Update of /cvsroot/linux-vax/kernel-2.5/arch/vax/kernel
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17291/kernel
Modified Files:
syscall.c
Log Message:
- Add config options to switch off abortion of syscalls with wrong
number of arguments and the matching warning for it.
- Update ka4x_defconfig.
- This is only in place to help Kaj-Michael with TA-Linux. It'll go
away after his getty is fixed (which I think causes the error messages
he gets out of his system...).
