Andrew Morton reported a strange looking kmemcheck warning: WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88004fba6c20) 0000000000000000310000000000000000000000000000002413000000c9ffff u u u u u u u u u u u u u u u u i i i i i i i i u u u u u u u u [<ffffffff810af3aa>] kmemleak_scan+0x25a/0x540 [<ffffffff810afbcb>] kmemleak_scan_thread+0x5b/0xe0 [<ffffffff8104d0fe>] kthread+0x9e/0xb0 [<ffffffff81003074>] kernel_thread_helper+0x4/0x10 [<ffffffffffffffff>] 0xffffffffffffffff The above printout is missing register dump completely. The problem here is that the output comes from syslog which doesn't show KERN_INFO log-level messages. We didn't see this before because both of us were testing on 32-bit kernels which use the _default_ log-level. Fix that up by explicitly using KERN_DEFAULT log-level for __show_regs() printks.
