Re: [Xen-devel] [PATCH 01/28] ARM: export __flush_dcache_area()

The ability to clean a cache line is not only useful for EFI, but will

Export the function to be usable from the whole Xen/ARM code.

There is already a function to clean & invalidate. See clean_and_invalidate_dcache_va_range in include/asm-arm/page.h

So please use this function and leave __flush_dcache_area only exported to EFI.
