[PATCH 0/3] ppc: Check for bad Radix configs |

On PowerPC64 using Radix MMU, when partition or process table is not
properly aligned, according to their size, an exception must be raised
(DSI/ISI/HDSI/HISI) and the "Bad Radix Config" bit must be set in the
appropriate register.
Hardware and KVM already do this, but TCG was missing this part.
This patch series also improves the code that validates each Radix Tree
level, by checking the number of levels and the size of each one.
Finally, when DEBUG_MMU is defined, PDE/PTE base address alignment is
also checked and reported, to make it easier to detect invalid
configurations.

ppc: Check partition and process table alignment
target/ppc: Improve Radix xlate level validation
target/ppc: Check page dir/table base alignment
