Modified Files: src/sys/dev/usb [netbsd-9]: xhci.c xhcivar.h Log Message: Pull up following revision(s) (requested by riastradh in ticket #1687): sys/dev/usb/xhci.c: revision 1.176 sys/dev/usb/xhcivar.h: revision 1.23 xhci(4): Defer root intr xfers while polling. Root intr xfers require taking adaptive locks, which is forbidden while polling. This is not great -- any USB transfer completion callbacks might try to take adaptive locks, not just uhub_intr, and that will always causes trouble. We get lucky with ukbd_intr because it's not MP-safe, so it relies only on the kernel lock (a spin lock) anyway. But this change brings xhci in line with ehci.
