aaa48a8d25 Use USPACE_ALIGN for an alignment argument on allocating U-area. 
The default value is 0, and could be overridden by machine/vmparam.h.

f495cd9dc6 Introduce 2 new flags in types.h: 
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

405b695086 Make sobind() take a struct proc *. It already took curproc and 
passed it down to the appropriate usrreq function, and this
allows usage for contexts that need to be explicitly different
from curproc (like in the NFS code when binding to a reserved port).

66610a4779 Introduce PROC_PC(), which is used to get a process's user PC. If this is 
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.

ce866cd0e8 Don't hold a pool cache lock across any call to pool_get() or pool_put(). 
This allows us to change a try-lock into a normal lock in the reclaim
case.

7553470722 This is a first-cut implementation of support for caching of 
constructed objects in the pool allocator, similar to caching
of constructed objects in the Solaris SLAB allocator.

This implementation is a separate API (pool_cache_*()) layered
on top of pools to keep the caching complexity out of the way
of pools that won't benefit from it.

While we're here, allow pool items to be as large as the pool
page size.

*_emul_path variables

to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable: 
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

  done, right before machine-dependant switch to new context; also called
  for "old" emulation from sys_execve() if emulation of executed program and

23c15f1578 Don't set P_SUGID if the calls to set{e,}{u,g}id(), setreuid(), 
setgroups() did not result in actual changes. This has the nice
side effect that we don't needlesly allocate new credential and
resource limit data structures.

This is so that non setuid programs that call seteuid(getuid()),
don't end up setting P_SUGID, resulting in broken behavior [i.e.
non setuid ssh, doesn't read ~/.hostaliases...].

This is a good candidate for a pullup, if someone reviews it.
