f6f38dd61e Changed the test that determines whether or not source and destination 
memory regions are "potentially overlapping" to a test that determines
that the regions are actually overlapping.  Because the code for the
overlapping case is seven instructions longer, this signifcantly
improves performance in the average case.

c9ec05f4b2 Treat reboot() like a normal system call. From PR 2458. 1996-11-11 13:41:08 +00:00

9d7f517756 Added new macros: 
SYSTRAP(x):             Expands to the code used to call syscall x.
				This is used to simplify other macros.

        SYSCALL_NOERROR(x):     Like SYSCALL except that "x" is a syscall
				that can never fail.

        RSYSCALL_NOERROR(x):    Like RSYSCALL except that "x" is a syscall
				that can never fail.

e7d917e6eb Remove extra "u" constraint that caused gcc 2.6.3 not to compile this file. 
Note that gcc 2.4.5, the compiler we are currently using, still compiles it
correctly after this change.
