[PATCH v1 02/06]: Avoid using the same object file in the kernel and modules

[Ruslan Nikolaev]

Avoid using the same object file in the kernel and modules

The patch is by Hassan Nadeem and Ruslan Nikolaev. This extends
the prior PIE kernel patch (by Thomas Garnier) to also support
position-independent modules that can be placed anywhere in the
48/64-bit address space (for better KASLR).
