Patch that allows binfmt_misc to be compiled and used on embedded
devices (such as Android) where the kernel itself can't trivially
be changed.

A brief explanation of the actual problem can be found below:

<[machine]> so basically the mount point for binfmt_misc doesn't get made in the module on load, oh no, it gets made in the "main" kernel code, but only if the module is
            enabled when that code is compiled.. so if you compile /just/ the module later, no mount point... and well, if you use proc_mkdir to fix that, you end up
            with 2 /proc/sys's (the real one plus a shadow).. eventually i sussed this and then found sysctl stuff which allows you to define a table which becomes
            /proc/sys (and add to it)
<[machine]> there is no way a normal user is going to bother with that

This patch is based on kernel_2.6.35_nvidia_base as used by VegaComb.
