swap: make swap discard async
swap can do cluster discard for SSD, which is good, but there are some problems here: 1. swap do the discard just before page reclaim gets a swap entry and writes the disk sectors. This is useless for high end SSD, because an overwrite to a sector implies a discard to original sector too. A discard + overwrite == overwrite. 2. the purpose of doing discard is to improve SSD firmware garbage collection. Idealy we should send discard as early as possible, so firmware can do something smart. Sending discard just after swap entry is freed is considered early compared to sending discard before write. Of course, if workload is already bound to gc speed, sending discard earlier or later doesn't make 3. block discard is a sync API, which will delay scan_swap_map() significantly. 4. Write and discard command can be executed parallel in PCIe SSD. Making swap discard async can make execution more efficiently. This patch makes swap discard async and moves discard to where swap entry is freed. Discard and write have no dependence now, so above issues can be avoided. Idealy we should do discard for any freed sectors, but some SSD discard is very slow. This patch still does discard for a whole cluster. My test does a several round of 'mmap, write, unmap', which will trigger a lot of swap discard. In a fusionio card, with this patch, the test runtime is reduced to 18% of the time without it, so around 5.5x faster.

swap: change block allocation algorithm for SSD
I'm using a fast SSD to do swap. scan_swap_map() sometimes uses up to 20~30% CPU time (when cluster is hard to find, the CPU time can be up to 80%), which becomes a bottleneck. scan_swap_map() scans a byte array to search a 256 page cluster, which is very slow. Here I introduced a simple algorithm to search cluster. Since we only care about 256 pages cluster, we can just use a counter to track if a cluster is free. Every 256 pages use one int to store the counter. If the counter of a cluster is 0, the cluster is free. All free clusters will be added to a list, so searching cluster is very efficient. With this, scap_swap_map() overhead disappears. This might help low end SD card swap too. Because if the cluster is aligned, SD firmware can do flash erase more efficiently. We only enable the algorithm for SSD. Hard disk swap isn't fast enough and has downside with the algorithm which might introduce regression (see below). The patch slightly changes which cluster is choosen. It always adds free cluster to list tail. This can help wear leveling for low end SSD too. And if no cluster found, the scan_swap_map() will do search from the end of last cluster. So if no cluster found, the scan_swap_map() will do search from the end of last free cluster, which is random. For SSD, this isn't a problem at all. Another downside is the cluster must be aligned to 256 pages, which will reduce the chance to find a cluster. I would expect this isn't a big problem for SSD because of the non-seek penality. (And this is the reason I only enable the algorithm for SSD).

mm: vmstats: track TLB flush stats on UP too
The previous patch doing vmstats for TLB flushes ("mm: vmstats: tlb flush
counters") effectively missed UP since arch/x86/mm/tlb.c is only compiled
for SMP.
UP systems do not do remote TLB flushes, so compile those counters out on
UP.
arch/x86/kernel/cpu/mtrr/generic.c calls __flush_tlb() directly. This is
probably an optimization since both the mtrr code and __flush_tlb() write
cr4. It would probably be safe to make that a flush_tlb_all() (and then
get these statistics), but the mtrr code is ancient and I'm hesitant to
touch it other than to just stick in the counters.

mm: vmstats: tlb flush counters
I was investigating some TLB flush scaling issues and realized that we do not have any good methods for figuring out how many TLB flushes we are doing. It would be nice to be able to do these in generic code, but the arch-independent calls don't explicitly specify whether we actually need to do remote flushes or not. In the end, we really need to know if we actually _did_ global vs. local invalidations, so that leaves us with few options other than to muck with the counters from arch-specific code.

Add the ability to collect I/O statistics on user-defined regions of a

dmaengine: dma_sync_wait and dma_find_channel undefined
dma_sync_wait and dma_find_channel are declared regardless of whether CONFIG_DMA_ENGINE is enabled, but calling the function without CONFIG_DMA_ENGINE enabled results "undefined reference" errors. To get around this, declare dma_sync_wait and dma_find_channel as inline functions if CONFIG_DMA_ENGINE is undefined.

VFIO updates include safer default file flags for VFIO device fds,
an external user interface exported to allow other modules to hold references to VFIO groups, a fix to test for extended config space on PCIe and PCI-x, and new hot reset interfaces for PCI devices which allows the user to do PCI bus/slot resets when all of the devices affected by the reset are owned by the user. For this last feature, the PCI bus reset interface, I depend on changes already merged from Bjorn's PCI pull request. I therefore merged my tree up to commit |

NFS client updates for Linux 3.12
Highlights include:
- Fix NFSv4 recovery so that it doesn't recover lost locks in cases such as
lease loss due to a network partition, where doing so may result in data
corruption. Add a kernel parameter to control choice of legacy behaviour
or not.

vfs: reorganize dput() memory accesses
This is me being a bit OCD after all the dentry optimization work this merge window: profiles end up showing 'dput()' as a rather expensive operation, and there were two unrelated bad reasons for that. The first reason was reading d_lockref.count for debugging purposes, which touches the lockref cacheline (for reads) before really need to. More importantly, the debugging test in question is _wrong_, and has hidden bugs. It's true that we can only sleep when the count goes down to zero, but the test as-is hides the much more subtle bug that happens if we race with somebody else deleting the file. Anyway we _will_ touch that cacheline, but let's do it for a write and in the right routine (ie in "lockref_put_or_lock()") which annotates the costs better. So remove the misleading debug code. The other was an unnecessary access to the cacheline that contains the d_lru list, just to check whether we already were on the LRU list or not. This is exactly what we have d_flags for, so that we can avoid touching extra cache lines for the common case. So just add another bit for "is this dentry on the LRU". Finally, mark the tests properly likely/unlikely, so that the common fast-paths are dense in the instruction stream. This makes the profiles look much saner.

lockref: add ability to mark lockrefs "dead"
The only actual current lockref user (dcache) uses zero reference counts even for perfectly live dentries, because it's a cache: there may not be any users, but that doesn't mean that we want to throw away the dentry. At the same time, the dentry cache does have a notion of a truly "dead" dentry that we must not even increment the reference count of, because we have pruned it and it is not valid. Currently that distinction is not visible in the lockref itself, and the dentry cache validation uses "lockref_get_or_lock()" to either get a new reference to a dentry that already had existing references (and thus cannot be dead), or get the dentry lock so that we can then verify the dentry and increment the reference count under the lock if that verification was successful. That's all somewhat complicated. This adds the concept of being "dead" to the lockref itself, by simply using a count that is negative. This allows a usage scenario where we can increment the refcount of a dentry without having to validate it, and pushing the special "we killed it" case into the lockref code. The dentry code itself doesn't actually use this yet, and it's probably too late in the merge window to do that code (the dentry_kill() code with its "should I decrement the count" logic really is pretty complex code), but let's introduce the concept at the lockref level now.

ARM: SoC board updates for 3.12
Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
but most of this is around legacy code and board support. We've found that
platform maintainers have a hard time separating all of these out and might
move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and clocksource
setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
- New backlight drivers for backlights used on Renesas shmobile platforms.
- Removal of Renesas leds driver.
- Shuffling of some of the new Broadcom platforms to give room for others in
the same mach directory. More in 2.13.

ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

ARM: SoC cleanups for 3.12
This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.
