36e337d024 [PATCH] libata: add NCQ blacklist entries from Silicon Image Windows driver (v2)
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 ]

4742d54fa4 2.6.21 fix lba48 bug in libata fill_result_tf()
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().

cda22aa94d b44: fix IFF_ALLMULTI handling of CAM slots
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.

348e3fd194 [PATCH] msi: synchronously mask and unmask msi-x irqs.
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.

8cc574a3c5 [SCSI]: Fix scsi_send_eh_cmnd scatterlist handling
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.

db8b22550d [BNX2]: Fix link interrupt problem.
bnx2_has_work()'s logic is flawed and can cause the driver to miss
a link event.  The fix is to compare the status block's attn_bits
and attn_bits_ack to determine if there is a link event.

Update version to 1.5.6.

fadac4060c mv643xx_eth: Fix use of uninitialized port_num field
In this driver, the default ethernet address is first set by by calling
eth_port_uc_addr_get() which reads the relevant registers of the
corresponding port as initially set by firmware. However that function
used the port_num field accessed through the private area of net_dev
before it was set.

The result was that one board I have ended up with the unicast address
set to 00:00:00:00:00:00 (only port 1 is connected on this board). The
problem appeared after commit 84dd619e4d.

This patch fixes the bug by setting mp->port_num prior to calling
eth_port_uc_get_addr().

wasn't fixed.  This patch makes new EH path do IDENTIFY backwards.

ata_dev_configure() for new devices are still performed master first.

There is a HW issue in ATI SB600 SATA that PxSERR.E should not be
set on some conditions, for example, when there is no media in SATA
CD/DVD drive or media is not ready, AHCI controller fails to execute
ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA
controller sets PxSERR.E at the
same time, which is not necessary.
    This patch is just to ignore the INTERNAL ERROR in such case.

d1985ad1da [PATCH] i2o: block IO errors on i2o disk
I2O subsystem has been broken in mainstream several months ago (after
2.6.18).  Commit 4aff5e2333 from Jens
Axboe split struct request ->flags into two parts: cmd_type and
cmd_flags.

In i2o layer this patch has replaced flag REQ_SPECIAL by the according
cmd_type.  However i2o has used REQ_SPECIAL not as command type but as
driver-specific flag for the debug purposes.  As result all i2o requests
have type "special" now, are not processed to the hardware and fail with
I/O error:

   i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
   unable to read partition table
  block-osm: device added (TID: 207): i2o/hda

The following patch removes the extra debug checks without any drawbacks and
restores the normal driver's work.

1ff100d76f [PATCH] correct slow acpi_pm rating
On Bob's machine clocksource is selecting PIT over the ACPI PM timer,
because he has the PIIX4 bug.  That bug drops the ACPI PM timers rating
to the same as the PIT, so that's why you're getting the PIT.

Realistically, the PIT is much slower then even the triple read ACPI PM,
so the de-ranking code is probably dropping it too far.

So don't drop ACPI PM quite so low if we see the PIIX4 bug.

6af11b9e82 KVM: Prevent system selectors leaking into guest on real->protected mode transition on vmx
Intel virtualization extensions do not support virtualizing real mode.  So
kvm uses virtualized vm86 mode to run real mode code.  Unfortunately, this
virtualized vm86 mode does not support the so called "big real" mode, where
the segment selector and base do not agree with each other according to the
real mode rules (base == selector << 4).

To work around this, kvm checks whether a selector/base pair violates the
virtualized vm86 rules, and if so, forces it into conformance.  On a
transition back to protected mode, if we see that the guest did not touch
a forced segment, we restore it back to the original protected mode value.

This pile of hacks breaks down if the gdt has changed in real mode, as it
can cause a segment selector to point to a system descriptor instead of a
normal data segment.  In fact, this happens with the Windows bootloader
and the qemu acpi bios, where a protected mode memcpy routine issues an
innocent 'pop %es' and traps on an attempt to load a system descriptor.

"Fix" by checking if the to-be-restored selector points at a system segment,
and if so, coercing it into a normal data segment.  The long term solution,
of course, is to abandon vm86 mode and use emulation for big real mode.

Various fixes to omap_udc, noted with some recent testing:

 - Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent()
   implementation: alloc() can be called with IRQs blocked, but since late
   last year that's no longer true for free().  This resolves really NASTY
   problems with logspamming via WARN_ON(), indicating N-page leaks.

 - Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the
   previous code only handled RECIP_INTERFACE, this version should be correct
   except for (sigh) bulk/interrupt endpoints.

 - Provide a better name for the function reporting whether the board has
   vbus sensing wired up.

GET_STATUS requests for endpoint status still acts strangely though, at least
given one flakey host doesn't always ack the first DATA packet, then the packet
that gets retransmitted doesn't have data!

513daadd15 ide: use correct IDE error recovery
IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set.
This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not
busy) and really hoses up some drives (modern drives will not be able to
recover using this error handling).  The correct thing to do is issue a SRST
followed by a SET FEATURES command.  This is what Western Digital recommends
for error recovery and what Western Digital says Windows does.  It also does
not violate the ATA spec as far as I can tell.

Bart:
* port the patch over the current tree
* undo the recalibration code removal
* send SET FEATURES command after checking for good drive status
* don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK}
  type because we need to send SET FEATURES before handling any requests
* some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before
  other commands (except IDENTIFY) so send SET FEATURES only if there are
  no pending drive->special requests
* update comments and patch description
* any bugs introduced by this patch are mine and not Suleiman's :-)

  only a bit as it seems that some BIOS-es reset ATA devices after programming

d18edcb212 [TG3]: Exit irq handler during chip reset.
On most tg3 chips, the memory enable bit in the PCI command register
gets cleared during chip reset and must be restored before accessing
PCI registers using memory cycles.  The chip does not generate
interrupt during chip reset, but the irq handler can still be called
because of irq sharing or irqpoll.  Reading a register in the irq
handler can cause a master abort in this scenario and may result in a
crash on some architectures.

Use the TG3_FLAG_CHIP_RESETTING flag to tell the irq handler to exit
without touching any registers.  The checking of the flag is in the
"slow" path of the irq handler and will not affect normal performance.
The msi handler is not shared and therefore does not require checking
the flag.

->neigh_destructor() is killed (not used), replaced with
->neigh_cleanup(), which is called when neighbor entry goes to dead
state. At this point everything is still valid: neigh->dev,
neigh->parms etc.

The device should guarantee that dead neighbor entries (neigh->dead !=
0) do not get private part initialized, otherwise nobody will cleanup
it.

I think this is enough for ipoib which is the only user of this thing.
Initialization private part of neighbor entries happens in ipib

After dvb tuner refactoring, the pllbuff has been altered such that the pll
address is now stored in buf[0].  Instead of sending buf to set_pll_input,
we should send buf+1.

e585bef815 [PATCH] i386: add command line option "local_apic_timer_c2_ok"
It turned out that it is almost impossible to trust ACPI, BIOS & Co.
regarding the C states. This was the reason to switch the local apic
timer off in C2 state already. OTOH there are sane and well behaving
systems, which get punished by that decision.

Allow the user to confirm that the local apic timer is trustworthy in C2
state. This keeps the default behaviour on the safe side.

77d8e1efea IB/ipoib: Fix thinko in packet length checks
The packet length checks in ipoib are broken: we add 4 bytes (IPoIB
encapsulation header) when sending a packet, not 20 bytes (hardware
address length) to each packet.  Therefore, if connected mode is
enabled so that the interface MTU is larger than the multicast MTU,
IPoIB may end up trying to send too-long multicast packets.  For
example, multicast is broken if a message of size 2048 bytes is sent
on an interface with UD MTU 2048, because 2048 is bigger than the real
limit of 2044 but the code tests against the wrong limit of 2060.

e07832b662 IPoIB: Fix race in detaching from mcast group before attaching
There's a race between ipoib_mcast_leave() and ipoib_mcast_join_finish()
where we can try to detach from a multicast group before we've
attached to it.  Fix this by reordering the code in ipoib_mcast_leave
to free the multicast group first, which waits for the multicast
callback thread (which calls ipoib_mcast_join_finish()) to complete
before detaching from the group.

d9c1e9a8ff [PATCH] tty: Fix two reported pid leaks
These leaks were reported by: Catalin Marinas <catalin.marians@gmail.com>
and I have been able to very by inspection they are possible.

When converting tty_io.c to store pids as struct pid pointers instead
of pid_t values it appears I overlooked two places where we stop using
the pid value.  The very obvious one is in do_tty_hangup, and the one
the less obvious one in __proc_set_tty.

When looking into the code __proc_set_tty only has pids that need to
be put because of failures of other parts of the code to properly
perform hangup processing.   Fixing the leak here in __proc_set_tty
is easy and obviously correct so I am doing that first.

Fixing the places that should be performing hangup processing is much
less obviously correct.  So those I'm aiming those patches at -mm.
for now, so the can age a while before they are merged.

ac1b714e78 KVM: MMU: Fix guest writes to nonpae pde
KVM shadow page tables are always in pae mode, regardless of the guest
setting.  This means that a guest pde (mapping 4MB of memory) is mapped
to two shadow pdes (mapping 2MB each).

When the guest writes to a pte or pde, we intercept the write and emulate it.
We also remove any shadowed mappings corresponding to the write.  Since the
mmu did not account for the doubling in the number of pdes, it removed the
wrong entry, resulting in a mismatch between shadow page tables and guest
page tables, followed shortly by guest memory corruption.

This patch fixes the problem by detecting the special case of writing to
a non-pae pde and adjusting the address and number of shadow pdes zapped
accordingly.

120b9cfddf ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config options
All modern distributions have been setting these options to "y" for ages.
(additionally "n" cases have been obsoleted for few years).  Therefore use
DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer
needed CONFIG_IDEDMA_AUTO).  This fixes DMA support for rare configurations
where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used
to enable DMA support and which were forced to PIO mode by "ide: don't allow
DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch.  There is no
functionality loss because "ide=nodma" kernel option is still available.

6f5050a96c ide: don't allow DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n
For CONFIG_IDEDMA_{ICS,PCI}_AUTO=n and/or "ide=nodma" option the host/device
are not programmed for DMA and it is also explicitly disabled by ide_set_dma()
(->ide_dma_check returns "-1").  However the code responsible for manually
enabling DMA ("hdparm -d 1") has a bug which results in DMA being erroneously
enabled - ide_set_dma() incorrectly passes "0" return value to set_using_dma().
This may work if BIOS/firmware configured the host/device for DMA and chipset
allows independent configuration of DMA/PIO modes but won't work after suspend
and is generally unsafe on many chipsets (possibly including data corruption
if the same registers are used for DMA/PIO timings).

This patch fixes kernel bugzilla bug #8169 (piix host driver fixes for
setting PIO mode exposed the problem described above).  The side-effect of
the fix is that some rare configuration may be forced to PIO mode when DMA
mode was previously used - this is addressed by the next patch which removes
CONFIG_IDEDMA_{PCI,ICS}_AUTO config option completely.

Thanks goes out to Patrick Horn for reporting the issue, narrowing it down
to the specific commit and testing the fix.  Also thanks to Sergei Shtylyov
for help in debugging the problem.
