  powerpc/64s: fix scv entry fallback flush vs interrupt (2021-01-20 15:58:19 +1100)

- ------------------------------------------------------------------
powerpc fixes for 5.11 #5

Fix a bad interaction between the scv handling and the fallback L1D flush, which
could lead to user register corruption. Only affects people using scv (~no one)
on machines with old firmware that are missing the L1D flush.

Two small selftest fixes.

Thanks to Eirik Fuller, Libor Pechacek, Nicholas Piggin, Sandipan Das, Tulio
Magno Quites Machado Filho.
