libata: handle broken cable reporting

One or two ancient drives predated the cable spec and didn't sent the
valid bits for the field. I had hoped to leave this out of libata as a
piece of historical annoyance but a recent CD drive shows the same bug so
we have to import support for it.

Same concept as Bartlomiej's changes old IDE except that as we have
centralised blacklists we can avoid keeping another private table of stuff

David Brownell [Wed, 31 Oct 2007 09:37:37 +0000]
leds: bugfixes for leds-gpio

Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:

 - Do the INIT_WORK() before registering each LED, so if its trigger
   becomes immediately active it can schedule work without oopsing..

 - Use normal registration, not platform_driver_probe(), so that
   devices appearing "late" (hotplug type) can still be bound.

 - Mark the driver remove code as "__devexit", preventing oopses
   when the underlying device is removed.

These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.

PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.

A reasonably common problem with some devices is that they will
disable MSI generation when the INTX_DISABLE bit is set in the
PCI_COMMAND register.

Quirk this explicitly, guarding the pci_intx() calls in msi.c with
this quirk indication.

The first entries for this quirk are for 5714 and 5780 Tigon3 chips,
and thus we can remove the workaround code from the tg3.c driver.

David Miller [Thu, 25 Oct 2007 08:15:53 +0000]
PCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.

This is the fix for the following problem:

https://bugzilla.redhat.com/show_bug.cgi?id=227657

The bnx2 device 5706 complains about MSI not working behind a
ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem:

e3008dedff4bdc96a5f67224cd3d8d12237082a0:

"PCI: disable MSI by default on systems with Serverworks HT1000 chips"

was not entirely correct, and has been reverted.

MSI does not work on the PCIX bus because the BIOS did not set the
HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the
bridge.  We use the existing quirk_msi_ht_cap() to detect the problem
and disable MSI in all buses behind it.

piix: add support for ICH7 on Acer 5602aWLMi

In piix.c (and in ata_piix.c) are already included some patches to skip the
cable check on some laptops and to enable UDMA > 33 modes, but I've noticed
than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more
versions of this laptop).  With this simple patch I can set transfer mode
to UDMA100.

SLUB: Fix memory leak by not reusing cpu_slab

Fix the memory leak that may occur when we attempt to reuse a cpu_slab
that was allocated while we reenabled interrupts in order to be able to
grow a slab cache.

The per cpu freelist may contain objects and in that situation we may
overwrite the per cpu freelist pointer loosing objects.  This only
occurs if we find that the concurrently allocated slab fits our
allocation needs.

If we simply always deactivate the slab then the freelist will be
properly reintegrated and the memory leak will go away.

[S390] tod clock: announce clocksource as perfect

The Time of Day clock is the standard time source for s390. It is
- monotonic
- allows very fast reading
- architecture guarantees at least microsecond stepping
- available as part of the architecture

We should announce the rate of tod as 400 to be in sync with the
description found in clocksource.h:
"400-499:Perfect The ideal clocksource. A must-use where available."

This change will prefer tod over less reliable clock sources.

Fix this by adding some #ifdef's. Real fix would be to cleanup the

be quite a big patch. For the time being this is good enough.

[S390] Fix smsgiucv init on no iucv machines

smsgiucv is a driver that relies on iucv to work properly. If
iucv ans smsgiucv are compiled into the kernel and run on an
lpar the following scenario happens:
iucv is initialized early as a subsystem. It checks for z/VM and
returns with EPROTONOTSUPPORT. Later smsgiucv tries to run
driver_register with iucv_bus as bus. As this bus is not
initialized the driver core and list debugging issue several
warnings and oopses.

Solution is to let smsgiucv also check for z/VM and return
EPROTONOTSUPPORT as well.
