Modified files:
sys/vm vm_mmap.c
Log:
Allow non-page aligned file offset mmap's, providing that the system is
allowed to choose the address, or that the MAP_FIXED address has the same
remainder when modulo PAGE_SIZE as the file offset. Apparently this is
posix1003.1b specified behavior. SVR4 and the other *BSD's allow it too.
It costs us nothing to support and means we don't get EINVAL on some mmap
code that works perfectly elsewhere.
