Merge tag 'mips_fixes_5.8_1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS fixes from Thomas Bogendoerfer: - fix for missing hazard barrier - DT fix for ingenic - DT fix of GPHY names for lantiq - fix usage of smp_processor_id() while preemption is enabled * tag 'mips_fixes_5.8_1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: Do not use smp_processor_id() in preemptible code MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen MIPS: ingenic: gcw0: Fix HP detection GPIO. MIPS: lantiq: xway: sysctrl: fix the GPHY clock alias names
