> v7->v8:
> Modify the logic used to select the MC domain (the change
> shouldn't modify the sched domains on any existing machines
> compared to v7, only how they are built)
> Reduce the severity of some parsing messages.
> Fix s390 link problem.
> Further checks to deal with broken PPTT tables.
> Various style tweaks, SPDX license addition, etc.
>
> v6->v7:
> Add additional patch to use the last cache level within the NUMA
> or socket as the MC domain. This assures the MC domain is
> equal or smaller than the DIE.
>
> Various formatting/etc review comments.
>
> Rebase to 4.16rc2
>
> v5->v6:
> Add additional patches which re-factor how the initial DT code sets
> up the cacheinfo structure so that its not as dependent on the
> of_node stored in that tree. Once that is done we rename it
> for use with the ACPI code.
>
> Additionally there were a fair number of minor name/location/etc
> tweaks scattered about made in response to review comments.
>
> v4->v5:
> Update the cache type from NOCACHE to UNIFIED when all the cache
> attributes we update are valid. This fixes a problem where caches
> which are entirely created by the PPTT don't show up in lstopo.
>
> Give the PPTT its own firmware_node in the cache structure instead of
> sharing it with the of_node.
>
> Move some pieces around between patches.
