2015-08-20ARM: OMAP: wakeupgen: Restore the irq_set_type() mechanismGrygorii Strashko1-0/+1
The conversion of the wakeupgen irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The wakeupgen irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the wakeupgen irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.

2015-08-18ARM: 8418/1: add boot image dependencies to not generate invalid imagesMasahiro Yamada1-0/+3
U-Boot is often used to boot the kernel on ARM boards, but uImage is not built by "make all", so we are often inclined to do "make all uImage" to generate DTBs, modules and uImage in a single command, but we should notice a pitfall behind it. In fact, "make all uImage" could generate an invalid uImage if it is run with the parallel option (-j). You can reproduce this problem with the following procedure: [1] First, build "all" and "uImage" separately. You will get a valid uImage $ git clean -f -x -d $ export CROSS_COMPILE=<your-tools-prefix> $ make -s -j8 ARCH=arm multi_v7_defconfig $ make -s -j8 ARCH=arm all $ make -j8 ARCH=arm UIMAGE_LOADADDR=0x80208000 uImage CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date.

Besides, "Kernel: arch/arm/boot/zImage is ready" is displayed twice, before and after the uImage log. The root cause of this is the race condition between zImage and uImage. Actually, uImage depends on zImage, but the dependency between the two is only described in arch/arm/boot/Makefile. Because arch/arm/boot/Makefile is not included from the top-level Makefile, it cannot know the dependency between zImage and uImage. Consequently, when we run make with the parallel option, Kbuild updates vmlinux first, and then two different threads descends into the arch/arm/boot/Makefile almost at the same time, one for updating zImage and the other for uImage. While one thread is re-generating zImage, the other also tries to update zImage before creating uImage on top of that. zImage is overwritten by the slower thread and then uImage is created based on the half-written zImage. This is the reason why "Kernel: arch/arm/boot/zImage is ready" is displayed twice, and a broken uImage is created. The same problem could happen on bootpImage. This commit adds dependencies among Image, zImage, uImage, and bootpImage to arch/arm/Makefile, which is included from the top-level Makefile.
