powerpc/64e: Reorganise virtual memory
Reduce the size of IO map in order to leave the last
quarter of virtual MAP for KASAN shadow mapping.
This gives the following layout.
+------------------------+ Kernel virtual map end (0xc000200000000000)
| |
| 16TB (unused) |
| |
+------------------------+ Kernel IO map end
| |
| 16TB of IO map |
| |
+------------------------+ Kernel IO map start
| |
| 16TB of vmemmap |
| |
+------------------------+ Kernel vmemmap start
| |
| 16TB of vmap |
| |
+------------------------+ Kernel virt start (0xc000100000000000)
| |
| 64TB of linear mem |
| |
+------------------------+ Kernel linear (0xc.....)
