Subject: parisc: Increase initial kernel mapping size
From: Helge Deller <deller@xxxxxx>
commit 65bf34f59594c11f13d371c5334a6a0a385cd7ae upstream.
Increase the initial kernel default page mapping size for 64-bit kernels to
64 MB and for 32-bit kernels to 32 MB.
Due to the additional support of ftrace, tracepoint and huge pages the kernel
size can exceed the sizes we used up to now.
