Ninja32 needs to set some flags to indicate it does 32bit IO. However it currently assigns this which
loses the initializing flag and causes a warning spew. Fix it to use a logical or as is intended.

libata: LITE-ON CX1-JB256-HP needs lower max_sectors
`changeable` is the "version" of mode page requested by the user.
It will be less confusing/misleading if we do not check it
"together" with the setting bits of the drive.
Not to mention that we currently have ata_mselect_*() implemented
in a way that each of them will serve exclusively a particular bit
on each page. The old style will hence make the condition look even
more unnecessarily arcane if the ata_msense_*() is reflecting more
than one bit.

Due to PCI subsystem behaviour, unloading AHCI driver will disable
MSI and enable INTx. When HBA supports MSIx or Multiple MSI, Driver's
irq handler doesn't clear GHC.IS register. It works well when reading or
writing data and GHC.IS is always non-zero. But when unloading driver
(or any other operation which causes disable MSIx and enable INTx), PCI
subsystem uses config write(Rx04.bit10) to enable INTx. Because
GHC.IS is non-zero, HBA will falsely assume some port needs interrupt
service. Then it asserts INTx. To make things worse, when AHCI controller
shares the same interrupt pin with other PCI device, that PCI device's ISR
will be called and nobody de-asserts previous INTx.
This patch clears GHC.IS in ahci_port_stop() even when using MSIx or
MMSI to prevent this case. It ensures GHC.IS is zero before PCI subsystem
enables INTx.

The taskfile protocol is a numeric value, and can not be ORed. Currently
this is harmless as the protocol is always zeroed before, but if it ever

Currently libata statically allows only 1-block (512-byte) payload
for each TRIM command. Each payload can carry 64 TRIM ranges since
each range requires 8 bytes.
It is silly to keep doing the calculation (512 / 8) in different
places. Hence, define the new ATA_MAX_TRIM_RNUM for the result.

Currently if a WRITE SAME (16) command is issued to the SATL with
"number of blocks" that is larger than the "Maximum write same length"
(which is the maximum number of blocks per TRIM command allowed in
libata, currently 65535 * 512 / 8 blocks), the SATL will accept the
command and translate it to a TRIM command with the upper limit.
However, according to SBC (as of sbc4r11.pdf), the "device server"
should terminate the command with "Invalid field in CDB" in that case.

Also, it should always be set to 1 if ATA_DFLAG_D_SENSE is set (when

The comment suggests we should be having an SPC-3 version descriptor
but the 0260h is the code for "SPC-2 (no version claimed)". Correct
it to 0300h so that it has the "SPC-3 (no version claimed)" descriptor.
Note that we are claiming SPC-3 version compatibility in the VERSION
field of the standard INQUIRY data. Therefore, I assume the typo was
on the code but not on the comment.
