Analyze and fix the following issue in the Linux kernel code: ARM: S5PV210: Fix on MAX_PHYSMEM_BITS on S5PV210/S5PC110.
Problem Details: 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. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

Analyze and fix the following issue in the Linux kernel code: omap: Fix DEBUG_LL uart to access phys addr when MMU isn't enable
Problem Details: Now we use a memory address to store the debug port info, So we need to read/write this address when we choose DEBUG_LL. When MMU isn't enable(I.E. the begining part of init stage of the linux kernel boot), we need to access physical address instead of virtual address, otherwise the kernel will crash. ...
