[Xen-devel] [PATCH 2/4] xen/link: Link .data.schedulers and CONSTRUCTERS in more appropriate locations

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Neither of these should live in .data

 * .data.schedulers is only ever read, so is moved into .rodata
 * CONSTRUCTORS is only ever read, and only at boot, so is moved to beside
   .init.rodata
