/*
* POWER Data Stream Control Register (DSCR) explicit test
*
* This test modifies the DSCR value using mtspr instruction and
* verifies the change with mfspr instruction. It uses both the
* privilege state SPR and the problem state SPR for this purpose.
*
* When using the privilege state SPR, the instructions such as
* mfspr or mtspr are priviledged and the kernel emulates them
* for us. Instructions using problem state SPR can be exuecuted
* directly without any emulation if the HW supports them. Else
* they also get emulated by the kernel.
