The patch is against 4.11-RELEASE, and is just a backport of your commit from Dec. 5th (http://lists.freebsd.org/pipermail/cvs-all/2004-December/094923.html). There haven't been any changes to amr since release, so it should apply directly to RELENG_4 as well.
I left out the subsequent ioctl fixes and LSI 320-2E support. They look straightforward, but I don't have the software or hardware to test them. If you'd like them in there before committing to RELENG_4, I can take a stab at it and post a new patch.
A new patch is attached to this message that synchronizes the RELENG_4 amr driver with CURRENT, minus the SMPng locking and amd64/ia64 ioctl compatibility stuff. The fixes and their corresponding file revisions are:
Greater than 4GB support
amr.c 1.55, 1.56, 1.59
amr_cam.c 1.10
amr_pci.c 1.24
amrvar.h 1.23ioctl fixes for LSI management tools
amr.c 1.60, 1.61Fix module unloading
amr_cam.c 1.12
amrvar.h 1.24Check for NULL amrd_sc in amrd_dump
amr_disk.c 1.32Support for LSI 320-2E PCI Express controller
amr_pci.c 1.27
amrreg.h 1.8
amrvar.h 1.26The only part of the patch I've tested is the >4GB support. The rest compiles but I can't vouch for its validity because I don't have the software or hardware to test.
amr-4.x-MFC.patch
