csky: bugfix tlb_get_pgd error. It's wrong to mask/unmask highest bit in addr to translate the vaddr to paddr. We should use PAGE_OFFSET and PHYS_OFFSET. Wrong implement: return ((get_pgd()|(1<<31)) - PHYS_OFFSET) & ~1; When PHYS_OFFSET=0xc0000000 and get_pgd() return 0xe0000000, it'll return 0x60000000. It's wrong and should be 0xa0000000. Now correct it to: return ((get_pgd() - PHYS_OFFSET) & ~1) + PAGE_OFFSET; Signed-off-by: Guo Ren <ren_guo@c-sky.com>
