Merge r254263:

2013-08-13T22:05:50Z

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.

Give MEXTADD() another argument to make both void pointers to the

free function controlable, instead of passing the KVA of the buffer storage as the first argument. Fix all conventional users of the API to pass the KVA of the buffer as the first argument, to make this a no-op commit. Likely break the only non-convetional user of the API, after informing the relevant committer. Update the mbuf(9) manual page, which was already out of sync on this point. Bump __FreeBSD_version to 800016 as there is no way to tell how many arguments a CPP macro needs any other way. This paves the way for giving sendfile(9) a way to wait for the passed storage to have been accessed before returning. This does not affect the memory layout or size of mbufs. Parental oversight by: sam and rwatson. No MFC is anticipated.

Remove the __inline qualifier from a function which is in fact not an
