Fix sent to kernel team mailing list for review and inclusion into 4.4 Xenial linux kernel: https://lists.ubuntu.com/archives/kernel- team/2016-February/072324.html
** Description changed: Since 4.4, I have not been able to boot GNU Hurd Kernels using KVM QEMU. I tracked this regression down to commit e8dd2d2d641c ("Silence compiler warning in arch/x86/kvm/emulate.c", 2015-09-06) This has been recently fixed with upstream commit 0c1d77f4ba5cc9c05a29adca3d6466cdf4969b70: - KVM: x86: fix conversion of addresses to linear in 32-bit protected mode - - Commit e8dd2d2d641c ("Silence compiler warning in arch/x86/kvm/emulate.c", - 2015-09-06) broke boot of the Hurd. The bug is that the "default:" - case actually could modify "la", but after the patch this change is - not reflected in *linear. - - The bug is visible whenever a non-zero segment base causes the linear - address to wrap around the 4GB mark. - - Fixes: e8dd2d2d641cb2724ee10e76c0ad02e04289c017 - Cc: sta...@vger.kernel.org - Reported-by: Aurelien Jarno <aurel...@aurel32.net> - Tested-by: Aurelien Jarno <aurel...@aurel32.net> - Signed-off-by: Paolo Bonzini <pbonz...@redhat.com> + KVM: x86: fix conversion of addresses to linear in 32-bit protected mode + + Commit e8dd2d2d641c ("Silence compiler warning in arch/x86/kvm/emulate.c", + 2015-09-06) broke boot of the Hurd.
