[PATCH 0/2] Only parse exactmap once, introduce memmap=resetusablemap

[trenn@xxxxxxx (Thomas Renninger)]

this is a clean resend of Yinghai's memmap= extensions.
They were discussed on lkml in a thread with subject:
[PATCH] x86 e820: only void usable memory areas in memmap=exactmap case

The patches are based on origin/x86/mm2 where another memmap= 
enhancement from Yinghai is already queued.

Would be great if these can be queued there as well.

Thanks,

   Thomas
