Also, remove all usages of the CS_CHECK macro and replace them with proper

Some newer Lenovo models are shipped with a TPM that doesn't seem to set the TPM_STS_DATA_EXPECT status bit
when sending it a burst of data, so the code understands it as a failure and doesn't proceed sending the chip
the intended data. In this patch we bypass this bit check in case the itpm module parameter was set.
This patch is based on Andy Isaacson's one:
http://marc.info/?l=linux-kernel&m=124650185023495&w=2
It was heavily discussed how should we deal with identifying the chip in kernel space, but the required
patch to do so was NACK'd:
http://marc.info/?l=linux-kernel&m=124650186423711&w=2
This way we let the user choose using this workaround or not based on his

virtio: add virtio IDs file
moved all device IDs into a single file. While the change itself is
a very good one, it can break userspace applications. For example
if a userspace tool wanted to get the ID of virtio_net it used to
include virtio_net.h. This does no longer work, since virtio_net.h
does not include virtio_ids.h.
This patch moves all "#include <linux/virtio_ids.h>" from the C
files into the header files, making the header files compatible with
the old ones.

This way all flush_to_ldisc work is always done through the workqueues,
and we thus have a single point of serialization. It also means that we
can avoid calling flush_to_ldisc() entirely if there was no delayed work
pending.
[ Side note: using workqueues and keventd as the single way to enter
flush_to_ldisc() still doesn't absolutely guarantee that we can't have
concurrency: keventd is multithreaded and has a thread per CPU, and
while the WORK_STRUCT_PENDING bit guarantees a single work only being
on the pending list once, the work might be both pending and _running_
at the same time. Workqueues are not simple. ]
This was also confirmed to fix bugzilla #14388, even without the earlier
locking fix and cleanup (commit c8e331419: "tty: Make flush_to_ldisc()
locking more robust"). So both commits fix the same bug differently,
and either would have worked on its own. But I'm committing them both
since they are cleanups independent of each other.

The locking logic in this function is extremely subtle, and it broke
when we started doing potentially concurrent 'flush_to_ldisc()' calls in
commit e043e42bdb ("pty: avoid forcing
'low_latency' tty flag").
The code in flush_to_ldisc() used to set 'tty->buf.head' to NULL, with
the intention that this would then cause any other concurrent calls to
not do anything (locking note: we have to drop the buf.lock over the
call to ->receive_buf that can block, which is why we can have
concurrency here at all in the first place).
It also used to set the TTY_FLUSHING bit, which would then cause any
concurrent 'tty_buffer_flush()' to not free all the tty buffers and
clear 'tty->buf.tail'. And with 'buf.head' being NULL, and 'buf.tail'
being non-NULL, new data would never touch 'buf.head'.
Does that sound a bit too subtle? It was. If another concurrent call to
'flush_to_ldisc()' were to come in, the NULL buf.head would indeed cause
it to not process the buffer list, but it would still clear TTY_FLUSHING
afterwards, making the buffer protection against 'tty_buffer_flush()' no
longer work.
So this clears it all up. We depend purely on TTY_FLUSHING for handling
re-entrancy, and stop playing games with the buffer list entirely. In
fact, the buffer list handling is now robust enough that we could
probably stop doing the whole "protect against 'tty_buffer_flush()'"
thing entirely.
However, Alan also points out that we would probably be better off
simplifying the locking even further, and just take the tty ldisc_mutex
around all the buffer flushing calls. That seems like a good idea, but
in the meantime this is a conceptually minimal fix (with the patch
itself being bigger than required just to clean the code up and make it
readable).
This fixes keyboard trouble under X:

struct agp_file_private *priv;
struct agp_client *client;
Call-outs:
kzalloc should be safe to call under the mutex_lock

- agp_mmap calls that under agp_fe.agp_mutex which we hold in agp_open
- agpioc_reserve_wrap calls it without any locking what-so-ever.
- Is that an error? Or is that okay because it has pid that is
a unique handle?

- This function only manipulates struct agp_file_private, once again

The generic open callback for the mem class devices is "protected" by
the bkl.
Let's look at the datas manipulated inside memory_open:
- inode and file: safe
- the devlist: safe because it is constant
- the memdev classes inside this array are safe too (constant)
After we find out which memdev file operation we need to use, we call
its open callback. Depending on the targeted memdev, we call either
open_port() that doesn't manipulate any racy data (just a capable()
check), or we call nothing.
So it's safe to remove the big kernel lock there.

A couple of people have hit the WARN_ON() in drivers/char/tty_io.c,
tty_open() that is unhappy about seeing the tty line discipline go away
during the tty hangup. See for example
http://bugzilla.kernel.org/show_bug.cgi?id=14255
and the reason is that we do the tty_ldisc_halt() outside the
ldisc_mutex in order to be able to flush the scheduled work without a
deadlock with vhangup_work.
However, it turns out that we can solve this particular case by
- using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits
for just the particular work, rather than synchronizing with any
random outstanding pending work.
This won't deadlock, since the buf.work we synchronize with doesn't
care about the ldisc_mutex, it just flushes the tty ldisc buffers.
- realize that for this particular case, we don't need to wait for any
hangup work, because we are inside the hangup codepaths ourselves.
so as a result we can just drop the flush_scheduled_work() entirely, and
then move the tty_ldisc_halt() call to inside the mutex. That way we
never expose the partially torn down ldisc state to tty_open(), and hold
the ldisc_mutex over the whole sequence.

David Howells noticed (due to the compiler warning about an unused

that implements TIOCSPTLCK for legacy pty handling. It's been that way
since 2.6.26, commit 3e8e88ca05 to be
exact ("pty: prepare for tty->ops changes").
DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do. But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.
And clean it up a bit while we're at it.

Author: Alan Cox <alan@linux.intel.com>
Date: Sat Sep 19 13:13:22 2009 -0700
tty: make the kref destructor occur asynchronously
Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:
INIT open /dev/console Input/output error
It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229
The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.
Fix it as per the following Alan's suggestion:
Fun but it's actually not a bug and the fix is wrong in itself as
the port may be closing but not yet being destructed, in which case
it seems to do the wrong thing. Opening a tty that is closing (and
could be closing for long periods) is supposed to return -EIO.
I suspect a better way to deal with this and keep the old console
timing is to split tty->shutdown into two functions.
tty->shutdown() - called synchronously just before we dump the tty
onto the waitqueue for destruction
tty->cleanup() - called when the destructor runs.
We would then do the shutdown part which can occur in IRQ context
fine, before queueing the rest of the release (from tty->magic = 0
... the end) to occur asynchronously
The USB update in -next would then need a call like
if (tty->cleanup)
tty->cleanup(tty);
at the top of the async function and the USB shutdown to be split
between shutdown and cleanup as the USB resource cleanup and final
tidy cannot occur synchronously as it needs to sleep.
In other words the logic becomes
final kref put
make object unfindable
async
clean it up
