This change fixes up saa7127_s_std() generate SECAM out, if the user has
requested a 50 Hz video standard set that only contains a request for SECAM
standards and not PAL. Only the SAA712[89] chips can generate SECAM, the

I was unclear on the burst start and end values - I couldn't figure out

The IDX stream is not started automatically with an MPEG strem if the IDX

makes the offsets in the IDX stream inaccurate for the final MPEG stream

V4L/DVB (13827): uvcvideo: Switch to a monotonic clock for V4L2 buffers timestamps
The realtime clock provided by do_gettimeofday() is affected by time
jumps caused by NTP or DST. Furthermore, preliminary investigation
showed that SMP systems the realtime clock is based on the CPU TSC,
and those could get slightly out of sync, resulting in jitter in the
timestamps depending on which processor handles the USB interrupts.
Instead of the realtime clock, use a monotonic high resolution clock to
timestamp the buffer. As this could in theory introduce a regression
with some userspace applications expecting a realtime clock timestamp,
add a module parameter to switch back to the realtime clock.
Thanks to Paulo Assis for pointing out and investigating the issue.

net: bug fix for vlan + gro issue
Traffic (tcp) doesnot start on a vlan interface when gro is enabled.
Even the tcp handshake was not taking place.
This is because, the eth_type_trans call before the netif_receive_skb
in napi_gro_finish() resets the skb->dev to napi->dev from the previously
set vlan netdev interface. This causes the ip_route_input to drop the
incoming packet considering it as a packet coming from a martian source.
I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7.
With this fix, the traffic starts and the test runs fine on both vlan
and non-vlan interfaces.

netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.
This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.

drm/nv50: fix instmem binding on IGPs to point at stolen system memory
This also modifies the unused PRAMIN PT entries to be all zeroes, can't
really recall why I used 9/0 initially, just that it didn't work for
some reason. It was likely masking a bug elsewhere that's since been
fixed.

drm/nv50: improve vram page table construction
This commit changes nouveau to construct PTEs which look very much like
the ones the binary driver creates.
I presume that filling multiple PTEs identically with length flags and
the physical address of the start of a block of VRAM is a hint to the
memory controller that it need not perform additional page table lookups
for that range of addresses.
