ce79dac861 x86, opcode: ANDN and Group 17 in x86-opcode-map.txt
The Intel documentation at

http://software.intel.com/file/36945

shows the ANDN opcode and Group 17 with encoding f2 and f3 encoding
respectively.  The current version of x86-opcode-map.txt shows them
with f3 and f4.  Unless someone can point to documentation which shows
the currently used encoding the following patch be applied.

8d973b624e x86/kprobes: Fix typo transferred from Intel manual
The arch/x86/lib/x86-opcode-map.txt file [used by the
kprobes instruction decoder] contains the line:

  af: SCAS/W/D/Q rAX,Xv

This is what the Intel manuals show, but it's not correct.
The 'X' stands for:

  Memory addressed by the DS:rSI register pair (for example, MOVS, CMPS, OUTS, or LODS).

On the other hand 'Y' means (also see the ae byte entry for
SCASB):

  Memory addressed by the ES:rDI register pair (for example, MOVS, CMPS, INS, STOS, or SCAS).

a9c373d033 x86: Update instruction decoder to support new AVX formats
Since new Intel software developers manual introduces
new format for AVX instruction set (including AVX2),
it is important to update x86-opcode-map.txt to fit
those changes.

d1baf5a5a6 x86: Add AMD prefetch and 3DNow! opcodes to opcode map
Add AMD prefetch and 3DNow! opcode including FEMMS. Since 3DNow!
uses the last immediate byte as an opcode extension byte, x86
insn just treats the extenstion byte as an immediate byte
instead of a part of opcode (insn_get_opcode() decodes first
"0x0f 0x0f" bytes.)

Users who are interested in analyzing 3DNow! opcode still can
decode it by analyzing the immediate byte.

eb13296cfa x86: Instruction decoder API
Add x86 instruction decoder to arch-specific libraries. This decoder
can decode x86 instructions used in kernel into prefix, opcode, modrm,
sib, displacement and immediates. This can also show the length of
instructions.

This version introduces instruction attributes for decoding
instructions.
The instruction attribute tables are generated from the opcode map file
(x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk).

Currently, the opcode maps are based on opcode maps in Intel(R) 64 and
IA-32 Architectures Software Developers Manual Vol.2: Appendix.A,
and consist of below two types of opcode tables.

1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are
written as below;

 Table: table-name
 Referrer: escaped-name
 opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...]
  (or)
 opcode: escape # escaped-name
 EndTable

Group opcodes, which has 8 elements, are written as below;

 GrpTable: GrpXXX
 reg:  mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...]
 EndTable

These opcode maps include a few SSE and FP opcodes (for setup), because
those opcodes are used in the kernel.
