Also disable relaxed ordering as recommended by data sheet for
PCI-X devices. For PCI-X BCM5704, set maximum outstanding split
transactions to 0 as indicated by data sheet.
For BCM5703 in PCI-X mode, DMA read watermark should be less than
or equal to maximum read byte count configuration. Enforce this
limitation in DMA read watermark configuration.
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.

objects used to provide per-thread storage in the RPC code. Almost all
of these used double-checking with a dedicated mutex (tsd_lock) to do this
before. However, that is not always safe with more relaxed memory orders.
There were also other bugs, such as one in __rpc_createrr() that caused a
new key to be allocated each time __rpc_createrr() was invoked.

chip revision often found in the blades and resulting in interfaces
not sensing carrier signal. Looking at all problem reports it
appears that it only affects some very specific silicon revision
(ASIC (0x57081021); Rev (B2)) and version of the PHY that
supports 1000baseSX-FDX media only. Therefore, narrow the scope of
workaround to combination of that revision and media type. Given
that the first report on this issue is dated back to 2007, there is
not much hope that this issue will ever be properly resolved.
Among affected systems are IBM HS21, Intel SBXD132 and HP BL460c.

These header files only provide functionality that can be used in
combination with libcompat. In order to prevent people from including
them without any actual use (which happens a lot with <sys/timeb.h>),
put a warning here to make people more aware.
This means we have to lower WARNS for libcompat, which is no big deal.

Setting the new sysctl MIB "debug.acpi.enable_debug_objects" to a non-zero
value enables us to print Debug object when something is written to it.

"debug.acpi.interpreter_slack" to zero disables some workarounds for common
BIOS mistakes and enables strict ACPI implementations by the specification.

under virtualization. Moreover, machine check exceptions can safely be
enabled when FreeBSD is running natively on Family 10h processors.
Most of the credit should go to Andriy Gapon for diagnosing the error and
working with Borislav Petkov at AMD to document it. Andriy also reviewed
and tested my patches.
