libata used two separate sets of variables to record request size and
current offset for ATA and ATAPI. This is confusing and fragile.
This patch replaces qc->nsect/cursect with qc->nbytes/curbytes and
kills them. Also, ata_pio_sector() is updated to use bytes for
qc->cursg_ofs instead of sectors. The field used to be used in bytes
for ATAPI and in sectors for ATA.Signed-off-by: Tejun Heo

Handle pci_enable_device() failure while resuming. This patch kills
the "ignoring return value of 'pci_enable_device'" warning message and
propagates __must_check through ata_pci_device_do_resume().Signed-off-by: Tejun Heo

There were several places where ATA ID strings are manually terminated
and in some places possibly unterminated strings were passed to string
functions which don't limit length like strstr(). This patch converts
all of them over to ata_id_c_string().Signed-off-by: Tejun Heo

* Kill _OFS suffixes in ATA_ID_{SERNO|FW_REV|PROD}_OFS for consistency
with other ATA_ID_* constants.* Kill ATA_SERNO_LEN
* Add and use ATA_ID_SERNO_LEN, ATA_ID_FW_REV_LEN and ATA_ID_PROD_LEN.
This change also makes ata_device_blacklisted() use proper length
for fwrev.Signed-off-by: Tejun Heo

An ATA controller in native mode may have one or more channels disabled
and not assigned resources. In that case the existing code crashes trying
to access I/O ports 0-7.Add the neccessary check.

This patch adds ATAPI support to the sata_promise driver.
This has been tested on both first- and second-generation
chips (20378 and 20575), and with both SATAPI and PATAPI
devices. CD-writing works.SATAPI DMA works on second-generation chips, but on
first-generation chips SATAPI is limited to PIO due
to what appears to be HW limitations.
PATAPI DMA works on both first- and second-generation
chips, but requires the separate PATA support patch
before it can be used on TX2plus chips.The functional changes to the driver are:
- remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS
- add ->check_atapi_dma() operation to enable DMA for bulk data
transfers but force PIO for other ATAPI commands; this filter
is from Promise's driver and largely matches pata_pdc207x.c
- use a more restrictive ->check_atapi_dma() on first-generation
chips to force SATAPI to always use PIO
- add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(),
and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver
while non-DMA protocols are handed over to libata generic code
- add pdc_issue_atapi_pkt_cmd() to handle the initial steps in
issuing ATAPI DMA commands before sending the actual CDB;
this procedure was ported from Promise's driverSigned-off-by: Mikael Pettersson

This patch implements a simple way of setting up per-port
flags on the SATA+PATA Promise TX2plus chips, which is a
prerequisite for supporting the PATA port on those chips.It is based on the observation that ap->flags isn't really
used until after ->port_start() has been invoked. So it
places the "exceptional" per-port flags array in the driver's
private host structure, and uses it in ->port_start() to
finalise the port's flags.This patch obsoletes the #promise-sata-pata branch included
in the #all branch.Signed-off-by: Mikael Pettersson

Add a driver for the IT8213 which is a single channel ICH-ish PATA
controller. As it is very different to the IT8211/2 it gets its own
driver. There is a legacy drivers/ide driver also available and I'll post
that once I get time to test it all out (probably early January). If
anyone else needs the drivers/ide driver and wants to do the merge for
drivers/ide (Bart ??) then I'll forward it.[akpm@osdl.org: add PCI ID, constify needed_pio[]]

The SiS966/966L has different PCI-IDs for native mode and AHCI mode.
The SiS966 supports four SATA ports only in native mode.Added additional PCI-ID 0x0183 for SiS965/965L.
this patch is based on the code from David Wang from SiS Corporation published on SiS Website.

remap() the region we get from mmap() to mark the fact that we are
using all of the available slack space. Any slack space is used
to form a simple brk region, and potentially more stack space than
requested at load time.Any searches of the vma chain may well fail looking for
stack (and especially arg) addresses if the remaping is not done.
The simplest example is /proc//cmdline, since the args
are pretty much always at the top of the data/bss/stack region.Signed-off-by: Greg Ungerer

This adds the remaining changes which should have been part of the
review process.- the define command is inappropriate (it's primarily for rule
definitions)
- execute commands in the current dir as all other commands
- .*.tmp (but not .*.null) files are also removed up by "make clean"
- printf has other side effects, just use "echo -e"
- proper quoting
- proper indentationSigned-off-by: Roman Zippel
