bpf: hardcode BPF_PROG_PACK_SIZE to 2MB * num_possible_nodes()
[ Upstream commit d6170e4aaf86424c24ce06e355b4573daa891b17 ]
On some architectures like ARM64, PMD_SIZE can be really large in some
configurations. Like with CONFIG_ARM64_64K_PAGES=y the PMD_SIZE is
512MB.
Use 2MB * num_possible_nodes() as the size for allocations done through
the prog pack allocator. On most architectures, PMD_SIZE will be equal
to 2MB in case of 4KB pages and will be greater than 2MB for bigger page
sizes.
