to not using splbio(), and has rotted a little. The races were
probably harmless in practice because this function was only used
for superblock updates, and separate superblock updates are probably
prevented from running into each other by doing part of the update
synchronously.
alternative, I present .. ta! da! .. the __error() hack.
This patch to the a.out dynamic loader provides old a.out binaries
with __error() if they are linked with an older libc that lacks it,
but are also linked against a library that needs it.
There is a smaller, tricker hack that takes advantage of the fact
that ld.so has __error() too, courtesy of the new libc, but this
hack is the straightforward version.
end of the main options section.
Turned on documented option OVERRIDE_TUNER. LINT is primarily
for turning on options, not for documenting them.
Don't list IPFILTER twice (once as broken).
which makes adjtime(2) useless and confuses xntpd(8) into refusing
to start even when it would use the kernel PLL instead of adjtime().
The result is the same as recommended by tickadj(8), at least when
HZ divides 10^6. Of course, you wouldn't want to actually use
adjtime() when HZ is large. In the silly boundary case of HZ == 10^6,
tickadj == tick == 1 so the clock stops while adjtime() is active.
mmioctl() to fix hundreds of style bugs and a few error handling bugs
(don't check for superuser privilege for inappropriate ioctls, don't
check the input arg for the output-only MEM_RETURNIRQ ioctl, and don't
return EPERM for null changes).
(a) Note that the default securelevel value is -1, in -current and -stable.
(b) Mention kernel sysctl variable that controls securelevel.
(c) Add warning the `fsck' will fail if securelevel >= 2.
(d) Suggest end of /etc/rc as the right place to raise securelevel.
and one spelling fix.

doesn't work with libc/net/res_stubs.c since gas wants the weak reference
to take place in the same context as the real definition, presumably so
that it can get hold of the symbol typing etc.
However, this doesn't matter for libc/elf since we don't have binaries
that use the old symbol names.
`void *' arg. Fixed or hid most of the resulting type mismatches.
Handlers can now be updated locally (except for reworking their
global declarations in isa_device.h).
