da6b22afaf - Rename the constant for the Master Data Parity Error flag in the
PCI status register to map its current name.
- Use PCIM_* rather than PCIR_* for constants for fields in various AER
  registers.  I got about half of them right in the previous commit.

4351ba272c Add drain functionality to sbufs. The drain is a function that is
called when the sbuf internal buffer is filled.  For kernel sbufs with a
drain, the internal buffer will never be expanded.  For userland sbufs
with a drain, the internal buffer may still be expanded by
sbuf_[v]printf(3).

Sbufs now have three basic uses:
1) static string manipulation.  Overflow is marked.
2) dynamic string manipulation.  Overflow triggers string growth.
3) drained string manipulation.  Overflow triggers draining.

In all cases the manipulation is 'safe' in that overflow is detected and
managed.

01f6f5fcd4 Refactor sbuf code so that most uses of sbuf_extend() are in a new
sbuf_put_byte().  This makes it easier to add drain functionality when a
buffer would overflow as there are fewer code points.

42768fec0f On architectures with non-tree-based page tables like PowerPC, every page
in a range must be checked when calling pmap_remove(). Calling
pmap_remove() from vm_pageout_map_deactivate_pages() with the entire range
of the map could result in attempting to demap an extraordinary number
of pages (> 10^15), so iterate through each map entry and unmap each of
them individually.

c14e163ad1 Fix a problem where device detection would work unreliably on Serverworks
K2 SATA controllers. The chip's status register must be read first, and
as a long, for other registers to be correctly updated after a command, and
this includes the command sequence in device detection as well as the
previously handled case after interrupts. While here, clean up some
previous hacks related to this controller.

37c380fbb5 Don't clobber an existing target object file when doing the DTrace
linking process. This is needed because we change the source object
files and the second this dtrace -G is run, no probes will be found.
This hack allows us to build postgres with DTrace probes enabled. I'll
try to find a way to fix this without needing this hack.

8f8ae306c6 nlge (alternate XLR GMAC driver) updates:
- 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.

670a090971 Clean up fast message ring code for XLR.
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.

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.
