- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

MFprojects/camlock r248982: Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph". If at some point we need some real XPT periphs (alike to pmpX now), quite likely they will be per-bus, and not a single global instance as xpt_periph now.

Clear freeze bit before calling xpt_release_devq.
This ensures that any ccbs which immediately start during the call to xpt_release_devq see an accurate picture of the frozen_lun_mask.

Wait until completion context unwinds before retrying CCBs that have been queued internally. This works around issue in the isci HAL where it cannot accept new I/O to a device after a resetting->ready state transition until the completion context has unwound.
This issue was found by submitting non-tagged CCBs through pass(4) interface to a SATA disk with an extremely small timeout value (5ms). This would trigger internal resets with I/O in the isci(4) internal queues.
The small timeout value had not been intentional (and original reporter has since changed his test to use 5sec instead), but it did uncover this corner case that would result in a hung disk.

Queue CCBs internally instead of using CAM_REQUEUE_REQ status. This fixes problem where userspace apps such as smartctl fail due to CAM_REQUEUE_REQ status getting returned when tagged commands are outstanding when smartctl sends its I/O using the pass(4) interface.

Call xpt_bus_register during attach context, then freeze and do not release until domain discovery is complete. This fixes an isci(4) bug on FreeBSD 7.x where devices weren't always appearing after boot without an explicit rescan.

Remove explicit CC assignment in isci(4) Makefile to allow for building with clang. Also fix a number of warnings uncovered when building with clang around some implicit enum conversions.

Add isci(4) driver for amd64 and i386 targets.
The isci driver is for the integrated SAS controller in the Intel C600 (Patsburg) chipset. Source files in sys/dev/isci directory are FreeBSD-specific, and sys/dev/isci/scil subdirectory contains an OS-agnostic library (SCIL) published by Intel to control the SAS controller. This library is used primarily as-is in this driver, with some post-processing to better integrate into the kernel build environment.
isci.4 and a README in the sys/dev/isci directory contain a few additional details.
This driver is only built for amd64 and i386 targets.
