Andreas Kling 197e73ee31 Kernel+LibELF: Enable SMAP protection during non-syscall exec() ...

When loading a new executable, we now map the ELF image in kernel-only
memory and parse it there. Then we use copy_to_user() when initializing
writable regions with data from the executable.

Note that the exec() syscall still disables SMAP protection and will
require additional work. This patch only affects kernel-originated
process spawns.
