Based on work from Richard and Thomas. v4 -> v5: - Don't realy on TLB_INVALID_MASK -- Check against tlb_fill_exc and return the exception right away - Handle !CONFIG_USER_ONLY -- Check against haddr -- Properly store vaddr to env->__excp_addr and return PGM_ADDRESSING - Exclude tlb_fill_tec/tlb_fill_exc for CONFIG_USER_ONLY - While at it, tackle r1/r2 indication as well
The ifdeffery in patch #1 is a bit ugly but IMHO but still tolerable. KVM unit tests continue working as expected.
