From: James Morse <james.morse@arm.com> maillist inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8T2RT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git/log/?h=mpam/... --------------------------- Pseudo lock isn't supported on arm64. Add empty definitions of the functions arm64 doesn't implement. Because the Kconfig option is not selected, none of these will be called.
