The one fix didn't make the cut for 3.3, so we're putting it into v3.4. Tony tells me "There are more patches needed to make multiple smsc91x instances work, but we need to hear from people with such boards first.

2012-03-20drm/radeon/kms: reduce probe latency on digital connectorsTvrtko Ursulin
On a system with one HDMI and one VGA connector the latter causes output polling to run every ten seconds. This causes full EDID re-fetch on every poll and approx. 100ms rendering stalls are experienced by full screen page-flipping applications. Optimisation is to trust HPD sense on R600+ ASICs and to skip doing these expensive probes unless HPD sense has changed.

2012-03-19ext4: rewrite punch hole to use ext4_ext_remove_space()Lukas Czerner
This commit rewrites ext4 punch hole implementation to use ext4_ext_remove_space() instead of its home gown way of doing this via ext4_ext_map_blocks(). There are several reasons for changing this. Firstly it is quite non obvious that punching hole needs to ext4_ext_map_blocks() to punch a hole, especially given that this function should map blocks, not unmap it. It also required a lot of new code in ext4_ext_map_blocks(). Secondly the design of it is not very effective. The reason is that we are trying to punch out blocks in ext4_ext_punch_hole() in opposite direction than in ext4_ext_rm_leaf() which causes the ext4_ext_rm_leaf() to iterate through the whole tree from the end to the start to find the requested extent for every extent we are going to punch out. And finally the current implementation does not use the existing code, but bring a lot of new code, which is IMO unnecessary since there already is some infrastructure we can use. Specifically ext4_ext_remove_space(). This commit changes ext4_ext_remove_space() to accept 'end' parameter so we can not only truncate to the end of file, but also remove the space in the middle of the file (punch a hole). Moreover, because the last block to punch out, might be in the middle of the extent, we have to split the extent at 'end + 1' so ext4_ext_rm_leaf() can easily either remove the whole fist part of split extent, or change its size. ext4_ext_remove_space() is then used to actually remove the space (extents) from within the hole, instead of ext4_ext_map_blocks(). Note that this also fix the issue with punch hole, where we would forget to remove empty index blocks from the extent tree, resulting in double free block error and file system corruption. This is simply because we now use different code path, where this problem does not exist. This has been tested with fsx running for several days and xfstests, plus xfstest #251 with '-o discard' run on the loop image (which converts discard requestes into punch hole to the backing file). All of it on 1K and 4K file system block size. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2012-03-19[media] stb0899: fix the limits for signal strength valuesKlaus Schmidinger
stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock".

2012-03-19[media] em28xx: support for 2304:0242 PCTV QuatroStick (510e)Ivan Kalvachev
It is mostly copy/paste of the 520e code with setting GPIO7 removed (no LED light). I've worked on just released vanilla linux-3.3.0 kernel, so there may be 1/2 lines offset to the internal working source, but most of the code should apply cleanly. I was able to get the DVB-C working (tuned and watched TV). Haven't tested DVB-T (no signal atm). Special thanks to everybody who worked on the code and to Antti Palosaari and Devin Heitmueller who provided essential support on irc.
