59  align_mask = Align a virtual address to avoid aliasing in the I$ on AMD F15h.
60  addr = addr + align_mask & ~align_mask
61  Return addr | To avoid aliasing in the I$ on AMD F15h, the bits defined by the* va_align.bits, [12:upper_bit), are set to a random value instead of* zeroing them. This random value is computed once per boot. This form* of ASLR is known as "per-boot ASLR".
