Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
There is nothing userspace can do with this value. In the kernel is always combined with AT_VECTOR_SIZE_BASE, which is not exposed to userspace and also changes from time to time. Move the symbol to a kernel-internal header.
