[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v4 1/7] xen/arm: Import ID registers definitions from Linux
Import some ID registers definitions from Linux sysreg header to have
required shift definitions for all ID registers fields.
Those are required to reuse the cpufeature sanitization system from
Linux kernel.
