From: Jork Loeser Date: Wed, 8 Apr 2026 01:36:39 +0000 (-0700) Subject: x86/hyperv: move stimer cleanup to hv_machine_shutdown() X-Git-Tag: v7.1-rc1~51^2~1 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f7ce370b525a02127527b0f54ee877413705a709;p=thirdparty%2Fkernel%2Flinux.git x86/hyperv: move stimer cleanup to hv_machine_shutdown() Move hv_stimer_global_cleanup() from vmbus's hv_kexec_handler() to hv_machine_shutdown() in the platform code. This ensures stimer cleanup happens before the vmbus unload, which is required for root partition kexec to work correctly.
