H A Dcachetlb.rst376 vmap/vmalloc API. Since kernel I/O goes via physical pages, the I/O
378 the only aliases. This isn't true for vmap aliases, so anything in
379 the kernel trying to do I/O to vmap areas must manually manage
380 coherency. It must do this by flushing the vmap range before doing
386 the vmap area. This is to make sure that any data the kernel
387 modified in the vmap range is made visible to the physical
394 the cache for a given virtual address range in the vmap area
