Convert the ioremap*() preprocessor macros to real functions, moving them out of line. This allows us to kill off __arm_ioremap(), and __arm_iounmap() helpers, and remove __arm_ioremap_pfn_caller() from global view. Signed-off-by:

ioremap_wt() was added by aliasing it to ioremap_nocache(), which is a device mapping. Device mappings do not allow unaligned accesses, but it appears that GCC is able to inline its own memcpy() implementation which may use such accesses. The only user of this is pmem, which uses memcpy() on the region. Therefore, this is unsafe. We must implement ioremap_wt() correctly for ARM, or not at all. This patch adds a more correct implementation by re-using ioremap_wc() to provide a normal-memory non-cacheable mapping. Signed-off-by:

In a dfs setup where the client transitions from a server which supports posix paths to a server which doesn't support posix paths, the flag CIFS_MOUNT_POSIX_PATHS is not reset. This leads to the wrong directory separator being used causing smb commands to fail. Consider the following case where a dfs share on a samba server points to a share on windows smb server. # mount -t cifs -o .. //vm140-31/dfsroot/testwin/ # ls -l /mnt; touch /mnt/a total 0 touch: cannot touch ‘/mnt/a’: No such file or directory Signed-off-by:

This patch restores the slab creation sequence that was broken by commit 4066c33d and also reverts the portions that introduced the KMALLOC_LOOP_XXX macros. Those can never really work since the slab creation is much more complex than just going from a minimum to a maximum number. The latest upstream kernel boots cleanly on my machine with a 64 bit x86 configuration under KVM using either SLAB or SLUB. Fixes: 4066c33d ("support the slub_debug boot option") Reported-by:

Pull libnvdimm subsystem from Dan Williams: "The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 4 drivers / enabling modules: NFIT: Instantiates an "nvdimm bus" with the core and registers memory devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface table). After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.

Getting fantastic copy performance with cp --reflink over SMB3.11 using the new FSCTL_DUPLICATE_EXTENTS. This FSCTL was added in the SMB3.11 dialect (testing was against REFS file system) so have put it as a 3.11 protocol specific operation ("vers=3.1.1" on the mount). Tested at the SMB3 plugfest in Redmond. It depends on the new FS Attribute (BLOCK_REFCOUNTING) which is used to advertise support for the ability to do this ioctl (if you can support multiple files pointing to the same block than this refcounting ability or equivalent is needed to support the new reflink-like duplicate extent SMB3 ioctl.

gcc-4.4.4 (and possibly other versions) fail the compile when initializers are used with anonymous unions. Work around this. drivers/block/nvme-core.c: In function 'nvme_identify_ctrl': drivers/block/nvme-core.c:1163: error: unknown field 'identify' specified in initializer drivers/block/nvme-core.c:1163: warning: missing braces around initializer drivers/block/nvme-core.c:1163: warning: (near initialization for 'c.<anonymous>') drivers/block/nvme-core.c:1164: error: unknown field 'identify' specified in initializer drivers/block/nvme-core.c:1164: warning: excess elements in struct initializer drivers/block/nvme-core.c:1164: warning: (near initialization for 'c') ... This patch has no effect on text size with gcc-4.8.2.

With gcc 3.4.6/4.1.2/4.2.4 (not with 4.4.7/4.6.4/4.8.4): CC fs/block_dev.o include/linux/fs.h:804: warning: ‘I_BDEV’ declared inline after being called include/linux/fs.h:804: warning: previous declaration of ‘I_BDEV’ was here Commit a212b105 ("bdi: make inode_to_bdi() inline") added a caller of I_BDEV() in a header file, exposing the bogus "inline" on the exported implementation. Drop the "inline" keyword to fix this. Signed-off-by:

Whenever blk_fill_sghdr_rq fails, its errno code is ignored and changed to EFAULT. This can cause very confusing errors: $ sg_persist -k /dev/sda persistent reservation in: pass through os error: Bad address The fix is trivial, just propagate the return value from blk_fill_sghdr_rq. Signed-off-by:

Move gendisk deletion before controller shutdown so filesystem may sync dirty pages. Before, this would deadlock trying to allocate requests on frozen queues that are about to be deleted. Signed-off-by:

This fixes an infinite device reset loop that may occur on devices that fail initialization. If the drive fails to become ready for any reason that does not involve an admin command timeout, the probe task should assume the drive is unavailable and remove it from the topology. In the case an admin command times out during device probing, the driver's existing reset action will handle removing the drive. Signed-off-by:
