X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9c8dc1a88c760ec121a260afc9583ec9239497ef;p=linux-beck.git ARM: S5PV210: Fix on MAX_PHYSMEM_BITS on S5PV210/S5PC110. 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.
