powerpc/mm: Ensure change_page_attr() doesn't invalidate pinned TLBs __change_page_attr() uses flush_tlb_page(). flush_tlb_page() uses tlbie instruction, which also invalidates pinned TLBs, which is not what we expect. This patch modifies the implementation to use flush_tlb_kernel_range() instead. This will make use of tlbia which will preserve pinned TLBs.
