These stacks are appropriate for threads that run purely in supervisor mode, and also as stacks for interrupt and exception handling. Two new arch defines are introduced: - ARCH_KERNEL_STACK_GUARD_SIZE - ARCH_KERNEL_STACK_OBJ_ALIGN New public declaration macros: - K_KERNEL_STACK_RESERVED - K_KERNEL_STACK_EXTERN - K_KERNEL_STACK_DEFINE - K_KERNEL_STACK_ARRAY_DEFINE - K_KERNEL_STACK_MEMBER - K_KERNEL_STACK_SIZEOF If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_* are equivalent. Separately generated privilege elevation stacks are now declared like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
