Subject: ia64: switch to generic version of pte allocation
The ia64 implementation pte_alloc_one(), pte_alloc_one_kernel(),
pte_free_kernel() and pte_free() is identical to the generic except of
lack of __GFP_ACCOUNT for the user PTEs allocation.
Switch ia64 to use generic version of these functions.
