commit 549e15611b upstream.
MSI delivery from on-board ahci controller doesn't work on K8M800. At
this point, it's unclear whether the culprit is with the ahci
controller or the host bridge. Given the track record and considering
the rather minimal impact of MSI, disabling it seems reasonable.

There is no reason to run NVidia-specific quirks related to HT MSI
mappings with MSI disabled via pci=nomsi, so make
__nv_msi_ht_cap_quirk() return immediately in that case.
This allows at least one machine to boot 100% of the time with
pci=nomsi (it still doesn't boot reliably without that).

This patch prevents the code from calling parport_release and
parport_unregister_device twice with the same arguments - and thus fixes an oops.
Rationale:
After the first call the parport is already released and the
handle isn't valid anymore and calling parport_release and
parport_unregister_device twice isn't a good idea.

The solutions is to set preset_lpj value based on the current tsc frequency

In nvram_write, first of all, correctly handle the case where the file
pointer is already beyond the end; we should return EOF in that case.
Second, make the logic a bit more explicit so that gcc can statically
prove that the copy_from_user() is safe. Once the condition of the
beyond-end filepointer is eliminated, the copy is safe but gcc can't
prove it, causing build failures for i386 allyesconfig.
Third, eliminate the entirely superfluous variable "len", and just use

SIDPR window registers are shared across ports and as each access is
done in two steps, accesses to different ports under EH may race.
This primarily is caused by incorrect host locking in EH context and
should be fixed by defining locking requirements for each EH operation
which can be used during EH and enforcing them but for now work around
the problem by adding a dedicated SIDPR lock and grabbing it for each
SIDPR access.

commit d53cdbb94a upstream.
Attempting to read registers that don't exist on the SSB bus can cause
hangs on some boxes. At least some b43 devices are 'in the wild' that
don't have SPROMs at all. When the SSB bus support loads, it attempts
to read these (non-existant) SPROMs and causes hard hangs on the box --
no console output, etc.
This patch adds some intelligence to determine whether or not the SPROM
is present before attempting to read it. This avoids those hard hangs
on those devices with no SPROM attached to their SSB bus. The
SSB-attached devices (e.g. b43, et al.) won't work, but at least the box
will survive to test further patches. :-)

xen_sched_clock only counts unstolen time. In principle this should
be useful to the Linux scheduler so that it knows how much time a process
actually consumed. But in practice this doesn't work very well as the
scheduler expects the sched_clock time to be synchronized between
cpus. It also uses sched_clock to measure the time a task spends
sleeping, in which case "unstolen time" isn't meaningful.
So just use plain xen_clocksource_read to return wallclock nanoseconds
for sched_clock.

commit 728a756b8f upstream.
This patch fixes a kernel Oops in the GFS2 rename code.
The problem was in the way the gfs2 directory code was trying
to re-use sentinel directory entries.
In the failing case, gfs2's rename function was renaming a
file to another name that had the same non-trivial length.
The file being renamed happened to be the first directory
entry on the leaf block.
First, the rename code (gfs2_rename in ops_inode.c) found the
original directory entry and decided it could do its job by
simply replacing the directory entry with another. Therefore
it determined correctly that no block allocations were needed.
Next, the rename code deleted the old directory entry prior to
replacing it with the new name. Therefore, the soon-to-be
replaced directory entry was temporarily made into a directory
entry "sentinel" or a place holder at the start of a leaf block.
Lastly, it went to re-add the replacement directory entry in
that leaf block. However, when gfs2_dirent_find_space was
looking for space in the leaf block, it used the wrong value
for the sentinel. That threw off its calculations so later
it decides it can't really re-use the sentinel and therefore
must allocate a new leaf block. But because it previously decided
to re-use the directory entry, it didn't waste the time to
grab a new block allocation for the inode. Therefore, the
inode's i_alloc pointer was still NULL and it crashes trying to
reference it.
In the case of sentinel directory entries, the entire dirent is
reused, not just the "free space" portion of it, and therefore
the function gfs2_dirent_find_space should use the value 0
rather than GFS2_DIRENT_SIZE(0) for the actual dirent size.
Fixing this calculation enables the reproducer programs to work
properly.

When issuing a reset, the TSF value is lost in the hardware because of

Additionally, there's an issue that frequently prevents a successful

This patch detects failed TSF writes and recovers from them, taking

commit 36f2407fe5 upstream.
Should e1000_test_msi() fail to see an msi interrupt, it attempts to
fallback to legacy INTx interrupts. But an error in the code may prevent
this from happening correctly.
Before calling e1000_test_msi_interrupt(), e1000_test_msi() disables SERR
by clearing the SERR bit from the just read PCI_COMMAND bits as it writes
them back out.
Upon return from calling e1000_test_msi_interrupt(), it re-enables SERR
by writing out the version of PCI_COMMAND it had previously read.
The problem with this is that e1000_test_msi_interrupt() calls
pci_disable_msi(), which eventually ends up in pci_intx(). And because
pci_intx() was called with enable set to 1, the INTX_DISABLE bit gets
cleared from PCI_COMMAND, which is what we want. But when we get back to
e1000_test_msi(), the INTX_DISABLE bit gets inadvertently re-set because
of the attempt by e1000_test_msi() to re-enable SERR.
The solution is to have e1000_test_msi() re-read the PCI_COMMAND bits as
part of its attempt to re-enable SERR.
During debugging/testing of this issue I found that not all the systems
I ran on had the SERR bit set to begin with. And on some of the systems
the same could be said for the INTX_DISABLE bit. Needless to say these
latter systems didn't have a problem falling back to legacy INTx
interrupts with the code as is.

Several comedi drivers call subdev_8255_init() (declared in
"drivers/staging/comedi/drivers/8255.h") to set up one or more DIO
subdevices. This should be provided by the 8255.ko module, but unless
the CONFIG_COMEDI_8255 or CONFIG_COMEDI_8255_MODULE macro is defined,
the 8255.h header uses a dummy inline version of the function instead.
This means the comedi devices end up with an "unused" subdevice with 0
channels instead of a "DIO" subdevice with 24 channels!

Debian's ia64 autobuilders have been seeing kernel freeze or reboot
when running the gdb testsuite (Debian bug 588574): dannf bisected to
2.6.32 62eede62da "mm: ZERO_PAGE without
PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target.
I'd missed updating the gate_vma handling in __get_user_pages(): that
happens to use vm_normal_page() (nowadays failing on the zero page),
yet reported success even when it failed to get a page - boom when
access_process_vm() tried to copy that to its intermediate buffer.
Fix this, resisting cleanups: in particular, leave it for now reporting
success when not asked to get any pages - very probably safe to change,
but let's not risk it without testing exposure.
Why did ia64 crash with 16kB pages, but succeed with 64kB pages?
Because setup_gate() pads each 64kB of its gate area with zero pages.

commit b70f4e85bf upstream.
Typo in down_spin() meant it only read the low 32 bits of the
"serve" value, instead of the full 64 bits. This results in the
system hanging when the values in ticket/serve get larger than
32-bits. A big enough system running the right test can hit this
in a just a few hours.
