powerpc/xmon: Add kstack base to paca dump
When dumping the paca in xmon we currently show kstack. Although it's not hard it's a bit fiddly to work out what the bounds of the kernel stack should be based on the kstack value. To make life easier and "kstack_base" which is the base (lowest address) of the kernel stack, eg: kstack = 0xc0000000f1a7be30 (0x258) kstack_base = 0xc0000000f1a78000 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
