crypto: arm64/sha-ce - implement export/import
When an ahash algorithm fallback to another ahash and that fallback is shaXXX-CE, doing export/import lead to error like this: alg: ahash: sha1-sun8i-ce export() overran state buffer on test vector 0, cfg=\"import/export\" This is due to the descsize of shaxxx-ce being larger than struct shaxxx_state off by an u32. For fixing this, let's implement export/import which rip the finalize variant instead of using generic export/import. Fixes: |

x86: mm: avoid allocating struct mm_struct on the stack
struct mm_struct is quite large (~1664 bytes) and so allocating on the stack may cause problems as the kernel stack size is small. Since ptdump_walk_pgd_level_core() was only allocating the structure so that it could modify the pgd argument we can instead introduce a pgd override in struct mm_walk and pass this down the call stack to where it is needed. Since the correct mm_struct is now being passed down, it is now also unnecessary to take the mmap_sem semaphore because ptdump_walk_pgd() will now take the semaphore on the real mm.

mm: ptdump: reduce level numbers by 1 in note_page()
Rather than having to increment the 'depth' number by 1 in ptdump_hole(),
let's change the meaning of 'level' in note_page() since that makes the
code simplier.
Note that for x86, the level numbers were previously increased by 1 in

arm64: mm: display non-present entries in ptdump
Previously the /sys/kernel/debug/kernel_page_tables file would only show lines for entries present in the page tables. However it is useful to also show non-present entries as this makes the size and level of the holes more visible. This aligns the behaviour with x86 which also shows holes.

arm64: mm: add p?d_leaf() definitions
walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arm64, we already have p?d_sect() macros which we can reuse for p?d_leaf(). pud_sect() is defined as a dummy function when CONFIG_PGTABLE_LEVELS < 3 or CONFIG_ARM64_64K_PAGES is defined. However when the kernel is configured this way then architecturally it isn't allowed to have a large page at this level, and any code using these page walking macros is implicitly relying on the page size/number of levels being the same as the kernel. So it is safe to reuse this for p?d_leaf() as it is an architectural restriction.

kbuild: rename hostprogs-y/always to hostprogs/always-y
In old days, the "host-progs" syntax was used for specifying host programs. It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m) I think this makes more sense because a host program is always a host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.

Merge branch 'cve-2019-3016' into kvm-next-5.6
From Boris Ostrovsky: The KVM hypervisor may provide a guest with ability to defer remote TLB flush when the remote VCPU is not running. When this feature is used, the TLB flush will happen only when the remote VPCU is scheduled to run again. This will avoid unnecessary (and expensive) IPIs. Under certain circumstances, when a guest initiates such deferred action, the hypervisor may miss the request. It is also possible that the guest may mistakenly assume that it has already marked remote VCPU as needing a flush when in fact that request had already been processed by the hypervisor. In both cases this will result in an invalid translation being present in a vCPU, potentially allowing accesses to memory locations in that guest's address space that should not be accessible. Note that only intra-guest memory is vulnerable. The five patches address both of these problems: 1. The first patch makes sure the hypervisor doesn't accidentally clear a guest's remote flush request 2. The rest of the patches prevent the race between hypervisor acknowledging a remote flush request and guest issuing a new one. Conflicts: arch/x86/kvm/x86.c [move from kvm_arch_vcpu_free to kvm_arch_vcpu_destroy] |

This syscall allows for the retrieval of file descriptors of a process based on its pidfd. A task needs to have ptrace_may_access() permissions with PTRACE_MODE_ATTACH_REALCREDS (suggested by Oleg and Andy) on the target. One of the main use-cases is in combination with seccomp's user notification feature. As a reminder, seccomp's user notification feature was made available in v5.0. It allows a task to retrieve a file descriptor for its seccomp filter. The file descriptor is usually handed of to a more privileged supervising process. The supervisor can then listen for syscall events caught by the seccomp filter of the supervisee and perform actions in lieu of the supervisee, usually emulating syscalls. pidfd_getfd() is needed to expand its uses. There are currently two major users that wait on pidfd_getfd() and one future user: - Netflix, Sargun said, is working on a service mesh where users should be able to connect to a dns-based VIP. When a user connects to e.g. 1.2.3.4:80 that runs e.g. service "foo" they will be redirected to an envoy process. This service mesh uses seccomp user notifications and pidfd to intercept all connect calls and instead of connecting them to 1.2.3.4:80 connects them to e.g. 127.0.0.1:8080. - LXD uses the seccomp notifier heavily to intercept and emulate mknod() and mount() syscalls for unprivileged containers/processes. With pidfd_getfd() more uses-cases e.g. bridging socket connections will be possible. - The patchset has also seen some interest from the browser corner. Right now, Firefox is using a SECCOMP_RET_TRAP sandbox managed by a broker process. In the future glibc will start blocking all signals during dlopen() rendering this type of sandbox impossible. Hence, in the future Firefox will switch to a seccomp-user-nofication based sandbox which also makes use of file descriptor retrieval. The thread for this can be found at https://sourceware.org/ml/libc-alpha/2019-12/msg00079.html With pidfd_getfd() it is e.g. possible to bridge socket connections for the supervisee (binding to a privileged port) and taking actions on file descriptors on behalf of the supervisee in general. Sargun's first version was using an ioctl on pidfds but various people pushed for it to be a proper syscall which he duely implemented as well over various review cycles. Selftests are of course included. I've also added instructions how to deal with merge conflicts below. There's also a small fix coming from the kernel mentee project to correctly annotate struct sighand_struct with __rcu to fix various sparse warnings. We've received a few more such fixes and even though they are mostly trivial I've decided to postpone them until after -rc1 since they came in rather late and I don't want to risk introducing build warnings. Finally, there's a new prctl() command PR_{G,S}ET_IO_FLUSHER which is needed to avoid allocation recursions triggerable by storage drivers that have userspace parts that run in the IO path (e.g. dm-multipath, iscsi, etc). These allocation recursions deadlock the device. The new prctl() allows such privileged userspace components to avoid allocation recursions by setting the PF_MEMALLOC_NOIO and PF_LESS_THROTTLE flags. The patch carries the necessary acks from the relevant maintainers and is routed here as part of prctl() thread-management." * tag 'threads-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: prctl: PR_{G,S}ET_IO_FLUSHER to support controlling memory reclaim sched.h: Annotate sighand_struct with __rcu test: Add test for pidfd getfd arch: wire up pidfd_getfd syscall pid: Implement pidfd_getfd syscall vfs, fdtable: Add fget_task helper |

I'm afraid that the rest of namei stuff will have to wait - it got zero review the last time I'd posted #work.namei, and there had been a leak in the posted series I'd caught only last weekend. I was going to repost it on Monday, but the window opened and the odds of getting any review during that... Oh, well. Anyway, openat2 part should be ready; that _did_ get sane amount of review and public testing, so here it comes" From Aleksa's description of the series: "For a very long time, extending openat(2) with new features has been incredibly frustrating. This stems from the fact that openat(2) is possibly the most famous counter-example to the mantra "don't silently accept garbage from userspace" -- it doesn't check whether unknown flags are present[1]. This means that (generally) the addition of new flags to openat(2) has been fraught with backwards-compatibility issues (O_TMPFILE has to be defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old kernels gave errors, since it's insecure to silently ignore the flag[2]). All new security-related flags therefore have a tough road to being added to openat(2). Furthermore, the need for some sort of control over VFS's path resolution (to avoid malicious paths resulting in inadvertent breakouts) has been a very long-standing desire of many userspace applications. This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum project[5]) with a few additions and changes made based on the previous discussion within [6] as well as others I felt were useful. In line with the conclusions of the original discussion of AT_NO_JUMPS, the flag has been split up into separate flags. However, instead of being an openat(2) flag it is provided through a new syscall openat2(2) which provides several other improvements to the openat(2) interface (see the patch description for more details). The following new LOOKUP_* flags are added: LOOKUP_NO_XDEV: Blocks all mountpoint crossings (upwards, downwards, or through absolute links). Absolute pathnames alone in openat(2) do not trigger this. Magic-link traversal which implies a vfsmount jump is also blocked (though magic-link jumps on the same vfsmount are permitted). LOOKUP_NO_MAGICLINKS: Blocks resolution through /proc/$pid/fd-style links. This is done by blocking the usage of nd_jump_link() during resolution in a filesystem. The term "magic-links" is used to match with the only reference to these links in Documentation/, but I'm happy to change the name. It should be noted that this is different to the scope of ~LOOKUP_FOLLOW in that it applies to all path components. However, you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it will *not* fail (assuming that no parent component was a magic-link), and you will have an fd for the magic-link. In order to correctly detect magic-links, the introduction of a new LOOKUP_MAGICLINK_JUMPED state flag was required. LOOKUP_BENEATH: Disallows escapes to outside the starting dirfd's tree, using techniques such as ".." or absolute links. Absolute paths in openat(2) are also disallowed. Conceptually this flag is to ensure you "stay below" a certain point in the filesystem tree -- but this requires some additional to protect against various races that would allow escape using "..". Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it can trivially beam you around the filesystem (breaking the protection). In future, there might be similar safety checks done as in LOOKUP_IN_ROOT, but that requires more discussion. In addition, two new flags are added that expand on the above ideas: LOOKUP_NO_SYMLINKS: Does what it says on the tin. No symlink resolution is allowed at all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an fd for the symlink as long as no parent path had a symlink component. LOOKUP_IN_ROOT: This is an extension of LOOKUP_BENEATH that, rather than blocking attempts to move past the root, forces all such movements to be scoped to the starting point. This provides chroot(2)-like protection but without the cost of a chroot(2) for each filesystem operation, as well as being safe against race attacks that chroot(2) is not. If a race is detected (as with LOOKUP_BENEATH) then an error is generated, and similar to LOOKUP_BENEATH it is not permitted to cross magic-links with LOOKUP_IN_ROOT. The primary need for this is from container runtimes, which currently need to do symlink scoping in userspace[7] when opening paths in a potentially malicious container. There is a long list of CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT (such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a few). In order to make all of the above more usable, I'm working on libpathrs[8] which is a C-friendly library for safe path resolution. It features a userspace-emulated backend if the kernel doesn't support openat2(2). Hopefully we can get userspace to switch to using it, and thus get openat2(2) support for free once it's ready. Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes though stale NFS handles)" * 'work.openat2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: Documentation: path-lookup: include new LOOKUP flags selftests: add openat2(2) selftests open: introduce openat2(2) syscall namei: LOOKUP_{IN_ROOT,BENEATH}: permit limited ".." resolution namei: LOOKUP_IN_ROOT: chroot-like scoped resolution namei: LOOKUP_BENEATH: O_BENEATH-like scoped resolution namei: LOOKUP_NO_XDEV: block mountpoint crossing namei: LOOKUP_NO_MAGICLINKS: block magic-link resolution namei: LOOKUP_NO_SYMLINKS: block symlink resolution namei: allow set_root() to produce errors namei: allow nd_jump_link() to produce errors nsfs: clean-up ns_get_path() signature to return int namei: only return -ECHILD from follow_dotdot_rcu() |

The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts: The affinity of managed interrupts is completely controlled by the kernel and user space has no influence on them. The reason is that the automatically assigned affinity correlates to the multi-queue CPU handling of block devices. If the generated affinity mask spaws both housekeeping and isolated CPUs the interrupt could be routed to an isolated CPU which would then be disturbed by I/O submitted by a housekeeping CPU. The new mechamism ensures that as long as one housekeeping CPU is online in the assigned affinity mask the interrupt is routed to a housekeeping CPU. If there is no online housekeeping CPU in the affinity mask, then the interrupt is routed to an isolated CPU to keep the device queue intact, but unless the isolated CPU submits I/O by itself these interrupts are not raised. - A small addon to the device tree irqdomain core code to avoid duplication in irq chip drivers - Conversion of the SiFive PLIC to hierarchical domains - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP INTMUX, Meson A1 GPIO - The first cut of support for the new ARM GICv4.1 - The usual pile of fixes and improvements in core and driver code -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl4vcbETHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoezyEADBPf0ipu5+KeTtCR+DjRAO8o0wM0J/ JNkRkSrS/qENSda/d6pZE2AWpqlDOs6apg+SNGkv0knM+1Xy94nLOf4zJBsR+GW0 w2jw68egnyB2QZtm/BvOJL+qCoixcObg5sLt0165pDdKzyDNWeCMtRU+QAw42T/l WC2QrhjKKqYST1m+UgDf1UXz8TDGIW4muRP9UiG0Uwc0LU6cG2H4OmGn0bYissaT JTG75pzGqUH3kZ1a1qD28nGyoY85BXz1iV5/IvIPaQbkQARbvfMbh1KvAnGhJj7N 96rjMpOGv2/kv1FI+4FUy6w5Wn4EyW2OaCtB/oUCFNcZvrNNgvglxCRQkkO8yb3D VOOm595ICm3EnIfxBpSzhgvVl5MY39g6qRb6Rpnna+8eRtrYnytMBdvhY0OGlG8/ cZYZDay0nzhY6vq023iw1YMDKqft7TR1R+6w1iPL7nXHXW99Dhv87d1Fjt0CqphD NIoNDgxciIyfMbMBvcg1qPe/g3L8+cAKNzGsIwIU9GneEZFBk3/piGcBlFpoEEOK 2QKvks3QRXMx+qVWkIqy3LZKV9EAQlb9Lpjaa1ec5d4m/EdACm19OpZpqoCljPtw 9vdaMz4ZxvUbwjih3VnVPklZCiVGiKj1j0iw5v3FCHh4MUljzCrxNMqK/U9CR8H0 uid3EX8YMi+DXA== =E2VR -----END PGP SIGNATURE----- Merge tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "The interrupt departement provides: - A mechanism to shield isolated tasks from managed interrupts: The affinity of managed interrupts is completely controlled by the kernel and user space has no influence on them.

If there is no online housekeeping CPU in the affinity mask, then the interrupt is routed to an isolated CPU to keep the device queue intact, but unless the isolated CPU submits I/O by itself these interrupts are not raised. - A small addon to the device tree irqdomain core code to avoid duplication in irq chip drivers - Conversion of the SiFive PLIC to hierarchical domains - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP INTMUX, Meson A1 GPIO - The first cut of support for the new ARM GICv4.1 - The usual pile of fixes and improvements in core and driver code" * tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) genirq, sched/isolation: Isolate from handling managed interrupts irqchip/gic-v4.1: Allow direct invalidation of VLPIs irqchip/gic-v4.1: Suppress per-VLPI doorbell irqchip/gic-v4.1: Add VPE INVALL callback irqchip/gic-v4.1: Add VPE eviction callback irqchip/gic-v4.1: Add VPE residency callback irqchip/gic-v4.1: Add mask/unmask doorbell callbacks irqchip/gic-v4.1: Plumb skeletal VPE irqchip irqchip/gic-v4.1: Implement the v4.1 flavour of VMOVP irqchip/gic-v4.1: Don't use the VPE proxy if RVPEID is set irqchip/gic-v4.1: Implement the v4.1 flavour of VMAPP irqchip/gic-v4.1: VPE table (aka GICR_VPROPBASER) allocation irqchip/gic-v3: Add GICv4.1 VPEID size discovery irqchip/gic-v3: Detect GICv4.1 supporting RVPEID irqchip/gic-v3-its: Fix get_vlpi_map() breakage with doorbells irqdomain: Fix a memory leak in irq_domain_push_irq() irqchip: Add NXP INTMUX interrupt multiplexer support dt-bindings: interrupt-controller: Add binding for NXP INTMUX interrupt multiplexer irqchip: Define EXYNOS_IRQ_COMBINER irqchip/meson-gpio: Add support for meson a1 SoCs ... |

The timekeeping and timers departement provides:
- Time namespace support: If a container migrates from one host to another then it expects that clocks based on MONOTONIC and BOOTTIME are not subject to disruption. Due to different boot time and non-suspended runtime these clocks can differ significantly on two hosts, in the worst case time goes backwards which is a violation of the POSIX requirements. The time namespace addresses this problem. It allows to set offsets for clock MONOTONIC and BOOTTIME once after creation and before tasks are associated with the namespace. These offsets are taken into account by timers and timekeeping including the VDSO. Offsets for wall clock based clocks (REALTIME/TAI) are not provided by this mechanism. While in theory possible, the overhead and code complexity would be immense and not justified by the esoteric potential use cases which were discussed at Plumbers '18. The overhead for tasks in the root namespace (host time offsets = 0) is in the noise and great effort was made to ensure that especially in the VDSO. If time namespace is disabled in the kernel configuration the code is compiled out. Kudos to Andrei Vagin and Dmitry Sofanov who implemented this feature and kept on for more than a year addressing review comments, finding better solutions. A pleasant experience. - Overhaul of the alarmtimer device dependency handling to ensure that the init/suspend/resume ordering is correct. - A new clocksource/event driver for Microchip PIT64 - Suspend/resume support for the Hyper-V clocksource - The usual pile of fixes, updates and improvements mostly in the driver code. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl4vbTcTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoXT2D/96iJ3G9Snn2khEQP3XS2rYmtDGw7NO m1n96falwWeGe6zreU80R2Jge5nLxQtNhRoMPLLee1GpHwRC6lvqEqgdZ4LMBrD2 JqV7Gzg8Urmdh+hpDsyTCpeEWEzoMKxiFOX8PxwctqUhM4szEe5iQg2YQsg85Jw2 vG6M93N2xwDILh4rhEMbKjo+5ZmYn7c1RQvpGOSmpKOj940W/N7H2HBsFhdaJ1Kw FW5pFv1211PaU5RV2YNb2dMeeMTT1N3e2VN4Dkadoxp47pb+725gNHEBEjmV9poG Lp4IhzGAPnj8zVD88icQZSTaK3gUHMClxprJ0Pf84WEtiH7SeGu8BPYyu77+oNDe yzcctDJNyCWXkzmaP/fe/HLc0TStbvNAJ5Tagp4BC75gzebeb4/n8RtRT0fKeDYL pxpDPKDAPU7p1JSjxiWAtshqjBycWNY3Z49bA7/VhKBhnv8BDyBPGlYd7/4xrbGr RK7DQNXJwaJaiNJ7p5PiaFxGzNyB0B9sThD/slSlEInIKb4h9YzWr0TV+NB62VnB sDcN+tpLbRPz5/5cHGGfxR0+zKWpfyai8pzbmmaXEaKssjRYwyvcac5EZdgbWpbK k7CqAjoWLA2P+tGeePNJOf5JYK6Vmdyh4clmuwM0zOiRJ9NlWUyMf3z7QYILs4RO UAI+6opYlZEPAw== =x3qT -----END PGP SIGNATURE----- Merge tag 'timers-core-2020-01-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "The timekeeping and timers departement provides: - Time namespace support: If a container migrates from one host to another then it expects that clocks based on MONOTONIC and BOOTTIME are not subject to disruption.

KVM: Move running VCPU from ARM to common code
For ring-based dirty log tracking, it will be more efficient to account
writes during schedule-out or schedule-in to the currently running VCPU.
We would like to do it even if the write doesn't use the current VCPU's
address space, as is the case for cached writes (see commit

arm64 updates for 5.6
- New architecture features * Support for Armv8.5 E0PD, which benefits KASLR in the same way as KPTI but without the overhead. This allows KPTI to be disabled on CPUs that are not affected by Meltdown, even is KASLR is enabled. * Initial support for the Armv8.5 RNG instructions, which claim to provide access to a high bandwidth, cryptographically secure hardware random number generator. As well as exposing these to userspace, we also use them as part of the KASLR seed and to seed the crng once all CPUs have come online. * Advertise a bunch of new instructions to userspace, including support for Data Gathering Hint, Matrix Multiply and 16-bit floating point. - Kexec * Cleanups in preparation for relocating with the MMU enabled * Support for loading crash dump kernels with kexec_file_load() - Perf and PMU drivers * Cleanups and non-critical fixes for a couple of system PMU drivers - FPU-less (aka broken) CPU support * Considerable fixes to support CPUs without the FP/SIMD extensions, including their presence in heterogeneous systems. Good luck finding a 64-bit userspace that handles this. - Modern assembly function annotations * Start migrating our use of ENTRY() and ENDPROC() over to the new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended to aid debuggers - Kbuild * Cleanup detection of LSE support in the assembler by introducing 'as-instr' * Remove compressed Image files when building clean targets - IP checksumming * Implement optimised IPv4 checksumming routine when hardware offload is not in use. An IPv6 version is in the works, pending testing. - Hardware errata * Work around Cortex-A55 erratum #1530923 - Shadow call stack * Work around some issues with Clang's integrated assembler not liking our perfectly reasonable assembly code * Avoid allocating the X18 register, so that it can be used to hold the shadow call stack pointer in future - ACPI * Fix ID count checking in IORT code. This may regress broken firmware that happened to work with the old implementation, in which case we'll have to revert it and try something else * Fix DAIF corruption on return from GHES handler with pseudo-NMIs - Miscellaneous * Whitelist some CPUs that are unaffected by Spectre-v2 * Reduce frequency of ASID rollover when KPTI is compiled in but inactive * Reserve a couple of arch-specific PROT flags that are already used by Sparc and PowerPC and are planned for later use with BTI on arm64 * Preparatory cleanup of our entry assembly code in preparation for moving more of it into C later on * Refactoring and cleanup -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEPxTL6PPUbjXGY88ct6xw3ITBYzQFAl4oY+IQHHdpbGxAa2Vy bmVsLm9yZwAKCRC3rHDchMFjNNfRB/4p3vax0hqaOnLRvmJPRXF31B8oPlivnr2u 6HCA9LkdU5IlrgaTNOJ/sQEqJAPOPCU7v49Ol0iYw0iKL1suUE7Ikui5VB6Uybqt YbfF5UNzfXAMs2A86TF/hzqhxw+W+lpnZX8NVTuQeAODfHEGUB1HhTLfRi9INsER wKEAuoZyuSUibxTFvji+DAq7nVRniXX7CM7tE385pxDisCMuu/7E5wOl+3EZYXWz DTGzTbHXuVFL+UFCANFEUlAtmr3dQvPFIqAwVl/CxjRJjJ7a+/G3cYLsHFPrQCjj qYX4kfhAeeBtqmHL7YFNWFwFs5WaT5UcQquFO665/+uCTWSJpORY =AIh/ -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "The changes are a real mixed bag this time around. The only scary looking one from the diffstat is the uapi change to asm-generic/mman-common.h, but this has been acked by Arnd and is actually just adding a pair of comments in an attempt to prevent allocation of some PROT values which tend to get used for arch-specific purposes. We'll be using them for Branch Target Identification (a CFI-like hardening feature), which is currently under review on the mailing list.
