b2aefec351 Remove pointless check against PID_MAX. Let pfind() do the validation. 
(The new pid allocation code may decide to allocate pids above PID_MAX.)

b327a5601a don't bother special-casing DTYPE_KQUEUE/DTYPE_MISC nor panic for unknown 
descriptors; just return with EOPNOTSUPP for any unsupported descriptor type

b1fc5ffac3 procfs_allocvp(): 
* do not set *vpp unless successful, otherwise we'd trigger
    DIAGNOSTIC panic in lookup(9) on error return
  * on error, make sure to free malloc'ed memory and ungetnewvnode() the
    previously acquired vnode

this fixes panic on 'tail -f <file> &; ls -l /proc/$!/fd' reported by
Andrew Brown

Shouldn't we introduce a PRIoff_t macro to create such format strings?

dbe6c38bc2 Implement /proc/<pid>/fd/<n>. This is work in progress. Questionable things: 
- Is it ok to convert DTYPE_PIPE to VFIFO and DTYPE_SOCKET to VSOCK?
    - XXX: Avoid locking issue in ls -Rl /proc by avoiding curproc
    - Does I/O to pipes work?
    - XXX: Are there security implications?

02eb342b57 Make sure that the pointer to old parent process for ptraced children 
gets reset properly when the old parent exits before the child. A flag
is set in old parent process when the child is reparented in ptrace(2).
If it's set when process is exiting, all running processes have their
'old parent process' pointer checked and reset if appropriate. Also
change to use 'struct proc *' pointer directly, rather than pid_t.
This fixes security/14444 by David Sainty.

03efee5585 * Allow machine-dependent code to specify hooks for ptrace(2) 
(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
  These changes will allow platforms like x86 (XMM) and PowerPC
  (AltiVec) to export extended register sets in a sane manner.

* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
  FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
  ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
  /proc/N/xmmregs in procfs.

adf5d360a7 add a new VFS op, vfs_reinit, which is called when desiredvnodes is 
adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

convert various file systems to use the <sys/queue.h> macros for
their hash tables.

	from `vm_minsaddr'.
