This is a note to let you know that I've just added the patch titled KVM: selftests: riscv: Fix alignment of the guest_hang() function to the 5.17-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: kvm-selftests-riscv-fix-alignment-of-the-guest_hang-.patch and it can be found in the queue-5.17 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 30e3f471a7bcfa2981d56eff6b28f8f9a1223407 Author: Anup Patel <apatel@xxxxxxxxxxxxxxxx> Date: Sat Apr 9 09:15:51 2022 +0530 KVM: selftests: riscv: Fix alignment of the guest_hang() function [ Upstream commit ebdef0de2dbc40e697adaa6b3408130f7a7b8351 ] The guest_hang() function is used as the default exception handler for various KVM selftests applications by setting it's address in the vstvec CSR. The vstvec CSR requires exception handler base address to be at least 4-byte aligned so this patch fixes alignment of the guest_hang() function.
