b47f638d85 Check in work done by bjc@openbsd.org, OpenBSD revs 1.4 and 1.5 of the 
same file. No other changes, OpenBSD log messages below.

> More EMODD work:
>         - Using CVTDL and subtracting to seperate integer from fraction does
>           not work if the integer is >32 bits long; instead, rearrange the bits
>           into a quadword, use ASHQ to truncate, and then subtract.
>
> Also:
>         - Set the condition codes properly; this fixes the other problem with
>           >32-bit-integer parts in libm by letting modf subtract the fractional
>           part (which *is* a double) to get the integral part in a double.

>         - move the zero checks earlier in the routine
>
>         - instead of 'ret' in zeroexit, use brw goback

> Switch a "BGTR foo" to a "BLSS bar; BRW foo; bar:".  In this case, the
> difference between the BGTR and foo: is too large for a byte displacement.
> as should give an error or at least a warning here, but it doesn't;
> instead it merrily outputs a completely bogus displacement.
> This fixes problems with EMODD on numbers with negative exponents.

1da9a91480 A bunch of fixes: 
- Make generic console routines not relying on running on master cpu.
- Add routine to start console transmitter (after IPI).
- Use real IPIs instead of the "console doorbell".
- Add routines cpu_send_ipi()/cpu_handle_ipi().
