[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 02/21] xen/arm: Constify address pointer for cache helpers
The memory pointed by this pointer is not modified in clean_xen_dcache_va_range and clean_and_invalidate_xen_dcache_va_range. Constify it. This will allow us to use theses helpers later in code which use const.
