[PATCH] x86: comment in x86-opcode-map.txt on CALLW discrepancy between Intel and AMD

2014-04-18 Thread Denys Vlasenko
In 64-bit mode, AMD and Intel CPUs treat 0x66 prefix before branch insns differently. For near branches, it affects decode too since immediate offset's width is different. Signed-off-by: Denys Vlasenko CC: Masami Hiramatsu CC: Oleg Nesterov --- arch/x86/lib/x86-opcode-map.txt | 9 + 1
