James Hogan 2c0b1df88b metag/usercopy: Fix src fixup in from user rapf loops ... The fixup code to rewind the source pointer in __asm_copy_from_user_{32,64}bit_rapf_loop() always rewound the source by a single unit (4 or 8 bytes), however this is insufficient if the fault didn't occur on the first load in the loop, as the source pointer will have been incremented but nothing will have been stored until all 4 register [pairs] are loaded. Read the LSM_STEP field of TXSTATUS (which is already loaded into a register), a bit like the copy_to_user versions, to determine how many iterations of MGET[DL] have taken place, all of which need rewinding.
