o Make mmc_get_bits a little clearer... It really only works on 128-bit

reduce ABI disruptions when new cpu types and new PMC events are added
in the future.
- Support alternate spellings for PMC events. Derive the canonical
spelling of an event name from its enumeration name in 'enum pmc_event'.
- Provide a way for users to disambiguate between identically named events
supported by multiple classes of PMCs in a CPU.
- Change libpmc's machine-dependent event specifier parsing code to
better support CPUs containing two or more classes of PMC resources.
If you just config KERNEL as usual there should be no apparent changes, you'll get all chipset support code compiled in.
However there is now a way to only compile in code for chipsets needed on a pr vendor basis. ATA now has the following "device" entries:
atacore: ATA core functionality, always needed for any ATA setup
atacard: CARDBUS support
atacbus: PC98 cbus support
ataisa: ISA bus support
atapci: PCI bus support only generic chipset support.
ataahci: AHCI support, also pulled in by some vendor modules.
ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, atamarvell, atamicron, atanational, atanetcell, atanvidia, atapromise, ataserverworks, atasiliconimage, atasis, atavia; Vendor support, ie atavia for VIA chipsets
atadisk: ATA disk driver
ataraid: ATA softraid driver
atapicd: ATAPI cd/dvd driver
atapifd: ATAPI floppy/flashdisk driver
atapist: ATAPI tape driver
atausb: ATA<>USB bridge
atapicam: ATA<>CAM bridge
This makes it possible to config a kernel with just VIA chipset support by having the following ATA lines in the kernel config file:
device atacore
device atapci
device atavia
And then you need the atadisk, atapicd etc lines in there just as usual.
If you use ATA as modules loaded at boot there is few changes except the rename of the "ata" module to "atacore", things looks just as usual.
However under atapci you now have a whole bunch of vendor specific drivers, that you can kldload individually depending on you needs. Drivers have the same names as used in the kernel config explained above.

Use mbuf tagging for accounted packets to not account packets twice when
both ingress and egress netflow enabled.
To keep compatibility new "setconfig" message added to control new

accounting without using mbuf tags.

Add UNIX domain socket support to udpzerobyte, which suggests this
regression test should be moved to the general sockets test area rather
than netinet.
no data is ready, return 0 rather than blocking or returning EAGAIN.
This is consistent with the behavior of soreceive_generic (soreceive)
in earlier versions of FreeBSD, and restores this behavior for UDP.

netisr or ithread's socket buffer size limit is not the right limit to
use. Instead, pass NULL as the other two calls to sbreserve_locked()
in the TCP input path (tcp_mss()) do.
In practice, this is a no-op, as ithreads and the netisr run without a
process limit on socket buffer use, and a NULL thread pointer leads to
not using the process's limit, if any. However, if tcp_input() is
called in other contexts that do have limits, this may prevent the
incorrect limit from being used.
