The exynos fimd supports 5 window overlays. Only one window overlay of
fimd is used by the crtc, so we need plane feature to use the rest
window overlays.
This creates one ioctl exynos specific - DRM_EXYNOS_PLANE_SET_ZPOS, it
is the ioctl to decide for user to assign which window overlay.

This adds runtime PM feature for fimd. The runtime PM functions control

With DPMS ON and OFF requests, crtc dpms would be in charge of
just only device power such as fimd or hdmi and encoder dpms
in charge of device setting(mode setting and register updating)
and also lcd panel and digital TV power.

Call connector->funcs->dpms(DPMS_ON) rather than just setting
connector->dpms = DPMS_ON. This ensures that if the connector
has something to do to enable the output (rather than just using
drm_helper_connector_dpms helper directly), that this happens
at bootup. This solves an issue with connectors not getting
enabled from fbcon_init() when the driver is loaded.

If the bpc is set from the connector is 0, we then use it later to adjust
in a special case the HDMI pixel clock, however if the bpc is 0, we end up
passing a 0 pixel clock into the code.
I'm not sure if this is the correct answer or if we should avoid the HDMI
clock adjustment for 0 values.
This fixes a divide by 0 on my Llano system with a HDMI monitor and hdmi
audio enabled.

submission ioctl as well. Patch also convert current ib pool to use

Add a start fence driver helper function which will be call
once for each ring and will compute cpu/gpu addr for fence
depending on wether to use wb buffer or scratch reg.
This patch replace initialize fence driver separately which
was broken in regard of GPU lockup. The fence list for created,
emited, signaled must be initialize once and only from the
asic init callback not from the startup call back which is
call from the gpu reset.
v2: With this in place we no longer need to know the number of
rings in fence_driver_init, also writing to the scratch reg
before knowing its offset is a bad idea.
v3: rebase on top of change to previous patch in the serie

The GCT setup was used on Moorestown. The Oaktrail version uses a normal PC

This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1.
It blows up the i915 seqno tracking, resulting in the
BUG_ON(seqno == 0);
in i915_wait_request() triggering, which will cause lock-ups.

The "(insn & 0x01800000) != 0x01800000" test matches 'restore'
but that is a legitimate place to see the %lo() part of a 32-bit

rt6_alloc_cow().
After commit 8e2ec639173f325977818c45011ee176ef2b11f6 ("ipv6: don't
use inetpeer to store metrics for routes.") the test in rt6_alloc_cow()
for setting the ANYCAST flag is now wrong.
'rt' will always now have a plen of 128, because it is set explicitly
to 128 by ip6_rt_copy.
So to restore the semantics of the test, check the destination prefix
length of 'ort'.

gred_change_vq() is called under sch_tree_lock(sch).
This means a spinlock is held, and we are not allowed to sleep in this
context.
We might pre-allocate memory using GFP_KERNEL before taking spinlock,
but this is not suitable for stable material.

Same fix as 731abb9cb2 for ipip and sit tunnel.
Commit 1c5cae815d removed an explicit call to dev_alloc_name in
ipip_tunnel_locate and ipip6_tunnel_locate, because register_netdevice
will now create a valid name, however the tunnel keeps a copy of the
name in the private parms structure. Fix this by copying the name back
after register_netdevice has successfully returned.
This shows up if you do a simple tunnel add, followed by a tunnel show:
$ sudo ip tunnel add mode ipip remote 10.2.20.211
$ ip tunnel
tunl0: ip/ip remote any local any ttl inherit nopmtudisc
tunl%d: ip/ip remote 10.2.20.211 local any ttl inherit
$ sudo ip tunnel add mode sit remote 10.2.20.212
$ ip tunnel
sit0: ipv6/ip remote any local any ttl 64 nopmtudisc 6rd-prefix 2002::/16
sit%d: ioctl 89f8 failed: No such device
sit%d: ipv6/ip remote 10.2.20.212 local any ttl inherit

There is no obvious reason to add a default multicast route for loopback
devices, otherwise there would be a route entry whose dst.error set to
-ENETUNREACH that would blocking all multicast packets.
====================
[ more detailed explanation ]
The problem is that the resulting routing table depends on the sequence
of interface's initialization and in some situation, that would block all
muticast packets. Suppose there are two interfaces on my computer
(lo and eth0), if we initailize 'lo' before 'eth0', the resuting routing
table(for multicast) would be
# ip -6 route show | grep ff00::
unreachable ff00::/8 dev lo metric 256 error -101
ff00::/8 dev eth0 metric 256
When sending multicasting packets, routing subsystem will return the first
route entry which with a error set to -101(ENETUNREACH).
I know the kernel will set the default ipv6 address for 'lo' when it is up
and won't set the default multicast route for it, but there is no reason to
stop 'init' program from setting address for 'lo', and that is exactly what
systemd did.
I am sure there is something wrong with kernel or systemd, currently I preferred
kernel caused this problem.

This fixes a Data bus error on some SoCs. The first fix for this
problem did not solve it on all devices.
commit 6ae8ec27868bfdbb815287bee8146acbefaee867

ssb: fix init regression of hostmode PCI core
In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
accessed, but the sprom only exists when the ssb bus is connected over
a PCI bus to the rest of the system and not when the SSB Bus is the
main system bus. SoCs sometimes have a PCI host controller and there
this code will not be executed, but there are some old SoCs with an PCI
controller in client mode around and ssb_pcicore_fix_sprom_core_index()
should not be called on these devices too. The PCI controller on these
devices are unused, but without this fix it results in an Data bus
error when it gets initialized.

Emmanuel noticed that when mac80211 stops the queues
for aggregation that can leave a packet pending. This
packet will be given to the driver after the AMPDU
callback, but as a non-aggregated packet which messes
up the sequence number etc.
I also noticed by looking at the code that if packets
are being processed while we clear the WANT_START bit,
they might see it cleared already and queue up on
tid_tx->pending. If the driver then rejects the new
aggregation session we leak the packet.
Fix both of these issues by changing this code to not
stop the queues at all. Instead, let packets queue up
on the tid_tx->pending queue instead of letting them
get to the driver, and add code to recover properly
in case the driver rejects the session.
(The patch looks large because it has to move two
functions to before their new use.)
