include/asm-generic/vmlinux.lds.h: make readmostly section correctly align
The readmostly section should end at a cacheline aligned address,
otherwise the last several data might share cachline with other data and
make the readmostly data still have cache bounce.
For example, in ia64, secpath_cachep is the last readmostly data, and it
shares cacheline with init_uts_ns.
