BugLink: http://bugs.launchpad.net/bugs/1875456 As bug description. All the patches are clean cherry-picks or straightforward context adjustments. I made a series of simple tests and stability tests with stress-ng and not issues were found. I was able to force a kernel dump with kdump. --- Sunil Muthuswamy (3): Drivers: HV: Send one page worth of kmsg dump over Hyper-V during panic Drivers: hv: vmus: Fix the check for return value from kmsg get dump buffer Drivers: hv: vmbus: Fix the issue with freeing up hv_ctl_table_hdr Tianyu Lan (6): x86/Hyper-V: Unload vmbus channel in hv panic callback x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump x86/Hyper-V: Trigger crash enlightenment only once during system crash. x86/Hyper-V: Report crash register data or kmsg before running crash kernel x86/Hyper-V: Report crash register data when sysctl_record_panic_msg is not set x86/Hyper-V: Report crash data in die() when panic_on_oops is set Documentation/sysctl/kernel.txt | 11 +++ arch/x86/hyperv/hv_init.c | 33 ++++++- arch/x86/include/asm/hyperv-tlfs.h | 5 +- arch/x86/include/asm/mshyperv.h | 3 +- arch/x86/kernel/cpu/mshyperv.c | 10 ++ drivers/hv/channel_mgmt.c | 3 + drivers/hv/vmbus_drv.c | 145 +++++++++++++++++++++++++++-- 7 files changed, 198 insertions(+), 12 deletions(-)
