1040a0007e Fix the following compilation warning with clang trunk in isci(4):
sys/dev/isci/isci_task_request.c:198:7: error: case value not in enumerated type 'SCI_TASK_STATUS' (aka 'enum _SCI_TASK_STATUS') [-Werror,-Wswitch]
    case SCI_FAILURE_TIMEOUT:
           ^

This is because the switch is done on a SCI_TASK_STATUS enum type, but
the SCI_FAILURE_TIMEOUT value belongs to SCI_STATUS instead.

Because the list of SCI_TASK_STATUS values cannot be modified at this
time, use the simplest way to get rid of this warning, which is to cast
the switch argument to int.  No functional change.

f11c7f6305 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.
