MFC r280347: Remove MAXBSIZE use from drivers where it has nothing to do.

2015-04-21T11:27:50Z

In some cases limits are just not needed, in others -- DFLTPHYS is the right constant to use instead.

Update the CAM API for FreeBSD 10:

2013-09-24T16:50:53Z

- Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0; MPSAFE drivers should be managing their own timeout storage. The remaining non-MPSAFE drivers have been modified to also manage their own storage, and should be considered for updating to MPSAFE (or removal) during the FreeBSD 10.x lifecycle. - Add fields related to soft timeouts and quality of service, to be used in upcoming work. - Add room for more flags in the CCB header and path_inq structures. - Begin support for extended 64-bit LUNs. - Bump the CAM version number to 0x18, but add compat shims. Tested with camcontrol and smartctl. Reviewed by: nathanw, ken, kib Approved by: re Obtained from: Netflix

every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.
