[Qemu-devel] [PULL 01/17] target/ppc: return a nil HPT base address on sPAPR machines

[David Gibson]

From: Cédric Le Goater <c...@kaod.org>

commit e57ca75ce3b2 ("target/ppc: Manage external HPT via virtual
hypervisor") exported a set of methods to manipulate the HPT from the
core hash MMU. But SPR_SDR1 is still used under some circumstances to
get the base address of the HPT, which is incorrect for the sPAPR
machines.

Only the logging should be impacted.
