[PATCH v1 0/2] x86: Secure Memory Encryption (SME) fixes 2017-07-26

[PATCH v1 2/2] acpi, x86: Remove encryption mask from ACPI page protection type

The function arch_apei_get_mem_attributes() is used to set the page protection type for ACPI physical addresses. When SME is active, the associated protection type needs to not have the encryption mask set since the ACPI tables live in un-encrypted memory. Modify the arch_apei_get_mem_attributes()
