MFC: /- and my license changes for sys/[a-d]

* Add a "how" argument to uma_zone constructors and initialization functions

2004-08-02T00:18:36+00:00

  so that they know whether the allocation is supposed to be able to sleep
  or not.
* Allow uma_zone constructors and initialation functions to return either
  success or error.  Almost all of the ones in the tree currently return
  success unconditionally, but mbuf is a notable exception: the packet
  zone constructor wants to be able to fail if it cannot suballocate an
  mbuf cluster, and the mbuf allocators want to be able to fail in general
  in a MAC kernel if the MAC mbuf initializer fails.  This fixes the
  panics people are seeing when they run out of memory for mbuf clusters.
* Allow debug.nosleepwithlocks on WITNESS to be disabled, without changing
  the default.

Both bmilekic and jeff have reviewed the changes made to make failable
zone allocations work.

Update for the KDB framework:

2004-07-10T21:03:52+00:00

o  Call kdb_enter() instead of Debugger().
o  Don't make such calls conditional upon KDB instead of DDB because
   they're already conditional upon EN_DEBUG.

Add missing includes

2004-05-30T20:08:47+00:00

Convert callers to the new bus_alloc_resource_any(9) API.

All three of these drivers abused cv_waitq_empty in the same way by spinning

2004-02-29T09:26:01+00:00

on it in hopes of making sure that the waitq was empty before going on.
This wasn't needed and probably never would have worked as intended.  Now
that cv_waitq_empty() and friends are gone, the code in these drivers that
spins on it can go away too.  This should unbreak LINT.

Move the locking of the softc up to before the allocation of the

2003-12-17T10:01:46+00:00

transmission map. This allocation accesses the softc so should
be under the lock (it uses NOWAIT).

Replace the if_name and if_unit members of struct ifnet with new members

2003-10-31T18:32:15+00:00

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

Use __FBSDID().

Also some minor style cleanups.

Prefer new location of pci include files (which have only been in the

2003-08-22T05:54:52+00:00

tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.
