Subject: Re: [PATCH] x86, efi: 1:1 pagetable mapping for virtual EFI calls
Date: Thu, 06 Sep 2012 10:07:09 -0700	[thread overview]
Message-ID: <5048D83D.8000408@zytor.com> (raw)

Anyone care to refresh my memory why we can't use the "global" 
1:1+kernel map, possibly with some improvements (which would benefit the 
users of those maps too)?  With that I mean initial_page_map on i386 and 
trampoline_pgd on x86-64...
