      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.
      
        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"

      Wenwen Wang authored
      In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
      'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
      there is no more free channel, an error code EBUSY or ENOMEM will be
      returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
      that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
      in fs_close(). But, if fs_open() fails, there is no guarantee that
      fs_close() will be invoked.
      
      To fix this issue, deallocate 'vcc' before the error code is returned.

      caused by the previous patch ("btrfs: scrub: Require mandatory block
      group RO for dev-replace"). Hitting ENOSPC is possible and could happen
      when the block group is set read-only, preventing NOCOW writes to the
      area that's being accessed by dev-replace.
      
      This has happend with scratch devices of size 12G but not with 5G and
      20G, so this is depends on timing and other activity on the filesystem.
      The whole replace operation is restartable, the space state should be
      examined by the user in any case.
      
      The error code is propagated back to the ioctl caller so the kernel
      warning is causing false alerts.

      net: cxgb3_main: Add CAP_NET_ADMIN check to CHELSIO_GET_MEM · 3546d8f1
      Michael Ellerman authored
      The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
      adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
      cxgb_extension_ioctl().
      
      One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
      to read memory directly out of the adapter and return it to userspace.
      It's not entirely clear what the contents of the adapter memory
      contains, but the assumption is that it shouldn't be accessible to all
      users.
      
      So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
      the is_offload() check, which matches two of the other subcommands in
      the same function which also check for is_offload() and CAP_NET_ADMIN.
      
      Found by Ilja by code inspection, not tested as I don't have the
      required hardware.

      net: bcmgenet: Use netif_tx_napi_add() for TX NAPI · 148965df
      Florian Fainelli authored
      Before commit 7587935c ("net: bcmgenet: move NAPI initialization to
      ring initialization") moved the code, this used to be
      netif_tx_napi_add(), but we lost that small semantic change in the
      process, restore that.
      
      Fixes: 7587935c ("net: bcmgenet: move NAPI initialization to ring initialization")
