Subject: [PATCH v2 0/5] Add uv_sysfs platform driver

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.

Justin Ernst (5):
  x86/platform/uv: Remove existing /sys/firmware/sgi_uv/ interface
  x86/platform/uv: Add and export uv_bios_* functions
  x86/platform/uv: Add new uv_sysfs platform driver
  x86/platform/uv: Update ABI documentation of /sys/firmware/sgi_uv/
  x86/platform/uv: Update MAINTAINERS for uv_sysfs driver
