[GIT PULL 0/9] intel_th: Updates for v5.3

[Alexander Shishkin]

Hi Greg,

There are the updates for the Intel TH driver that I have for the next
cycle. These are multi-window mode buffer management changes, mainly to
add support for software trace sinks.

One patch at the top is a dependency, from a pull request I sent last week
with fixes for v5.2 [1].

Individual patches are in follow-up emails, a signed tag is also pushed
out and available at the URL below. Please consider pulling or applying.
Thanks!
