configname: CONFIG_HAVE_ALIGNED_STRUCT_PAGE

Linux Kernel Configuration
└─>HAVE_ALIGNED_STRUCT_PAGE
In linux kernel since version 3.1 (release Date: 2011-10-24)  
This makes sure that struct pages are double word aligned and that
e.g. the SLUB allocator can perform double word atomic operations
on a struct page for better performance. However selecting this
might increase the size of a struct page by a word.
