Hi, I see the definition of PAGE_OFFSET on m68k platform like that: #define PAGE_OFFSET (PAGE_OFFSET_RAW) #ifdef CONFIG_MMU #ifndef CONFIG_SUN3 #define PAGE_OFFSET_RAW 0x00000000 #else #define PAGE_OFFSET_RAW 0x0E000000 #endif #else #define PAGE_OFFSET_RAW CONFIG_RAMBASE #endif In my understanding, the kernel page mapping depends on PAGE_OFFSET. For example, if PAGE_OFFSET is 0x00000000 (assuming 256M memory), the kernel virtual address will be at (0x00000000 - 0x10000000), right? Could this incur some side effect? I see the definition of PAGE_OFFSET is 0xc0000000 on much platforms.
