Component Type: kbuild config

More info: An arch should select this symbol if it can support kernel stacks in vmalloc space. This means: - vmalloc space must be large enough to hold many kernel stacks. This may rule out many 32-bit architectures. - Stacks in vmalloc space need to work reliably. For example, if vmap page tables are created on demand, either this mechanism needs to work while the stack points to a virtual address with unpopulated page tables or arch code (switch_to() and switch_mm(), most likely) needs to ensure that the stack's page table entries are populated before running on a possibly unpopulated stack. - If the stack overflows into a guard page, something reasonable should happen. The definition of "reasonable" is flexible, but instantly rebooting without logging anything would be unfriendly.
