3c929c6f5a libata: New driver for OCTEON SOC Compact Flash interface (v7).
Cavium OCTEON processor support was recently merged, so now we have
this CF driver for your consideration.

Most OCTEON variants have *no* DMA or interrupt support on the CF
interface so for these, only PIO is supported.  Although if DMA is
available, we do take advantage of it.

3ada9c1264 libata: Add another column to the ata_timing table.
The forthcoming OCTEON SOC Compact Flash driver needs an additional
timing value that was not available in the ata_timing table.  I add a
new column for dmack_hold time.  The values were obtained from the
Compact Flash specification Rev 4.1.

16028232bf pata_atiixp: update port enabledness test handling
Port enabledness test fits much better into init_one() instead of
pre_reset().  The reason why these tests are in pre_reset() is purely
historical at this point.  Move it to init_one().  This will help
further changes.

94be9a58d7 [libata] get-identity ioctl: Fix use of invalid memory pointer
for SAS drivers.

Caught by Ke Wei (and team?) at Marvell.

Also, move the ata_scsi_ioctl export to libata-scsi.c, as that seems to be the
general trend.

e720b9e498 IDE: fix sparse signed-ness errors with host->host_busy
The host_busy field in struct ide_host defaults to a
signed-long, where most arch's test_and_set_bit_*
macros use an unsigned long.

Change to using an unsigned long, which on ARM removes

Restart the request queue early for REQ_TYPE_PM_RESUME requests
(though there is only one resume request for the whole resume
sequence it stays in the queue until is fully completed and now
depends on kblockd for processing consequential resume states).

18e6959c38 mm: fix assertion
This assertion is incorrect for lockless pagecache.  By definition if we
have an unpinned page that we are trying to take a speculative reference
to, it may become the tail of a compound page at any time (if it is
freed, then reallocated as a compound page).

It was still a valid assertion for the vmscan.c LRU isolation case, but
it doesn't seem incredibly helpful...  if somebody wants it, they can
put it back directly where it applies in the vmscan code.
