(a/k/a fsync(2)), System V style message queues, semaphores and shared memory
at runtime by adding a sysctl variable for each.

b2c24dbcbe Add an if_drain to the ifnet structure (call when the system is low 
on mbufs).  Add code to m_reclaim to call if_drain in each ifnet
that has one set.  Remove register from declarations.

d0e85dde99 Inline vref/vrele in vclean() because: 
* we already have the vnode interlock, so vref() should not ask for it again.
* we call VOP_RECLAIM/VOP_INACTIVE(), which shouldn't be duplicated in vrele().

82eb51ee05 In soshutdown(), decouple the evaluation of the `how' argument from FREAD 
and FWRITE; use SHUT_{RD,WR,RDWR} instead.
Also, return EINVAL if `how' is invalid.

7a239c12c6 In vfs_unmountall(), if curproc is NULL, abort, because unmounting 
puts the requesting process to sleep until the file systems buffers
have flushed, and sleeping with a NULL curproc will cause a fault.

2018d40811 Allocate kernel virtual address space for the U-area before allocating 
the new proc structure when performing a fork.  This makes it much
easier to abort a fork operation and return an error if we run out
of KVA space.

The U-area pages are still wired down in {,u}vm_fork(), as before.

3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of 
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

b436157e65 Make proc0 use the statically-allocate vmspace0 again, and make it use 
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.

This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.

clarification to a comment.
