Duplicate the current UV procfs leaves to the uv_sysfs driver so they show
up under /sys/firmware/sgi_uv. Show a 'deprecated' warning message if
any of the old /proc/sgi_uv leaves are used.
These patches depend on the prior v3 patchset sent by Justin Ernst <[email protected]>
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
v2: Updated to apply to v3 of dependency patch set listed above.

x86/platform/uv: Add kernel interfaces for obtaining system info.

AS with the previous series this series touches files under both
x86/platform and drivers/platform/x86. Like last time this is best merged
in its entirety through the x86/tip tree (which also has the previous set).
Here is my ack for the drivers/platform/x86 bits being merged through the
x86/tip tree:
