sunhme: fix dma warning in Sun HME
Fix dma-api-checking warnings in Sun HME
Sun HME driver is mapping the first fragment with dma_map_single and subsequent
fragments with dma_map_page. It is unmapping all fragments with dma_unmap_single
and that produces the warning.
This patch changes it so that it unmaps only the first fragment with
dma_unmap_single and subsequent fragments are unmapped with dma_unmap_page.

In testing we have found that skb_dma_map/unmap is incompatible with HW
IOMMU due to the fact that multiple mappings will return different results.
In order to correct this we need to remove skb_dma_map/unmap calls from the
e1000e driver.

ip: update the description of rp_filter in ip-sysctl.txt
The commit
27fed4175acf81ddd91d9a4ee2fd298981f60295 (ip: fix logic of
reverse path filter sysctl) has changed the logic of rp_filter. The
document about rp_filter is out of date. Now, setting
conf/all/rp_filte with 0 can also enable source validation.
Update the document according to the commit.

bnx2: EEH is failing with timeout
bnx2 is failing when a PCI error is detected. The error is the
following:

This error was caused because the way pci_restore_state() is working
