Presently there is no way for mtx_assert to determine that we're not executing in a real thread context.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

It is a pretty hard to come up with even a theoretical concept of a device driver which would always fail open and close with ENODEV. Change the defaults to be nullopen() and nullclose() which simply does nothing. Remove explicit initializations to these from the drivers which already used them. It is not an error to have no devices in the kernel: Return the 2003-08-17T12:06:19Z Poul-Henning Kamp phk@FreeBSD.org 2003-08-17T12:06:19Z urn:sha1:037c3d0fb035be10ead8afeed05d6d90fd46021e generation number and start it from one instead of zero.

This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long. Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.
