passed to sysctl_createv() actually matches the declared type for the item itself. In the places where the caller specifies a function and a structure address (typically the 'softc') an explicit (void *) cast is now needed. Fixes bugs in sys/dev/acpi/asus_acpi.c sys/dev/bluetooth/bcsp.c sys/kern/vfs_bio.c sys/miscfs/syncfs/sync_subr.c and setting AcpiGbl_EnableAmlDebugObject. (mostly passing the address of a uint64_t when typed as CTLTYPE_INT). I've test built quite a few kernels, but there may be some unfixed MD fallout. Most likely passing &char[] to char *. Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.
