Hi Linus, The following changes since commit 64570fbc14f8d7cb3fe3995f20e26bc25ce4b2cc: Linux 5.15-rc5 (2021-10-10 17:01:59 -0700) are available in the Git repository at: ssh://git@xxxxxxxxxxxxxxxxxxx/pub/scm/linux/kernel/git/hyperv/linux.git tags/hyperv-next-signed-20211102 for you to fetch changes up to 285f68afa8b20f752b0b7194d54980b5e0e27b75: x86/hyperv: Protect set_hv_tscchange_cb() against getting preempted (2021-10-28 11:59:13 +0000) There are two merges from the tip tree: one is because of Tianyu's patches went in via tip/x86/sev, the other is because a tree-wide cleanup in tip/x86/cc conflicted with Tianyu's patch. Instead of requiring you to fix up I thought I'd just do it myself. Thanks, Wei. ---------------------------------------------------------------- hyperv-next for 5.16 - Initial patch set for Hyper-V isolation VM support (Tianyu Lan) - Fix a warning on preemption (Vitaly Kuznetsov) - A bunch of misc cleanup patches. ---------------------------------------------------------------- Jiapeng Chong (1): x86/hyperv: Remove duplicate include Lv Ruyi (1): Drivers: hv : vmbus: Adding NULL pointer check Michael Kelley (1): Drivers: hv: vmbus: Remove unused code to check for subchannels Tianyu Lan (9): x86/sev: Expose sev_es_ghcb_hv_call() for use by HyperV x86/hyperv: Initialize GHCB page in Isolation VM x86/hyperv: Initialize shared memory boundary in the Isolation VM. x86/hyperv: Add new hvcall guest address host visibility support Drivers: hv: vmbus: Mark vmbus ring buffer visible to host in Isolation VM x86/hyperv: Add Write/Read MSR registers via ghcb page x86/hyperv: Add ghcb hvcall support for SNP VM Drivers: hv: vmbus: Add SNP support for VMbus channel initiate message Drivers: hv: vmbus: Initialize VMbus ring buffer for Isolation VM Vitaly Kuznetsov (1): x86/hyperv: Protect set_hv_tscchange_cb() against getting preempted Wan Jiabing (1): x86/hyperv: Remove duplicated include in hv_init Wei Liu (2): Merge remote-tracking branch 'tip/x86/sev' into hyperv-next Merge remote-tracking branch 'tip/x86/cc' into hyperv-next arch/Kconfig | 3 + arch/powerpc/include/asm/mem_encrypt.h | 5 - arch/powerpc/platforms/pseries/Kconfig | 1 + arch/powerpc/platforms/pseries/Makefile | 2 + arch/powerpc/platforms/pseries/cc_platform.c | 26 +++ arch/powerpc/platforms/pseries/svm.c | 5 +- arch/s390/include/asm/mem_encrypt.h | 2 - arch/x86/Kconfig | 1 + arch/x86/hyperv/Makefile | 2 +- arch/x86/hyperv/hv_init.c | 82 ++++++-- arch/x86/hyperv/ivm.c | 289 +++++++++++++++++++++++++++ arch/x86/include/asm/hyperv-tlfs.h | 17 ++ arch/x86/include/asm/io.h | 8 + arch/x86/include/asm/kexec.h | 2 +- arch/x86/include/asm/mem_encrypt.h | 12 +- arch/x86/include/asm/mshyperv.h | 70 +++++-- arch/x86/include/asm/sev.h | 6 + arch/x86/kernel/Makefile | 6 + arch/x86/kernel/cc_platform.c | 69 +++++++ arch/x86/kernel/cpu/mshyperv.c | 5 + arch/x86/kernel/crash_dump_64.c | 4 +- arch/x86/kernel/head64.c | 9 +- arch/x86/kernel/kvm.c | 3 +- arch/x86/kernel/kvmclock.c | 4 +- arch/x86/kernel/machine_kexec_64.c | 19 +- arch/x86/kernel/pci-swiotlb.c | 9 +- arch/x86/kernel/relocate_kernel_64.S | 2 +- arch/x86/kernel/sev-shared.c | 68 ++++--- arch/x86/kernel/sev.c | 40 ++-- arch/x86/kernel/traps.c | 2 +- arch/x86/kvm/svm/svm.c | 3 +- arch/x86/mm/ioremap.c | 18 +- arch/x86/mm/mem_encrypt.c | 55 ++--- arch/x86/mm/mem_encrypt_identity.c | 18 +- arch/x86/mm/pat/set_memory.c | 24 ++- arch/x86/platform/efi/efi_64.c | 9 +- arch/x86/realmode/init.c | 8 +- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 4 +- drivers/gpu/drm/drm_cache.c | 4 +- drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 4 +- drivers/gpu/drm/vmwgfx/vmwgfx_msg.c | 6 +- drivers/hv/Kconfig | 1 + drivers/hv/channel.c | 72 ++++--- drivers/hv/channel_mgmt.c | 34 ---- drivers/hv/connection.c | 101 +++++++++- drivers/hv/hv.c | 82 ++++++-- drivers/hv/hv_common.c | 12 ++ drivers/hv/hyperv_vmbus.h | 2 + drivers/hv/ring_buffer.c | 57 ++++-- drivers/iommu/amd/init.c | 7 +- drivers/iommu/amd/iommu.c | 3 +- drivers/iommu/amd/iommu_v2.c | 3 +- drivers/iommu/iommu.c | 3 +- drivers/net/hyperv/hyperv_net.h | 5 +- drivers/net/hyperv/netvsc.c | 15 +- drivers/uio/uio_hv_generic.c | 18 +- fs/proc/vmcore.c | 6 +- include/asm-generic/hyperv-tlfs.h | 1 + include/asm-generic/mshyperv.h | 20 +- include/linux/cc_platform.h | 88 ++++++++ include/linux/hyperv.h | 25 +-- include/linux/mem_encrypt.h | 4 - kernel/dma/swiotlb.c | 4 +- 63 files changed, 1150 insertions(+), 339 deletions(-) create mode 100644 arch/powerpc/platforms/pseries/cc_platform.c create mode 100644 arch/x86/hyperv/ivm.c create mode 100644 arch/x86/kernel/cc_platform.c create mode 100644 include/linux/cc_platform.h
