Revision 8acc0993e3f9a04a407ff1507dd329455f340121 authored by Kai Huang on 15 January 2019, 04:28:40 UTC, committed by Paolo Bonzini on 20 February 2019, 21:48:25 UTC
AMD's SME/SEV is no longer the only case which reduces supported physical address bits, since Intel introduced Multi-key Total Memory Encryption (MKTME), which repurposes high bits of physical address as keyID, thus effectively shrinks supported physical address bits. To cover both cases (and potential similar future features), kernel MM introduced generic dynamaic physical address mask instead of hard-coded __PHYSICAL_MASK in 'commit 94d49eb30e854 ("x86/mm: Decouple dynamic __PHYSICAL_MASK from AMD SME")'. KVM should use that too. Change PT64_BASE_ADDR_MASK to use kernel dynamic physical address mask when it is enabled, instead of sme_clr. PT64_DIR_BASE_ADDR_MASK is also deleted since it is not used at all. Signed-off-by: Kai Huang <kai.huang@linux.intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
