x86, vmlinux.lds: unify first part of initdata
32-bit:
- Move definition of __init_begin outside output_section
because it covers more than one section
- Move ALIGN() for end-of-section inside .smp_locks output section.
Same effect but the intent is better documented that
we need both start and end aligned.
64-bit:
- Move ALIGN() outside output section in .init.setup
- Deleted unused __smp_alt_* symbols
None of the above should result in any functional change.
[ Impact: refactor and unify linker script ]
