to amd64, i386, and pc98. The headers are installed to /usr/include/x86
during an installworld, and an 'x86' symlink is created for kernel builds
similar to 'machine' so that the headers can be included as <x86/foo.h>.

about but otherwise ignored. When allowing the master to be set manually via
ifconfig(8) by adding the former to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS
(as it should be) it seems to be unfavorable that a machine can be made to
panic with a simple ifconfig(8) invocation.
concurrency bug. Since all SLB/SR entries were invalidated during an
exception, a decrementer exception could cause the user segment to be
invalidated during a copyin()/copyout() without a thread switch that
would cause it to be restored from the PCB, potentially causing the
operation to continue on invalid memory. This is now handled by explicit
restoration of segment 12 from the PCB on 32-bit systems and a check in
the Data Segment Exception handler on 64-bit.
While here, cause copyin()/copyout() to check whether the requested
user segment is already installed, saving some pipeline flushes, and
fix the synchronization primitives around the mtsr and slbmte
instructions to prevent accessing stale segments.

not able to trigger the issue with sample boards, some users seems
to suffer from freeze/lockup when system is booted without UTP cable
plugged in. I'm not sure whether this is BIOS issue or controller
bug. This change fixes AR8132 lockup issue seen on EEE PC.

was incorrect as further down the road cons_probe() calls malloc() so the
former can't be called before init_heap() has succeed. Instead just exit
to the firmware in case init_heap() fails like OF_init() does when hitting
a problem as we're then likely running in a very broken environment where
hardly anything can be trusted to work.
- Rename RES_BUS_SPACE_* into BUS_SPACE_* for consistency
- Trim out an unnecessary checking condition

In xbb_detach() only perform cleanup of our taskqueue and

This avoids a panic when xbb_detach() is called on a partially

the dual port BCM5717 and BCM5718 devices which are intended for
mainstream workstation and entry-level server designs and
represents the twelfth generation of NetXtreme Ethernet controllers.
This family is the successor to the BCM5714/BCM5715 family and
supports IPv4/IPv6 checksum offloading, TSO, VLAN hardware tagging,
jumbo frames, MSI/MSIX, IOV, RSS and TSS.
This change set supports all hardware features except IOV and
RSS/TSS. Unlike its predecessors, only extended RX buffer
descriptors can be posted to the jumbo producer ring. Single RX
buffer descriptors for jumbo frame are not supported. RSS requires
a more substantial set of changes and will apply to a larger set
of NetXtreme devices so RSS/TSS multi-queue support will be
implemented in a future releases.
Special thanks to Broadcom who kindly sent a sample board to me
and to davidch who gave provided the initial support code.

physical page mapping should span two or more MTRRs of different types.
Add a pmap function, pmap_demote_DMAP(), by which the MTRR module can
ensure that the direct map region doesn't have such a mapping.

[3] Re-enable the use of 1GB page mappings for implementing the direct
map. (See also r197580 and r213897.)
