-The final category of APIs is for I/O to deliberately aliased address
-ranges inside the kernel.  Such aliases are set up by use of the
-vmap/vmalloc API.  Since kernel I/O goes via physical pages, the I/O
-subsystem assumes that the user mapping and kernel offset mapping are
-the only aliases.  This isn't true for vmap aliases, so anything in
-the kernel trying to do I/O to vmap areas must manually manage
-coherency.  It must do this by flushing the vmap range before doing
-I/O and invalidating it after the I/O returns.

-  void flush_kernel_vmap_range(void *vaddr, int size)
-       flushes the kernel cache for a given virtual address range in
-       the vmap area.  This is to make sure that any data the kernel
-       modified in the vmap range is made visible to the physical
-       page.  The design is to make this area safe to perform I/O on.
-       Note that this API does *not* also flush the offset map alias

-
-  void invalidate_kernel_vmap_range(void *vaddr, int size) invalidates
-       the cache for a given virtual address range in the vmap area
-       which prevents the processor from making the cache stale by
-       speculatively reading data while the I/O was occurring to the
-       physical pages.  This is only necessary for data reads into the
-       vmap area.
