X-Git-Tag: v2.6.33-rc1~68^2~4 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5595b528b49a702c0428c0762bab60999648254c;p=pandora-kernel.git intel-iommu: Check for an RMRR which ends before it starts. Some HP BIOSes report an RMRR region (a region which needs a 1:1 mapping in the IOMMU for a given device) which has an end address lower than its start address. Detect that and warn, rather than triggering the BUG() in dma_pte_clear_range(). Cc: stable@kernel.org Signed-off-by: David Woodhouse --- Reading git-diff-tree failed
