  "message": "proc: make switch_to(NULL) a noop\n\nPreviously, it would switch out of any address space and into the\nboot_pgdir.  However, it wouldn\u0027t permanently leave the process\u0027s\naddress space, and boot_pgdir is mapped in all address spaces.  No one\nwas using it in this manner.\n\nAlthough I can think of reasons to do this, no one was doing it, and\nit\u0027s more convenient to have NULL be a noop.  In particular, this is for\nPCI code that may or may not need to switch into a process\u0027s address\nspace.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
