[PATCH 0/3] x86_64, entry: some cleanup and simplification...

[Alexander van Heukelum]

Hi Andy,

Seems you are the person to talk now :). Good to see some activity in
the "entry" area of the kernel. I found some (very) old patches in this
area lying around and some time to dust them off.

Any chance you can review them?

They were redone on top of 22f2aa4a0361707a5cfb1de9d45260b39965dead
(x86/entry-devel in your tree) and this kernel is now running happily
on my laptop. I didn't try any benchmarking, though.

Greetings,
   Alexander
