Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM development updates from Russell King: - Make it clear __swp_entry_to_pte() uses PTE_TYPE_FAULT - Updates for setting vmalloc size via command line to resolve an issue with the 8MiB hole not properly being accounted for, and clean up the code. - ftrace support for module PLTs - Spelling fixes - kbuild updates for removing generated files and pattern rules for generating files - Clang/llvm updates - Change the way the kernel is mapped, placing it in vmalloc space instead. - Remove arm_pm_restart from arm and aarch64. * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (29 commits) ARM: 9098/1: ftrace: MODULE_PLT: Fix build problem without DYNAMIC_FTRACE ARM: 9097/1: mmu: Declare section start/end correctly ARM: 9096/1: Remove arm_pm_restart() ARM: 9095/1: ARM64: Remove arm_pm_restart() ARM: 9094/1: Register with kernel restart handler ARM: 9093/1: drivers: firmwapsci: Register with kernel restart handler ARM: 9092/1: xen: Register with kernel restart handler ARM: 9091/1: Revert "mm: qsd8x50: Fix incorrect permission faults" ARM: 9090/1: Map the lowmem and kernel separately ARM: 9089/1: Define kernel physical section start and end ARM: 9088/1: Split KERNEL_OFFSET from PAGE_OFFSET ARM: 9087/1: kprobes: test-thumb: fix for LLVM_IAS=1 ARM: 9086/1: syscalls: use pattern rules to generate syscall headers ARM: 9085/1: remove unneeded abi parameter to syscallnr.sh ARM: 9084/1: simplify the build rule of mach-types.h ARM: 9083/1: uncompress: atags_to_fdt: Spelling s/REturn/Return/ ARM: 9082/1: [v2] mark prepare_page_table as __init ARM: 9079/1: ftrace: Add MODULE_PLTS support ARM: 9078/1: Add warn suppress parameter to arm_gen_branch_link() ARM: 9077/1: PLT: Move struct plt_entries definition to header ...
