[LV-k25-commit] kernel-2.5/arch/vax/kernel syscall.c,1.10,1.11

[Jan-Benedict G. <jb...@us...>]

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...).
