assume the returned data is the same size as we expected, because later
we will check the data type to detect error.

drm_mode_connector_attach_encoder() function call is missing
during eDP and DSI connector initialization. As a result,
no encoder is returned by DRM_IOCTL_MODE_GETCONNECTOR system
call. This change is to fix this issue.

When msm_framebuffer_init() fails before calling drm_framebuffer_init(),
drm_framebuffer_cleanup() [called in msm_framebuffer_destroy()]

The current iteration in get_dsi_id_from_intf() is wrong:
instead of iterating until hw_cfg->intf.count, we need to iterate
until MDP5_INTF_NUM_MAX here.
Let's take the example of msm8x16:
hw_cfg->intf.count = 1
intfs[0] = INTF_Disabled
intfs[1] = INTF_DSI
If we stop iterating once i reaches hw_cfg->intf.count (== 1),
we will miss the test for intfs[1].
Actually, this hw_cfg->intf.count entry is quite confusing and is not
(or *should not be*) used anywhere else; let's remove it.

The DRM_KMS_FB_HELPER config is selected only when DRM_MSM_FBDEV config is
selected. The driver accesses drm_fb_helper_* functions even when legacy fbdev
support is disabled in msm. Wrap around these functions with #ifdef checks to
prevent build break.

Avoid casts from pointers to fixed-size integers to prevent the compiler
from warning. Print virtual memory addresses using %p instead. Also turn
a couple of %d/%x specifiers into %zu/%zd/%zx to avoid further warnings
due to mismatched format strings.

Pull networking fixes from David Miller:
1) Don't leak ipvs->sysctl_tbl, from Tommi Rentala.
2) Fix neighbour table entry leak in rocker driver, from Ying Xue.
3) Do not emit bonding notifications for unregistered interfaces, from
Nicolas Dichtel.
4) Set ipv6 flow label properly when in TIME_WAIT state, from Florent
Fourcot.
5) Fix regression in ipv6 multicast filter test, from Henning Rogge.
6) do_replace() in various footables netfilter modules is missing a
check for 0 counters in the datastructure provided by the user. Fix
from Dave Jones, and found with trinity.
7) Fix RCU bug in packet scheduler classifier module unloads, from
Daniel Borkmann.
8) Avoid deadlock in tcp_get_info() by using u64_sync. From Eric
Dumzaet.
9) Input packet processing can race with inetdev_destroy() teardown,
fix potential OOPS in ip_error() by explicitly testing whether the
inetdev is still attached. From Eric W Biederman.
10) MLDv2 parser in bridge multicast code breaks too early while
parsing. Fix from Thadeu Lima de Souza Cascardo.
11) Asking for settings on non-zero PHYID doesn't work because we do not
import the command structure from the user and use the PHYID
provided there. Fix from Arun Parameswaran.
12) Fix UDP checksums with IPV6 RAW sockets, from Vlad Yasevich.
13) Missing NF_TABLES depends for TPROXY etc can cause build failures,
fix from Florian Westphal.
14) Fix netfilter conntrack to handle RFC5961 challenge ACKs properly,
