Don't do this.

Don't use that either.
Add an entry to the mapping tables ("MAPPING" in 2.2, or the io_desc
in 2.3). The routines that scan these tables will then sort out the
page or section mappings as appropriate to achieve your required mapping
at the least cost to the TLB.
PS, this is a kernel question. Please post such questions to the
linux-arm-kernel mailing list, details are on the web site.
