Merge tag 'mips_4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS updates from James Hogan: "These are the main MIPS changes for 4.18. Rough overview: - MAINTAINERS: Add Paul Burton as MIPS co-maintainer - Misc: Generic compiler intrinsics, Y2038 improvements, Perf+MT fixes - Platform support: Netgear WNR1000 V3, Microsemi Ocelot integrated switch, Ingenic watchdog cleanups More detailed summary: Maintainers: - Add Paul Burton as MIPS co-maintainer, as I soon won't have access to much MIPS hardware, nor enough time to properly maintain MIPS on my own. Miscellaneous: - Use generic GCC library routines from lib/ - Add notrace to generic ucmpdi2 implementation - Rename compiler intrinsic selects to GENERIC_LIB_* - vmlinuz: Use generic ashldi3 - y2038: Convert update/read_persistent_clock() to *_clock64() - sni: Remove read_persistent_clock() - perf: Fix perf with MT counting other threads - Probe for per-TC perf counters in cpu-probe.c - Use correct VPE ID for VPE tracing Minor cleanups: - Avoid unneeded built-in.a in DTS dirs - sc-debugfs: Re-use kstrtobool_from_user - memset.S: Reinstate delay slot indentation - VPE: Fix spelling "uneeded" -> "Unneeded" Platform support: BCM47xx: - Add support for Netgear WNR1000 V3 - firmware: Support small NVRAM partitions - Use __initdata for LEDs platform data Ingenic: - Watchdog driver & platform code improvements: - Disable clock after stopping counter - Use devm_* functions - Drop module remove function - Move platform reset code to restart handler in driver - JZ4740: Convert watchdog instantiation to DT - JZ4780: Fix watchdog DT node - qi_lb60_defconfig: Enable watchdog driver Microsemi: - Ocelot: Add support for integrated switch - pcb123: Connect phys to ports" * tag 'mips_4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (30 commits) MAINTAINERS: Add Paul Burton as MIPS co-maintainer MIPS: ptrace: Make FPU context layout comments match reality MIPS: memset.S: Reinstate delay slot indentation MIPS: perf: Fix perf with MT counting other threads MIPS: perf: Use correct VPE ID when setting up VPE tracing MIPS: perf: More robustly probe for the presence of per-tc counters MIPS: Probe for MIPS MT perf counters per TC MIPS: mscc: Connect phys to ports on ocelot_pcb123 MIPS: mscc: Add switch to ocelot MIPS: JZ4740: Drop old platform reset code MIPS: qi_lb60: Enable the jz4740-wdt driver MIPS: JZ4780: dts: Fix watchdog node MIPS: JZ4740: dts: Add bindings for the jz4740-wdt driver watchdog: JZ4740: Drop module remove function watchdog: JZ4740: Register a restart handler watchdog: JZ4740: Use devm_* functions watchdog: JZ4740: Disable clock after stopping counter MIPS: VPE: Fix spelling mistake: "uneeded" -> "unneeded" MIPS: Re-use kstrtobool_from_user() MIPS: Convert update_persistent_clock() to update_persistent_clock64() ...
