boot CPU. This was the reason reboots on SMP systems could result in
weird hangs. Unlike the x86, we do not need to switch back to the boot
CPU in order to reboot the machine. See Section 3.4.5 of Part III
(Console Interface Architecture) from the Alpha Architecture Reference
Manual (aka the Brown Book) for more info.
It was foiled because of dynamic copy relocations that caused compile-time
space to be reserved in .bss and at run time a blob of data was copied to
that space and everything used the .bss version.. The problem is that
the space is reserved at compile time, not runtime... So we *still* could
not change the size of FILE. Sigh. :-(
Replace it with something that does actually work and really does let us
make 'FILE' extendable. It also happens to be the same as Linux does in
glibc, but has the slight cost of a pointer. Note that this is the
same cost that 'fp = fopen(), fprintf(fp, ...); fclose(fp);' has.
Fortunately, actual references to stdin/out/err are not all that common
since we have implicit stdin/out/err-using versions of functions
(printf() vs. fprintf()).
common_attach is wrong as common attach initialize some fileds used by
mediainit routine. This was hard to notify because loading driver as kld
lead to mediainit routine being called after common_attach, though probe_phy
is called before.

traps, so that ddb can keep control (almost) no matter how it is
entered. This breaks time-critical interrupts while the system is
stopped in ddb, but I haven't noticed any significant problems except
that applications become confused about the time. Lost time will be
adjusted for later. Anyway, the half-baked disabling of interrupts in
Debugger() gives the same problems for the usual way of entering ddb.
bug for bug compatibility to ddb trap handlers after fixing the debugger
trap gates to be interrupt gates, but the fix was never committed. Now
I want the fix to apply to ddb.
sys/i386/i386/mem.c: only the super-user may open /dev/io
regardless of the device permissions (just 4 years late!).
Also, add cross-reference to i386_{get,set}_ioperm(2).

the uses of it were wrong anyway.
o Always check for NULL returns on strdup(3).
o Fix a possible buffer overflow in strcpy(3).
o Fix a format string vulnerability.
o t->ty_type in stypeof() could be NULL and eventually cause
a segmentation fault in setenv(3), so check for that.

- fix segment limit mis-calculation for GCODE_SEL, GDATA_SEL, GPRIV_SEL,
LUCODE_SEL and LUDATA_SEL.
- move `loader(8) metadata' related printf() after cninit().
- use atop macro (address to pages) for segment limit calculation
instead of i386_btop macro (bytes to pages).
- fix style bugs for the declarations of ints.

_res.sort_list for backward compatibility. However, both sort_list's
are maintaind by just one index _res.nsort. So, when IPv6 address is
specified to sortlist, empty entry was created in _res.sort_list. It
broke sortlist facility of gethostbyname().
