As Google/Intel will fix the BIOS/Coreboot issues with hardcoding
virtual interrupt numbers for keyboard/touchpad/touchscreen controllers
in ACPI tables, they will also update BOARD version number from 1.0
to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ
numbers on Strago boards to those that still carry older BIOSes.
Note that ideally not BOARD but BIOS version should have been updated.
However the BIOS version used by Chrome devices has format of
Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as
we do not have "less than" match mode for DMI data.

====================
bpf has been used extensively for tracing. For example, bcc
contains an almost full set of bpf-based tools to trace kernel
and user functions/events. Most tracing tools are currently
either filtered based on pid or system-wide.
Containers have been used quite extensively in industry and
cgroup is often used together to provide resource isolation
and protection. Several processes may run inside the same
container. It is often desirable to get container-level tracing
results as well, e.g. syscall count, function count, I/O
activity, etc.
This patch implements a new helper, bpf_get_current_cgroup_id(),
which will return cgroup id based on the cgroup within which
the current task is running.
Patch #1 implements the new helper in the kernel.
Patch #2 syncs the uapi bpf.h header and helper between tools
and kernel.
Patch #3 shows how to get the same cgroup id in user space,
so a filter or policy could be configgured in the bpf program
based on current task cgroup.
Changelog:

With the addition of "private_objs" in drm_atomic_state, we no longer
need to subclass drm_atomic_state to store state of share resources
that don't perfectly fit within planes/crtc/connector state information.
We can now save this state within drm_atomic_state itself using
the private objects.
Remove the infrastructure that allowed subclassing of drm_atomic_state
in the driver.

This replaces the usage of the subclassed atomic state (mdp5_state)
with a private_obj state embedded within drm_atomic_state. The latter
method is the preferred approach, since it's simpler to implement
and less prone to errors.
The new API replaces the older and equivalent mdp5_state usage in the
following pattern:
- References to "mdp5_kms->state" (i.e, the old/existing state) is
replaced with mdp5_get_existing_global_state(). In the atomic_check
path, this should be called with the glob_state_lock drm_modeset_lock
alredy taken.
- References to "mdp5_get_state()" are replaced with
mdp5_get_global_state(). This acquires glob_state_lock and uses
drm_atomic_get_private_obj_state() to create a new duplicated state.
Changes in v3:
- Acquire glob_state_lock in mdp5_smp.c
- Added to the msm atomic helper patch set

Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are
implemented as a part of atomic state by subclassing drm_atomic_state.
The preferred approach is to use the drm_private_obj infrastructure
available in the atomic core.
mdp5_global_state is introduced as a drm atomic private object. The two
funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are
the two variants that will be used to access mdp5_global_state.
This will replace the existing mdp5_state struct (which subclasses
drm_atomic_state) and the funcs around it. These will be removed later
once we mdp5_global_state is put to use everywhere.

- Added glob_state_lock instead of pushing it into the core

Currently the error pointer returned by msm_alloc_stolen_fb gets passed

Commit 62e3a3e342 changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.
However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)

though the ECC unit is larger. Unless / until the ACPI specification
provides a non-ambiguous way to communicate this property do not expose
this to userspace.
Software that had been using this property must already be prepared for
