They need only support limited call-tree depth and must fit into the low core, so they are typically smaller than the ISR stacks. # We should really only have to provide one of the following two values, # but a bug in the Zephyr SDK for x86 precludes the use of division in # the assembler.

Must be a multiple of 16 to main stack alignment. Note that CONFIG_ISR_SUBSTACK_SIZE * CONFIG_ISR_DEPTH must be equal to CONFIG_ISR_STACK_SIZE. endif # X86_LONGMODE
