Max Filippov 61a6b91283 xtensa: don't use a12 in __xtensa_copy_user in call0 ABI ... a12 is callee-saved register in xtensa call0 ABI, so a function must not change it. The main unaligned copy loop of __xtensa_copy_user uses all low-numbered registers, so a register must be spilled to avoid using a12 as a loop counter.
