The reason I didn't add it was because \nhash__local_flush_tlb_mm() and hash__flush_tlb_mm() don't have one, yet \nit's also not supported. And I had faith in a developer thinking about \nusing it would see the comment.\nI was actually pretty close to have hash__local_flush_all_mm() call \ndirectly hash__local_flush_tlb_mm(), since the \"all\" stands for \"pwc and \ntlb\" and pwc doesn't exist for hash. But that doesn't do us any good for \nthe time being.\n\nMichael: any preference?\n\nSide note: I'm under the impression that flush_tlb_mm() may be called on \nhash, even though it does nothing. kernel/fork.c, dup_mmap() and \npotentially another (through cscope).\n\n Fred\n\n\n> Otherwise looks good and is also needed for NPU.\n> \n> Reviewed-By: Alistair Popple \n> \n>> +}\n>> +\n>> +static inline void hash__flush_all_mm(struct mm_struct *mm)\n>> +{\n>> +\t/*\n>> +\t * There's no Page Walk Cache for hash, so what is needed is\n>> +\t * the same as flush_tlb_mm(), which doesn't really make sense\n>> +\t * with hash.
