[PATCH] exec: allow > 2GB executables to run on 64-bit systems

[Dave Anderson]

When a executable that is greater than 2GB in size is attempted on a 64-bit
system on a file system that calls, or uses generic_file_open() as its
open handler, it fails with an EOVERFLOW erro.  This patch adds a call
to force_o_largefile() call in open_exec(), as done in sys_open() and
sys_openat().
