The following commit has been merged into the x86/entry branch of tip: Commit-ID: 4bcffde74b6a2ba992a0617bb6b9be054e7f89a2 Gitweb: https://git.kernel.org/tip/4bcffde74b6a2ba992a0617bb6b9be054e7f89a2 Author: Wei Liu <wei.liu@kernel.org> AuthorDate: Wed, 27 May 2020 12:09:18 Committer: Thomas Gleixner <tglx@linutronix.de> CommitterDate: Thu, 28 May 2020 12:01:24 +02:00 x86/hyperv: Use the correct target for alloc_intr_gate() The idtentry rework causes a boot crash, by erroneously using the C entry point to allocate the interrupt gate for the HYPERVISOR_CALLBACK_VECTOR. Use the ASM entry point to cure this.
