system super block after fsck has repaired the file system. The value of
fs_ronly was getting overwritten, which caused ffs_update() to attempt to
update inode timestamps even though the file system was still mounted
read-only.
This fixes the "giving up on N buffers" error that is triggered by running
fsck on the root file system and then rebooting without mounting the file
system read-write.

This driver hasn't compiled for 3 years since the PCI compat shims
were removed, and Lan Media appears to have gone out of business.
These cards appear to be rare (a recent search of ebay had no hits).
Should someone wish to revive this driver, submitting patches to make
it compile plus a testing report will bring it back.

The loran hardware was very unique, and only a few copies of it ever

contacted, he indicated that he had no intention of ever updating this
driver and it was no longer relevant to the FreeBSD world and can be
removed without impact to anybody.

and the mpo_create_cred() MAC policy entry point to
mpo_copy_cred_label(). This is more consistent with similar entry
points for creation and label copying, as mac_create_cred() was
called from crdup() as opposed to during process creation. For
a number of policies, this removes the requirement for special
handling when copying credential labels, and improves consistency.

between vm_map and vnode locks is that vm_map locks are acquired first. In
revision 1.150 mmap(2) was changed to pass a locked vnode into vm_mmap().
This creates a lock-order reversal when vm_mmap() calls one of the vm_map
routines that acquires a vm_map lock. The solution implemented herein is
to release the vnode lock in mmap() before calling vm_mmap() and reacquire
this lock if necessary in vm_mmap().

- Add a really, really, nasty hack to provide stub versions of all of
the 'device apic' functions used by the ACPI MADT APIC enumerator if
'device apic' is not compiled into the kernel. This is gross but is
the best we can do with the current kernel linker implementation.

APIC programming all at SI_SUB_CPU / SI_ORDER_FIRST. This is needed to
help get the ACPI module working again as it moves the APIC enumeration
code after SI_SUB_KLD.
- In the MADT parser, use mp_maxid rather than MAXCPU to terminate a loop
when assigning per-cpu ACPI IDs to avoid a dependency on 'options SMP'.
- Allow the apic device to be disabled via 'hint.apic.0.disabled' from the
loader. Note that since this is done in the local APIC code, it works
for both the ACPI and non-ACPI cases.

- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of
using a statically sized array that depended on 'options SMP'.
- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
disable C3 for SMP machines.

the acpi_cpu(4) driver, to work properly with both SMP and UP kernels.
The exported symbols include mp_ncpus, all_cpus, mp_maxid, smp_started, and
the smp_rendezvous() function. This also means that CPU_ABSENT() is now
always implemented the same on all kernels.
