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

Hi,

Quick self intro for the x86/tip maintainers: I have take over
drivers/platform/x86 maintainership from Andy.

So this touches files under both arch/x86/ and drivers/platform/x86/ ,
I believe this is best merged through the x86/tip tree and I don't
expect conflicts for the drivers/platform/x86/{Kconfig,Makefile} changes.

So here is my ack for merging this series through the x86/tip tree:
