Helge Deller 94b7e3a7e8 parisc: Increase kernel stack size to 32kb 
For 64-bit Linux kernels, increase the default kernel stack size
(THREAD_SIZE_ORDER) to 32 kB, in order to avoid kernel crashes which have been
triggered recently when building the debian vtk9 package with gcc 17:

stackcheck: kworker/u128:0 will most likely overflow kernel stack (sp:179a83af0, stk bottom-top:179a80000-179a84000)
Kernel panic - not syncing: low stack detected by irq handler - check messages
CPU: 2 UID: 0 PID: 30760 Comm: kworker/u128:0 Tainted: G W 6.18.46-dirty #1 NONE
Tainted: [W]=WARN
Hardware name: 9000/800/rp3440
Workqueue: writeback wb_workfn (flush-259:0)
