commit 77c5fd19075d299fe820bb59bb21b0b113676e20 upstream.
pata_mpc52xx supports BMDMA but inherits ata_sff_port_ops which
triggers BUG_ON() when a DMA command is issued. Fix it.

commit 687a993339c4f3a63654746230da3aab8bbdbffd upstream.
While separating out BMDMA irq handler from SFF, commit c3b28894
(libata-sff: separate out BMDMA irq handler) incorrectly made
__ata_sff_port_intr() consider an IRQ to be an idle one if the host
state was transitioned to HSM_ST_ERR by ata_bmdma_port_intr().
This makes BMDMA drivers ignore IRQs reporting host bus error which
leads to timeouts instead of triggering EH immediately. Fix it by
making __ata_sff_port_intr() consider the IRQ to be an idle one iff
the state is HSM_ST_IDLE. This is equivalent to adding HSM_ST_ERR to
the "break"ing case but less error-prone.

commit 2a5f07b5ec098edc69e05fdd2f35d3fbb1235723 upstream.
SCSI commands may be issued between __scsi_add_device() and dev->sdev
assignment, so it's unsafe for ata_qc_complete() to dereference
dev->sdev->locked without checking whether it's NULL or not. Fix it.

commit 6ad601955315b010a117306b994f2204fae85fdc upstream.
ATA devices don't send D2H Reg FIS after an successful ATA PIO data-in
command. The host is supposed to take the TF and E_Status of the
preceding PIO Setup FIS. Update ahci_qc_fill_rtf() such that it takes
TF + E_Status from PIO Setup FIS after a successful ATA PIO data-in
command.
Without this patch, result_tf for such a command is filled with the
content of the previous D2H Reg FIS which belongs to a previous
command, which can make the command incorrectly seen as failed.
* Patch updated to grab the whole TF + E_Status from PIO Setup FIS
instead of just E_Status as suggested by Robert Hancock.

libata depends on scsi_host_template for module reference counting and
sht's should be owned by each low level driver. During libahci split,
the sht was left with libahci.ko leaving the actual low level drivers
not reference counted. This made ahci and ahci_platform always
unloadable even while they're being actively used.
Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for
each low level ahci driver.
stable: only applicable to 2.6.35.

ahci_do_softreset() compared the current time and deadline in reverse
when calculating timeout for SRST issue. The result is that if
@deadline is in future, SRST is issued with 0 timeout, which hasn't
caused any problem because it later waits for DRDY with the correct
timeout. If deadline is already exceeded by the time SRST is about to
be issued, the timeout calculation underflows and if the device
doesn't respond, timeout doesn't trigger for a _very_ long time.
Reverse the incorrect comparison order.

Remove harmful BUG_ON() from ata_bmdma_qc_issue(),
as it casts too wide of a net and breaks sata_mv.
It also crashes the kernel while doing the BUG_ON().

the case of POLLING for a BMDMA operation.

Fix DSM/TRIM commands in sata_mv (v2).
These need to be issued using old-school "BM DMA",
rather than via the EDMA host queue.
Since the chips don't have proper BM DMA status,
we need to be more careful with setting the ATA_DMA_INTR bit,
since DSM/TRIM often has a long delay between "DMA complete"
and "command complete".
GEN_I chips don't have BM DMA, so no TRIM for them.

'make htmldocs' has a fatal error when processing libata.xml, as seen
below. The string "Example patterns:" (or any string with "example.*:"
in it AFAIK) causes some part of the doc generation tool chain to try to
produce an <informalexample> block without a beginning <para>, but
there is an ending </para> generated, which throws things out of kilter.
I don't even know where (what program) this is happening in.
I searched in docproc and xmlto and in some XML stylesheets without
finding anything. If anyone can give me pointers about this, please do.
Until this is fixed, let's just spell "Example" as "Sample"
and match up the double quotation marks while there.

Remove the current bio flags and reuse the request flags for the bio, too.
This allows to more easily trace the type of I/O from the filesystem
down to the block driver. There were two flags in the bio that were
missing in the requests: BIO_RW_UNPLUG and BIO_RW_AHEAD. Also I've
renamed two request flags that had a superflous RW in them.
Note that the flags are in bio.h despite having the REQ_ name - as
blkdev.h includes bio.h that is the only way to go for now.

SIDPR window registers are shared across ports and as each access is
done in two steps, accesses to different ports under EH may race.
This primarily is caused by incorrect host locking in EH context and
should be fixed by defining locking requirements for each EH operation
which can be used during EH and enforcing them but for now work around
the problem by adding a dedicated SIDPR lock and grabbing it for each
SIDPR access.

The driver is using platform_driver_probe() during initialization,
so ahci_driver.probe hook is never used.
But it causes the following (harmless, luckily) section mismatch:
WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference
from the variable ahci_driver to the function .init.text:ahci_probe()
This patch removes the ahci_driver.probe assignment, thus fixes
the warning.
p.s. Note that there's another patch[1] from Rene Bolldorf that
tried to solve the same issue by __refdata annotation. __refdata
says that this reference is actually OK, but in fact it is not OK,
because dereferencing .probe() will cause problems. So the proper
fix is to remove the assignment.
