Hi I was going through arm vmlinux script file. and i found below statements
/* * first, the init task union, aligned * to an 8192 byte boundary. */
INIT_TASK_DATA(THREAD_SIZE)
#define INIT_TASK_DATA(align) \ . = ALIGN(align); \ *(.data..init_task)
As i know we align data structures on a n byte boundary to save access time and for speed execution but i did not understand why do we need to align this particular data structure on a 8192 byte boundary.
sometimes it will be on 1024 or 2048 byte boundary.
Any inputs would be appreciated!!!
