As the latter is used for the timecounter on certain machine models, using a spin lock in this case can lead to a deadlock with the upcoming callout(9) rework. - Merge r134227/r167250 from x86: Avoid cross-IPI SMP deadlock by using the smp_ipi_mtx spin lock not only for smp_rendezvous_cpus() but also for the MD cache invalidation and TLB demapping IPIs. - Mark some unused function arguments as such. 2012-01-29T00:47:11Z Marius Strobl marius@FreeBSD.org 2012-01-29T00:47:11Z urn:sha1:0c572d8109f73be313fe81cf78c7ab226009c964 Add multiple inclusion protection. 2011-12-31T14:12:12Z Hans Petter Selasky hselasky@FreeBSD.org 2011-12-31T14:12:12Z urn:sha1:0105e7b57ec82d3d157edb9f4322f29f05d54f6e Use DEVMETHOD_END to mark end of device methods. Remove superfluous device methods. Add some missing __FBSBID() macros. 2011-11-07T13:40:54Z Marius Strobl marius@FreeBSD.org 2011-11-07T13:40:54Z urn:sha1:66b280587642b9c7bf1e293ff48954cdfabfe421 Add a PCI front-end to esp(4) allowing it to support AMD Am53C974 and replace amd(4) with the former in the amd64, i386 and pc98 GENERIC kernel configuration files. Besides duplicating functionality, amd(4), which previously also supported the AMD Am53C974, unlike esp(4) is no longer maintained and has accumulated enough bit rot over time to always cause a panic during boot as long as at least one target is attached to it (see PR 124667).

A new feature flag NCR_F_LARGEXFER was introduced so we just need to check for this one and not for individual controllers supporting large transfers in several places. - Let the LSI64854 core load transfer buffers using BUS_DMA_NOWAIT as the NCR53C9x core can't handle EINPROGRESS. Due to lack of bounce buffers support, sparc64 doesn't actually use EINPROGRESS and likely never will, as an example for writing additional front-ends for the NCR53C9x core it makes sense to set BUS_DMA_NOWAIT anyway though. - Some minor cleanup.
