- clean up kernel section of minix/com.h somewhat - remove ALLOCMEM and VM_ALLOCMEM calls - remove non-safecopy and minix-vmd support from Inet - remove SYS_VIRVCOPY and SYS_PHYSVCOPY calls - remove obsolete segment encoding in SYS_SAFECOPY* - remove DEVCTL call, svrctl(FSDEVUNMAP), map_driverX - remove declarations of unimplemented svrctl requests - remove everything related to swapping to disk - remove floppysetup.sh - remove traces of rescue device - update DESCRIBE.sh with new devices - some other small changes
