Stefano Stabellini 3c1963b5e7 arm/xen: fix xen_vcpu_info allocation alignment ... [ Upstream commit 7bf9a6b46549852a37e6d07e52c601c3c706b562 ] xen_vcpu_info is a percpu area than needs to be mapped by Xen. Currently, it could cross a page boundary resulting in Xen being unable to map it: [ 0.567318] kernel BUG at arch/arm64/xen/../../arm/xen/enlighten.c:164! [ 0.574002] Internal error: Oops - BUG: 00000000f2000800 [#1] PREEMPT SMP Fix the issue by using __alloc_percpu and requesting alignment for the memory allocation.
