[SCSI] sym2 version 2.2.1
sym2 version 2.2.1: - Fix MMIO BAR detection (Thanks to Bob Picco) - Fix odd-sized transfers with a wide bus (Thanks to Larry Stephens) - Write posting fixes (Thanks to Thibaut Varene) - Change one of the GFP_KERNEL allocations back into a GFP_ATOMIC - Make CCB_BA() return a script-endian address - Move range checks and disabling of devices from the queuecommand path to slave_alloc() - Remove a warning in sym_setup_cdb() - Keep a pointer to the scsi_target instead of the scsi_dev in the tcb - Remove a check for the upper layers passing an oversized cmd - Replace CAM_REQ_ constants with the Linux DID_ constants - Replace CAM_DIR_ constants with the Linux DMA_ constants - Inline sym_read_parisc_pdc() on non-parisc systems Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
