We only have one syscall table: inline sysent/SYS_MAXSYSCALL and SYS_syscall as the nosys() function into the MD syscall entry routines and the SYSCALL_DEBUG support. Adjust alpha's syscall check to match the other archs. Also, make sysent const to get it into .rodata. With that, 'struct emul' is unused: delete it and all its references ok millert@

When we are rebooting, do not fail in uvn_io(). The vnodes are revoked while syncing disk, so the processes lose their executable pages. Instead of killing them with a SIGBUS after page fault, just sleep. This should prevent that init dies without pages followed by a kernel panic. initial diff from tedu@; OK deraadt@ tedu@

There is a bunch of places in the kernel entry points where we don't hold the kernel lock, but still need call one function that needs it. Instead of grabbing the lock all over the place, move the locks into the affected functions: trapsignal, scdebug*, ktrsyscall, ktrsysret, systrace_redirect and ADDUPROF. In the cases we already hold the biglock we'll just recurse. kettenis@, beck@ ok
