2015-01-26ACPICA: Resources: Provide common part for struct acpi_resource_address ↵Lv Zheng
structures. struct acpi_resource_address and struct acpi_resource_extended_address64 share substracts just at different offsets. To unify the parsing functions, OSPMs like Linux need a new ACPI_ADDRESS64_ATTRIBUTE as their substructs, so they can extract the shared data. This patch also synchronizes the structure changes to the Linux kernel. The usages are searched by matching the following keywords: 1. acpi_resource_address 2. acpi_resource_extended_address 3. ACPI_RESOURCE_TYPE_ADDRESS 4. ACPI_RESOURCE_TYPE_EXTENDED_ADDRESS And we found and fixed the usages in the following files: arch/ia64/kernel/acpi-ext.c arch/ia64/pci/pci.c arch/x86/pci/acpi.c arch/x86/pci/mmconfig-shared.c drivers/xen/xen-acpi-memhotplug.c drivers/acpi/acpi_memhotplug.c drivers/acpi/pci_root.c drivers/acpi/resource.c drivers/char/hpet.c drivers/pnp/pnpacpi/rsparser.c drivers/hv/vmbus_drv.c Build tests are passed with defconfig/allnoconfig/allyesconfig and defconfig+CONFIG_ACPI=n.

2014-03-04x86: Hyperv: Cleanup the irq messThomas Gleixner
The vmbus/hyperv interrupt handling is another complete trainwreck and probably the worst of all currently in tree. If CONFIG_HYPERV=y then the interrupt delivery to the vmbus happens via the direct HYPERVISOR_CALLBACK_VECTOR. So far so good, but: The driver requests first a normal device interrupt. The only reason to do so is to increment the interrupt stats of that device interrupt. For no reason it also installs a private flow handler. We have proper accounting mechanisms for direct vectors, but of course it's too much effort to add that 5 lines of code. Aside of that the alloc_intr_gate() is not protected against reallocation which makes module reload impossible. Solution to the problem is simple to rip out the whole mess and implement it correctly. First of all move all that code to arch/x86/kernel/cpu/mshyperv.c and merily install the HYPERVISOR_CALLBACK_VECTOR with proper reallocation protection and use the proper direct vector accounting mechanism.

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.
