git: kernel - Move mplock to machine-independent C
commit 684a93c4b15cf9f678dcf209702dadcd4f670406
Author: Matthew Dillon <dillon@apollo.backplane.com>

kernel - Move mplock to machine-independent C
* Remove the per-platform mplock code and move it all into
machine-independent code: sys/mplock2.h and kern/kern_mplock.c.
* Inline the critical path.
* When a conflict occurs kern_mplock.c will KTR log the file and line
number of both the holder and conflicting acquirer. Set
debug.ktr.giant_enable=-1 to enable conflict logging.
