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.

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

before detaching from the group.

It looks like a mini PCI-Express adapter. The mPCIE connector includes USB

The card I have isn't activated yet, so I can't get a PPP session up yet, but
I have tested basic serial communication successfully in both 2.6.18 and

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.

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.

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.

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.

The driver wrongly takes the address setup time into account when calculating
the PIO recovery time -- this leads to slight overclocking of the PIO modes 0
and 1 (so, the prayers failed to help, as usual :-). Rework the code to be
calculating recovery clock count as a difference between the total cycle count
and the active count (we don't need to calculate the recovery time itself since
it's not specified for the PIO modes 0 to 2, and for modes 3 and 4 this formula
gives enough recovery time anyway in the chip's supported PCI frequency range).
This patch has been inspired by reading the datasheets and looking at what the
libata driver does; it has been compile-tested only (as usual :-) but anyway,
the new code gives the same or longer recovery times than the old one...

Use IPI for blacklisted CPUs, add parameter IPI vs LAPIC
Currently, Linux disables lapic timer for all machines with C2 and higher
C-state support.
According to Intel only specific Intel models (Banias/Dothan) are broken
in respect of not waking up from C2 with lapic.
However, I am not sure about the naming of the parameter and how it
could/should get integrated into the dyntick part
(CONFIG_GENERIC_CLOCKEVENTS). There, a more fine grained check (TSC
still running?, ..) is needed? Does this make sense (always use
CLOCK_EVT_NOTIFY_BROADCAST_ON, but use OFF if forced by use_ipi=0:
