Subject: page table walk in xen_{create, destroy}_contiguous_region
Date: Mon, 26 Jun 2006 15:53:16 +0200	[thread overview]
Message-ID: <44A002EC.76E4.0078.0@novell.com> (raw)

Is there a particular reason why these functions need to walk the page table rather than doing a much cheaper p2m
translation? vstart is assumed to be in the direct mapping area anyway (otherwise the uses of __pa() in the same
functions wouldn't be valid).

Thanks, Jan
