Replacing a 2K page table with a 4K page table while a VMA is active for the affected memory region is fundamentally broken. Rip out the page table reallocation code and replace it with a simple system control 'vm.allocate_pgste'. If the system control is set the page tables for all processes are allocated as full 4K pages, even for processes that do not need it. Signed-off-by:
