2012-02-28usb: dwc3: gadget: use generic map/unmap routinesFelipe Balbi
those routines have everything we need to map/unmap USB requests and it's better to use them. In order to achieve that, we had to add a simple change on how we allocate and use our setup buffer; we cannot allocate it from coherent anymore otherwise the generic map/unmap routines won't be able to easily know that the GetStatus request already has a DMA address.

2012-02-28usb: gadget: add generic map/unmap request utilitiesFelipe Balbi

2012-02-28GFS2: Read resource groups on mountSteven Whitehouse
This makes mount take slightly longer, but at the same time, the first write to the filesystem will be faster too. It also means that if there is a problem in the resource index, then we can refuse to mount rather than having to try and report that when the first write occurs. In addition, to avoid recursive locking, we hvae to take account of instances when the rindex glock may already be held when we are trying to update the rbtree of resource groups.

2012-02-28GFS2: Ensure rindex is uptodate for fallocateBob Peterson
This patch fixes a problem whereby gfs2_grow was failing and causing GFS2 to assert. The problem was that when GFS2's fallocate operation tried to acquire an "allocation" it made sure the rindex was up to date, and if not, it called gfs2_rindex_update. However, if the file being fallocated was the rindex itself, it was already locked at that point. By calling gfs2_rindex_update at an earlier point in time, we bring rindex up to date and thereby avoid trying to lock it when the "allocation" is acquired.

2012-02-28GFS2: Read in rindex if necessary during unlinkBob Peterson

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu The major features of this series are: - making RCU more aggressive about entering dyntick-idle mode in order to improve energy efficiency - converting a few more call_rcu()s to kfree_rcu()s - applying a number of rcutree fixes and cleanups to rcutiny - removing CONFIG_SMP #ifdefs from treercu - allowing RCU CPU stall times to be set via sysfs - adding CPU-stall capability to rcutorture - adding more RCU-abuse diagnostics - updating documentation - fixing yet more issues located by the still-ongoing top-to-bottom inspection of RCU, this time with a special focus on the CPU-hotplug code path.

If kzalloc() for TYPE_DATA failed on a given cpu, previous chunk of TYPE_INST will be leaked. Fix it. Thanks to Peter Zijlstra for suggesting this better solution.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest While demoing ktest at ELC in 2012, it was embarrassing that the make_min_config test failed to work because the snowball board I was testing it against had a config that would not build. But the make_min_config only tested the testing part and ignored build failures. The end result was a config file that would not boot.

2012-02-27ktest: Fix make_min_config test when build failsSteven Rostedt
The make_min_config does not take into account when the build fails, resulting in a invalid MIN_CONFIG .config file. When the build fails, it is ignored and the boot test is executed, using the previous built kernel. The configs that should be tested are not tested and they may be added or removed depending on the result of the last kernel that succeeded to be built. If the build fails, mark the current config as a failure and the configs that were disabled may still be needed. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2012-02-27drm/i915: Remove use of the autoreported ringbuffer HEAD positionChris Wilson
This is a revert of 6aa56062eaba67adfb247cded244fd877329588d. This was originally introduced to workaround reads of the ringbuffer registers returning 0 on SandyBridge causing hangs due to ringbuffer overflow. The root cause here was reads through the GT powerwell require the forcewake dance, something we only learnt of later. Now it appears that reading the reported head position from the HWS is returning garbage, leading once again to hangs. For example, on q35 the autoreported head reports: [ 217.975608] head now 00010000, actual 00010000 [ 436.725613] head now 00200000, actual 00200000 [ 462.956033] head now 00210000, actual 00210010 [ 485.501409] head now 00400000, actual 00400020 [ 508.064280] head now 00410000, actual 00410000 [ 530.576078] head now 00600000, actual 00600020 [ 553.273489] head now 00610000, actual 00610018 which appears reasonably sane. In contrast, if we look at snb: [ 141.970680] head now 00e10000, actual 00008238 [ 141.974062] head now 02734000, actual 000083c8 [ 141.974425] head now 00e10000, actual 00008488 [ 141.980374] head now 032b5000, actual 000088b8 [ 141.980885] head now 03271000, actual 00008950 [ 142.040628] head now 02101000, actual 00008b40 [ 142.180173] head now 02734000, actual 00009050 [ 142.181090] head now 00000000, actual 00000ae0 [ 142.183737] head now 02734000, actual 00009050 In addition, the automatic reporting of the head position is scheduled to be defeatured in the future. It has no more utility, remove it.

2012-02-27[PARISC] fix compile break caused by iomap: make IOPORT/PCI mapping ↵James Bottomley
functions conditional The problem in commit fea80311a939a746533a6d7e7c3183729d6a3faf Author: Randy Dunlap <rdunlap@xenotime.net> Date: Sun Jul 24 11:39:14 2011 -0700 iomap: make IOPORT/PCI mapping functions conditional is that if your architecture supplies pci_iomap/pci_iounmap, it expects always to supply them. Adding empty body defitions in the !CONFIG_PCI case, which is what this patch does, breaks the parisc compile because the functions become doubly defined. It took us a while to spot this, because we don't actually build !CONFIG_PCI very often (only if someone is brave enough to test the snake/asp machines). Since the note in the commit log says this is to fix a CONFIG_GENERIC_IOMAP issue (which it does because CONFIG_GENERIC_IOMAP supplies pci_iounmap only if CONFIG_PCI is set), there should actually have been a condition upon this. This should make sure no other architecture's !CONFIG_PCI compile breaks in the same way as parisc. The fix had to be updated to take account of the GENERIC_PCI_IOMAP separation.
