2017-01-26x86: LLVMLinux: Fix "incomplete type const struct x86cpu_device_id"Behan Webster1-0/+8
commit c4586256f0c440bc2bdb29d2cbb915f0ca785d26 upstream. Similar to the fix in 40413dcb7b273bda681dca38e6ff0bbb3728ef11 MODULE_DEVICE_TABLE(x86cpu, ...) expects the struct to be called struct x86cpu_device_id, and not struct x86_cpu_id which is what is used in the rest of the kernel code. Although gcc seems to ignore this error, clang fails without this define to fix the name. Code from drivers/thermal/x86_pkg_temp_thermal.c static const struct x86_cpu_id __initconst pkg_temp_thermal_ids[] = { ... }; MODULE_DEVICE_TABLE(x86cpu, pkg_temp_thermal_ids); Error from clang: drivers/thermal/x86_pkg_temp_thermal.c:577:1: error: variable has incomplete type 'const struct x86cpu_device_id' MODULE_DEVICE_TABLE(x86cpu, pkg_temp_thermal_ids); ^ include/linux/module.h:145:3: note: expanded from macro 'MODULE_DEVICE_TABLE' MODULE_GENERIC_TABLE(type##_device, name) ^ include/linux/module.h:87:32: note: expanded from macro 'MODULE_GENERIC_TABLE' extern const struct gtype##_id __mod_##gtype##_table \ ^ <scratch space>:143:1: note: expanded from here __mod_x86cpu_device_table ^ drivers/thermal/x86_pkg_temp_thermal.c:577:1: note: forward declaration of 'struct x86cpu_device_id' include/linux/module.h:145:3: note: expanded from macro 'MODULE_DEVICE_TABLE' MODULE_GENERIC_TABLE(type##_device, name) ^ include/linux/module.h:87:21: note: expanded from macro 'MODULE_GENERIC_TABLE' extern const struct gtype##_id __mod_##gtype##_table \ ^ <scratch space>:141:1: note: expanded from here x86cpu_device_id ^ 1 error generated.

2017-01-19compiler-gcc: disable -ftracer for __noclone functionssubmit/tizen/20170120.144453Paolo Bonzini1-1/+1
commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream. -ftracer can duplicate asm blocks causing compilation to fail in noclone functions. For example, KVM declares a global variable in an asm like asm("2: ... \n .pushsection data \n .global vmx_return \n vmx_return: .long 2b"); and -ftracer causes a double declaration.

2015-02-04KEYS: Move the flags representing required permission to linux/key.hDavid Howells2-3/+14
Move the flags representing required permission to linux/key.h as the perm parameter of security_key_permission() is in terms of them - and not the permissions mask flags used in key->perm. Whilst we're at it: (1) Rename them to be KEY_NEED_xxx rather than KEY_xxx to avoid collisions with symbols in uapi/linux/input.h. (2) Don't use key_perm_t for a mask of required permissions, but rather limit it to the permissions mask attached to the key and arguments related directly to that.

2015-02-04mfd: lpc_ich: Add support for iTCO v3Peter Tyser1-4/+4
Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different register layouts for the iTCO than the current v1 and v2 iTCO. Differences from previous iTCO versions include: - The ACPI space is enabled in the "ACPI base address" register instead of the "ACPI control register" - The "no reboot" functionality is set in the "Power Management Configuration" register instead of the "General Control and Status" (GCS) register or PCI configuration space. - The "ACPI Control Register" is not present on v3. The "Power Management Configuration Base Address" register resides at the same address is Avoton/Bay Trail. To differentiate these newer chipsets create a new v3 iTCO version and update the MFD driver to support them.

2015-02-04of: move graph helpers from drivers/media/v4l2-core to drivers/ofPhilipp Zabel1-0/+46
This patch moves the parsing helpers used to parse connected graphs in the device tree, like the video interface bindings documented in Documentation/devicetree/bindings/media/video-interfaces.txt, from drivers/media/v4l2-core/v4l2-of.c into drivers/of/base.c. This allows to reuse the same parser code from outside the V4L2 framework, most importantly from display drivers. The functions v4l2_of_get_next_endpoint, v4l2_of_get_remote_port, and v4l2_of_get_remote_port_parent are moved. They are renamed to of_graph_get_next_endpoint, of_graph_get_remote_port, and of_graph_get_remote_port_parent, respectively. Since there are not that many current users yet, switch all of them to the new functions right away.

2015-02-04spi: sh-msiof: Add DMA supportGeert Uytterhoeven1-0/+2
Add DMA support to the MSIOF driver using platform data. As MSIOF DMA is limited to 32-bit words (requiring byte/wordswapping for smaller wordsizes), and the group length is limited to 256 words, DMA is performed on two fixed pages, allocated and mapped at driver initialization time. Performance figures (in Mbps) on r8a7791/koelsch at different SPI clock frequencies for 1024-byte and 4096-byte transfers: 1024 bytes 4096 bytes - 3.25 MHz: PIO 2.1, DMA 2.6 | PIO 2.8, DMA 3.1 - 6.5 MHz: PIO 3.2, DMA 4.4 | PIO 5.0, DMA 5.9 - 13 MHz: PIO 4.2, DMA 6.6 | PIO 8.2, DMA 10.7 - 26 MHz: PIO 5.9, DMA 10.4 | PIO 12.4, DMA 18.4 Note that DMA is only faster than PIO for transfers that exceed the FIFO size (typically 64 words / 256 bytes). Also note that large transfers (larger than the group length for DMA, or larger than the FIFO size for PIO), should use cs-gpio (with the appropriate pinmux setup), as the hardware chipselect will be deasserted in between chunks.

2015-02-04Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König1-1/+1
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available.

2015-02-04spi: Make core DMA mapping functions generate scatterlistsMark Brown1-0/+7
We cannot unconditionally use dma_map_single() to map data for use with SPI since transfers may exceed a page and virtual addresses may not be provided with physically contiguous pages. Further, addresses allocated using vmalloc() need to be mapped differently to other addresses. Currently only the MXS driver handles all this, a few drivers do handle the possibility that buffers may not be physically contiguous which is the main potential problem but many don't even do that. Factoring this out into the core will make it easier for drivers to do a good job so if the driver is using the core DMA code then generate a scatterlist instead of mapping to a single address so do that. This code is mainly based on a combination of the existing code in the MXS and PXA2xx drivers. In future we should be able to extend it to allow the core to concatenate adjacent transfers if they are compatible, improving performance. Currently for simplicity clients are not allowed to use the scatterlist when they do DMA mapping, in the future the existing single address mappings will be replaced with use of the scatterlist most likely as part of pre-verifying transfers. This change makes it mandatory to use scatterlists when using the core DMA mapping so update the s3c64xx driver to do this when used with dmaengine. Doing so makes the code more ugly but it is expected that the old s3c-dma code can be removed very soon.

2015-02-04spi: Provide core support for full duplex devicesMark Brown1-0/+6
It is fairly common for SPI devices to require that one or both transfer directions is always active. Currently drivers open code this in various ways with varying degrees of efficiency. Start factoring this out by providing flags SPI_MASTER_MUST_TX and SPI_MASTER_MUST_RX. These will cause the core to provide buffers for the requested direction if none are specified in the underlying transfer. Currently this is fairly inefficient since we actually allocate a data buffer which may get large, support for mapping transfers using a scatterlist will allow us to avoid this for DMA based transfers.

2015-02-04spi: Provide core support for DMA mapping transfersMark Brown1-0/+18
The process of DMA mapping buffers for SPI transfers does not vary between devices so in order to save duplication of code in drivers this can be factored out into the core, allowing it to be integrated with the work that is being done on factoring out the common elements from the data path including more sharing of dmaengine code. In order to use this masters need to provide a can_dma() operation and while the hardware is prepared they should ensure that DMA channels are provided in tx_dma and rx_dma. The core will then ensure that the buffers are mapped for DMA prior to calling transfer_one_message(). Currently the cleanup on error is not complete, this needs to be improved.

As we do have other mechanisms, most embedded I2C will not need classes and for embedded it is explicitly not recommended to use them. Add a deprecation warning for drivers which want to disable class based instantiation in the near future to gain boot-up time, so users relying on this technique can switch to something better. They really should. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> (cherry picked from commit 0c176170089c3a7f2a891f9860f5cdc5f481ff78) Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

(which in turn attempted to fix a regression caused by e1760bd) When audit_krule_to_data() fills in the rules to get a listing, there was a missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID. This broke userspace by not returning the same information that was sent and expected. The rule: auditctl -a exit,never -F auid=-1 gives: auditctl -l LIST_RULES: exit,never f24=0 syscall=all when it should give: LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all Tag it so that it is reported the same way it was set. Create a new private flags audit_krule field (pflags) to store it that won't interact with the public one from the API.

2015-01-08userns: Add a knob to disable setgroups on a per user namespace basisEric W. Biederman1-0/+7
commit 9cc46516ddf497ea16e8d7cb986ae03a0f6b92f8 upstream. - Expose the knob to user space through a proc file /proc/<pid>/setgroups A value of "deny" means the setgroups system call is disabled in the current processes user namespace and can not be enabled in the future in this user namespace. A value of "allow" means the segtoups system call is enabled. - Descendant user namespaces inherit the value of setgroups from their parents. - A proc file is used (instead of a sysctl) as sysctls currently do not allow checking the permissions at open time. - Writing to the proc file is restricted to before the gid_map for the user namespace is set. This ensures that disabling setgroups at a user namespace level will never remove the ability to call setgroups from a process that already has that ability. A process may opt in to the setgroups disable for itself by creating, entering and configuring a user namespace or by calling setns on an existing user namespace with setgroups disabled. Processes without privileges already can not call setgroups so this is a noop. Prodcess with privilege become processes without privilege when entering a user namespace and as with any other path to dropping privilege they would not have the ability to call setgroups. So this remains within the bounds of what is possible without a knob to disable setgroups permanently in a user namespace. Signed-off-by: "Eric W.

commit 273d2c67c3e179adb1e74f403d1e9a06e3f841b5 upstream. setgroups is unique in not needing a valid mapping before it can be called, in the case of setgroups(0, NULL) which drops all supplemental groups. The design of the user namespace assumes that CAP_SETGID can not actually be used until a gid mapping is established. Therefore add a helper function to see if the user namespace gid mapping has been established and call that function in the setgroups permission check.

commit e0b9daeb453e602a95ea43853dc12d385558ce1f upstream. We're going to want to manipulate the migration mode for compaction in the page allocator, and currently compact_control's sync field is only a bool. Currently, we only do MIGRATE_ASYNC or MIGRATE_SYNC_LIGHT compaction depending on the value of this bool. Convert the bool to enum migrate_mode and pass the migration mode in directly. Later, we'll want to avoid MIGRATE_SYNC_LIGHT for thp allocations in the pagefault patch to avoid unnecessary latency. This also alters compaction triggered from sysfs, either for the entire system or for a node, to force MIGRATE_SYNC.

2014-11-21mm, compaction: add per-zone migration pfn cache for async compactionDavid Rientjes1-2/+3
commit 35979ef3393110ff3c12c6b94552208d3bdf1a36 upstream. Each zone has a cached migration scanner pfn for memory compaction so that subsequent calls to memory compaction can start where the previous call left off. Currently, the compaction migration scanner only updates the per-zone cached pfn when pageblocks were not skipped for async compaction. This creates a dependency on calling sync compaction to avoid having subsequent calls to async compaction from scanning an enormous amount of non-MOVABLE pageblocks each time it is called. On large machines, this could be potentially very expensive. This patch adds a per-zone cached migration scanner pfn only for async compaction. It is updated everytime a pageblock has been scanned in its entirety and when no pages from it were successfully isolated. The cached migration scanner pfn for sync compaction is updated only when called for sync compaction.

2014-11-21mm, migration: add destination page freeing callbackDavid Rientjes1-4/+7
commit 68711a746345c44ae00c64d8dbac6a9ce13ac54a upstream. Memory migration uses a callback defined by the caller to determine how to allocate destination pages. When migration fails for a source page, however, it frees the destination page back to the system. This patch adds a memory migration callback defined by the caller to determine how to free destination pages. If a caller, such as memory compaction, builds its own freelist for migration targets, this can reuse already freed memory instead of scanning additional memory. If the caller provides a function to handle freeing of destination pages, it is called when page migration fails. If the caller passes NULL then freeing back to the system will be handled as usual. This patch introduces no functional change.

2014-11-21mm: remove read_cache_page_async()Sasha Levin1-10/+0
commit 67f9fd91f93c582b7de2ab9325b6e179db77e4d5 upstream. This patch removes read_cache_page_async() which wasn't really needed anywhere and simplifies the code around it a bit. read_cache_page_async() is useful when we want to read a page into the cache without waiting for it to complete. This happens when the appropriate callback 'filler' doesn't complete its read operation and releases the page lock immediately, and instead queues a different completion routine to do that. This never actually happened anywhere in the code. read_cache_page_async() had 3 different callers: - read_cache_page() which is the sync version, it would just wait for the requested read to complete using wait_on_page_read(). - JFFS2 would call it from jffs2_gc_fetch_page(), but the filler function it supplied doesn't do any async reads, and would complete before the filler function returns - making it actually a sync read. - CRAMFS would call it using the read_mapping_page_async() wrapper, with a similar story to JFFS2 - the filler function doesn't do anything that reminds async reads and would always complete before the filler function returns. To sum it up, the code in mm/filemap.c never took advantage of having read_cache_page_async(). While there are filler callbacks that do async reads (such as the block one), we always called it with the read_cache_page(). This patch adds a mandatory wait for read to complete when adding a new page to the cache, and removes read_cache_page_async() and its wrappers.

commit e7b563bb2a6f4d974208da46200784b9c5b5a47e upstream. The radix tree hole searching code is only used for page cache, for example the readahead code trying to get a a picture of the area surrounding a fault. It sufficed to rely on the radix tree definition of holes, which is "empty tree slot". But this is about to change, though, as shadow page descriptors will be stored in the page cache after the actual pages get evicted from memory. Move the functions over to mm/filemap.c and make them native page cache operations, where they can later be adapted to handle the new definition of "page cache hole".
