[PATCH v3 4/4] Drivers: hv: Enable CONFIG_HYPERV on ARM64

Update drivers/hv/Kconfig so CONFIG_HYPERV can be selected on ARM64, causing the Hyper-V specific code to be built. Signed-off-by: Michael Kelley --- drivers/hv/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/hv/Kconfig b/drivers/hv/Kconfig index 97954f5..c3

[PATCH v3 3/4] Drivers: hv: vmbus: Add hooks for per-CPU IRQ

Add hooks to enable/disable a per-CPU IRQ for VMbus. These hooks are in the architecture independent setup and shutdown paths for Hyper-V, and are needed by Linux guests on Hyper-V on ARM64. The x86/x64 implementation is null because VMbus interrupts on x86/x64 don't use an IRQ. Signed-off-by: Mi

[PATCH v3 0/4] Subject: Enable Linux guests on Hyper-V on ARM64

This series enables Linux guests running on Hyper-V on ARM64 hardware. New ARM64-specific code in arch/arm64/hyperv initializes Hyper-V, including its synthetic clocks and hypercall mechanism. Existing architecture independent drivers for Hyper-V's VMbus and synthetic devices just work when built f

[PATCH v3 2/4] arm64: hyperv: Add support for Hyper-V as a hypervisor

Add ARM64-specific code to enable Hyper-V. This code includes: * Detecting Hyper-V and initializing the guest/Hyper-V interface * Setting up Hyper-V's synthetic clocks * Making hypercalls using the HVC instruction * Setting up VMbus and stimer0 interrupts * Setting up kexec and crash handlers This

[PATCH v3 1/4] arm64: hyperv: Add core Hyper-V include files

hyperv-tlfs.h defines Hyper-V interfaces from the Hyper-V Top Level Functional Spec (TLFS). The TLFS is distinctly oriented to x86/x64, and Hyper-V has not separated out the architecture-dependent parts into x86/x64 vs. ARM64. So hyperv-tlfs.h includes information for ARM64 that is not yet formally

[PATCH][staging-next] drivers: staging: cedrus: find ctx before dereferencing it ctx

From: Colin Ian King Currently if count is an invalid value the v4l2_info message will dereference a null ctx pointer to get the dev information. Fix this by finding ctx first and then checking for an invalid count, this way ctxt will be non-null hence avoiding the null pointer dereference. Dete
