			. added safecopies.c: these are library functions to maintain grant tables in own address space . sys_safecopy.c: interfaces to kernel calls to perform safe copy functions in from or to foreign process . changes in i/o fields (type merged with request) reflected in library functions (sys_out.c, sys_vinb.c, sys_vinl.c, sys_vinw.c, sys_voutb.c, sys_voutl.c, sys_voutw.c) . type merged with request in sys_sdevio, also now accepts offset which is used when a grant is specified (the _DIO_SAFE subtype) . system printf() function changed to send DIAGNOSTICS_S messages, which specify a grant id instead of a direct address for the buffer to be printed; tty and log can then safecopy the buffer
