[PATCH v2 0/5] Add uv_sysfs platform driver

From: Justin Ernst
Date: Wed Nov 18 2020 - 11:48:57 EST


Introduce a new platform driver to gather topology information from UV systems
and expose that information via a sysfs interface at /sys/firmware/sgi_uv/.

This is version 2 with these changes since version 1:

* Re-introduced /sys/firmware/sgi_uv/coherence_id file in the new driver after
removing it in Patch 1/5. This keeps the userspace API unbroken.
