Revert "convert SLB miss handlers to C" and subsequent commits
This reverts commits:
5e46e29e6a97 ("powerpc/64s/hash: convert SLB miss handlers to C")
8fed04d0f6ae ("powerpc/64s/hash: remove user SLB data from the paca")
655deecf67b2 ("powerpc/64s/hash: SLB allocation status bitmaps")
2e1626744e8d ("powerpc/64s/hash: provide arch_setup_exec hooks for hash slice setup")
89ca4e126a3f ("powerpc/64s/hash: Add a SLB preload cache")
This series had a few bugs, and the fixes are not all trivial. So
revert most of it for now.
