From a640d6762a7d404644201ebf6d2a078e8dc84f97 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Fri, 2 Feb 2024 18:21:47 +0000 Subject: MIPS: mipsregs: Set proper ISA level for virt extensions c994a3ec7ecc ("MIPS: set mips32r5 for virt extensions") setted some instructions in virt extensions to ISA level mips32r5. However TLB related vz instructions was leftover, also this shouldn't be done to a R5 or R6 kernel buid. Reorg macros to set ISA level as needed when _ASM_SET_VIRT is called.
