e7c76e51e6 Add SIGFPE handling code. Report the proper SIGINFO ksi_code when a SIGFPE

481d181cd4 In cpu_getmcontext, make sure the returned MSR has the FP exception mode 
(PSL_FE0|PSL_FE1) saved in the PSL.  In cpu_setmcontext, copy the FP
exception bits to the PCB where they live.

847bed9428 Fix the way cpu_setmcontext was restoring FPSCR. Make the opposite of the 
way that cpu_getmcontext was saving it.  (FPSCR was being saved incorrectly
before and thus obliterated when a signal happened).

7681ce429d Make sure that the SRR1 we pass to userland reflects PSL_FE0|PSL_FE1 even 
if the lwp doesn't currently own the FPU.  When returning, copy those bits
back to the PCB.  (In case the user decided to the FP exception mode in the
signal handler).

4dc0aa3dee Don't add PSL_FE_FDLT to srr1, but put in pcb_flags. It will be added to

44003b5fca The FP exception mode bits from the MSR will be stored in pcb_flags. From 
there, they will copied to MSR as needed (when FP is enabled).  They will be
cleared from the MSR when the lwp loses the FPU.  Hence they need to be stored
someplace else.

0d6bda4d21 When returning back to user mode, if the lwp has lost the FPU, not only 
clear PSL_FP bit (to force a FPU Unavailable exception) but clear
PSL_FE0 and PSL_FE1 so that the FP execption mode is changes to ignore.
This will prevent spurious FP exceptions being made when the running lwp
doesn't own the FPU.

83d29714cc delay(): use =&r instead of =r for a temporary register as suggested in 
PR #24830. The bad reuse of the register was actually triggered by using
no optimization at all.
pmap_subr.c is the only file that still requires at least -O to compile
into working code (the proper fix would be to write almost all of
pmap_zero_page() in assembly). The rest of a macppc kernel requires only
-finline now.

fad92c3ca3 When we attach a channel, set a high level to DRV control pin of the 
external buffer for the PC card connected to the channel.  This hack

correctly detected.  A machine running with root on NFS can now be
properly rebooted.

8dd212dad7 Add option HD64461PCMCIA_REORDER_ATTACH that attaches channels in 
reversed order.

When you boot with two CF cards inserted, this options makes the one
in the "memory only" slot (channel 1), which is almost always the card
with the NetBSD install, attached as wd0.

Unlike using fixed unit numbers in the kernel config, if you boot with
only a single CF card, that single card will still be wd0 regardless
of which slot it is inserted in.

http://mail-index.netbsd.org/port-hpcsh/2003/10/23/0000.html provides
a more verbose description of why this option is convenient for most
usage patterns.

Fixes a problem reported by Shin'ichiro TAYA on port-powerpc.

Use "int(NUMBER)%256" instead of just "NUMBER" in the printf "%c"
statements in the awk script.  nawk was appearing to refuse outputing
a 0 byte of the low eight bits of the number were 0 but any higher
bits were set.
