Commit 787314c3 ("Merge tag 'iommu-updates-v3.8' of git://git./linux/kernel/git/joro/iommu") did not account for the changed header location. The headers were made local to mach-omap2 as they are specific to omap2+ only, and we wanted to get most of the #include <plat/*.h> headers fixed up anyways for the ARM multiplatform support. We attempted to avoid this kind of merge conflict early on by setting up a minimal git branch shared by the arm-soc tree and the iommu tree, but looks like we still hit a merge issue there as the branches got merged as various topic branches.

The atomic64 library uses a handful of static spin locks to implement atomic 64-bit operations on architectures without support for atomic 64-bit instructions. Unfortunately, the spinlocks are initialized in a pure initcall and that is too late for the vfs namespace code which wants to use atomic64 operations before the initcall is run. This became a problem as of commit 8823c079: "vfs: Add setns support for the mount namespace". This leads to BUG messages such as: BUG: spinlock bad magic on CPU#0, swapper/0/0 lock: atomic64_lock+0x240/0x400, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0 do_raw_spin_lock+0x158/0x198 _raw_spin_lock_irqsave+0x4c/0x58 atomic64_add_return+0x30/0x5c alloc_mnt_ns.clone.14+0x44/0xac create_mnt_ns+0xc/0x54 mnt_init+0x120/0x1d4 vfs_caches_init+0xe0/0x10c start_kernel+0x29c/0x300 coming out early on during boot when spinlock debugging is enabled. Fix this by initializing the spinlocks statically at compile time. Reported-and-tested-by:

Pull IOMMU updates from Joerg Roedel: "A few new features this merge-window. The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration.

Woodhouse, David authored
The dma_pte_free_pagetable() function will only free a page table page if it is asked to free the *entire* 2MiB range that it covers. So if a page table page was used for one or more small mappings, it's likely to end up still present in the page tables... but with no valid PTEs. This was fine when we'd only be repopulating it with 4KiB PTEs anyway but the same virtual address range can end up being reused for a *large-page* mapping. And in that case were were trying to insert the large page into the second-level page table, and getting a complaint from the sanity check in __domain_mapping() because there was already a corresponding entry. This was *relatively* harmless; it led to a memory leak of the old page table page, but no other ill-effects. Fix it by calling dma_pte_clear_range (hopefully redundant) and dma_pte_free_pagetable() before setting up the new large page. Signed-off-by:

The red-black node in the ceph osd request structure is initialized in ceph_osdc_alloc_request() using rbd_init_node(). We do need to initialize this, because in __unregister_request() we call RB_EMPTY_NODE(), which expects the node it's checking to have been initialized. But rb_init_node() is apparently overkill, and may in fact be on its way out. So use RB_CLEAR_NODE() instead.

When a connection's socket disconnects, or if there's a protocol error of some kind on the connection, a fault is signaled and the connection is reset (closed and reopened, basically). We currently get an error message on the log whenever this occurs. A ceph connection will attempt to reestablish a socket connection repeatedly if a fault occurs. This means that these error messages will get repeatedly added to the log, which is undesirable. Change the error message to be a warning, so they don't get logged by default. Signed-off-by:

On a 4GB RAM machine, where Normal zone is much smaller than DMA32 zone, the Normal zone gets fragmented in time. This requires relatively more pressure in balance_pgdat to get the zone above the required watermark. Unfortunately, the congestion_wait() call in there slows it down for a completely wrong reason, expecting that there's a lot of writeback/swapout, even when there's none (much more common). After a few days, when fragmentation progresses, this flawed logic translates to a very high CPU iowait times, even though there's no I/O congestion at all. If THP is enabled, the problem occurs sooner, but I was able to see it even on !THP kernels, just by giving it a bit more time to occur. The proper way to deal with this is to not wait, unless there's congestion. Thanks to Mel Gorman, we already have the function that perfectly fits the job. The patch was tested on a machine which nicely revealed the problem after only 1 day of uptime, and it's been working great. Signed-off-by:

Fix up three empty files in arch/cris/ by sticking placeholder comments in there to prevent the patch program from deleting them. I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch. Signed-off-by:

Documentation says that code requiring dma-buf should add it to select, so inline fallbacks are not going to be used. A link error will make it obvious what went wrong, instead of silently doing nothing at runtime. Signed-off-by:

We never really clarified if unmap could be done in atomic context. But since mapping might require sleeping, this implies mutex in use to synchronize mapping/unmapping, so unmap could sleep as well. Add a might_sleep() to clarify this. Signed-off-by:
