_bus_dmamem_unmap():
...
Sets the specified pages cacheable again because _bus_dmamem_map() might
change them uncacheable.
The code was provided by Dhoyashiki-san in kern/19919.

Rearrange the trapframe and mcontext to put the registers used for

argument passing to be in front, in order. Define constants for
offsets inside frames, to avoid having to redo asm code should they
change again.

Remove right duplication on thread creation, which became useless now we

are using lwp.
Enable kill -9 to kill parent thread waiting for its child.
Use upcallret instead of child_return for the newly created lwp.
Add debug messages for thread creation.
Thread creation are still broken...

Bump daddr_t to 64 bits. Replace it with int32_t in all places where

it was used on-disk, so that on-disk formats remain the same.

use %e?x instead of %?x as 'xorl' arguments

use %al for 'movb' target, and 'andb' for masking the result with $0x02

Optimize xcall() et.al. further by maintaining a cpuset mask of all CPUs
...
marked ready. This saves repeated testing for NULL pointers and the
CPUFLG_READY flag.
Also use a separate flag variable to signal xcall completion. This saves a
load and a pipeline stall.
