commit 5f74f820f6fc844b95f9e5e406e0a07d97510420 upstream.
Matoro reported various userspace crashes on the parisc platform with kernel
6.6 and bisected it to commit 3033cd430768 ("parisc: Use generic mmap top-down
layout and brk randomization").
That commit switched parisc to use the common infrastructure to calculate
mmap_base, but missed that the mmap_base() function takes care for
architectures where the stack grows downwards only.
Fix the mmap_base() calculation to include the stack-grows-upwards case
and thus fix the userspace crashes on parisc.
