[Qemu-devel] [PULL 8/8] target/ppc: fix tlbsync to check privilege level depending on GTSE

[David Gibson]

From: Cédric Le Goater <address@hidden>

tlbsync also needs to check the Guest Translation Shootdown Enable
(GTSE) bit in the Logical Partition Control Register (LPCR) to
determine at which privilege level it is running.

See commit c6fd28fd573d ("target/ppc: Update tlbie to check privilege
level based on GTSE")
