From 235266b8e11c9db12497bdfc6d5e9100f3434c24 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Wed, 31 Jan 2018 16:16:59 -0800 Subject: selftests/vm: move 128TB mmap boundary test to generic directory Architectures like PPC64 support mmap hint address based large address space selection. This test can be run on those architectures too. Move the test from the x86 selftests to selftest/vm so that other architectures can use it too. We also add a few new test scenarios in this patch. We do test a few boundary conditions before we do a high address mmap. PPC64 uses the address limit to validate the address in the fault path. We had bugs in this area w.r.t SLB fault handling before we updated the addess limit. We also touch the allocated space to make sure we don't have any bugs in the fault handling path.
