I'm not sure there is much value in
keeping 4*PAGE_SIZE for larger page sizes but I agree that the current
16K value doesn't work well with 64K pages.

Arnd told there will be a workaround for arm v6 caches. Than this
header will not be needed at all. Until that, this is simpliest
fix as it doesn't affect userspace.

I think we should do whatever matches user space: There is no harm
in going to 256KB instead of 64KB if current glibc already uses
4*getpagetsize() for a kernel with native 64K pages.
