When CONFIG_PDX_COMPRESSION=n, pdx_init_mask(), pdx_region_mask() and

sense to keep the two loops iterating over all the memory banks.
I saw this was already committed. But I have a question. Wouldn't the
compiler be able to optimize and remove the loops? Asking because we are
trying to limit the number of #ifdef in the code hence why we have stubs.
Before submitting a patch I did disassembled init_pdx() with and without my
patch and in the latter case the compiler did not optimize out the loops.
One more question. Was this in debug or non-debug build?
