Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner: "A set of fixes and updates for x86: - Address a swiotlb regression which was caused by the recent DMA rework and made driver fail because dma_direct_supported() returned false - Fix a signedness bug in the APIC ID validation which caused invalid APIC IDs to be detected as valid thereby bloating the CPU possible space. - Fix inconsisten config dependcy/select magic for the MFD_CS5535 driver. - Fix a corruption of the physical address space bits when encryption has reduced the address space and late cpuinfo updates overwrite the reduced bit information with the original value. - Dominiks syscall rework which consolidates the architecture specific syscall functions so all syscalls can be wrapped with the same macros. This allows to switch x86/64 to struct pt_regs based syscalls. Extend the clearing of user space controlled registers in the entry patch to the lower registers" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic: Fix signedness bug in APIC ID validity checks x86/cpu: Prevent cpuinfo_x86::x86_phys_bits adjustment corruption x86/olpc: Fix inconsistent MFD_CS5535 configuration swiotlb: Use dma_direct_supported() for swiotlb_ops syscalls/x86: Adapt syscall_wrapper.h to the new syscall stub naming convention syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*() syscalls/core, syscalls/x86: Clean up compat syscall stub naming convention syscalls/core, syscalls/x86: Clean up syscall stub naming convention syscalls/x86: Extend register clearing on syscall entry to lower registers syscalls/x86: Unconditionally enable 'struct pt_regs' based syscalls on x86_64 syscalls/x86: Use 'struct pt_regs' based syscall calling for IA32_EMULATION and x32 syscalls/core: Prepare CONFIG_ARCH_HAS_SYSCALL_WRAPPER=y for compat syscalls syscalls/x86: Use 'struct pt_regs' based syscall calling convention for 64-bit syscalls syscalls/core: Introduce CONFIG_ARCH_HAS_SYSCALL_WRAPPER=y x86/syscalls: Don't pointlessly reload the system call number x86/mm: Fix documentation of module mapping range with 4-level paging x86/cpuid: Switch to 'static const' specifier |

The large diff this time around is from the addition of a new clk driver
for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well.

clang-format: add configuration file
clang-format is a tool to format C/C++/... code according to a set of rules and heuristics. Like most tools, it is not perfect nor covers every single case, but it is good enough to be helpful. In particular, it is useful for quickly re-formatting blocks of code automatically, for reviewing full files in order to spot coding style mistakes, typos and possible improvements. It is also handy for sorting ``#includes``, for aligning variables and macros, for reflowing text and other similar tasks. It also serves as a teaching tool/guide for newcomers. The tool itself has been already included in the repositories of popular Linux distributions for a long time. The rules in this file are intended for clang-format >= 4, which is easily available in most distributions. This commit adds the configuration file that contains the rules that the tool uses to know how to format the code according to the kernel coding style. This gives us several advantages: * clang-format works out of the box with reasonable defaults; avoiding that everyone has to re-do the configuration. * Everyone agrees (eventually) on what is the most useful default configuration for most of the kernel. * If it becomes commonplace among kernel developers, clang-format may feel compelled to support us better. They already recognize the Linux kernel and its style in their documentation and in one of the style sub-options. Some of clang-format's features relevant for the kernel are: * Uses clang's tooling support behind the scenes to parse and rewrite the code. It is not based on ad-hoc regexps. * Supports reasonably well the Linux kernel coding style. * Fast enough to be used at the press of a key. * There are already integrations (either built-in or third-party) for many common editors used by kernel developers (e.g. vim, emacs, Sublime, Atom...) that allow you to format an entire file or, more usefully, just your selection. * Able to parse unified diffs -- you can, for instance, reformat only the lines changed by a git commit. * Able to reflow text comments as well. * Widely supported and used by hundreds of developers in highly complex projects and organizations (e.g. the LLVM project itself, Chromium, WebKit, Google, Mozilla...). Therefore, it will be supported for a long time.

taint: add taint for randstruct
Since the randstruct plugin can intentionally produce extremely unusual kernel structure layouts (even performance pathological ones), some maintainers want to be able to trivially determine if an Oops is coming from a randstruct-built kernel, so as to keep their sanity when debugging. This adds the new flag and initializes taint_mask immediately when built with randstruct.

mm/page_alloc: don't reserve ZONE_HIGHMEM for ZONE_MOVABLE request
Freepage on ZONE_HIGHMEM doesn't work for kernel memory so it's not that important to reserve. When ZONE_MOVABLE is used, this problem would theorectically cause to decrease usable memory for GFP_HIGHUSER_MOVABLE allocation request which is mainly used for page cache and anon page allocation. So, fix it by setting 0 to sysctl_lowmem_reserve_ratio[ZONE_HIGHMEM]. And, defining sysctl_lowmem_reserve_ratio array by MAX_NR_ZONES - 1 size makes code complex. For example, if there is highmem system, following reserve ratio is activated for *NORMAL ZONE* which would be easyily misleading people. #ifdef CONFIG_HIGHMEM 32 #endif This patch also fixes this situation by defining sysctl_lowmem_reserve_ratio array by MAX_NR_ZONES and place "#ifdef" to right place.

This completes support for --image-format 2. - CephFS quota support (Luis Henriques and Zheng Yan). This set is based on the new SnapRealm code in the upcoming v13.y.z ("Mimic") release. Quota handling will be rejected on older filesystems. - memory usage improvements in CephFS (Chengguang Xu).

libnvdimm for 4.17
* A rework of the filesytem-dax implementation provides for detection of
unmap operations (truncate / hole punch) colliding with in-progress
device-DMA. A fix for these collisions remains a work-in-progress
pending resolution of truncate latency and starvation regressions.
* The of_pmem driver expands the users of libnvdimm outside of x86 and
ACPI to describe an implementation of persistent memory on PowerPC with
Open Firmware / Device tree.
* Address Range Scrub (ARS) handling is completely rewritten to account for
the fact that ARS may run for 100s of seconds and there is no platform
defined way to cancel it. ARS will now no longer block namespace
initialization.
* The NVDIMM Namespace Label implementation is updated to handle label
areas as small as 1K, down from 128K.
* Miscellaneous cleanups and updates to unit test infrastructure.

The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files.

afs: Implement @sys substitution handling
Implement the AFS feature by which @sys at the end of a pathname component may be substituted for one of a list of values, typically naming the operating system. Up to 16 alternatives may be specified and these are tried in turn until one works. Each network namespace has[*] a separate independent list. Upon creation of a new network namespace, the list of values is initialised[*] to a single OpenAFS-compatible string representing arch type plus "_linux26". For example, on x86_64, the sysname is "amd64_linux26". [*] Or will, once network namespace support is finalised in kAFS. The list may be set by: # for i in foo bar linux-x86_64; do echo $i; done >/proc/fs/afs/sysname for which separate writes to the same fd are amalgamated and applied on close. The LF character may be used as a separator to specify multiple items in the same write() call. The list may be cleared by: # echo >/proc/fs/afs/sysname and read by: # cat /proc/fs/afs/sysname foo bar linux-x86_64 Signed-off-by: David Howells <dhowells@redhat.com> |

syscalls/core, syscalls/x86: Clean up compat syscall stub naming convention
Tidy the naming convention for compat syscall subs. Hints which describe the purpose of the stub go in front and receive a double underscore to denote that they are generated on-the-fly by the COMPAT_SYSCALL_DEFINEx() macro. For the generic case, this means: t kernel_waitid # common C function (see kernel/exit.c) __do_compat_sys_waitid # inlined helper doing the actual work # (takes original parameters as declared) T __se_compat_sys_waitid # sign-extending C function calling inlined # helper (takes parameters of type long, # casts them to unsigned long and then to # the declared type) T compat_sys_waitid # alias to __se_compat_sys_waitid() # (taking parameters as declared), to # be included in syscall table For x86, the naming is as follows: t kernel_waitid # common C function (see kernel/exit.c) __do_compat_sys_waitid # inlined helper doing the actual work # (takes original parameters as declared) t __se_compat_sys_waitid # sign-extending C function calling inlined # helper (takes parameters of type long, # casts them to unsigned long and then to # the declared type) T __ia32_compat_sys_waitid # IA32_EMULATION 32-bit-ptregs -> C stub, # calls __se_compat_sys_waitid(); to be # included in syscall table T __x32_compat_sys_waitid # x32 64-bit-ptregs -> C stub, calls # __se_compat_sys_waitid(); to be included # in syscall table If only one of IA32_EMULATION and x32 is enabled, __se_compat_sys_waitid() may be inlined into the stub __{ia32,x32}_compat_sys_waitid().

net/fsl_pq_mdio: Allow explicit speficition of TBIPA address
This introduces a simpler and generic method for for finding (and mapping) the TBIPA register. Instead of relying of complicated logic for finding the TBIPA register address based on the MDIO or MII register block base address, which even in some cases relies on undocumented shadow registers, a second "reg" entry for the mdio bus devicetree node specifies the TBIPA register. Backwards compatibility is kept, as the existing logic is applied when only a single "reg" mapping is specified. Signed-off-by: Esben Haabendal <eha@deif.com> Signed-off-by: David S.

(2) Move the vnode ID uniquifier (equivalent to i_generation) from the auxiliary data to the index key to prevent a race between file delete and a subsequent file create seeing the same index key. (3) Need to retire cookies that correspond to files that we think got deleted on the server. Four patches to fix some things in fscache and cachefiles: (4) Fix a couple of checker warnings. (5) Correctly indicate to the end-of-operation callback whether an operation completed or was cancelled. (6) Add a check for multiple cookie relinquishment. (7) Fix a path through the asynchronous write that doesn't wake up a waiter for a page if the cache decides not to write that page, but discards it instead.

(9) Add tracepoints for fscache operation management and page wrangling. And then three development patches: (10) Attach the index key and auxiliary data to the cookie, pass this information through various fscache-netfs API functions and get rid of the callbacks to the netfs to get it. This means that the cache can get at this information, even if the netfs goes away. It also means that the cache can be lazy in updating the coherency data. (11) Pass the object data size through various fscache-netfs API rather than calling back to the netfs for it, and store the value in the object. This makes it easier to correctly resize the object, as the size is updated on writes to the cache, rather than calling back out to the netfs. (12) Maintain a catalogue of allocated cookies. This makes it possible to catch cookie collision up front rather than down in the bowels of the cache being run from a service thread from the object state machine. This will also make it possible in the future to reconnect to a cookie that's not gone dead yet because it's waiting for finalisation of the storage and also make it possible to bring cookies online if the cache is added after the cookie has been obtained" * tag 'fscache-next-20180406' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: fscache: Maintain a catalogue of allocated cookies fscache: Pass object size in rather than calling back for it fscache: Attach the index key and aux data to the cookie fscache: Add more tracepoints fscache: Add tracepoints fscache: Fix hanging wait on page discarded by writeback fscache: Detect multiple relinquishment of a cookie fscache: Pass the correct cancelled indications to fscache_op_complete() fscache, cachefiles: Fix checker warnings afs: Be more aggressive in retiring cached vnodes afs: Use the vnode ID uniquifier in the cache key not the aux data afs: Invalidate cache on server data change |
