The plan going forward is to directly import definitions from Hyper-V code without waiting for them to land in the TLFS document. This is a quicker and more maintainable way to import definitions, and is a step toward the eventual goal of exporting headers directly from Hyper-V for use in Linux. This patch series introduces new headers (hvhdk.h, hvgdk.h, etc, see patch #3) derived directly from Hyper-V code. hyperv-tlfs.h is replaced with hvhdk.h (which includes the other new headers) everywhere. No functional change is expected. Summary: Patch 1-2: Minor cleanup patches Patch 3: Add the new headers (hvhdk.h, etc..) in include/hyperv/ Patch 4: Switch to the new headers Signed-off-by: Nuno Das Neves --- Changelog: v2: - Rework the series to simply use the new headers everywhere instead of fiddling around to keep hyperv-tlfs.h used in some places, suggested by Michael Kelley and Easwar Hariharan - Fix compilation errors with some configs by adding missing definitions and changing some names, thanks to Simon Horman for catching those - Add additional definitions to the new headers to support them now replacing hyperv-tlfs.h everywhere - Add additional context in the commit messages for patches #3 and #4 - In patch #2, don't remove indirect includes. Only remove includes which truly aren't used, suggested by Michael Kelley --- Nuno Das Neves (4): hyperv: Move hv_connection_id to hyperv-tlfs.h hyperv: Clean up unnecessary #includes hyperv: Add new Hyper-V headers in include/hyperv hyperv: Switch from hyperv-tlfs.h to hyperv/hvhdk.h arch/arm64/hyperv/hv_core.c | 3 +- arch/arm64/hyperv/mshyperv.c | 4 +- arch/arm64/include/asm/mshyperv.h | 2 +- arch/x86/hyperv/hv_apic.c | 1 - arch/x86/hyperv/hv_init.c | 21 +- arch/x86/hyperv/hv_proc.c | 3 +- arch/x86/hyperv/ivm.c | 1 - arch/x86/hyperv/mmu.c | 1 - arch/x86/hyperv/nested.c | 2 +- arch/x86/include/asm/kvm_host.h | 3 +- arch/x86/include/asm/mshyperv.h | 3 +- arch/x86/include/asm/svm.h | 2 +- arch/x86/kernel/cpu/mshyperv.c | 2 +- arch/x86/kvm/vmx/hyperv_evmcs.h | 2 +- arch/x86/kvm/vmx/vmx_onhyperv.h | 2 +- arch/x86/mm/pat/set_memory.c | 2 - drivers/clocksource/hyperv_timer.c | 2 +- drivers/hv/hv_balloon.c | 4 +- drivers/hv/hv_common.c | 2 +- drivers/hv/hv_kvp.c | 2 +- drivers/hv/hv_snapshot.c | 2 +- drivers/hv/hyperv_vmbus.h | 2 +- include/asm-generic/hyperv-tlfs.h | 9 + include/asm-generic/mshyperv.h | 2 +- include/clocksource/hyperv_timer.h | 2 +- include/hyperv/hvgdk.h | 303 +++++++ include/hyperv/hvgdk_ext.h | 46 + include/hyperv/hvgdk_mini.h | 1295 ++++++++++++++++++++++++++++ include/hyperv/hvhdk.h | 733 ++++++++++++++++ include/hyperv/hvhdk_mini.h | 310 +++++++ include/linux/hyperv.h | 11 +- net/vmw_vsock/hyperv_transport.c | 2 +- 32 files changed, 2729 insertions(+), 52 deletions(-) create mode 100644 include/hyperv/hvgdk.h create mode 100644 include/hyperv/hvgdk_ext.h create mode 100644 include/hyperv/hvgdk_mini.h create mode 100644 include/hyperv/hvhdk.h create mode 100644 include/hyperv/hvhdk_mini.h
