[Xen-devel] [PATCH 1/4] arm: remove incorrect dcache flush at start of day.

flush_xen_dcache flushes by virtual address and at this point boot_ttbr
contains a physical address.

The actual virtual address of the root pagetable is within the region flushed
by the following flush of the _start to _end range.
