X-Git-Tag: v2.6.33-rc1~374^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ccef086454d4c97e7b722e9303390207d681cb4c;p=pandora-kernel.git

x86, mm: Correct the implementation of is_untracked_pat_range()

The semantics the PAT code expect of is_untracked_pat_range() is "is
this range completely contained inside the untracked region."  This
means that checkin 8a27138924f64d2f30c1022f909f74480046bc3f was
technically wrong, because the implementation needlessly confusing.

The sane interface is for it to take a semiclosed range like just
about everything else (as evidenced by the sheer number of "- 1"'s
removed by that patch) so change the actual implementation to match.
