Heads Up: This patch cannot be submitted to Linus's tree, as the affected assembler functions have already been converted to C.
When calling flush_(inval_)dcache_range with a size >4GB, we were masking off the upper 32 bits, so we would incorrectly flush a range smaller than intended.
This patch replaces the 32 bit shifts with 64 bit ones, so that the full size is accounted for.

This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.
