right for certain MAP_FIXED mappings on ia64 but it will work fine for all
other mappings and works fine on amd64.

- In kern_ndis.c:ndis_unload_driver(), test that ndis_block->nmb_rlist
is not NULL before trying to free() it.
- In subr_pe.c:pe_get_import_descriptor(), do a case-insensitive
match on the import module name. Most drivers I have encountered
link against "ntoskrnl.exe" but the ASIX USB ethernet driver I'm
testing with wants "NTOSKRNL.EXE."
- In subr_ntoskrnl.c:IoAllocateIrp(), return a pointer to the IRP
instead of NULL. (Stub code leftover.)
- Also in subr_ntoskrnl.c, add ExAllocatePoolWithTag() and ExFreePool()
to the function table list so they'll get exported to drivers properly.
after a return. Move assignments to {freePtr, dynamic, start} closer to the
return statements to clarify which variables are actually used for
communication between the losely coupled blocks of the code. Clear up
an if-expression to make common structures of the conditions clearer.
Use strchr instead of switch statements to check for a character beeing
a member of a set.

mastering on all other interfaces:
- call carp_carpdev_state() on initialize instead of just setting to INIT
- in carp_carpdev_state() check that interface is UP, instead of checking
that it is not DOWN, because a rebooted machine may have interface in
UNKNOWN state.

inputs. The trouble with replacing two floats with a double is that
the latter has 6 extra bits of precision, which actually hurts
accuracy in many cases. All of the constants are optimal when float
arithmetic is used, and would need to be recomputed to do this right.

object on to the zone allocator. It should be noted that uma_zalloc(9)
uses bzero to zero out the object so there probably wont be any
real performance benefit. If UMA grows the ability to supply
zeroed zones more efficiently in the future, we will not have to
modify all the existing consumers.
