| * GCC plugin infrastructureEmese Revfy2016-06-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to build the whole kernel with GCC plugins. It was ported from grsecurity/PaX. The infrastructure supports building out-of-tree modules and building in a separate directory. Cross-compilation is supported too. Currently the x86, arm, arm64 and uml architectures enable plugins. The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory there. The plugins compile with these options: * -fno-rtti: gcc is compiled with this option so the plugins must use it too * -fno-exceptions: this is inherited from gcc too * -fasynchronous-unwind-tables: this is inherited from gcc too * -ggdb: it is useful for debugging a plugin (better backtrace on internal errors) * -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h) * -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version variable, plugin-version.h) The infrastructure introduces a new Makefile target called gcc-plugins. It supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++). This script also checks the availability of the included headers in scripts/gcc-plugins/gcc-common.h. The gcc-common.h header contains frequently included headers for GCC plugins and it has a compatibility layer for the supported gcc versions. The gcc-generate-*-pass.h headers automatically generate the registration structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes. Note that 'make clean' keeps the *.so files (only the distclean or mrproper targets clean all) because they are needed for out-of-tree modules. Based on work created by the PaX Team.

| * | KVM: arm64: vgic-its: Introduce new KVM ITS deviceAndre Przywara2016-07-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new KVM device that represents an ARM Interrupt Translation Service (ITS) controller. Since there can be multiple of this per guest, we can't piggy back on the existing GICv3 distributor device, but create a new type of KVM device. On the KVM_CREATE_DEVICE ioctl we allocate and initialize the ITS data structure and store the pointer in the kvm_device data. Upon an explicit init ioctl from userland (after having setup the MMIO address) we register the handlers with the kvm_io_bus framework. Any reference to an ITS thus has to go via this interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we move towards a selectable HYP VA range, it is obvious that we don't want to test a variable to find out if we need to use the bottom VA range, the top VA range, or use the address as is (for VHE). Instead, we can expand our current helper to generate the right mask or nop with code patching. We default to using the top VA space, with alternatives to switch to the bottom one or to nop out the instructions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __hyp_panic_string is passed via the HYP panic code to the panic function, and is being "upgraded" to a kernel address, as it is referenced by the HYP code (in a PC-relative way). This is a bit silly, and we'd be better off obtaining the kernel address and not mess with it at all. This patch implements this with a tiny bit of asm glue, by forcing the string pointer to be read from the literal pool.

No need to mention the names of those who suffered, the git log is singing their praises. Thankfully, we now have a much more maintainable implementation, and we can safely put the grumpy old GIC to rest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra210 XUSB subsystem has 3 power partitions which are XUSBA (super-speed logic), XUSBB (USB device logic) and XUSBC (USB host logic). Populate the device-tree nodes for these XUSB partitions. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

Also add the 'i2c-bus' node for the DPAUX nodes so that the I2C driver core does not attempt to parse the pinctrl state nodes. Populate the nodes for the pinctrl clients of the DPAUX pin controller. There are two clients for each DPAUX instance, namely the SOR and one of the I2C adapters. The SOR clients may used the DPAUX pins in either AUX or I2C modes and so for these devices we don't define any of the generic pinctrl states (default, idle, etc) because the SOR driver will directly set the state needed. For I2C clients only the I2C mode is used and so we can simplify matters by using the generic pinctrl states for default and idle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XUSB mailbox interrupt for Tegra210 is 40 and not 49 which is for the XUSB pad controller. For some Tegra210 boards, this is causing USB connect and disconnect events to go undetected. Fix this by changing the interrupt number for the XUSB mailbox to 40.
