libata depended on SCSI command to have the correct length when
tranlating it into an ATA command. This generally worked for commands
issued by SCSI HLD but user could issue arbitrary broken command using
sg interface.Also, when building ATAPI command, full command size was always
copied. Because some ATAPI devices needs bytes after CDB cleared, if
upper layer doesn't clear bytes after CDB, such devices will
malfunction. This necessiated recent clear-garbage-after-CDB fix in
sg interfaces. However, scsi_execute() isn't fixed yet and HL-DT-ST
DVD-RAM GSA-H30N malfunctions on initialization commands issued from
SCSI.This patch makes xlat functions always consider SCSI cmd_len. Each
translation function checks for proper cmd_len and ATAPI translaation
clears bytes after CDB.Signed-off-by: Tejun Heo

xlat function will be updated to consider qc->scsicmd->cmd_len and

Signed-off-by: Jeff Garzik -
Variable names in xlat functions are quite confusing now. 'scsicmd'
is used for CDB while qc->scsicmd points to struct scsi_cmnd while
'cmd' is used for struct scsi_cmnd.This patch cleans up variable names in xlat functions such that 'scmd'
is used for struct scsi_cmnd and 'cdb' for CDB. Also, 'scmd' local
variable is added if qc->scsicmd is used multiple times.Signed-off-by: Tejun Heo

Since commit 368c73d4f689dae0807d0a2aa74c61fd2b9b075f the kernel will try
to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if
pci_assign_unassigned_resources() is used to do full resource assignment of
the bus. This fails because in the PIIX4 these BAR registers have
implicitly assumed values and read back as zero; it used to work because
the kernel used to just write zero to that register the read back value did
match what was written.The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource
as non-movable. This will also be useful to keep other import system
resources from being moved around - for example system consoles on PCI
busses.[akpm@osdl.org: cleanup]

This patch is designed to fix:
- Disk eating corruptor on KT7 after resume from RAM
- VIA IRQ handling
- VIA fixups for bus lockups after resume from RAMThe core of this is to add a table of resume fixups run at resume time.
We need to do this for a variety of boards and features, but particularly
we need to do this to get various critical VIA fixups done on resume.The second part of the problem is to handle VIA IRQ number rules which
are a bit odd and need special handling for PIC interrupts. Various
patches broke various boxes and while this one may not be perfect
(hopefully it is) it ensures the workaround is applied to the right
devices only.From: Jean Delvare
Now that PCI quirks are replayed on software resume, we can safely
re-enable the Asus SMBus unhiding quirk even when software suspend support
is enabled.[akpm@osdl.org: fix const warning]

Use pci_find_ht_capability() in drivers/pci/htirq.c
Signed-off-by: Michael Ellerman
Signed-off-by: Greg Kroah-Hartman -
There are already several places in the kernel that want to search a PCI
device for a given Hypertransport capability. Although this is possible
using pci_find_capability() etc., it makes sense to encapsulate that
logic in a helper - pci_find_ht_capability().To cater for searching exhaustively for a capability, we also provide
pci_find_next_ht_capability().We also need to cater for the fact that the HT capability fields may be
either 3 or 5 bits wide. pci_find_ht_capability() deals with this for you,
but callers using the #defines directly must handle that themselves.Signed-off-by: Michael Ellerman
Signed-off-by: Greg Kroah-Hartman -
The current implementation of __pci_bus_find_cap() does two things,
first it determines the start of the capability chain for the device,
and then it trys to find the requested capability.Split these out, so that we can use the two parts independantly in
a subsequent patch. Externally visible behaviour should be unchanged.Signed-off-by: Michael Ellerman
Signed-off-by: Greg Kroah-Hartman -
This works like pci_dev_present but instead of returning boolean returns
the matching pci_device_id entry. This makes it much more useful. Code
bloat is basically nil as the old boolean function is rewritten in terms of
the new one.This will be used by the updated VIA PCI quirks for one
