This addresses kernel panic observed when sending SCSI UNMAP commands to SATA disks attached to isci(4). 1) Flesh out callback routines to allocate/free buffers needed for translating SCSI UNMAP data to ATA DSM data. 2) Add controller-level pool for storing buffers previously allocated for UNMAP translation, to lessen chance of no buffer available under memory pressure. 3) Ensure driver properly handles case where buffer pool is empty and contigmalloc returns NULL.

FreeBSD Driver for Intel(R) C600 SAS Controller =============================================== This driver has been developed for use with FreeBSD, version 9.0 and later. This driver uses an OS-agnostic abstraction layer library named SCIL that is published by Intel specifically for the C600 SAS controller. The SAS controller has no firmware, so the driver is extensive and using SCIL minimizes the development and maintenance cost of the driver. The FreeBSD implementation files are in the isci directory, and SCIL files are in the isci/scil subdirectory. As Intel publishes new versions of SCIL (to add features or fix bugs), the isci/scil subdirectory will be updated appropriately.
