This reverts commits:5e46e29e6a("powerpc/64s/hash: convert SLB miss handlers to C")8fed04d0f6("powerpc/64s/hash: remove user SLB data from the paca")655deecf67("powerpc/64s/hash: SLB allocation status bitmaps")2e1626744e("powerpc/64s/hash: provide arch_setup_exec hooks for hash slice setup")89ca4e126a("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. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
