Pull iommu updates for from Joerg Roedel: "This time the IOMMU updates are mostly cleanups or fixes. No big new features or drivers this time. In particular the changes include: - Bigger cleanup of the Domain<->IOMMU data structures and the code that manages them in the Intel VT-d driver. This makes the code easier to understand and maintain, and also easier to keep the data structures in sync. It is also a preparation step to make use of default domains from the IOMMU core in the Intel VT-d driver. - Fixes for a couple of DMA-API misuses in ARM IOMMU drivers, namely in the ARM and Tegra SMMU drivers. - Fix for a potential buffer overflow in the OMAP iommu driver's debug code - A couple of smaller fixes and cleanups in various drivers - One small new feature: Report domain-id usage in the Intel VT-d driver to easier detect bugs where these are leaked" * tag 'iommu-updates-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (83 commits) iommu/vt-d: Really use upper context table when necessary x86/vt-d: Fix documentation of DRHD iommu/fsl: Really fix init section(s) content iommu/io-pgtable-arm: Unmap and free table when overwriting with block iommu/io-pgtable-arm: Move init-fn declarations to io-pgtable.h iommu/msm: Use BUG_ON instead of if () BUG() iommu/vt-d: Access iomem correctly iommu/vt-d: Make two functions static iommu/vt-d: Use BUG_ON instead of if () BUG() iommu/vt-d: Return false instead of 0 in irq_remapping_cap() iommu/amd: Use BUG_ON instead of if () BUG() iommu/amd: Make a symbol static iommu/amd: Simplify allocation in irq_remapping_alloc() iommu/tegra-smmu: Parameterize number of TLB lines iommu/tegra-smmu: Factor out tegra_smmu_set_pde() iommu/tegra-smmu: Extract tegra_smmu_pte_get_use() iommu/tegra-smmu: Use __GFP_ZERO to allocate zeroed pages iommu/tegra-smmu: Remove PageReserved manipulation iommu/tegra-smmu: Convert to use DMA API iommu/tegra-smmu: smmu_flush_ptc() wants device addresses ...

Pull regmap updates from Mark Brown: "This has been a busy release for regmap. By far the biggest set of changes here are those from Markus Pargmann which implement support for block transfers in smbus devices. This required quite a bit of refactoring but leaves us better able to handle odd restrictions that controllers may have and with better performance on smbus. Other new features include: - Fix interactions with lockdep for nested regmaps (eg, when a device using regmap is connected to a bus where the bus controller has a separate regmap). Lockdep's default class identification is too crude to work without help. - Support for must write bitfield operations, useful for operations which require writing a bit to trigger them from Kuniori Morimoto. - Support for delaying during register patch application from Nariman Poushin. - Support for overriding cache state via the debugfs implementation from Richard Fitzgerald" * tag 'regmap-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (25 commits) regmap: fix a NULL pointer dereference in __regmap_init regmap: Support bulk reads for devices without raw formatting regmap-i2c: Add smbus i2c block support regmap: Add raw_write/read checks for max_raw_write/read sizes regmap: regmap max_raw_read/write getter functions regmap: Introduce max_raw_read/write for regmap_bulk_read/write regmap: Add missing comments about struct regmap_bus regmap: No multi_write support if bus->write does not exist regmap: Split use_single_rw internally into use_single_read/write regmap: Fix regmap_bulk_write for bus writes regmap: regmap_raw_read return error on !bus->read regulator: core: Print at debug level on debugfs creation failure regmap: Fix regmap_can_raw_write check regmap: fix typos in regmap.c regmap: Fix integertypes for register address and value regmap: Move documentation to regmap.h regmap: Use different lockdep class for each regmap init call thermal: sti: Add parentheses around bridge->ops->regmap_init call mfd: vexpress: Add parentheses around bridge->ops->regmap_init call regmap: debugfs: Fix misuse of IS_ENABLED ...

Pull libnvdimm updates from Dan Williams: "This update has successfully completed a 0day-kbuild run and has appeared in a linux-next release. The changes outside of the typical drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and the introduction of ZONE_DEVICE + devm_memremap_pages(). Summary: - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic mechanism for adding device-driver-discovered memory regions to the kernel's direct map. This facility is used by the pmem driver to enable pfn_to_page() operations on the page frames returned by DAX ('direct_access' in 'struct block_device_operations'). For now, the 'memmap' allocation for these "device" pages comes from "System RAM". Support for allocating the memmap from device memory will arrive in a later kernel. - Introduce memremap() to replace usages of ioremap_cache() and ioremap_wt(). memremap() drops the __iomem annotation for these mappings to memory that do not have i/o side effects. The replacement of ioremap_cache() with memremap() is limited to the pmem driver to ease merging the api change in v4.3. Completion of the conversion is targeted for v4.4. - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem driver, update the VFS DAX implementation and PMEM api to provide persistence guarantees for kernel operations on a DAX mapping. - Convert the ACPI NFIT 'BLK' driver to map the block apertures as cacheable to improve performance. - Miscellaneous updates and fixes to libnvdimm including support for issuing "address range scrub" commands, clarifying the optimal 'sector size' of pmem devices, a clarification of the usage of the ACPI '_STA' (status) property for DIMM devices, and other minor fixes" * tag 'libnvdimm-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (34 commits) libnvdimm, pmem: direct map legacy pmem by default libnvdimm, pmem: 'struct page' for pmem libnvdimm, pfn: 'struct page' provider infrastructure x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB add devm_memremap_pages mm: ZONE_DEVICE for "device memory" mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h dax: drop size parameter to ->direct_access() nd_blk: change aperture mapping from WC to WB nvdimm: change to use generic kvfree() pmem, dax: have direct_access use __pmem annotation dax: update I/O path to do proper PMEM flushing pmem: add copy_from_iter_pmem() and clear_pmem() pmem, x86: clean up conditional pmem includes pmem: remove layer when calling arch_has_wmb_pmem() pmem, x86: move x86 PMEM API to new pmem.h header libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option pmem: switch to devm_ allocations devres: add devm_memremap libnvdimm, btt: write and validate parent_uuid ...

When a pv-domain (including dom0) is started it tries to size it's p2m list according to the maximum possible memory amount it ever can achieve. Limit the initial maximum memory size to the architectural limit of the hardware in order to avoid overflows during remapping of memory. This problem will occur when dom0 is started with an initial memory size being a multiple of 1GB, but without specifying it's maximum memory size. The kernel must be configured without CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen.

Commit b1c9f169047b ("xen: split counting of extra memory pages...") introduced an error when dom0 was started with limited memory occurring only on some hardware. The problem arises in case dom0 is started with initial memory and maximum memory being the same. The kernel must be configured without CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen. If all of this is true and the E820 map of the machine is sparse (some areas are not covered) then the machine might crash early in the boot process. An example E820 map triggering the problem looks like this: [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009d7ff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009d800-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000e0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x00000000cf7fafff] usable [ 0.000000] BIOS-e820: [mem 0x00000000cf7fb000-0x00000000cf95ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cf960000-0x00000000cfb62fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfb63000-0x00000000cfd14fff] usable [ 0.000000] BIOS-e820: [mem 0x00000000cfd15000-0x00000000cfd61fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfd62000-0x00000000cfd6cfff] ACPI data [ 0.000000] BIOS-e820: [mem 0x00000000cfd6d000-0x00000000cfd6ffff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfd70000-0x00000000cfd70fff] usable [ 0.000000] BIOS-e820: [mem 0x00000000cfd71000-0x00000000cfea8fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cfea9000-0x00000000cfeb9fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfeba000-0x00000000cfecafff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cfecb000-0x00000000cfecbfff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfecc000-0x00000000cfedbfff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cfedc000-0x00000000cfedcfff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfedd000-0x00000000cfeddfff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cfede000-0x00000000cfee3fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x00000000cfee4000-0x00000000cfef6fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000cfef7000-0x00000000cfefffff] usable [ 0.000000] BIOS-e820: [mem 0x00000000e0000000-0x00000000efffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fec00000-0x00000000fec00fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fec10000-0x00000000fec10fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed00000-0x00000000fed00fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed40000-0x00000000fed44fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed61000-0x00000000fed70fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed80000-0x00000000fed8ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000ff000000-0x00000000ffffffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000100001000-0x000000020effffff] usable In this case the area a0000-dffff isn't present in the map.

When detecting a serial port on newer PA-RISC machines (with iosapic) we have a long way to go to find the right IRQ line, registering it, then registering the serial port and the irq handler for the serial port. During this phase spurious interrupts for the serial port may happen which then crashes the kernel because the action handler might not have been set up yet. So, basically it's a race condition between the serial port hardware and the CPU which sets up the necessary fields in the irq sructs. The main reason for this race is, that we unmask the serial port irqs too early without having set up everything properly before (which isn't easily possible because we need the IRQ number to register the serial ports). This patch is a work-around for this problem. It adds checks to the CPU irq handler to verify if the IRQ action field has been initialized already. If not, we just skip this interrupt (which isn't critical for a serial port at bootup). The real fix would probably involve rewriting all PA-RISC specific IRQ code (for CPU, IOSAPIC, GSC and EISA) to use IRQ domains with proper parenting of the irq chips and proper irq enabling along this line. This bug has been in the PA-RISC port since the beginning, but the crashes happened very rarely with currently used hardware. But on the latest machine which I bought (a C8000 workstation), which uses the fastest CPUs (4 x PA8900, 1GHz) and which has the largest possible L1 cache size (64MB each), the kernel crashed at every boot because of this race. So, without this patch the machine would currently be unuseable. For the record, here is the flow logic: 1. serial_init_chip() in 8250_gsc.c calls iosapic_serial_irq(). 2. iosapic_serial_irq() calls txn_alloc_irq() to find the irq. 3. iosapic_serial_irq() calls cpu_claim_irq() to register the CPU irq 4. cpu_claim_irq() unmasks the CPU irq (which it shouldn't!) 5. serial_init_chip() then registers the 8250 port. Problems: - In step 4 the CPU irq shouldn't have been registered yet, but after step 5 - If serial irq happens between 4 and 5 have finished, the kernel will crash Signed-off-by: Helge Deller <deller@gmx.de>

Commit 3a9ad0b4 ("PCI: Add pci_bus_addr_t") unconditionally introduced usage of 64-bit PCI bus addresses on all 64-bit platforms which broke PA-RISC. It turned out that due to enabling the 64-bit addresses, the PCI logic decided to use the GMMIO instead of the LMMIO region. This commit simply disables registering the GMMIO and thus we fall back to use the LMMIO region as before.

Deatils: - large rework of EFI/EFD lifecycle handling to fix log recovery corruption issues, crashes and unmount hangs - separate metadata UUID on disk to enable changing boot label UUID for v5 filesystems - fixes for gcc miscompilation on certain platforms and optimisation levels - remote attribute allocation and recovery corruption fixes - inode lockdep annotation rework to fix bugs with too many subclasses - directory inode locking changes to prevent lockdep false positives - a handful of minor corruption fixes - various other small cleanups and bug fixes" * tag 'xfs-for-linus-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (42 commits) xfs: fix error gotos in xfs_setattr_nonsize xfs: add mssing inode cache attempts counter increment xfs: return errors from partial I/O failures to files libxfs: bad magic number should set da block buffer error xfs: fix non-debug build warnings xfs: collapse allocsize and biosize mount option handling xfs: Fix file type directory corruption for btree directories xfs: lockdep annotations throw warnings on non-debug builds xfs: Fix uninitialized return value in xfs_alloc_fix_freelist() xfs: inode lockdep annotations broke non-lockdep build xfs: flush entire file on dio read/write to cached file xfs: Fix xfs_attr_leafblock definition libxfs: readahead of dir3 data blocks should use the read verifier xfs: stop holding ILOCK over filldir callbacks xfs: clean up inode lockdep annotations xfs: swap leaf buffer into path struct atomically during path shift xfs: relocate sparse inode mount warning xfs: dquots should be stamped with sb_meta_uuid xfs: log recovery needs to validate against sb_meta_uuid xfs: growfs not aware of sb_meta_uuid ...

The NFSv4 delegation spec allows the server to tell a client to limit how much data it cache after the file is closed. In return, the server guarantees enough free space to avoid ENOSPC situations, etc. Prior to this patch, we assumed we could always cache aggressively after close. Unfortunately, this causes problems with servers that set the limit to 0 and therefore do not offer any ENOSPC guarantees. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

Since we're tracking modifications to the page cache on a per-page basis, it makes sense to express the limit to how much we may cache in units of pages. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

I've gotten several more over the past week, but this group has been in for-next for at least a couple of weeks so I figured I'd push them first while I test the rest. Most of the ones not in this set are bug-fixes anyways so I could hold them for rc1" * tag 'for-linus-4.3-merge-window-part-1' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs: 9p: fix return code of read() when count is 0 9p: remove unused option Opt_trans
