rewrite using qr{} instead of map

[PATCH v3 00/41] arch: barrier cleanup + barriers for virt
Changes since v2:
- extended checkpatch tests for barriers, and added patches
teaching it to warn about incorrect usage of barriers
(__smp_xxx barriers are for use by asm-generic code only),
should help prevent misuse by arch code
to address comments by Russell King
- patched more instances of xen to use virt_ barriers
as suggested by Stefano Stabellini
- implemented a 2 byte xchg on sh
