Subject: parisc: Increase initial kernel mapping size

From: Helge Deller <[email protected]>

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.
