Subject[PATCH 2/2] MIPS: Remove a warning when PHYS_OFFSET is 0x0
Date
Rewrite the comparison in `else if` statement, case where `min_low_pfn >
ARCH_PFN_OFFSET` has already been checked in the first `if` statement:

if (min_low_pfn > ARCH_PFN_OFFSET) {

Fix non-fatal warning:

arch/mips/kernel/setup.c: In function ‘bootmem_init’:
arch/mips/kernel/setup.c:461:25: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
} else if (min_low_pfn < ARCH_PFN_OFFSET) {
^
