        src/sys/kern: sys_syscall.c

Log Message:
syscall(2): Provide better attribution for biglock slippage.

This adds a small overhead to the syscall path, but only when invoked
via the syscall(2) syscall, for which stack traces generally don't
print the actual syscall number in question so the better attribution
may make a difference.
