[PATCH] ARM: S5PV210: Fix on MAX_PHYSMEM_BITS on S5PV210/S5PC110.

From: Kukjin Kim <hidden>
Date: 2010-07-12 06:31:09
Also in: linux-samsung-soc
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

This patch fixes on MAX_PHYSMEM_BITS for Sparsemem on S5PV210/S5PC110.
Because physical memory can be located from 0x20000000 to 0x7fffffff,
so MAX_PHYSMEM_BITS is 31 and not 32.

NOTE:
Russell pointed this out from mailing list. So added him to 'Reported-by'.
If any problem about this, please kindly let me know.
Thanks.
