Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to
initialize the SPIC device. The new way to initialize (and disable) the
device comes directly from the AML code in the _CRS, _SRS and _DIS methods
from the DSDT table. This patch adds support for the new models.

ToPIC95 brides (and maybe some other too) require to use the ExCA registers
to power up the socket if a 16bit card is pluged. allow socket drivers to
set a flag so that yenta does just that. also clean up yenta_get_status()
a bit to use the new yenta_get_power() function.
Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this.
Ryan Underwood <nemesis-lists@icequake.net> said:
According to the mail that David Hinds received from a Toshiba engineer,
ToPIC95 and 97 do require this, and ToPIC100 does not. Maybe you have a
later revision.
For all chips, 16-bit cards can be enabled through ExCA. So doesn't it
make sense just to make this the default behavior for all Toshiba chips,
to avoid corner cases showing up later?
Daniel responded:
I disagree with ryan to change anything for topic97 bridges. they work.
and I couldn't find (read google) any report of a topic97 breaking on
applying power with the CB registers.
I'm having several toshba notebooks at work (and home) with topic95,97,100
bridges. Only the ones with a topic95 didn't work.

This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP.
When enabled then per-CPU watchdog threads are started, which try to run
once per second. If they get delayed for more than 10 seconds then a
callback from the timer interrupt detects this condition and prints out a
warning message and a stack dump (once per lockup incident). The feature
is otherwise non-intrusive, it doesnt try to unlock the box in any way, it
only gets the debug info out, automatically, and on all CPUs affected by
the lockup.

When handling writes to /proc/irq, current code is re-programming rte
entries directly. This is not recommended and could potentially cause
chipset's to lockup, or cause missing interrupts.
CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the
interrupt is pending. The same needs to be done for /proc/irq handling as well.
Otherwise user space irq balancers are really not doing the right thing.
- Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for
lack of a generic name.
- added move_irq out of IRQ_BALANCE, and added this same to X86_64
- Added new proc handler for write, so we can do deferred write at irq
handling time.
- Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead
it now shows only active cpu masks, or exactly what was set.
- Provided a common move_irq implementation, instead of duplicating
when using generic irq framework.
Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off.
Tested UP builds as well.
MSI testing: tbd: I have cards, need to look for a x-over cable, although I
did test an earlier version of this patch. Will test in a couple days.

ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO
modes 3 and 4. The value read from the drive, which reports support
for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd
with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the
drivers below need adjustments to comply with the way pio_mask is
used. I changed the masks from the commented values to all support
PIO4-0, since the spec mandates that PIO0-2 are supported and there's
no reason not to support PIO3 IMO.

This patch adds a driver for a new 1000 Mbit ethernet NIC. It is
integrated on the south bridge that is used for our Cell Blades.
The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.
This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.

Hi,
This patch contains the following hardware related fixes and other
miscellaneous bug fixes.
1. Updated the definition of single and double-bit ECC errors
2. Earlier we were allocating Transmit descriptors equal to
MAX_SKB_FRAGS. This was causing a boundary condition failure.
Need to allocate MAX_SKB_FRAGS+1 descriptors.
3. On some platforms(like PPC), pci_alloc_consistent() can return
a zero DMA address. Since the NIC cannot handle zero-addresses,
a workaround has been provided. Basically, we don't use such
that page. We reallocate.
4. If list_info allocation failed during driver load, check for
it during driver exit and return instead of trying to dereference
NULL pointer.
5. Increase the debug level of few non-critical debug messages.
6. Reset the card on critical ECC double errors only in case of
XframeI since XframeII can recover from such errors.
7. Print copyright message on driver load.
8. Bumped up the driver version no. to 2.0.8.1

scsi_io_completion() can be a bit noisy about certain conditions.
Previously this wasn't a problem for internally generated commands,
since they never hit it. However, since we do all SCSI commands via
bios, now they do. user CD testers like magicdev are now getting not
ready messages every time they touch the CD to see if there's anything
in it.
Fix this by making all scsi_execute commands REQ_QUIET and making
scsi_finish_io() not say anything for REQ_QUIET.

This patch adds a delay tailored for USB flash devices that are slow to
initialize their firmware. The symptom is a repeated Unit Attention with
ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5
seconds for such devices to become ready. Normal devices won't send the
repeated Unit Attention sense key and hence won't trigger the patch.
This fixes a problem with James Roberts-Thomson's USB device, and I've
seen several reports of other devices exhibiting the same symptoms --
presumably they will be helped as well.

The problem lies in the way the error handler uses TEST UNIT READY to
tell whether error recovery has succeeded. The scsi_eh_tur function
gives up after one round of retrying; after that it decides that more
error recovery is needed.
However TUR is liable to report sense data indicating a retry is needed
when in fact error recovery has succeeded. A typical example might be
SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready). The mere
fact that we were able to get a sensible reply to the TUR should indicate
that the device is working well enough to stop error recovery.
I ran across a case back in January where this happened. A CD-ROM drive
timed out the INQUIRY command, and a device reset fixed the blockage.
But then the drive kept responding with 2/4/1 -- because it was spinning
up I suppose -- until the error handler gave up and placed it offline.
If the initial INQUIRY had received the 2/4/1 instead, everything would
have worked okay. It doesn't seem reasonable for things to fail just
because the error handler had started running.
