New Revision: 205574
URL: http://svn.freebsd.org/changeset/base/205574
Log:
The nargvstr and nenvstr properties of arginfo are ints, not longs,
so should be copied to userspace with suword32() instead of suword().
This alleviates problems on 64-bit big-endian architectures, and is a
no-op on all 32-bit architectures.
Tested on: amd64, sparc64, powerpc64
