- Remove a redundant variable in mpt_pci_attach(). - #if 0 the currently unused paired port linking and unlinking of dual adapters. - Simplify MSI/MSI-X allocation and release. For a single one, we don't need to fiddle with the MSI/MSI-X count and pci_release_msi(9) is smart enough to just do nothing in case of INTx. - Canonicalize actions taken on attach failure and detach. - Remove the remainder of incomplete support for older FreeBSD versions.

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result. Similar to the (1 << 31) case it is not defined to do (2 << 30). This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD.

Fix several target mode SIMs to not blindly clear ccb_h.flags field of ATIO CCBs. Not all CCB flags there belong to them.

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot. Submitted by: jhb Reviewed by: jfv, marius, achadd, achim MFC after: 1 day

Move hptmv and mpt drivers shutdown a bit later to the SHUTDOWN_PRI_LAST
