A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
