The new auditing standard for the subsystem will be to only use __aligned_64 in uapi headers to try and prevent 32/64 compat bugs from existing in the future. Changing all existing usage will help ensure new developers copy the right idea. The before/after of this patch was tested using pahole on 32 and 64 bit compiles to confirm it has no change in the structure layout, so this patch is a NOP.
