sata_sil used to trigger HSM error if IRQ occurs during polling

However, as of 2.6.20, all IDENTIFYs are performed by polling and
device detection sometimes fails due to spurious IRQ. This patch

I don't have enough info to blame this specific -rc* kernel,

So, a datapoint, but not much of clue beyond that.

Many block drivers (aoe, iscsi) really want refcountable pages in

Currently xlog_alloc allocates memory for the iclogs first, then
allocates a buffer using xfs_buf_get_empty and finally assigns
the memory to the buffer. We don't really want to do this, but
rather allocate a buffer with memory attached to it using
xfs_buf_get_noaddr. There's a subtile change
Currently xfs_buf_get_noaddr allocates memory using kmem_alloc which
can end up either in kmalloc or vmalloc and assigns it to the buffer.
This patch changes it to allocate individual pages and if there is
more then one maps it into kernel virtual space using vmap.
