4bb64fb981 SiS warning fixes
Somehow the sis_info133 external definition ended up in libata.h and that
was included by both drivers.  However libata.h contains libata-* specific
internals and clashing defines like DRV_NAME so this makes a mess.  Move
the extern into the C file and remove the warnings

246ce3b675 libata: add another IRQ calls (libata drivers)
This patch is against each libata driver.

Two IRQ calls are added in ata_port_operations.
- irq_on() is used to enable interrupts.
- irq_ack() is used to acknowledge a device interrupt.

In most drivers, ata_irq_on() and ata_irq_ack() are used for
irq_on and irq_ack respectively.

In some drivers (ex: ahci, sata_sil24) which cannot use them
as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

0d5ff56677 libata: convert to iomap
Convert libata core layer and LLDs to use iomap.

* managed iomap is used.  Pointer to pcim_iomap_table() is cached at
  host->iomap and used through out LLDs.  This basically replaces
  host->mmio_base.

* if possible, pcim_iomap_regions() is used

Most iomap operation conversions are taken from Jeff Garzik
<jgarzik@pobox.com>'s iomap branch.

24dc5f33ea libata: update libata LLDs to use devres
Update libata LLDs to use devres.  Core layer is already converted to
support managed LLDs.  This patch simplifies initialization and fixes
many resource related bugs in init failure and detach path.  For
example, all converted drivers now handle ata_device_add() failure
gracefully without excessive resource rollback code.

As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down.  Note that freezing is enough in many cases
and ports are automatically frozen before being detached.

77a527eadb fix CONFIG_SATA_SIS=y compile error
Static code shouldn't be used from other modules.

drivers/built-in.o: In function `sis_init_one':
sata_sis.c:(.text+0x7634cd): undefined reference to `sis_info133'
sata_sis.c:(.text+0x7634d6): undefined reference to `sis_info133'

While I was at it, I also moved the prototype of this struct to a header
file.

9b14dec5ad sata_sis: Support for PATA supports
This is quick rework of the patch Uwe proposed but using Kconfig not
ifdefs and user selection to sort out PATA support. Instead of ifdefs and
requiring the user to select both drivers the SATA driver selects the
PATA one.

For neatness I've also moved the extern into the function that uses it.

3f3e7313e4 [PATCH] sata_sis: support SiS966/966L
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.

4adccf6f44 [PATCH] sata_sis: slave support on SiS965
SiS965 and SiS180 chips must support slave mode,
SiS965L and SiS964 chips must not support slave mode.

SCR_STATUS for SATA ports in powerdown state fixed.
Now returning 0x0113 instead of 0x0117. Avoids problem
on detecting sata_sis controller.

cf0e812f0e [PATCH] sata_sis: fix flags handling for the secondary port
sis_init_one() modifies probe_ent->port_flags after allocating and
initializing it using ata_pci_init_native_mode().  This makes port_flags
for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting
in misdetection of device due to incorrectly initialized SCR access flag.

This patch make probe_ent alloc/init happen after the final port flags
value is determined.  This is fragile but probe_ent and all the related
mess are scheduled to go away soon for exactly this reason.  We just need
to hold everything together till then.

This has been spotted and diagnosed and tested by Patrick McHardy.

cca3974e48 libata: Grand renaming.
The biggest change is that ata_host_set is renamed to ata_host.

* ata_host_set			=> ata_host
* ata_probe_ent->host_flags	=> ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags	=> ata_probe_ent->_host_flags
* ata_host_stats		=> ata_port_stats
* ata_port->host		=> ata_port->scsi_host
* ata_port->host_set		=> ata_port->host
* ata_port_info->host_flags	=> ata_port_info->flags
* ata_(.*)host_set(.*)\(\)	=> ata_\1host\2()

The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose.  Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.

ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.
