_PROTOTYPE( int do_procstat, (void) );
Disabled building rescue driver (no longer needed). Moved allocmem from library to the memory driver. Always put output from within TTY directly on the console. Removed second include of driver.h from tty.c. Made tty_inrepcode bigger. First step to move PM and FS calls that are not regular (API) system calls out of callnr.h (renumbered them, and removed them from the table.c files). Imported the Minix-vmd uname implementation. This provides a more stable ABI than the current implementation. Added a bit of security checking. Unfortunately not nearly enough to get a secure system. Fixed a bug related to the sizes of the programs in the image (in PM patch_mem_chunks).

_PROTOTYPE( int do_svrctl, (void) );
Various updates. * Removed some variants of the SYS_GETINFO calls from the kernel; replaced them with new PM and utils libary functionality. Fixed bugs in utils library that used old get_kenv() variant. * Implemented a buffer in the kernel to gather random data. Memory driver periodically checks this for /dev/random. A better random algorithm can now be implemented in the driver. Removed SYS_RANDOM; the SYS_GETINFO call is used instead. * Remove SYS_KMALLOC from the kernel. Memory allocation can now be done at the process manager with new 'other' library functions.

_PROTOTYPE( int do_getsetpriority, (void) );
endpoint-aware conversion of servers. 'who', indicating caller number in pm and fs and some other servers, has been removed in favour of 'who_e' (endpoint) and 'who_p' (proc nr.). In both PM and FS, isokendpt() convert endpoints to process slot numbers, returning OK if it was a valid and consistent endpoint number. okendpt() does the same but panic()s if it doesn't succeed. (In PM, this is pm_isok..) pm and fs keep their own records of process endpoints in their proc tables, which are needed to make kernel calls about those processes. message field names have changed. fs drivers are endpoints. fs now doesn't try to get out of driver deadlock, as the protocol isn't supposed to let that happen any more. (A warning is printed if ELOCKED is detected though.) fproc[].fp_task (indicating which driver the process is suspended on) became an int. PM and FS now get endpoint numbers of initial boot processes from the kernel. These happen to be the same as the old proc numbers, to let user processes reach them with the old numbers, but FS and PM don't know that. All new processes after INIT, even after the generation number wraps around, get endpoint numbers with generation 1 and higher, so the first instances of the boot processes are the only processes ever to have endpoint numbers in the old proc number range. More return code checks of sys_* functions have been added. IS has become endpoint-aware. Ditched the 'text' and 'data' fields in the kernel dump (which show locations, not sizes, so aren't terribly useful) in favour of the endpoint number. Proc number is still visible. Some other dumps (e.g. dmap, rs) show endpoint numbers now too which got the formatting changed. PM reading segments using rw_seg() has changed - it uses other fields in the message now instead of encoding the segment and process number and fd in the fd field. For that it uses _read_pm() and _write_pm() which to _taskcall()s directly in pm/misc.c. PM now sys_exit()s itself on panic(), instead of sys_abort(). RS also talks in endpoints instead of process numbers.
