#     powerpc: Select ARCH_WANTS_MODULES_DATA_IN_VMALLOC on book3s/32 and 8xx
#     
#     book3s/32 and 8xx have a separate area for allocating modules,
#     defined by MODULES_VADDR / MODULES_END.
#     
#     On book3s/32, it is not possible to protect against execution
#     on a page basis. A full 256M segment is either Exec or NoExec.
#     The module area is in an Exec segment while vmalloc area is
#     in a NoExec segment.
#     
#     In order to protect module data against execution, select
#     ARCH_WANTS_MODULES_DATA_IN_VMALLOC.
#     
#     For the 8xx (and possibly other 32 bits platform in the future),
#     there is no such constraint on Exec/NoExec protection, however
#     there is a critical distance between kernel functions and callers
#     that needs to remain below 32Mbytes in order to avoid costly
#     trampolines. By allocating data outside of module area, we
#     increase the chance for module text to remain within acceptable
#     distance from kernel core text.
#     
#     So select ARCH_WANTS_MODULES_DATA_IN_VMALLOC for 8xx as well.
