Lionel Landwerlin 2841af6238 intel: gen-decoder: don't decode fields beyond a dword length 
For example, a PIPE_CONTROL with DWordLength = 2 should look like
this :

0xffffe374:  0x7a000002:  PIPE_CONTROL
0xffffe374:  0x7a000002 : Dword 0
    DWord Length: 2
0xffffe378:  0x00800000 : Dword 1
    Depth Cache Flush Enable: false
    Stall At Pixel Scoreboard: false
    State Cache Invalidation Enable: false
    Constant Cache Invalidation Enable: false
    VF Cache Invalidation Enable: false
    DC Flush Enable: false
    Pipe Control Flush Enable: false
    Notify Enable: false
    Indirect State Pointers Disable: false
    Texture Cache Invalidation Enable: false
    Instruction Cache Invalidate Enable: false
    Render Target Cache Flush Enable: false
    Depth Stall Enable: false
    Post Sync Operation: 0 (No Write)
    Generic Media State Clear: false
    TLB Invalidate: false
    Global Snapshot Count Reset: false
    Command Streamer Stall Enable: false
    Store Data Index: 0
    LRI Post Sync Operation: 1 (MMIO Write Immediate Data)
    Destination Address Type: 0 (PPGTT)
    Flush LLC: false
0xffffe37c:  0x00000000 : Dword 2
    Address: 0x00000000
0xffffe384:  0x05000000:  MI_BATCH_BUFFER_END

Prior to this change, fields beyond the length of the command would be
decoded (notice the MI_BATCH_BUFFER_END decoded as part of the
previous PIPE_CONTROL) :

0xffffe374:  0x7a000002:  PIPE_CONTROL
0xffffe374:  0x7a000002 : Dword 0
    DWord Length: 2
0xffffe378:  0x00800000 : Dword 1
    Depth Cache Flush Enable: false
    Stall At Pixel Scoreboard: false
    State Cache Invalidation Enable: false
    Constant Cache Invalidation Enable: false
    VF Cache Invalidation Enable: false
    DC Flush Enable: false
    Pipe Control Flush Enable: false
    Notify Enable: false
    Indirect State Pointers Disable: false
    Texture Cache Invalidation Enable: false
    Instruction Cache Invalidate Enable: false
    Render Target Cache Flush Enable: false
    Depth Stall Enable: false
    Post Sync Operation: 0 (No Write)
    Generic Media State Clear: false
    TLB Invalidate: false
    Global Snapshot Count Reset: false
    Command Streamer Stall Enable: false
    Store Data Index: 0
    LRI Post Sync Operation: 1 (MMIO Write Immediate Data)
    Destination Address Type: 0 (PPGTT)
    Flush LLC: false
0xffffe37c:  0x00000000 : Dword 2
    Address: 0x00000000
0xffffe380:  0x00000000 : Dword 3
0xffffe384:  0x05000000 : Dword 4
    Immediate Data: 83886080
0xffffe384:  0x05000000:  MI_BATCH_BUFFER_END
