This patch causes a regression: if CONFIG_PCI is not set, it doesn't compile
anymore. Here's a fix. I also killed a dead variable and its corresponding
warning:

From: Ronald Bultje <rbultje@ronald.bitfreak.net>

I suddenly noticed that 2.6.0-test4 seems to have removed the struct
device->name field, apparently for memory consumption reasons. Linus
changed this to pci_name((zr)->pci_dev) in my driver, and that's almost
correct, except that it is the PCI device ID, and I'm not supposed to
touch it. Also, since it's only 4 bytes, all my device names now show
like 'DC1' (this should be 'DC10plus') and alike.

The attached patch fixes this by going back to the behaviour that we
used in 2.4.x: we use a separate name field in our private driver
struct.

This patch adds some newlines between variable declarations and function

This patch adds pci_disable_device() to the card release function; we

This patch adds a release callback which frees the video_device struct.
This is needed to prevent freeing memory before it's not in use anymore,
as described in http://lwn.net/Articles/36850/. Without this, the driver
will give a warning when loaded. It might crash when unloading (see
article), too. The video4linux patch (by Gerd Knorr) was accepted a week
(or 2?) ago, but I forgot to adapt my driver to it.

From: Ronald Bultje <rbultje@ronald.bitfreak.net>

This patch renames the debug symbol to zr_debug because debug is already
defined somewhere else. Without it, it will cause a symbol conflict when
compiling this driver statically into the kernel. This was noticed by

This patch fixes several memleaks in error cases when the setup of i2c

s/spin_lock_irqrestore/spin_unlock_irqrestore/

It has no callers, is using the non-existent spin_lock_irqrestore(), and is
obviously very untested.  Kill.

I had second thoughts on this.

Reporting background writeout errors via close() only really makes sense if
allthe IO has completed anyway: ie, the app has had the fd open without
writing to it for many tens of seconds.

It would be OK if it was harmless, but it is not.  Changes are, applications
ignore errors from close().  So if an application does a fork/exit and the
child correctly does an fsync() of the fd, the close-on-exit will have wiped
out any accumulated EIO/ENOSPC errors.

Or if someone does dup()/close()/fsync(), the fsync() could fail to detect
earlier errors, thanks to the close.


So.  The clear-and-report of errors on close() makes the reporting of errors
on fsync/msync/fdatasync less reliable.

The patch below fixes a 2.6 mm problem.  Without this patch, zeromapped
pages are not flushed properly when they are swapped out.

What happens is that the page->index field is zero for page table pages
corresponding to the zeromapped range.  This causes ptep_to_address() to
return an incorrect virtual address with the result that PTEs are never
invalidated at swap-out...

The fix below mirrors the remap_pmd_range() case.

From: Andi Kleen <ak@muc.de>

Another a bit ugly but necessary patch for 32bit emulation.

Some applications including some versions of java break when the stack is
beyond the i386 standard 3GB boundary.  For these add a 3GB personality
that moves the stack to 3GB and fixes the beginning of the mmap area.  It's
a bit ugly, but better than not running these applications at all (e.g. 
the Oracle installer depends on such a buggy java :-().  It's also not only
Java, but some other programs as well.

The DAC960 driver uses an ugly overloading of the O_NONBLOCK flag to
support the controller's RAID configuration features.

Opening "/dev/rd/c0d0" with the O_NONBLOCK flag set returns a file
descriptor that can be used to do RAID control operations using ioctl().
The normal ioctl operations are not availabe with that file descriptor.

This patch removes that O_NONBLOCK overloading from DAC960_open() and
DAC960_ioctl() functions.  It introduces a new "miscellaneous" device
named /dev/dac960_gam.  It uses minor device number 252 of the miscellaneous
character devices.

The currently distrubted "Global Array Manager" server distrubted by
LSIlogic on their web page page works only on RH7.3 or earlier.  It doesn't
work under RH9.  There are probably some library incompatabilities.
So, I don't view this patch as breaking anything that currently works.
If this software package is ever brought up to date (which I doubt),
then it can be modified to use this new device at that time.

This patch against 2.6.0-test3-mm3 adds calls to the security_task_to_inode
hook to the pid*_revalidate functions to ensure that the inode security field
is also updated appropriately for /proc/pid inodes.  This corresponds with
the uid/gid update performed by the proc-pid-setuid-ownership-fix.patch that
is already in -mm3.

From: "B. D. Elliott" <bde@nwlink.com>

There's a bug:

- Someone reads a (say) root-owned process's /proc/pid/fd directory

  The inodes are instantiated owned by root.

- That process does a setuid

- The /proc/pid/* files still have the old ownerships.

This happened because we are now caching the proc entries.

The patch rewrites the ownership of the inodes under /proc/pid in the
d_revalidate() handler.

K7's (at least) are faulting in the prefetch instruction.  The AMD
engineers have said they will be getting back to us on it, and the fix is
looking complex, and nobody seems to be standing up to work on it.

So hum.  The usual manifestation is an oops in hlist_for_each(), down in
the VFS inode lookup code.  Disrupting our testers in this way is very bad,
so this patch just disables prefetch on all AMD parts in a rather stupid
way.

This fixes several calculation errors and races in entropy accounting
that would allow /dev/random output to greatly exceed the measured
entropy collection. This doesn't include any of my more controversial
hardening, it just makes it behave as intended.

It also corrects the operation of the 'catastrophic reseeding' feature
so that it will actually prevent the state extension attack it's meant
to guard against.

And finally, it also fixes a couple missed wake-up and accidental
sleep bugs uncovered by the above fixes.

Debug instrumentation has been improved to help verify correctness.

This patch adds locking for SMP. Apparently Willy never managed to
revive his laptop with his version so I revived mine.

The batch pool is copied as a block to avoid long lock hold times
while mixing it into the primary pool. 

Two locks are added:

gobal batch_lock
   batch_entropy_store can be called from any context, and typically from
   interrupts -> spin_lock_irqsave

   batch_entropy_process is called called via schedule_delayed_work and
   runs in process context -> spin_lock_irq

entropy_store.lock
   the mixing process is too expensive to be called from an interrupt
   context and the basic worker function extract_entropy can sleep, so
   all this stuff can be under a normal spin_lock

When building a kernel right after 'make mrproper' resulted in a very short
run, and no sign that .config was missing.  This has been fixed by adding a
new rule for .config in the top-level Makefile, and a new target
'silentoldconfig' in scripts/kconfig/Makefile.
