Subject: [PATCH 0/5] [RFC] rework /dev/mem code vs. highmem and DEBUG_VIRTUAL
Date: Wed, 10 Apr 2013 16:32:49 -0700	[thread overview]
Message-ID: <20130410233249.7FFCB63B@viggo.jf.intel.com> (raw)

/dev/[k]mem are a bit of a mess.  They've probably been subtly
broken for a long time on highmem or when the kernel's page
tables have been munged in other ways.

This has only been lightly tested on x86.  Needs some review
and some wider testing before getting applied anywhere.
