Atomic modesetting: now with modesetting support.
v2: Moved drm_atomic_set_mode_prop_for_crtc from previous patch; removed
state->active fiddling, documented return code. Changed property
type to DRM_MODE_PROP_BLOB.

Add a blob property tracking the current mode to the CRTC state, and
ensure it is properly updated and referenced.
v2: Continue using crtc_state->mode inside getcrtc, instead of reading
out the mode blob. Use IS_ERR and PTR_ERR from create_blob. Move
set_mode_prop_for_crtc to later patch where it actually gets used.
Enforce !!state->enable == !!state->mode_blob inside
drm_atomic_crtc_check.

Add a new helper, to be used later for blob property management, that
sets the mode for a CRTC state, as well as updating the CRTC enable/active
state at the same time.
v2: Do not touch active/mode_changed in CRTC state. Document return
value. Remove stray drm_atomic_set_mode_prop_for_crtc declaration.
v3: Remove i915 changes, and leave it directly bashing crtc_state->mode
for the meantime.

Unfortunately old userspace didn't clear this properly, but since
we've added fb modifiers that's fixed. Checking properly that unused
fields is important for abi extensions, and just right now there's a
bunch of discussions going on about how exactly the additional aux
planes for render compression should be specified.
So let's first make sure that the values in those additional fields
can be indeed used.

Allow drm_bridge objects to link to each other in order to form an encoder
chain. The requirement for creating a chain of bridges comes because the
MSM drm driver uses up its encoder and bridge objects for blocks within
the SoC itself. There isn't anything left to use if the SoC display output
is connected to an external encoder IC. Having an additional bridge
connected to the existing bridge helps here. In general, it is possible for
platforms to have multiple devices between the encoder and the
connector/panel that require some sort of configuration.
We create drm bridge helper functions corresponding to each op in
'drm_bridge_funcs'. These helpers call the corresponding
'drm_bridge_funcs' op for the entire chain of bridges. These helpers are
used internally by drm_atomic_helper.c and drm_crtc_helper.c.
The drm_bridge_enable/pre_enable helpers execute enable/pre_enable ops of
the bridge closet to the encoder, and proceed until the last bridge in the
chain is enabled. The same holds for drm_bridge_mode_set/mode_fixup
helpers. The drm_bridge_disable/post_disable helpers disable the last
bridge in the chain first, and proceed until the first bridge in the chain
is disabled.
drm_bridge_attach() remains the same. As before, the driver calling this
function should make sure it has set the links correctly. The order in
which the bridges are connected to each other determines the order in which
the calls are made. One requirement is that every bridge in the chain
should point the parent encoder object. This is required since bridge
drivers expect a valid encoder pointer in drm_bridge. For example, consider
a chain where an encoder's output is connected to bridge1, and bridge1's
output is connected to bridge2:
/* Like before, attach bridge to an encoder */
bridge1->encoder = encoder;
ret = drm_bridge_attach(dev, bridge1);
..
/*
* set the first bridge's 'next' bridge to bridge2, set its encoder
* as bridge1's encoder
*/
bridge1->next = bridge2
bridge2->encoder = bridge1->encoder;
ret = drm_bridge_attach(dev, bridge2);
...
...
This method of bridge chaining isn't intrusive and existing drivers that
use drm_bridge will behave the same way as before. The bridge helpers also
cleans up the atomic and crtc helper files a bit.

drm_atomic_helper_commit_planes calls all atomic_begin's first,
then updates all planes, finally calling atomic_flush.
Some drivers may want to things like disabling irq's
from their atomic_begin, in which case a second call to atomic_begin
will splat. By using commit_planes_on_crtc on each crtc in the

- Add the interrupts & events modules, including new IOCTLs to create and wait
on events. The HSA RT open source stack is mainly using events to know when
a dispatched work has been completed. In addition, this module is
a pre-requisite for the next module I'm going to upstream - debugger support
This module also handles H/W exceptions, such as memory exception received
through the IOMMUv2 H/W and Bad Opcode exception receieved from the GPU.
- Adding a new kernel module parameter to let the user decide whether he wants
to receive a SIGTERM when a memory exception occurs inside the GPU kernel and
the HSA application doesn't wait on an appropriate event, or if he just want
to receive notification about this event in dmesg. The default is the latter.
- Additional improvements for SDMA code
- Update my email address in Maintainers file.

This patch adds a new kernel module parameter to amdkfd,
called send_sigterm.
This parameter specifies whether amdkfd should send the
SIGTERM signal to an HSA process, when the following conditions
occur:
1. The GPU triggers an exception regarding a kernel that was
issued by this process.
2. The HSA process isn't waiting on an event that handles
this exception.
The default behavior is not to send a SIGTERM and suffice
with a dmesg error print.

This patch adds the events module (kfd_events.c) and the interrupt
handle module for Kaveri (cik_event_interrupt.c).
The patch updates the interrupt_is_wanted(), so that it now calls the
interrupt isr function specific for the device that received the
interrupt. That function(implemented in cik_event_interrupt.c)
returns whether this interrupt is of interest to us or not.
The patch also updates the interrupt_wq(), so that it now calls the
device's specific wq function, which checks the interrupt source
and tries to signal relevant events.

Increase limit of signal events to 4096 per process
Remove bitfields from struct cik_ih_ring_entry
Rename radeon_kfd_event_mmap to kfd_event_mmap
Add debug prints to allocate_free_slot and allocate_signal_page

Remove error print from IOCTL path
Reformatted debug prints in kfd_event_mmap

This patch adds the interrupt handling module, kfd_interrupt.c, and its
related members in different data structures to the amdkfd driver.
The amdkfd interrupt module maintains an internal interrupt ring
per amdkfd device. The internal interrupt ring contains interrupts
that needs further handling. The extra handling is deferred to
a later time through a workqueue.
There's no acknowledgment for the interrupts we use. The hardware
simply queues a new interrupt each time without waiting.
The fixed-size internal queue means that it's possible for us to lose
interrupts because we have no back-pressure to the hardware.
However, only interrupts that are "wanted" by amdkfd, are copied into
the amdkfd s/w interrupt ring, in order to minimize the chances
for overflow of the ring.

Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.
Commit 195daf665a62 ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d293233 ("watchdog: Add watchdog enable/disable all functions").
There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.
This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.

- Allow free function to be overridden too, in case extra memory is

Pull btrfs fixes from Chris Mason:
"The first commit is a fix from Filipe for a very old extent buffer
