Merge tag 'arc-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta: - more changes for HS48 cores: supporting MMUv5, detecting new micro-arch gizmos - axs10x platform wiring up reset driver merged in this cycle - ARC perf driver optimizations * tag 'arc-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: ARC: perf: avoid vmalloc backed mmap ARCv2: perf: optimize given that num counters <= 32 ARCv2: perf: tweak overflow interrupt ARC: [plat-axs10x] DTS: Add reset controller node to manage ethernet reset ARCv2: boot log: updates for HS48: dual-issue, ECC, Loop Buffer ARCv2: Accomodate HS48 MMUv5 by relaxing MMU ver checking ARC: [plat-axs10x] auto-select AXS101 or AXS103 given the ISA config
