[XTENSA] Allow debugger to modify the WINDOWBASE register.
For the 'return' command, GDB needs to adjust WINDOWBASE. In case WB is different from 0, we need to rotate the window register file and update WINDOWSTART and WMASK. This patch also removes some ret|= statements for __get_user/__put_user as the address range was alrady checked a couple of lines earlier. Signed-off-by: Chris Zankel <chris@zankel.net>
