The purpose of this patch:
- Adopt the DMA API (jazzsonic, macsonic & core driver).
- Adopt the driver model (macsonic).
This part was cribbed from jazzsonic. As a consequence, macsonic once
again works as a module. Driver model is also used by the DMA calls.
- Support 16 bit cards (macsonic & core driver, also affects jazzsonic)
This code was adapted from the mac68k linux 2.2 kernel, where it has
languished for a long time.
- Support more 32-bit mac cards (macsonic)
Also from mac68k repo.
- Zero-copy buffer handling (core driver)
Provides a nice performance improvement. The new algorithm incidentally
helped to replace the old Jazz DMA code.
The patch was tested on a variety of macs (several 32-bit quadra built-in
NICs, a 16-bit LC PDS NIC and a 16-bit comm-slot NIC), and also on MIPS
Jazz.

As SII reports that only original 3112's are affected by M15W quirk,
This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk
depending on chipsets. As of yet, we don't know exactly which PCI IDs
are for original 3112, so M15W quirk is applied to all except for 3512
and 3124. Once more info is avaliable, we can change some of these
sil_3112_m15w's to sil_3112.

[PATCH libata-dev-2.6:upstream] implement ata_poll_qc_complete and use it in polling functions
Previously, libata polling functions turned irq back on and completed
qc commands without holding host lock. This creates a race condition
between the polling task and interrupts from other ports on the same
host set or spurious interrupt from itself.
This patch implements ata_poll_qc_complete which enables irq and
completes qc atomically and convert all polling functions.
Note: atapi_packet_task() didn't use to turn irq back on or clear
ATA_FLAG_NOINTR on error exits. This patch makes it use
ata_poll_qc_complete which does both.
Note: With this change, ALL invocations of ata_qc_complete() are now
done under host_set lock.

Interrupts from devices sharing the same IRQ could cause
ata_host_intr to finish commands being processed by atapi_packet_task
if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA
protocol. This is because libata interrupt handler is unaware that
interrupts are not expected during that period. This patch adds
ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not
expecting interrupts.
Note that once proper HSM is implemented for interrupt-driven PIO,
this should be merged into it and this flag will be removed.
ahci.c is a different kind of beast, so it's left alone.
* The following drivers use ata_qc_issue_prot and ata_interrupt, so
changes in libata core will do.
ata_piix sata_sil sata_svw sata_via sata_sis sata_uli
* The following drivers use ata_qc_issue_prot and custom intr handler.
They need this change to work correctly.
sata_nv sata_vsc
* The following drivers use custom issue function and intr handler.
Currently all custom issue functions don't support ATAPI, so this
change is irrelevant, updated for consistency and to avoid later
mistakes.

Patch: fix wrong HD activity control by ahci driver
The ahci driver 1.0 sets the SActive bit on every transaction,
causing the LED to light up. The SActive bit is used only for
native command queuing (NCQ) which the current driver version
doesn't implement. Resetting the SActive bit is the device's
responsibility (by sending a "Set Device Bits FIS" to the
host adapter) but this is not required in response to
non-NCQ commands, and (most) devices don't. Thus the LED
stays always on. This patch fixes the LED behavior.

I found why my G5 was crashing when using the linux-2.6 version of the
DRM + git-drm.patch from 2.6.13-rc6-mm1, but not with the CVS DRM.
The reason was that dev->agp->cant_use_aperture wasn't getting set,
and the reason for that was that <linux/version.h> no longer gets
included and the #if LINUX_VERSION_CODE < 0x020408 in drm_agpsupport.c
was going the wrong way. With this patch (and a few others) a 32-bit

A problem was reported by Grant Grundler on an HP rx8620 using IOX
Core LAN partno(A7109-6) 5701 copper NIC. The tg3 driver mistakenly
detects this NIC as having a SerDes PHY and link does not come up as a
result.
The problem was caused by an incorrectly programmed eeprom that set the
NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location.
This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a
valid PHY ID is read from the MII registers on older 570x chips where
the MII interface is not used on SerDes chips. On newer chips such as
the 5780 that use MII for both copper and SerDes, SerDes detection must
rely on the eeprom.
This patch will make the SerDes detection identical to versions 3.25 and
older.

Rüdiger found a bug in nv_open that explains some of the reports
with duplex mismatches:
nv_open calls nv_update_link_speed for initializing the hardware link speed
registers. If current link setting matches the values in np->linkspeed and
np->duplex, then the function does nothing.
Usually, doing nothing is the right thing, but not in nv_open: During
nv_open, the registers must be initialized because the nic was reset.
The attached patch fixes that by setting np->linkspeed to an invalid value
before calling nv_update_link_speed from nv_open.
