    CVSROOT: /cvs
    Module name: src
    Changes by: artcvs.openbsd.org 2002/11/06 21:39:15

    Modified files:
            sys/arch/sparc/sparc: machdep.c

    Log message:
    Don't uvm_useracc the user sigcontext in sys_sigreturn and then access
    the user addresses directly from the kernel. copyin is faster and can
    correctly deal properly with mappings that uvm_useracc thinks are
    correct but will fault anyway (to figure out how to generate such
    mappings is left as en excercise for the reader).
