install directly into standard POWER LPARs, as found for example in
QEMU. The core of this device is the SCSI RDMA protocol as also found in
Infiniband. The SRP portions of the driver will be factored out and placed
/sys/cam in the future to allow them to be used for IB storage. Thanks to
Scott Long for a great deal of implementation help.

CAM_EXTLUN_VALID is not erroneously set. Also add an XPORT_SRP
identifier to the known SCSI transports for the SCSI RDMA protocol, as
used, for example with Infiniband storage.

platform modules. Whether to call this function or not is highly machine
dependent: on some systems, it is required, while on others it breaks
everything. Platform modules are in a better position to figure this
out. This is required for POWER hypervisor SCSI to work correctly. There
are no functional changes on Powermac systems.

approach, which is taken from Linux, is to scan through the PCI bars
until we find one large enough to contain the linear framebuffer and
which is ideally prefetchable if no "address" property can be found.
This makes the graphical console work with the pSeries target in QEMU.

Without these, if the timeout value passed is "large enough", the
value of the sum of it and other factors (e.g. current time as
returned by sbinuptime() or 'precision' argument) might result in a
negative number. This negative number is then passed to
eventtimers(4), which causes et_start() routine to load et_min_period
into eventtimer, making the CPU where the thread is stuck forever in
timer interrupt handler routine. This is now avoided rounding to
INT64_MAX the timeout period in case of overflow.

binary is built for as arm and armv6 have slight differences meaning only
some binaries build for one will work as expected on the other. It is
expected pkgng will be able to make use of this to simplify the logic to
determine which package ABI to use.

- Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0;
MPSAFE drivers should be managing their own timeout storage. The
remaining non-MPSAFE drivers have been modified to also manage their own
storage, and should be considered for updating to MPSAFE (or removal)
during the FreeBSD 10.x lifecycle.
- Add fields related to soft timeouts and quality of service, to be used
in upcoming work.
- Add room for more flags in the CCB header and path_inq structures.
- Begin support for extended 64-bit LUNs.
- Bump the CAM version number to 0x18, but add compat shims. Tested with
camcontrol and smartctl.
