Oddly enough, removing the alloc_pages() check didn't do anything to text on a NUMA=y config, either:
dave@kernel:~/work/mhp-build$ size i386-numaq-sparse.?/vmlinux text data bss dec hex filename 3460792 449336 1626112 5536240 5479f0 i386-numaq-sparse.0/vmlinux 3460792 449336 1626112 5536240 5479f0 i386-numaq-sparse.1/vmlinux 3460776 449336 1626112 5536224 5479e0 i386-numaq-sparse.2/vmlinux
Here's bloatmeter from removing the alloc_pages_node() check:
