files to use 5.x syntax (I hope..)
Note: I suppose one might need to hack the hints file as well?

Forgot to mention: creation of a full-fleged package archive requires some
changes in bsd.ports.mk, because currently it doesn't install some files
that are usually packed into the package archive (+MTREE_DIRS, +DISPLAY
and so on). Support for this will be committed later.
allows for an easy way to backup old version of port prior to installing
a new one;
- silence compiler warnings by killing some unused variables and adding
all includes necessary.

because the IN_RENAME flag only fixes a few of the huge number of race
conditions that can result in the source path becoming invalid even
prior to the VOP_RENAME() call. The panics created a serious security
issue whereby an attacker could fairly easily cause the panic to
occur, crashing the machine.
The correct solution requires a great deal of work in the namei
path cache code.

Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".
the target process was being held locked during the uiomove() call. If the
process calling readdir() was the same as the target process (for instance
'ls /proc/curproc/'), and uiomove() caused a page fault, the result would
be a proc lock recursion. I have no idea how long this has been broken -
possibly ever since pfind() was changed to lock the process it returns.
Also replace the one and only call to procfs_findtextvp() with a direct
test of td->td_proc->p_textvp.
appropriate cache flush that provides MEMORY_BARRIER in between handoffs
between host && RISC processor for the shared memory request/response
queues.

confused. Since sa_sigaction and sa_handler alias each other in a
union, the bug was completely harmless. This had been fixed as part
of the SIGCHLD changes in revision 1.125, but it was reverted when
they were backed out in revision 1.126.
- Flesh out ofw_readin routine.
- Add OpenFirmware load and exec routines.
- Make sure memory allocation for the kernel is done correctly.
- Change the way the heap is allocated so as to make it easier to deallocate
when we hand over.
- Add a command to print memory maps similar to the one for ia64.
With this patch, I can now load and hand over to a kernel on my iMac. There
are some problems with OpenFirmware routines failing after the hand over that
still need to be addressed.
The type of bus_space_tag_t is now a pointer to bus_space_tag structure,
and the bus_space_tag structure saves pointers to functions for direct
access and relocate access.
Added bsh_bam member to the bus_space_handle structure, it saves access
method either direct access or relocate access which is called by
bus_space_* functions.
Added the mecia device support. If the bs_da and bs_ra in bus tag are set
NEPC_io_space_tag and NEPC_mem_space_tag respectively, new bus_space stuff
changes the register of mecia automatically for 16bit access.

'regression.*'.
o Add 'regression.securelevel_nonmonotonic', conditional on 'options
REGRESSION', which allows the securelevel to be lowered for the purposes
of efficient regression testing of securelevel policy decisions.
Regression tests for securelevels will be committed shortly.
NOTE: 'options REGRESSION' should never be used on production machines, as
it permits violation of system invariants so as to improve the ability to
effectively test edge cases, and improve testing efficiency.
