we were passing in a void* representing the PCB of the parent thread.
Now we pass a pointer to the parent thread itself.
The prime reason for this change is to allow cpu_set_upcall() to copy
(parts of) the trapframe instead of having it done in MI code in each
caller of cpu_set_upcall(). Copying the trapframe cannot always be
done with a simply bcopy() or may not always be optimal that way. On
ia64 specifically the trapframe contains information that is specific
to an entry into the kernel and can only be used by the corresponding
exit from the kernel. A trapframe copied verbatim from another frame
is in most cases useless without some additional normalization.
Note that this change removes the assignment to td->td_frame in some
implementations of cpu_set_upcall(). The assignment is redundant.
A previous call to cpu_thread_setup() already did the exact same
assignment. An added benefit of removing the redundant assignment is
that we can now change td_pcb without nasty side-effects.
This change officially marks the ability on ia64 for 1:1 threading.

got fixed two weeks after the ia64 version was copied from the alpha
version (see rev 1.32 of sys/alpha/alpha/mem.c). As such, we were
missing the same continue as on alpha.
While here, add a default case for the device minor switch and do
some general style(9) cleanups.
WARNING: this file still has bugs. When reading from region 6 or
region 7, we don't validate the physical address. One can trivially
cause a machine check by trying to read from address 0xFFFFFFFFFFFFFFF0
or something that uses the unimplemented physical address bits.

Always route PCI interrupts on i386 UP machines. I was planning to enable
this for i386 anyways once SMP support is done. Having this enabled fixes
problems on many people's laptops.

'use entire disk'. Neither for ia64 while I'm here - it needs a MBR if
its going to use fdisk+disklabel. The ia64 case is mostly academic though
because you'd be creating two partitions (dos + freebsd) rather than
a single freebsd-only partition.
Attach to the component devices using GEOM semantics.
Create a GEOM provider instead of using disk_create()
Use the GEOM OAM api for configuration.
I saw approx ~1% speedup in througput and ~7% in latency in a
simple minded test of a two-disk striped device.
This file was repo-copied from src/sys/dev/ccd/ccd.c.
This is not yet linked into the build.
While a string is readable without a tool, an array is easier to process for
a monitoring application. This also prevents the extra hoops we need with
sbufs and locking.
Move the mtx_init() in en_attach() higher before the first failure point so
that we can unconditionally destroy it in en_destroy().
There are two bugs: in the s///g case, the substitution didn't occur
at the end of the line; in the s///N case, the code didn't count
forwards along the line properly. See the sg, s3, s4, and s5 tests
in src/tools/regression/usr.bin/sed/.

an application compiled -static with libthr would dump core in
malloc(3) because the stub thread initialization routine in libc would
be used instead of the libthr supplied one.
don't allow it at the moment, the correct thing to do is try again.
Otherwise, libthr would fail this test because it doesn't allow
an unlimited number of concurrent threads per application.
doing make readmes if /tmp/.skip_ports exists. This file is created
after a complete run, which avoids that we do the lengthy operation
again for a rerelease.
When NOPORTS or NOPORTREADMES are defined, we create the file prior
to starting the release.
VOP_GETEXTATTR() to retrieve the attribute name list on some file
systems, and note that this will be replaced with its own VOP
in due course.

that the old API (passing "" as the attribute name to the _get_
interface) is now deprecated (and was probably a bad idea).

extattr_list_link() system calls, which return a least of extended
attributes defined for a vnode referenced by a file descriptor
or path name. Currently, we just invoke VOP_GETEXTATTR() since
it will convert a request for an empty name into a query for a
name list, which was the old (more hackish) API. At some point
in the near future, we'll push the distinction between get and
list down to the vnode operation layer, but this provides access
to the new API for applications in the short term.
