Now that the mtd core supports more then 64 ecc bytes we can use it instead of some a custom hack in the jz4740 nand driver. This patch removes the custom {read,write}_page handlers from the jz4740 nand driver. Thus the driver will now fallback to the default handlers from the nand core.

The [vk][cmz]alloc(_node) family of functions return void pointers which it's completely unnecessary/pointless to cast to other pointer types since that happens implicitly.

Grant Likely authored
MTD_OF_PARTS should be possible on all architectures, not just powerpc and microblaze, and it probably should not be a user selectable option. Neither does it need to be in a separate module. Also, rework MTD Kconfig to group options dependant on MTD_PARTITIONS into a if/endif block. Do the same for MTD_REDBOOT_PARTS.

The definition of PAGE_CACHE_MASK in <linux/pagemap.h> is needed to use MAX_RW_COUNT, and on x86-64 that gets done indirectly through the architecture header includes. But on MIPS and s390 that doesn't happen, and we need to make sure that fs/compat.c includes pagemap.h explicitly. Introduced in commit 435f49a5 ("readv/writev: do the same MAX_RW_COUNT truncation that read/write does").

In commit 2a48fc0a ('block: autoconvert trivial BKL users to private mutex'), Arnd replaced the BKL usage with a mutex. However, Maxim has already provided a better fix in commit 480792b7 ('mtd: blktrans: kill BKL'), which was simply to remove the BKL without replacing it — since he'd already made it do all necessary locking for itself.

Currently, text_poke_smp() passes a NULL as the third argument to __stop_machine(), which will only run stop_machine_text_poke() on 1 cpu. Change NULL -> cpu_online_mask, as stop_machine_text_poke() is intended to be run on all cpus. I actually didn't notice any problems with stop_machine_text_poke() only being called on 1 cpu, but found this via code inspection.

Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer). This causes dereferencing of NULL pointer at boot time and a kernel panic.

If the board has a debug uart the user is given a choice of which uart to use. The user can also select NONE, which means not to use one. In most of our header files when NONE is selected nothing is defined for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile failure in debug-macro.S which expect something to be defined there. Example of the failure, arch/arm/kernel/built-in.o: In function `hexbuf': linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS' linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE' This fixes the compile failure by adding an ifdef to debug-macro.S that removes all the debug uart code in the case of NONE.
