required by video card drivers. Specifically, this change introduces
vm_cache_mode_t with an appropriate VM_CACHE_DEFAULT definition on all
architectures. In addition, this changes adds a vm_cache_mode_t parameter
to kmem_alloc_contig() and vm_phys_alloc_contig(). These will be the
interfaces for allocating mapped kernel memory and physical memory,
respectively, with non-default cache modes.

allow them to start after netif. There were too many problems reported
with this change in the short period of time that it lived in HEAD, and
we are too late in the release cycle to properly shake it out.
IMO the issue of having the firewalls up before the network is still a
valid concern, particularly for pf whose default state is wide open.
However properly solving this issue is going to take some investment
on the part of the people who actually use those tools.
This is not a strict reversion of all the changes for r193198 since it
also included some simplification of the BEFORE/REQUIRE logic which is
still valid for ipfilter and ip6fw.
if_addr_rlock() and if_addr_runlock() for regular address lists, and
if_maddr_rlock() and if_maddr_runlock() for multicast address lists.
We will use these in various kernel modules to avoid encoding specific
type and locking strategy information into modules that currently use
IF_ADDR_LOCK() and IF_ADDR_UNLOCK() directly.

arrays to [MAXCPU], offering moderate memory savings. In some places,
this requires using CPU_ABSENT() to handle less common platforms with
sparse CPU IDs. In several places, assert that the selected CPUID for
work placement or statistics is not CPU_ABSENT() to be on the safe side.

vfs.ufs.dirhash_maxmem below the current amount of memory used by dirhash. When
ufsdirhash_build() is called with the memory in use greater than dirhash_maxmem,
it attempts to free up memory by calling ufsdirhash_recycle(). If successful in
freeing enough memory, ufsdirhash_recycle() leaves the dirhash list locked. But
at this point in ufsdirhash_build(), the list is not explicitly unlocked after
the call(s) to ufsdirhash_recycle(). When we next attempt to lock the dirhash
list, we will get a "panic: _mtx_lock_sleep: recursed on non-recursive mutex
dirhash list".

d_mmap_single(). I considered adding a new round of padding for 8.0.
However, since cdevsw already maintains a version field, new versions
can be handled without requiring the need for explicit padding fields.
Specifically, if a non-root user attempts to bind an interrupt the request
will now report failure with EPERM rather than silently failing with a
successful return code.

This is mostly important for the multiple MSI message case where the
IDT vectors for the entire group need to be allocated together. This
also restores the assumptions made by the PCI bus code that it could
invoke PCIB_MAP_MSI() once MSI vectors were allocated.
- To avoid whiplash with CPU assignments, change the way that CPUs are
assigned to interrupt sources on activation. Instead of assigning the
CPU via pic_assign_cpu() before calling enable_intr(), allow the
different interrupt source drivers to ask the MD interrupt code which
CPU to use when they allocate an IDT vector. I/O APIC interrupt pins
do this in their pic_enable_intr() routines giving the same behavior as
before. MSI sources do it when the IDT vectors are allocated during
msi_alloc() and msix_alloc().
- Change the intr_table_lock from an sx lock to a mutex.
