37c841831f Be consistent about "static" functions: if the function is marked
static in its prototype, mark it static at the definition too.

58eab4797a Update the nexus driver for the addition of the legacy driver:
- nexus no longer has PCI bridges as direct children, so the PCI bus
  ivar is no longer used and is removed.
- Don't attach default EISA, ISA, or MCA busses.  Instead, if we do not
  have an acpi0 device after bus_generic_probe(), add a legacy0 child
  device.
- Remove machine/nexusvar.h.

e8e951ce31 Add a new legacy(4) device driver for use on machines that do not have
ACPI or for when ACPI support is disabled or not present in the kernel.
Basically, the nexus device is now split into two with some parts
(such as adding default ISA, MCA, and EISA busses if they aren't found
as well as support for PCI bus device ivars) being moved to the legacy
driver.

c692fbe091 At great personal risk, add a __packed and __aligned(x) define that
expand to __attribute__((packed)) and __attribute__((aligned(x)))
respectively.  Replace the handful of gcc-ism's that use
__attribute__((aligned(16))) etc around the kernel with __aligned(16).

There are over 400 __attribute__((packed)) to deal with, that can come
later.  I just want to use __packed in new code rather than add more
gcc-ism's.

abc370fa85 Moved nfs_diskless setup code from autoconf.c to nfsclient/nfs_diskless.c
so that it is MI.  Allow nfs_mountroot to return an error if the nfs_diskless
struct is not valid, rather than panicing later on.  Call nfs_setup_diskless()
from nfs_mountroot if NFS_ROOT is defined, like bootpc_init().  Removed legacy
root mount support for sparc64, and enabled NFS_ROOT by default.

05ba50f522 Use the fields in the sysentvec and in the vm map header in place of the
constants VM_MIN_ADDRESS, VM_MAXUSER_ADDRESS, USRSTACK and PS_STRINGS.
This is mainly so that they can be variable even for the native abi, based
on different machine types.  Get stack protections from the sysentvec too.
This makes it trivial to map the stack non-executable for certain abis, on
machines that support it.

6fb3d70418 For reasons now lost in historical fog, the bounds_check_with_label()
function were put in i386/i386/machdep.c from where it has been
cut and pasted to other architectures with only minor corruption.

Disklabel is really a MI format in many ways, at least it certainly
is when you operate on struct disklabel.

Put bounds_check_with_label() back in subr_disklabel.c where it belongs.

c79408a059 Implement db_print_backtrace() if DDB is compiled into the kernel. This
MD function is just a wrapper around db_stack_trace_cmd() that prints out
a backtrace of curthread.  Currently, this function is only implemented
on i386 and alpha (and the alpha version isn't quite tested yet, will do
that in a bit).  Other changes:

- For i386, fix a bug in the raw frame address case.  The eip we extract
  from the passed in frame address does not match the frame we received.
  Thus, instead of printing a bogus frame with the wrong eip, go ahead
  and advance frame down to the same frame as the eip we are using.
- For alpha, attempt to add a way of doing a raw trace for alpha.  Instead
  of passing a frame address in 'addr', pass in a pointer to a structure
  containing PC and KSP and use those to start the backtrace.  The alpha
  db_print_backtrace() uses asm to read in the current PC and KSP values
  into such a request.

37ee08bcab From Christian Zander:
This patch addresses a bug that can cause a GPF in the kernel - if a
process makes use of i386_set_ldt to install a LDT entry, then loads
a corresponding segment descriptor into %gs, forks, and if the child
execs.

In this scenario, setregs executes user_ldt_free and then determines
how to reset the %gs register:

    /* reset %gs as well */
    if (pcb == curpcb)
        load_gs(_udatasel);
    else
        pcb->pcb_gs = _udatasel;

This is insufficient in the fork/exec case, since pcb will be equal
to curpcb when the child execs; load_gs will reset %gs to _udatasel
but it doesn't reset pcb->pcb_gs; upon return from the system call,
cpu_switch_load_gs will thus attempt to restore %gs from pcb->pcb_gs
and trigger a GPF since all LDT entries have already been cleared.

The fix is to always reset pcb->pcb_gs to _udatasel.
