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. a000000100e80480 d secpath_cachep a000000100e80488 D init_uts_ns Signed-off-by: Shaohua Li <shaohua.li@intel.com> Cc: "H.
