Helge Deller 06bff6b9d7 parisc: Simplify and speed up get_user() and put_user() ... This patch simplifies the code for get_user() and put_user() a lot. Instead of accessing kernel memory (%sr0) and userspace memory (%sr3) hard-coded in the assembler instruction, we now preload %sr2 with either %sr0 (for accessing KERNEL_DS) or with sr3 (to access USER_DS) and use %sr2 in the load directly. The generated code avoids a branch and speeds up execution by generating less assembler instructions.
