powerpc/603: Copy kernel PGD entries into all PGDIRs and preallocate execmem page tables
For the same reason as 8xx, copy kernel PGD entries into all
PGDIRs in pgd_alloc() and preallocate execmem page tables before
creating new PGDs so that all PGD entries related to execmem are
copied by pgd_alloc().
This will help reduce the fast-path in TLBmiss handlers.
