- Updates for the message ring clean up in r212321.
- Instead of dropping Tx packet on credit fail, retry send until it
succeeds.
- Fix freeing mbufs in case of P2P descriptors:
We cannot free the mbuf when the P2P descriptor freeback is received. The
mbuf may be still in use by the GMAC, since the P2P freeback indicates that
it read the P2D descriptors in the P2P message.
Now we free just the P2P descriptor when the P2P freeback message is
received. Another freeback P2D message has been added to the end of
the packet descriptors, the mbuf will be freed only when we received
this.
The P2P descriptor issue was reported by srgorti at netlogicmicro dot com.

and may cause timer not being reloaded. Check such cases on interrupt
arival and reload timer to give system some more time to manage proper
binding.
wrong element of the VSID bitmap array to be examined after a collision,

Fix message ring send path:
- define msgrng_access_enable() which disables local interrupts
and enables message ring access. Also define msgrng_restore() which
restores interrupts
- remove all other msgrng enable/disable macros, no need of critical_enter
and other locking here.
- message_send() fixup: re-read status until pending bit clears
- message_send_retry() fixup: retry only few times with interrupts disabled
- Fix up message_send/message_send_retry callers - call
msgrng_access_enable() and msgrng_restore() correctly so that interrupts
are not disabled for long.
- removed unused and obsolete code from sys/mips/rmi/msgring.h
- some style fixes - more later
rge.c (XLR GMAC driver):
- updated for the message ring changes
- remove unused message_send_block()
- retry on credit failure, this is not a permanent failure when credits
are configured correctly. Add panic if credits are not available to
send for a long time.

"uncore" devices (such as the memory controller) in that socket. Stop
hardcoding support for two busses, but instead start probing buses at
domain 0, bus 255 and walk down until a bus probe fails. Also, do not probe
a bus if it has already been enumerated elsewhere (e.g. if ACPI ever
enumerates these buses in the future).
Because FreeBSD no longer supports the 80386 cpu all code targeting
FreeBSD/i386 necessarily runs on i486 or higher so the compiler
built-ins can be used by default inside libstdc++ and in C++ headers.
This allows newly compiled C++ code to inline some atomic operations.
Old binaries continue to use libstdc++ functions.

Fix interrupt routing so that the irq returned is correct for XLR and
XLS. This also updates the MSI hack we had earlier - we still don't
really support MSI, but we support some drivers that use MSI, by providing
support for allocating one MSI per pci link - this MSI is directly
mapped to the link IRQ.
lock on the pmc-sx lock. This prevents a deadlock with
pmc_log_process_mappings, which has an exclusive lock on pmc-sx and tries
to get a read lock on a vm_map. Downgrading the vm_map_lock in munmap
allows pmc_log_process_mappings to continue, preventing the deadlock.
Without this change I could cause a deadlock on a multicore 8.1-RELEASE
system by having one thread constantly mmap'ing and then munmap'ing a
PROT_EXEC mapping in a loop while I repeatedly invoked and stopped pmcstat
in system-wide sampling mode.

Octal escape sequences are expanded to bytes, not characters, and multiple
are required for a multibyte character.
The valid escape sequences in %b strings are slightly different from the
escape sequences in the format string.
