|

* of the normal 2 arguments. The 4th argument contains the "Translation-
|
||||
* Exception Identification for DAT Exceptions" from the hardware (aka
|
||||
* "int_parm_long"), which does in fact contain the is_write value.
|
||||
* The rt signal handler, as far as I can tell, does not give this value
|
||||
* at all. Not that we could get to it from here even if it were.
|
||||
* So fall back to parsing instructions. Treat read-modify-write ones as
|
||||
* writes, which is not fully correct, but for tracking self-modifying code
|
||||
* this is better than treating them as reads. Checking si_addr page flags
|
||||
* might be a viable improvement, albeit a racy one.
