Subject: [PATCH 0/4] __asm_copy_to-from_user: Fixes

These are series for the fix reported by Guenter, Geert and Qiu.

One patch to fix overrun memory access, one patch to fix on rv32.
And two more for clean up and typos.

Have tested on qemu rv32, qemu rv64 and beaglev beta board.

Thanks for the report and instructions to reproduce the error on rv32.

Akira
