Merge tag 'mips_fixes_5.1_3' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS fixes from Paul Burton: "A couple more MIPS fixes: - Fix indirect syscall tracing & seccomp filtering for big endian MIPS64 kernels, which previously loaded the syscall number incorrectly & would always use zero. - Fix performance counter IRQ setup for Atheros/ath79 SoCs, allowing perf to function on those systems. And not really a fix, but a useful addition: - Add a Broadcom mailing list to the MAINTAINERS entry for BMIPS systems to allow relevant engineers to track patch submissions" * tag 'mips_fixes_5.1_3' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: perf: ath79: Fix perfcount IRQ assignment MIPS: scall64-o32: Fix indirect syscall number load MAINTAINERS: BMIPS: Add internal Broadcom mailing list
