Subject: [PATCH 1/3] KVM: PPC: Avoid referencing userspace memory region in
memslot updates
For PPC HV, get the number of pages directly from the new memslot instead
of computing the same from the userspace memory region, and explicitly
check for !DELETE instead of inferring the same when toggling mmio_update.
The motivation for these changes is to avoid referencing the @mem param
so that it can be dropped in a future commit.
No functional change intended.

Subject: [PATCH 2/3] powerpc: kvmppc_unmap_free_pmd() pte_offset_kernel()
kvmppc_unmap_free_pmd() use pte_offset_kernel(), like everywhere else
in book3s_64_mmu_radix.c: instead of pte_offset_map(), which will come
to need a pte_unmap() to balance it.
But note that this is a more complex case than most: see those -EAGAINs
in kvmppc_create_pte(), which is coping with kvmppc races beween page
table and huge entry, of the kind which we are expecting to address
in pte_offset_map() - this might want to be revisited in future.
