pms(4): Limit maximum I/O size to 256KB instead of 1MB. There is a weird limit of AGTIAPI_MAX_DMA_SEGS (128) S/G segments per I/O since the initial driver import. I don't know why it was added, can only guess some hardware limitation, but in worst case it means maximum I/O size of 508KB. Respect it to be safe, rounding to 256KB.

Make MAXPHYS tunable. Bump MAXPHYS to 1M. Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work. Changes to cam/, dev/ahci, dev/ata, dev/mpr, dev/mpt, dev/mvs, dev/siis, where either submitted by, or based on changes by mav.

Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name) The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are fixed-length strings. AFAICT the only place they're read is in sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated. However, the kernel doesn't null-terminate them. A bunch of copy-pasted code uses strncpy to write them, and doesn't guarantee null-termination. For at least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually overflows. You can see the result by doing "camcontrol negotiate da0 -v". This change null-terminates those fields everywhere they're set in the kernel. It also shortens a few strings to ensure they'll fit within the 16-character field.

sys: use our roundup2/rounddown2() macros when param.h is available. rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement. This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted.

Don't forget to check the vendor when probing. Also, there's no need to double check for if the card has probed before. In fact, there's no reason to single check either. Simplify the code as a result. $FreeBSD$ added to lxutil.c in a non-standard way to help keep the diffs with upstream to a minimum. Differential Revision: https://reviews.freebsd.org/D3263
