New Revision: 345355
URL: https://svnweb.freebsd.org/changeset/base/345355
Log:
Ensure that we use a 64-bit value for the last mmap() argument.
When using __syscall(2), the offset argument is passed on the stack on
amd64. Previously only 32 bits were written, so the upper 32 bits were
garbage and could cause the test to fail.
