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.
Bluetooth HIDP selects INPUT and it really needs it to be there - module
depends on input core. And input core is never built on s390...
Marked as broken on s390, for now; if somebody has better ideas, feel

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.

Patch from Lennert Buytenhek
Introduce ixp2000_reg_wrb, which is a variant of ixp2000_reg_write
that does a readback from the target register, to make sure that
the write has been flushed out of the write buffer.
Unlike the previous (ineffective) readback in ixp2000_reg_write, this
readback is followed by an instruction that depends on the value of
the readback so that the CPU actually stalls until the readback has
completed.

Patch from Lennert Buytenhek
The workaround that we do for avoiding triggering ixp2400 erratum #66
involves mapping I/O pages using XCB=101 instead of XCB=000 so that we
prevent the I/O signal to the gasket from being asserted (which can
cause data corruption.) But XCB=101 mappings are write-buffered while
mappings using XCB=000 are not, which is why if we use XCB=101 mappings
we do a readback for every CSR store in an attempt to make sure that
the store has been pushed out of the xscale core and the gasket.
Unfortunately, there are two issues with this:
- we do a readback for every CSR store, which is wrong, because the
register we are writing to might have unwanted side-effects on read,
for example, in the case of the scratchpad ring enqueue/dequeue
registers; and
- the readback is totally ineffective in the way we currently do it,
because we just issue a load but do not issue any instruction that
depends on the return value of that load, so the xscale core does
not wait for the load to complete before continuing.
See this linux-arm-kernel mailing list post for further information:
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-September/031314.html
This means that my ixp2400 boxes have been running for many months
without a working readback in ixp2000_reg_write, without any apparent
adverse effects. Two of them have been running for a week now with
the actual readback deleted from ixp2000_reg_write, also without any
apparent ill effects.
So, because in its current form it does more harm than good, the
readback in ixp2000_reg_write should simply be killed, as the patch
below does.
