2012-05-16fork: move the real prepare_to_copy() users to arch_dup_task_struct()Suresh Siddha
Historical prepare_to_copy() is mostly a no-op, duplicated for majority of the architectures and the rest following the x86 model of flushing the extended register state like fpu there.

2012-05-11gpiolib/arches: Centralise bolierplate asm/gpio.hMark Brown
Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h provide a Kconfig symbol which architectures must select in order to include gpio.h and for other architectures just provide the trivial implementation directly. This makes it much easier to do gpiolib updates and is also a step towards making gpiolib APIs available on every architecture. For architectures with existing boilerplate code leave a stub header in place which warns on direct inclusion of asm/gpio.h and includes linux/gpio.h to catch code that's doing this. Direct inclusion of asm/gpio.h has long been deprecated.

2012-05-05blackfin: Use generic init_taskThomas Gleixner
Same code. Use the generic version. The special Makefile treatment is pointless anyway as init_task.o contains only data which is handled by the linker script.

2012-04-26blackfin: fix ifdef fustercluck in mach-bf538/boards/ezkit.cPaul Gortmaker
This file has lots and lots of ifdef, around structure decls and structure usages. The failure issue was that we would build the BF538-EZKIT_defconfig and get: arch/blackfin/mach-bf538/boards/ezkit.c:924:3: error: 'bfin_lq035q1_device' undeclared here (not in a function) even though the same ifdef _appeared_ to enable both the struct declaration and the code that used it. Yet cpp was telling us we didn't have the struct, but we still had the usage of it. However, _appeared_ is the operative word. After marking all the anonymous #endif with their parent #ifdef config options, it was _then_ clear that there was a misplaced #endif that was hiding the struct declaration. The real guts of the patch boils down to this: -#endif +#endif /* CONFIG_MTD_M25P80 */ +#endif /* CONFIG_SPI_BFIN5XX */ [...] -#endif /* spi master and devices */ but since I had to tag the #endif with their respective #ifdef options to find this misplaced SPI endif, it would be silly to then go and delete them all. So they stay. Cc: Sonic Zhang <sonic.zhang@analog.com> Cc: Bob Liu <lliubbo@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
