on a process's pending signals, use the signal queue flattener,
ksiginfo_to_sigset_t, on the process, and on a local sigset_t, and then work
with that as needed.
of 1 so that it is not probed until after acpi0 is probed and attached.
- In legacy_probe(), return ENXIO if acpi0 is around and alive.
- nexus_attach() is now much simpler and just lets its child drivers do
all the work.
and attach routines have succeeded so that if they fail we can still use
the PnP BIOS to find ISA on-board devices. The fact that we do this here
is gross but fixing it properly involves a lot more work.
testing any modifications to them, they shouldn't even bother with
disklabels in the first place and they are just plain obsolete old
hardware which should be axed entirely before 5.0-R IMO.

- 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.
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.
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.
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.
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.
