ab4272e09e Prevent a mapped root which appears on the server as e.g. nobody from 
accessing files which it shouldn't be able to.  This required a better
approximation of VOP_ACCESS for NFSv2 (NFSv3 already has an ACCESS rpc
which is a better solution) and adding a call to VOP_ACCESS from VOP_LOOKUP.

a38455ecc1 Implementation of posix-style clock_* and nanosleep syscalls as implemented 
in NetBSD.  The core of settimeofday() is moved to a seperate static
function settime() which both clock_settime() and settimeofday() call.

Note that I picked up the securelevel > 1 check from NetBSD that prevents
the clock being set backwards in high securelevel mode (this was a hole
that allowed resetting of inode access timestamps to arbitary values)

Obtained from:  mostly from NetBSD, but the settime() function is from
our gettimeofday(), some tweaks by me.

1f075493b1 Don't allow access to illegal addresses in /dev/kmem to panic kernel 
(eg: above 0xffc00000).  Programs using /dev/kmem are implicitly racing
the kernel, and can get right up high in memory.  I've been running
these for some time now, but with printfs.  It's saved two panics at
least that I can remember.

27b2936ad3 clean up forked child creation. This is simplified also by having 
md_regs being struct trapframe *.  Do a npxsave() if needed and copy the
pcb rather than use the increasingly defunct savectx().  Copy %edi and
%ebp explicitly.

Submitted by: bde

XXX npxproc could be declared in npx.h so the externs with smp fruit
are not needed.

2a925f6803 md_regs is struct trapframe * now, rather than int [] 
Remove TF_REGP() macro and use.  The original reason (address space
problems due to having UPAGES in mapped into user space) is gone.  It
looks cleaner without it.

a5c67c037d This is the kernel linker. To use it, you will first need to apply 
the patches in freefall:/home/dfr/ld.diffs to your ld sources and set
BINFORMAT to aoutkld when linking the kernel.

Library changes and userland utilities will appear in a later commit.

sc_bcopy(), which is generic_bcopy() in reality, there is no point in
retaining bcopyw() calls in the source code.
