Miodrag Dinic d4d732cfa4 FROMLIST: MIPS: Add noexec=on|off kernel parameter 
Add a new kernel parameter to override the default behavior related to
the decision whether to indicate stack as non-executable or executable
(regardless of PT_GNU_STACK entry or CPU RIXI support) in function
mips_elf_read_implies_exec().

Allowed values:

noexec=on:	force indicating non-exec stack & heap
noexec=off:	force indicating executable stack & heap

If this parameter is omitted, kernel behavior remains the same as it
was before this patch is applied.

This functionality is convenient during debugging and is especially
useful for Android development where indication of non-executable
stack is required.

NOTE: Using noexec=on on a system without CPU XI support is not
recommended since there is no actual HW support that provide
non-executable stack and heap. Use only for debugging purposes and
not in a production environment.
