The BUG_ON(p->ptrace) will be called if the CLONE_DETACH process is
traced.  This patch removes BUG_ON(p->ptrace), and also removes a
workaround for it in sys_wait4().

driver remove the ftont of the queue from the request list
and cache it in 'current_req'.

This simplifies the driver and should be a lot more robust.

Still, I'll probably go blind just for _looking_ at the dang
sources of this thing. Whee.

This should finally fix the 2.5.x floppy driver.

This fixes the pnpbios CS check to check for the correct values (it
wasn't up to date with the various GDT reshuffles), moves it inside the
kernel mode check, modifies it so that it takes less instructions and
marks it with unlikely().

Note that the 2.5.32 version of this check will cause the kernel to
always panic since it checks for the kernel segments and will thus
decide to jump to the pnpbios fault handler without being in pnpbios.
pnpbios_core.c instead seems to use the correct values.

Gotta ptrace_unlink before calling release_task, and instead of fiddling
with the real_parent directly.

drivers/net/ppp_generic.c: Fix byte-aligned packets, nearly every arch csum_partial cannot handle this.

- If an iptables rule is using --ulog-nlgroup with a
value greated than 4, we crash
- Remove a memory leak when someone throws packets at
the ulog netlink socket

partitions. The higher layers do a better job of it.

sk_inuse should be bigger than "char" as we can
have more than 255 server threads.  Due to the way the count
is used, this is unlikely to actually cause a problem, but it
should nonetheless be fixed.

Also, two printk generate more noise than we would like,
so turn them into dprintk (debugging printk).

sock_writeable determines whether there is space in a socket's output
buffer.  socket write_space callbacks use it to determine whether to wake
up those that are waiting for more output buffer space.

however, sock_writeable is not appropriate for TCP sockets.  because the
RPC layer's write_space callback uses it for TCP sockets, the RPC layer
hammers on sock_sendmsg with dozens of write requests that are only a few
hundred bytes long when it is trying to send a large write RPC request.
this patch adds logic to the RPC layer's write_space callback that
properly handles TCP sockets.

patch reviewed by Trond and Alexey.

when several RPC requests want to reconnect a TCP transport socket at
once, xprt_lock_write serializes the tasks to prevent multiple socket
connects.  however, TCP connects are always done by a RPC child task that
has no request slot.  xprt_lock_write can oops if there is no request slot
allocated to the invoking RPC task.  reviewed and accepted by Trond.

the xprt_lock_write changes are not yet in 2.4, so this patch does not
apply to 2.4.

This fixes a bad TLS initialization bug found by Andi Kleen.  x86/SMP
only worked due to luck.

This adds two scheduler related fixes:

 - changes the migration code to use struct completion. Andrew pointed out
   that there might be a small window in where the up() touches the
   semaphore while the waiting task goes on and frees its stack. And
   completion is more suited for this kind of stuff anyway.

 - removes two unneeded exports, pointed out by Andrew.

This moves CLONE_SETTID and CLONE_CLEARTID handling into kernel/fork.c,
where it belongs.  [the CLONE_SETTLS is x86-specific and thus remains in
the per-arch process.c] This makes support for these two new flags much
easier: architectures only have to pass in the user_tid pointer.

It would be helpful if these msr.h #defines could get in.
