Mention the slab name when listing corrupt objects. Although the function
that released the memory is mentioned, that is frequently ambiguous as such
functions often release several pieces of memory.

This adds some NCQ blacklist entries taken from the Silicon Image 3124/3132
Windows driver .inf files. There are some confirming reports of problems
with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178)
so let's disable NCQ on these drives.
[ I'm personally starting to wonder whether we shouldn't disable NCQ by
default, and perhaps have a white-list. There seems to be a *lot* of
drives that do this wrong.. - Linus ]

Current 2.6.21 libata does the following:
void ata_tf_read(struct ata_port *ap, struct ata_taskfile *tf)
{
struct ata_ioports *ioaddr = &ap->ioaddr;
tf->command = ata_check_status(ap);
...
if (tf->flags & ATA_TFLAG_LBA48) {
iowrite8(tf->ctl | ATA_HOB, ioaddr->ctl_addr);
tf->hob_feature = ioread8(ioaddr->error_addr);
...
}
}
...
static void fill_result_tf(struct ata_queued_cmd *qc)
{
struct ata_port *ap = qc->ap;
ap->ops->tf_read(ap, &qc->result_tf);
qc->result_tf.flags = qc->tf.flags;
}
Based on this, those last two statements fill_result_tf()
appear to me to be in the wrong order, in that the tf->flags
are uninitialized at the point where tf_read() is invoked.
So for lba48 commands, tf_read() won't be reading back the
full lba48 register contents..
Correct?
This patch corrects fill_result_tf() so that the flags
get copied to result_tf before they are used by tf_read().

The irq handler schedules a NAPI poll request unconditionally as soon as

If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than
B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast
messages. This is because the __b44_set_mac_addr call sets the zeroth CAM
entry to the MAC address of the device, and then the loop at line 1722
proceeds to overwrite it unless the value of i is set by the __b44_load_mcast
call. However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set
to zero.
Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC
address.

This is a simplified and actually more comprehensive form of a bug
fix from Mitch Williams <mitch.a.williams@intel.com>.
When we mask or unmask a msi-x irqs the writes may be posted because
we are writing to memory mapped region. This means the mask and
unmask don't happen immediately but at some unspecified time in the
future. Which is out of sync with how the mask/unmask logic work
for ioapic irqs.
The practical result is that we get very subtle and hard to track down
irq migration bugs.
This patch performs a read flush after writes to the MSI-X table for mask
and unmask operations. Since the SMP affinity is set while the interrupt
is masked, and since it's unmasked immediately after, no additional flushes
are required in the various affinity setting routines.
The testing by Mitch Williams on his especially problematic system should
still be valid as I have only simplified the code, not changed the
functionality.
We currently have 7 drivers: cciss, mthca, cxgb3, forceth, s2io,
pcie/portdrv_core, and qla2xxx in 2.6.21 that are affected by this
problem when the hardware they driver is plugged into the right slot.
Given the difficulty of reproducing this bug and tracing it down to
anything that even remotely resembles a cause, even if people are
being affected we aren't likely to see many meaningful bug reports, and
the people who see this bug aren't likely to be able to reproduce this
bug in a timely fashion. So it is best to get this problem fixed
as soon as we can so people don't have problems.
Then if people do have a kernel message stating "No irq for vector" we
will know it is yet another novel cause that needs a complete new
investigation.

* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
[SCSI]: Fix scsi_send_eh_cmnd scatterlist handling
[SPARC]: Add unsigned to unused bit field in a.out.h
This fixes a regression caused by commit:
2dc611de5a
The sense buffer code in scsi_send_eh_cmnd was changed to use
alloc_page() and a scatter list, but the sense data copy was not
updated to match so what we actually get in the sense buffer is total
grabage starting with the kernel address of the struct page we got.
Basically the stack frame of scsi_send_eh_cmd() is what ends up
in the sense buffer.
Depending upon how pointers look on a given platform, you can
end up getting sr_ioctl.c errors when you mount a cdrom. If
the CDROM gives a check condition for GPCMD_GET_CONFIGURATION issued
by drivers/cdrom/cdrom.c:cdrom_mmc_profile(), sr_ioctl will
spit out this error message in sr_do_ioctl() with the way pointers
are on sparc64:
default:
printk(KERN_ERR "%s: CDROM (ioctl) error, command: ", cd->cdi.name);
__scsi_print_command(cgc->cmd);
scsi_print_sense_hdr("sr", &sshdr);
err = -EIO;
This is the error Tom Callaway reported in:
http://marc.info/?l=linux-sparc&m=117407453208101&w=2
Anyways, fix this by using page_address(sgl.page) which is OK
because we know this is low-mem due to GFP_ATOMIC.

length to 4 bytes.
The page erase code is also moved so that it is only called when
