I got following warning on ia64 box:
In function 'acpi_processor_power_verify':

The problem is that the lapic_timer_propagate_broadcast() has 2 versions:
One is real code that modified in the above commit, and the other is NOP
code that used when !ARCH_APICTIMER_STOPS_ON_C3:
static void lapic_timer_propagate_broadcast(struct acpi_processor *pr) { }
So I got warning because of !ARCH_APICTIMER_STOPS_ON_C3.
We really want to do nothing here on !ARCH_APICTIMER_STOPS_ON_C3, so
modify lapic_timer_propagate_broadcast() of real version to use
smp_call_function_single() in it.

Commit 86b3728141 adds a check for
misaligned stacking offsets, but it's buggy since the defaults are 0.
Hence all dm devices that pass in a non-zero starting offset will
be marked as misaligned amd dm will complain.
A real fix is coming, in the mean time disable the discard granularity
check so that users don't worry about dm reporting about misaligned
devices.

Instead of adding a (struct dock_station **) to our dock device's
platform data, we can add the (struct dock_station *) directly.
This change saves us some ugly casting and improves readability.
The cost of making this change is an extra 290 bytes of stack usage,
but this is an infrequently called code-path and unlikely to cause
the kernel to blow up.

When the 82598 is fed 802.1q packets, it chokes with
an error of the form:
ixgbe: eth0: ixgbe_tx_csum: partial checksum but proto=81!
As the logic there was not smart enough to look into
the vlan header to pick out the encapsulated protocol.
There are times when we'd like to send these packets
out without having to configure a vlan on the interface.
Here we check for the vlan tag and allow the packet to
go out with the correct hardware checksum.

Modified patch with Dave's comments to replace mdelay with proper msleep.
Fix 82598 copper link issue, where the phy prematurely indicates link
before it is ready to process packets. The new function looks for phy
link and indicates that, when it is available. If phy is not ready
within few seconds of MAC indicating link, the function will return
failure which translates to link down indication.

Previously, if there was no firmware available, the DRM would just
disable channel creation from userspace, but still use a single
channel for its own purposes.
With a bit of care it should actually be possible to do this, due
to the DRM's very limited use of the engine. It currently doesn't
work correctly however, resulting in corrupted fbcon and hangs on
a number of cards.

The context programs are *very* simple compared to the ones used by
the binary driver. There's notes in nv40_grctx.c explaining most of
the things we don't implement. If we discover if/why any of it is
required further down the track, we'll handle it then.
The PGRAPH state generated for each chipset should match what NVIDIA
do almost exactly (there's a couple of exceptions). If someone has
a lot of time on their hands, they could figure out the mapping of
object/method to PGRAPH register and demagic the initial state a little,
it's not terribly important however.
At time of commit, confirmed to be working at least well enough for
accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46,
NV49, NV4A, NV4B and NV4E.
A module option has been added to force the use of external firmware
blobs if it becomes required.
