Is now very similar to normal importer, and may be deleted in the future, but at the moment, this should be merged, since it is the importer used in the sobres-2013 paper. This changes the MySQL Schema. instr1_absolute was introduced. Change-Id: I1bc2919bd14c335beca6d586b7cc0f80767ad7d5

/** \class DCiAOKernelImporter
|
|
*
|
|
* Strategy for importing traces into the MySQL Database, that cover
|
|
* only kernel space data address. A single trace is only added to the
|
|
* database, if it has the following form:
|
|
*
|
|
* - The memory access is after the kernel has passed the
|
|
* getEnterKernelAddress(), before it passes the
|
|
* getLeaveKernelAddress() again. Short: if the programm is in
|
|
* kernel space.
|
|
* - Only memory addresses that are located in the os::data::dynamic
|
|
* namespace
|
|
* - Only memory accesses to addresses that were not written in the
|
|
* current kernel space phase.
