9d157a1ecb Add assembler version of in_cksum. Thanks to ad@ for his time as 
peep hole optimiser. This is 30% faster than the portable C version
for checksumming 64byte and larger mbufs and as fast as or slightly
faster for shorter mbufs (with a high variance).

ba7a604397 Reorder the amd64 trapframe (swap rcx/r10 and add 4 spare slots after r9). 
This allows the syscall code to pass the syscall args directly from the
trapframe instead of copying them to a separate structure.
It is still possible that some lurking code still assumes that
'struct trapframe', 'struct mcontext' and 'struct reg' all have the
registers in the same order, but I've fixed enough of them to get gdb working.

77fe68004d Do not assume that 'struct reg' and 'struct trapframe' have the same

abceae9908 Change the way that the trap/intr/syscall frames and the __gregset_t[] 
indexes are defined so that only a single list of the registers is used.
The code no longer relies on the two structures matching.
There should be no binary change.

1dd75d2865 Add a simple in-kernel linker, derived from FreeBSD's link_elf_obj.c. Needs 
more work but is enough to load simple LKMs. amd64 is untested.

Locking is caller provided. This is decoupled from the LKM framework because
kernel modules need not be loaded from the file system - they could be built
into the kernel and referenced via link set.

14780346b4 Remove this; objections from joerg@ and ad@, and I agree with them that 
additional kernel configs are not the way to go because they are not
flexible at all.  Plus ad@ is working on a real solution (bootprop).

2b35d82f32 Add PHYSMEM_MAX_ADDR and PHYSMEM_MAX_SIZE options. This limit physical 
memory based on overall size (useful for debugging to keep core dumps
small) or maximum address (when using devices with bus dma limits).
Contrary to REALBASEMEM and REALEXTMEM, they still use the BIOS memory
map and can therefore deal with fragmented memory.

2cbcb46f49 - share idt entry allocation code among x86.

a1e817b5ba Define 'struct intrframe' in terms of 'struct trapframe' since the two are 
assumed to match by a lot of code (including that which saves the regs).
This only slightly reduces the number of places the trapframe register
layout is defined.

89a3551a18 Create the trap/syscall frame space for all the registers in one go. 
Use the tramp-frame offsets (TF_foo) for all references to the registers.
Sort the saving of the GP registers into the same order as the trap frame
because consequetive memory accesses are liekly to be faster.
