Merge tag 'v5.0-rc7' into patchwork
Linux 5.0-rc7 * tag 'v5.0-rc7': (1667 commits) Linux 5.0-rc7 Input: elan_i2c - add ACPI ID for touchpad in Lenovo V330-15ISK Input: st-keyscan - fix potential zalloc NULL dereference Input: apanel - switch to using brightness_set_blocking() powerpc/64s: Fix possible corruption on big endian due to pgd/pud_present() efi/arm: Revert "Defer persistent reservations until after paging_init()" arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve table sunrpc: fix 4 more call sites that were using stack memory with a scatterlist include/linux/module.h: copy __init/__exit attrs to init/cleanup_module Compiler Attributes: add support for __copy (gcc >= 9) lib/crc32.c: mark crc32_le_base/__crc32c_le_base aliases as __pure auxdisplay: ht16k33: fix potential user-after-free on module unload x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls i2c: bcm2835: Clear current buffer pointers and counts after a transfer i2c: cadence: Fix the hold bit setting drm: Use array_size() when creating lease dm thin: fix bug where bio that overwrites thin block ignores FUA Revert "exec: load_script: don't blindly truncate shebang string" Revert "gfs2: read journal in large chunks to locate the head" net: ethernet: freescale: set FEC ethtool regs version ...
