Brian Feldman 25ead03462 Solve the problem where it is possible to get the kernel stuck in 
a loop down in pmap_init_pt().  A subtraction causes the number of
pages to become negative, that was assigned to an unsigned variable,
and there is a lot of iteration.  The bug is due to the ELF image
activator not properly checking for its files being the correct size
as specified by the ELF header.

The solution is to check that the header doesn't ask for part of a
file when that part of the file doesn't exist.  Make sure to set
VEXEC at the proper times to make the executables immutable (remove
race conditions).  Also, the ELF format specifiies header entries
that allow embedding of other executables (hence how ld-elf.so.1
gets loaded, but not the same as loading shared libraries), so those
executables need to be set VEXEC, too, so they're immutable.
