This series depends on the:

[PATCH v3 0/5] x86/platform/uv: Add uv_sysfs platform driver

Series, next time when such a thing is the case, please add a note
about this to the cover letter.

Like with the "[PATCH v3 0/5] x86/platform/uv: Add uv_sysfs platform driver" series,
this series too should be merged in its entirety through the x86/tip tree (once the
other series is merged). Please also add this info to the cover letter.

I've one remark to patch 4 (which I send in a reply to that). So a v2 is going
to be necessary. Please include the above bits in the v2 cover-letter.

Regards,

Hans
