[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v9 2/8] xen/arm: rename *_xen_dcache_* operations to *_dcache_*
Given that we are in Xen, it is obvious that these are Xen flushes.
Also the correspondent x86 functions are going to be named without
_xen_, so remove it here for consistency.
