Subject: x86: trim mtrr don't close gap for resource allocation.
X-Git-Tag: v2.6.25-rc7~41
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5dca6a1bb014875a17289fdaae8c31e0a3641c99;p=pandora-kernel.git

x86: trim mtrr don't close gap for resource allocation.

fix the bug reported here:

	http://bugzilla.kernel.org/show_bug.cgi?id=10232

use update_memory_range() instead of add_memory_range() directly
to avoid closing the gap.

( the new code only affects and runs on systems where the MTRR
  workaround triggers. )
