Hi,
This is a first proposal to discuss the addition of in-fences support
to DRM. It adds a new struct to fence.c to abstract the use of sync_file
in DRM drivers. The new struct fence_collection contains a array with all
fences that a atomic commit needs to wait on
/**

FENCE_FD can now be set by the user during an atomic IOCTL, it
will be used by atomic_commit to wait until the sync_file is signalled,
i.e., the framebuffer is ready for scanout.

The struct aggregates fences that we need to wait on before proceed with
some specific operation. In DRM, for example, we may wait for a group of
fences to signal before we scanout the buffers related to those fences.

Assigning a device group to a regulator does not change its state. To
change the state of a regulator a message over the powerbus is required.
Also, the check for the current state of a regulator should not count on
a device group being assigned, but on the current resource state.

This results in calling pat_init() on BSP only since APs do not call

In preparation for fixing a regression caused by 'commit 9cd25aac1f44
("x86/mm/pat: Emulate PAT when it is disabled")', PAT needs to
provide an interface that prevents the OS from initializing the
PAT MSR.
PAT MSR initialization must be done on all CPUs using the specific
sequence of operations de
Xen supports PAT without MTRRs for its guests. In order to
enable WC attribute, it was necessary for xen_start_kernel()
to call pat_init_cache_modes() to update PAT table before
starting guest kernel.
Now that the kernel initializes PAT table to the BIOS handoff
state when MTRR is disabled, this

There is code in tools/ that is directly including this file from the
kernel, and this is verboten for a while, copy it so that the next csets
can fix this situation.

To avoid parsing event->header.misc in many locations.
This will also allow setting perf.sample.{ip,cpumode} in a single place,
from tracepoint fields, as needed by 'perf kvm' with PPC guests, where
the guest hardware counters is not available at the host.

Since none of the perf_event fields are used anymore, just the
perf_sample ones, and since this resolves to (map, symbol) from data
structures within struct thread, rename it to thread__resolve and make
the argument ordering similar to the one in machine__resolve().
