By design the IA64 instruction cache does not detect self modifying code, so an instruction can be changed in memory but the old instruction can still be in cache. ia64_fc is used to flush the changed cacheline to ensure that you execute the modified instruction. >and what is the different of >system_call_table among ia64,x86_64t and i386? You will have to be more specific about your question, what are you trying to do with the syscall table? Since you are also asking about ia64_fc I guess that you are trying to patch the syscall table, and the standard answer to that is "DO NOT PATCH THE SYSCALL TABLE!". It is not supported and will not be supported. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
