andrew added a reviewer: ARM.

I have some feeling that all armv7 TLB operations are inlined already. And cache operations too. At least, it was a goal. Only cpu_setup() method is used from struct cpu_functions armv7 table. Nevertheless, I may be wrong.

All these functions are disconnected from current armv6 kernel. Only remaining user is elf_trampoline, and i hope that we can remove all this stuff in near future.
