In memory KASLR, __PHYSICAL_MASK_SHIFT is taken to calculate the
initial size of the direct mapping region. This is right in the
old code where __PHYSICAL_MASK_SHIFT was equal to MAX_PHYSMEM_BITS,
46bit, and only 4-level mode was supported.

In memory KASLR, __PHYSICAL_MASK_SHIFT is taken to calculate the
initial size of the direct mapping region. This is right in the
old code where __PHYSICAL_MASK_SHIFT was equal to MAX_PHYSMEM_BITS,
46bit, and only 4-level mode was supported.
