I get the following
In file included from arch/x86/kvm/mmu.c:2856: arch/x86/kvm/paging_tmpl.h: In function ‘paging32_walk_addr_generic’: arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function In file included from arch/x86/kvm/mmu.c:2852: arch/x86/kvm/paging_tmpl.h: In function ‘paging64_walk_addr_generic’: arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function
when building -rc1. It looks like it is caused by 6e2ca7d1802bf8ed9908435e34daa116662e7790 and sticking uninitialized_var() around the ptep_user declaration looks like the easiest solution. But the code should still be audited by someone who's familiar with it whether shutting up the compiler doesn't cause an actual bug.
Thanks.
