[lttng-dev] [PATCH 1/3] statedump: adjust to v6.7 cpu topology struct

[Bruce Ashfield via lttng-dev <lttng-dev@lists.lttng.org>]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Adjusting the statedump to the following upstream commits:

  commit b9655e702dc5 [x86/cpu: Encapsulate topology information in cpuinfo_x86]
  commit e95256335d45 [x86/cpu: Move cpu_core_id into topology info]
  commit 02fb601d27a7 [x86/cpu: Move phys_proc_id into topology info]

We now have the topo struct, as well as some minor member name
changes.

Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>

Someone else may or may not already have this in flight,
but I didn't see anything on the list or in the git
repo.

I ran into this failure when working on the v6.7-rc
kernel as part of yocto project kernel updates.

Tweak as necessary, as I'm no expert in the right way
to version these sort of changes.
