creating a trapframe, with exceptions disabled and using only BANK1

create a trapframe and proceed to the full-blown C handler."

vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization
when the function is inlined, and avoids accessing memory on architectures
when we can pass function arguments in registers.

will return the usual 0x100 bytes of PCI configuration space, but this will
eventually change on PCIe-capable controlers.

kernel, currently limited to low-hanging fruit: these variables were used
by bus_dma to specify the range in which to allocate memory, back when
uvm_pglistalloc() was stupid and would not walk the vm_physseg[].
Nowadays, except on some platforms for early initialization, these variables
are not used, or do not need to be global variables. Therefore:
- remove `extern' declarations of avail_start and avail_end (or close cousins,
such as arm physical_start and physical_end) from files which no longer need
to use them.
- make them local variables whenever possible.
- remove them when they are assigned to but no longer used.

max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new
situation. The larger buffers are required by the very high speed
KDDI devices in Japan (CF com, or USB ucom) so those are the only two
drivers which currently ask for a larger buffer size.

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and
remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).
Based on a diff from tedu.

long discussion with nicm, murmers of consent from tedu and miod, noone

stopped looking, so who knows what else was broken. A simple comparison of
the existing mtx_enter with the new mtx_enter_try would have told anybody.

MD code would free resources that couldn't be freed until we were no
