The dev_kfree_skb in islpci_eth_transmit happens while irqs are still
disabled, so either dev_kfree_skb_irq needs to be used or the skb
needs to be freed after irqs have been enabled again. This patch
should fix it.

This one from my DMA_{32,64}BIT_MASK series did not seem to make it
through to upstream.
Use the DMA_{32,64}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
This patch includes dma-mapping.h explicitly because it caused errors
on some architectures otherwise.

We want ->tf_read() to get a complete snapshot of all taskfile
registers, without requiring the callers to manually call
ata_chk_status() and ata_chk_err() themselves.
This also fixes a minor bug in sata_vsc where the lower bits of the
feature register were incorrectly placed in the HOB (high order bits)
portion of struct ata_taskfile.
switched to simple_read_from_buffer(), killed broken use of min().
Incidentally, that use of min() had been fixed once, only to be
reintroduced in commit 4244f72436ab77c3c29a6447af81734ab3925d85:

- if (count > IMGSIZE - *ppos)
- count = IMGSIZE - *ppos;
+ count = min ((loff_t)count, IMGSIZE - (*ppos));
Note the lovely use of cast to shut the warning about misuse of min()
up...

as-iosched deals with aliased requests differently from other ioscheds.
It links together aliased requests using rq->queuelist instead of
spilling alises to dispatch queue like other ioscheds do. Requests
linked in this way cannot be merged.
Unfortunately, generic q->last_merge handling patch didn't take this
into account and q->last_merge could be set to an aliased request
resulting in Badness, corrupt list and eventually panic.
This explicitly marks aliased requests to be unmergeable.

Change the phys_mem_access_prot() function to take a pfn instead of an
address. This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.
Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn. Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.
