Make vmlinux.lds almost readable.
When going through the file fixed the following:
- Use PAGE_SIZE as replacement for hardcoded 4096
- Moves label definitions inside {} to avoid ld alignment
that may be added between label and section

Build tested only.
Will do this for all archs over time.
PS. I expect that Davem will apply this and a similar
one for sparc64 I already sent.
