from old signal handlers. This is simpler and faster, and fixes (new)
sigreturn(2) when %eip in the new signal context happens to match the
magic value (0x1d516). 0x1d516 is below the default ELF text section,
so this probably never broken anything in practice.
locore.s:
In addition, don't build the signal trampoline for old signal handlers
when it is not used.
alpha:
Not fixed, but seems to be even less broken in practice due to more
advanced magic. A false match occurs for register #32 in mc_regs[].
Since there is no hardware register #32, a false match is only possible
for direct calls to sigreturn(2) that happen to have the magic number
in the spare mc_regs[32] field.

call VOP_INACTIVE before placing the vnode back on the free list.
Otherwise there is a race condition on SMP machines between
getnewvnode() locking the vnode to reclaim it and vrele()
locking the vnode to inactivate it. This window of vulnerability
becomes exaggerated in the presence of filesystems that have
been suspended as the inactive routine may need to temporarily
release the lock on the vnode to avoid deadlock with the syncer
process.

threads race for a file slot.
dup2(2) incorrectly assumes that if it needs to grow the ofiles
array that it will get what it wants. This assertion was valid
before we allowed shared filedescriptor tables but is now incorrect.
The assertion can trigger superfolous panics if the thread doing a
dup2 looses a race with another thread while possibly blocked in
the MALLOC call in fdalloc. Another thread may grab the slot we
are requesting which makes fdalloc return something other than what
we asked for, this will triggering the bogus assertion.

signal trampoline for old signals. The arches that support old signals
currently abuse sigreturn(2) instead. This mainly complicates things
and slightly breaks the the new sigreturn(2).
COMPAT is too limited to support the correct configuration of osigreturn,
and this commit doesn't attempt to fix it; it just moves the bogusness:
osigreturn() must now be provided unconditionally even on arches that
don't really need it; previously it had to be provided under the bogus
condition defined(COMPAT_43).

some arches and the syscall table is machine-independent. It was
(bogusly) conditional on COMPAT_43, so this usually makes no difference.
ia64: in addition:
- replace the bogus cloned comment before osigreturn() by a correct one.
osigreturn() is just a stub fo ia64's.
- fix the formatting of cloned comment before sigreturn().
- fix the return code. use nosys() instead of returning ENOSYS to get
the same semantics as if the syscall is not in the syscall table.
Generating SIGSYS is actually correct here.
- fix style bugs.
powerpc: copy the cleaned up ia64 stub. This mainly fixes a bogus comment.
sparc64: copy the cleaned up the ia64 stub, since there was no stub before.

for SMP in the plain profiling case. It seems to work too.
This error was not detected by LINT because LINT only compiles the
GUPROF profiling case, which is is a superset of the plain profiling
case for !SMP but which is so broken for SMP that the buggy code is
not compiled.

to fetch the magic word instead of useracc() plus a direct access.
This is more efficient as well as simpler and less incorrect:
- it was inefficent because useracc() takes much longer than just
accessing the data using a correct access method, at least on i386's.
- it was incorrect because direct access is incorrect unless the address
has been mapped. This and nearby direct accesses are mostly handled
better for other arches because they have to be (direct accesses don't
work).
- using magic in sigreturn is still fundamentally broken because false
matches are possible. On i386's, a false match occurs when %eip in a
new signal context happens to equal the magic value. This is not
handled better for other arches.

npx is no more mandatory than sc. Its mandatoryness went away in
rev.1.226 of i386/machdep.c 9 months before it was made mandatory in
rev.1.24 of config/mkmakefile.c.
This change is mainly to test building of minimal kernel configurations.
npx should really be even more standard than clk. It was optional mainly
so that the usual device driver configuration info could be specified in
the usual way in config files, but this hasn't been necessary for a few
years.

harmful as well as bogus, since it includes "isa_if.h" which is not
generated when isa is not configured.
This was fixed in 1999 but was broken by unconditionalizing PNPBIOS.
