Export the init_mm symbol to GPL modules so that MIPS KVM can use
pgd_alloc() to create GVA page directory tables for trap & emulate mode,
which runs guest code in user mode. On MIPS pgd_alloc() is implemented
inline and refers to init_mm in order to copy kernel address space
mappings into the new page directory.
