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.
