This patchset simplifies sme_populate_pgd(), sme_populate_pgd_large() and
sme_pgtable_calc() functions.
As a side effect, the patchset makes encryption code ready to boot-time
switching between paging modes.
The patchset is build on top of Tom's "x86: SME: BSP/SME microcode update
fix" patchset.
It was only build-tested. Tom, could you please get it tested properly?
