Merge branch 'next-fixes-for-5.2-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity subsystem fixes from Mimi Zohar: "Four bug fixes, none 5.2-specific, all marked for stable. The first two are related to the architecture specific IMA policy support. The other two patches, one is related to EVM signatures, based on additional hash algorithms, and the other is related to displaying the IMA policy" * 'next-fixes-for-5.2-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: ima: show rules with IMA_INMASK correctly evm: check hash algorithm passed to init_desc() ima: fix wrong signed policy requirement when not appraising x86/ima: Check EFI_RUNTIME_SERVICES before using
