If anyone has any objections, please let me know. ------------------ From: Maciej W. Rozycki commit e5f5a5b06e51a36f6ddf31a4a485358263953a3d upstream. Correct a commit 515a6393dbac ("MIPS: kernel: proc: Add MIPS R6 support to /proc/cpuinfo") regression that caused MIPS I systems to show no ISA levels supported in /proc/cpuinfo, e.g.: system type : Digital DECstation 2100/3100 machine : Unknown processor : 0 cpu model : R3000 V2.0 FPU V2.0 BogoMIPS : 10.69 wait instruction : no microsecond timers : no tlb_entries : 64 extra interrupt vector : no hardware watchpoint : no isa : ASEs implemented : shadow register sets : 1 kscratch registers : 0 package : 0 core : 0 VCED exceptions : not available VCEI exceptions : not available and similarly exclude `mips1' from the ISA list for any processors below MIPSr1. This is because the condition to show `mips1' on has been made `cpu_has_mips_r1' rather than newly-introduced `cpu_has_mips_1'. Use the correct condition then.
