Init 'sregs' to avoid Valgrind complaints about uninitialized bytes from kvmppc_put_books_sregs(): ==54059== Thread 3: ==54059== Syscall param ioctl(generic) points to uninitialised byte(s) ==54059== at 0x55864E4: ioctl (in /usr/lib64/libc.so.6) ==54059== by 0xD1FA23: kvm_vcpu_ioctl (kvm-all.c:3053) ==54059== by 0xAFB18B: kvmppc_put_books_sregs (kvm.c:891) ==54059== by 0xAFB47B: kvm_arch_put_registers (kvm.c:949) ==54059== by 0xD1EDA7: do_kvm_cpu_synchronize_post_init (kvm-all.c:2766) ==54059== by 0x481AF3: process_queued_cpu_work (cpus-common.c:343) ==54059== by 0x4EF247: qemu_wait_io_event_common (cpus.c:412) ==54059== by 0x4EF343: qemu_wait_io_event (cpus.c:436) ==54059== by 0xD21E83: kvm_vcpu_thread_fn (kvm-accel-ops.c:54) ==54059== by 0xFFEBF3: qemu_thread_start (qemu-thread-posix.c:556) ==54059== by 0x54E6DC3: start_thread (in /usr/lib64/libc.so.6) ==54059== by 0x5596C9F: clone (in /usr/lib64/libc.so.6) ==54059== Address 0x799d1cc is on thread 3's stack ==54059== in frame #2, created by kvmppc_put_books_sregs (kvm.c:851) ==54059== Uninitialised value was created by a stack allocation ==54059== at 0xAFAEB0: kvmppc_put_books_sregs (kvm.c:851) This happens because Valgrind does not consider the 'sregs' initialization done by kvm_vcpu_ioctl() at the end of the function.
