From f384796c40dc55b3dba25e0ee9c1afd98c6d24d1 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 26 Mar 2018 15:34:48 +0530 Subject: powerpc/mm: Add support for handling > 512TB address in SLB miss For addresses above 512TB we allocate additional mmu contexts. To make it all easy, addresses above 512TB are handled with IR/DR=1 and with stack frame setup. The mmu_context_t is also updated to track the new extended_ids. To support upto 4PB we need a total 8 contexts.
