David Gibson 74b41e5676 pseries: Allow writes to KVM accelerated TCE table ... Sufficiently recent kernels include a KVM call to accelerate use of PAPR TCE tables (IOMMU), which are used by PAPR virtual IO devices. This involves qemu mapping the TCE table in from a kernel obtained fd, which currently we do with PROT_READ only. This is a hangover from early (never released) versions of this kernel interface which only permitted read-only mappings and required us to destroy and recreate the table when we needed to clear it from qemu. Now, the kernel permits read-write mappings, and we rely on this to clear the table in spapr_vio_quiesce_one(). However, due to insufficient testing, I forgot to update the actual mapping of the table in kvmppc_create_spapr_tce() to add PROT_WRITE to the mmap(). This patch corrects the oversight.
