2015-08-20ARM/PCI: Remove msi_controller from struct pci_sys_dataLorenzo Pieralisi
ARM now uses pci_bus->msi to store the msi_controller pointer, so we don't need to save it in struct pci_sys_data, and we don't need to implement pcibios_msi_controller() to get it out of pci_sys_data.

2015-08-20ARM/PCI, designware, xilinx: Use pci_scan_root_bus_msi()Lorenzo Pieralisi
ARM previously stored the msi_controller pointer in its sysdata, struct pci_sys_data, and implemented pcibios_msi_controller() to retrieve it. That made PCI host controller drivers specific to ARM because they had to put the msi_controller pointer in the ARM-specific pci_sys_data. There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the msi_controller pointer to the PCI core. Use this for all ARM systems and for the DesignWare and Xilinx PCI host controller drivers. This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6, Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

2015-08-20ARM: OMAP: wakeupgen: Restore the irq_set_type() mechanismGrygorii Strashko
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 Yamada
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.

2015-08-11ARM: 8410/1: VDSO: fix coarse clock monotonicity regressionNathan Lynch
Since 906c55579a63 ("timekeeping: Copy the shadow-timekeeper over the real timekeeper last") it has become possible on ARM to: - Obtain a CLOCK_MONOTONIC_COARSE or CLOCK_REALTIME_COARSE timestamp via syscall. - Subsequently obtain a timestamp for the same clock ID via VDSO which predates the first timestamp (by one jiffy). This is because ARM's update_vsyscall is deriving the coarse time using the __current_kernel_time interface, when it should really be using the timekeeper object provided to it by the timekeeping core. It happened to work before only because __current_kernel_time would access the same timekeeper object which had been passed to update_vsyscall. This is no longer the case.

2015-08-07ARM: 8409/1: Mark ret_fast_syscall as a functionDrew Richardson
ret_fast_syscall runs when user space makes a syscall. However it needs to be marked as such so the ELF information is correct. Before it was: 101: 8000f300 0 NOTYPE LOCAL DEFAULT 2 ret_fast_syscall But with this change it correctly shows as: 101: 8000f300 96 FUNC LOCAL DEFAULT 2 ret_fast_syscall I see this function when using perf to unwind call stacks from kernel space to user space.

Since the commit "b2c3e38a5471 ARM: redo TTBR setup code for LPAE", the setup code had been reworked. As a result the secondary CPUs failed to come online in Big Endian. As explained by Russell, the new code expected the value in r4/r5 to be the least significant 32bits in r4 and the most significant 32bits in r5. However, in the secondary code, we load this using ldrd, which on BE reverses that. This patch swap r4/r5 after the ldrd. It is done using the xor instructions in order to not use a temporary register.

The "cpus" node cannot be inside the "soc" node, while this works for the CoreSight blocks, the early boot code will look for "cpus" directly under the root node, so this is a hard convention. So move the CPU nodes. Augment the "reg" property to match what is actually in the hardware: 0x300 and 0x301 respectively. Then add an SMP enablement type to be used by the SMP init code, "ste,dbx500-smp". Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
