Revert to the correct # address range. # # Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page # state in process X" errors when reclaiming from a KVM guest due to KVM # removing the wrong pages from its own mappings. # # Reported-by: leozinho29_eu@hotmail.com # Reported-by: Mike Galbraith <efault@gmx.de> # Reported-and-tested-by: Adam Borowski <kilobyte@angband.pl> # Reviewed-by: Jérôme Glisse <jglisse@redhat.com> # Reviewed-by: Pankaj gupta <pagupta@redhat.com> # Cc: Christian König <christian.koenig@amd.com> # Cc: Jan Kara <jack@suse.cz> # Cc: Matthew Wilcox <mawilcox@microsoft.com> # Cc: Ross Zwisler <zwisler@kernel.org> # Cc: Dan Williams <dan.j.williams@intel.com> # Cc: Paolo Bonzini <pbonzini@redhat.com> # Cc: Radim Krčmář <rkrcmar@redhat.com> # Cc: Michal Hocko <mhocko@kernel.org> # Cc: Felix Kuehling <felix.kuehling@amd.com> # Cc: Ralph Campbell <rcampbell@nvidia.com> # Cc: John Hubbard <jhubbard@nvidia.com> # Cc: Andrew Morton <akpm@linux-foundation.org> # Fixes: ac46d4f3c432 ("mm/mmu_notifier: use structure for invalidate_range_start/end calls v2") # Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/or1k-linux-5.4.0-20170218/or1k-linux/bin/or1k-linux-gcc --version # < /opt/cross/kisskb/or1k-linux-5.4.0-20170218/or1k-linux/bin/or1k-linux-ld --version # < git log --format=%s --max-count=1 ba422731316dde1e22dcc84b83c7349dc0ce1c3c # < make -s -j 120 ARCH=openrisc O=/kisskb/build/linus_or1ksim_defconfig_or32 CROSS_COMPILE=/opt/cross/kisskb/or1k-linux-5.4.0-20170218/or1k-linux/bin/or1k-linux- or1ksim_defconfig # make -s -j 120 ARCH=openrisc O=/kisskb/build/linus_or1ksim_defconfig_or32 CROSS_COMPILE=/opt/cross/kisskb/or1k-linux-5.4.0-20170218/or1k-linux/bin/or1k-linux- Completed OK # rm -rf /kisskb/build/linus_or1ksim_defconfig_or32 # Build took: 0:00:14.340166
