Is copyout() MPSAFE on non-i386 archs? Message-ID: <200202160500.g1G50j145638@apollo.backplane.com>

Poul indicated today that the microtime() call that gettimeofday() uses
is MPSAFE. copyout() on I386 is MPSAFE, and from my perusal of the
other archs it appears to be MPSAFE for alpha, ia64, and sparc64
as well.
This would seem to indicate that Giant can be removed from the
gettimeofday() system call. I would like those familiar with the
other archs to verify that copyout() is MPSAFE on them. I am testing
Giant removal for this syscall on i386 now.
