I have trouble parsing this. (What does secondary linear mapping mean?)

s390 has an address space for user (primary address space from 0..4TB/8PB) and a separate 
address space (home space from 0..4TB/8PB) for the kernel. In this home space the kernel
mapping is virtual containing the physical memory as well as vmalloc memory (creating aliases
into the physical one). The kernel text is mapped from _stext to _etext in this mapping.
So I assume this would qualify for HAVE_ARCH_LINEAR_KERNEL_MAPPING ?
