bba483a33a Correct a bug that was somehow both obvious and hard-to-see. :-)
An incorrectly-sized allocation was being made due to an incorrect
argument to the `sizeof' operator.  Obvious, because it violated the
`foo = malloc(sizeof(*foo))' idiom.  Hard-to-see, because it was a
missing `*' (`*p' versus `**p').

Resulting failure was

7b2d1b3027 Add an i386-specifc hack to always set %gs. There still seems
to be instances where the kernel doesn't  properly save and/or
restore it.

Use noupcall and nocompleted flags in the KSE mailbox.  These
require kernel changes to work which will be committed sometime
later.  Things still work without the changes.

Remove the general kse entry function and use two different
functions -- one for scope system threads and one for scope
process threads.  The scope system function is not yet enabled
and we use the same function for all threads at the moment.

Keep a copy of the KSE stack for the case that a KSE runs
a scope system thread and uses the same stack as the thread
(no upcalls are generated, so a separate stack isn't needed).
This isn't enabled yet.

Use a separate field for the KSE waiting flag.  It isn't
correct to use the mailbox flags field.

The following fixes were provided by David Xu:

  o Initialize condition variable locks with thread versions
    of the low-level locking functions instead of the kse versions.

  o Enable threading before creating the first thread instead
    of after.

  o Don't enter critical regions when trying to malloc/free
    or call functions that malloc/free.

  o Take the scheduling lock when inheriting thread attributes.

  o Check the attribute's stack pointer instead of the
    attributes stack size for null when allocating a
    thread's stack.

  o Add a kseg reinit function so we don't have to destroy and
    then recreate the same lock.

  o Check the return value of kse_create() and return an
    appropriate error if it fails.

  o Don't forget to destroy a thread's locks when freeing it.

  o Examine the correct flags word for checking to see if
    a thread is in a synchronization queue.

Things should now work on an SMP kernel.

8b257c5e50 Add support for ia64.
Note that the tp register (r13) is reserved as the TLS pointer in
the same way that that gp register (r1) is reserved as the global
pointer. This implementation uses the tp register to point to the
thread structure used by the threads implementation. This is not
in violation with the runtime specification provided the TLS is
a fixed distance from the thread structure. This is only an issue
when code used the __thread keyword to create TLS. This is not
supported at the moment.

d53b36cf85 Don't use `memset' to initialize a struct passwd. A module
may not fill in all fields, and in the case of string fields, this could

5d56aa9cb2 Revamp libpthread so that it has a chance of working in an SMP
environment.  This includes support for multiple KSEs and KSEGs.

The ability to create more than 1 KSE via pthread_setconcurrency()
is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads.
Those should come shortly.

There are still some known issues which davidxu and I are working
on, but it'll make it easier for us by committing what we have.

This library now passes all of the ACE tests that libc_r passes
with the exception of one.  It also seems to work OK with KDE
including konqueror, kwrite, etc.  I haven't been able to get
mozilla to run due to lack of java plugin, so I'd be interested
to see how it works with that.
