The following patch to net/sk98lin/skvpd.c was put together by Marc Bouget,
mbouget at club-internet.fr.

This patch works around a corrupt EEPROM (VPD?) in the ASUS K8V Deluxe SE
motherboard ethernet chipset and allows the network driver to work
correctly.  We have written to ASUS and the sk98lin maintainers but have
not heard anything back.

the Broadcom BCM4401 driver restores pci configuration on resume only when the 
device is up. On my notebook, this leads to a failure when the device is down 
during the S3 cycle. Short solution for now: Always restore pci config.

Also included are driver version update and change logs

Reduce scope of tx_lock

1) Provides support for new FarSync cards T1U, T2U, T4U and TE1
2) Provides support for an E1 interface
3) Provides support for a variant of X.21 that allows transmit and
receive clocks
4) Provide a raw socket interface directly to the data from the line.
5) Improves performance with less time in interrupts and more in BH's

Presently 2.6.6 backs out the CONFIG_8139_RXBUF_IDX in favor of using a
hardcoded 8139_RXBUF_IDX (again). This seems to have been done due to
some issues occuring with 8139_RXBUF_IDX =3D=3D 3, however (as the Kconfig
pointed out), we still need 8139_RXBUF_IDX =3D=3D 1 in the CONFIG_SH_DREAMC=
AST
case.

The patch which made this change can be seen at:

{MIME-mangled URL}

Before that, CONFIG_8139_RXBUF_IDX was set to 1 both in the
CONFIG_SH_DREAMCAST and CONFIG_EMBEDDED cases. This patch adds that
back into the current 8139too.

This fixes an oops on unmount (failure of the assertation at
fs/ext3/super.c:421).  Probably reproduceable just by creating and deleting a
single symlink over nfs and then unmounting the exported filesystem.

Recent change to fh_compose means dentry reference is *not* consumed, and so
usually has to be explicitly dput afterwards.  One usage was missed in that
patch, so this dput is needed.

Fix a CPU Hotplug problem wherein idle task's "->prio" value is not
restored to MAX_PRIO during CPU_DEAD handling.  Without this patch, once a
CPU is offlined and then later onlined, it becomes "more or less" useless
(does not run any task other than its idle task!)

Ingo said:

  The __setscheduler() call is (technically) incorrect because in the
  SCHED_NORMAL case the prio should be zero.  So it's a bit cleaner to set up
  the static priority to MAX_PRIO and then revert the policy to SCHED_NORMAL
  via __setscheduler().

We need to set file->f_ra _after_ calling blkdev_open(), when inode->i_mapping
points at the right thing.  And we need to get it from
inode->i_mapping->host->i_mapping too, which represents the underlying device.

Also, don't test for null file->f_mapping in the O_DIRECT checks.

In researching the oopses reported in bug #2761, Neil came up with:

I have found one problem, but it isn't particularly new and I cannot
 see how it would be related.

When d_alloc_anon creates an anonymous dentry, it is put on a special hash
chain for anonymous dentries (sb->s_anon), but d_bucket is set to 

   d_hash(parent, name_hash)

If, when it is eventually moved to a proper name, that hash value is the same
as the final hash value, it will not be moved to the right bucket, and so it
not be accessible by name.  This patch should fix it.



anonymous dentries have their own private hash "bucket" (sb->s_anon) and so
d_bucket should be set to a unique (impossible) address, else d_move will
get confused.

There is a race between unshare_files() and the following steal_locks().
As a consequence, steal_locks() may steal some additional FL_POSIX locks
that don't belong to the current thread.  This triggers a BUG in
locks_remove_flock().

In detail, the current thread shares its files struct with other threads.
This causes unshare_files() to associate the current thread with a copy of
its files_struct.  The copy shares all file objects with the original files
struct.  In the time between unshare_files() and steal_locks(), another
thread creates a new file and a FL_POSIX lock on it.  The current thread
gets into steal_locks() and takes over all FL_POSIX locks that refer to the
previous files_struct, including the new lock.  We do
put_files_struct(original files_struct).  This causes the file handle to
the new file to be closed.  We get into locks_remove_posix() and miss the
lock, because its fl_owner field now refers to the new files_struct. 
Finally we get into locks_remove_flock(), and stumble upon the lock.

While looking into this bug report I gathered the following data with a
SUSE kernel (oops and LKCD dump from Chris):

put_files_struct+0x67 is equivalent to fs/binfmt_elf.c:681 in 2.6.6

current->files == fl->fl_owner
fl->fl_file = 0xf6702b80 (a valid struct file)

current->files =

  max_fdset=1024
  next_fd=3
  fd=[0xf6927080 0xf6951b80  0xf6951b80 0 ...]

Here's a proposed fix.  As a side effect, steal_locks no longer walks the
global list of locks, but only the locks of all open inodes.

What are the reasons (other than historic ones) for not getting rid of
fl_owner and using fl_pid instead, by the way?  I think that would clean up
the whole mess with file locks a bit.

ptep_establish() is used to establish a new mapping at COW time,
and it always replaces a non-writable page mapping with a totally
new page mapping that is dirty (and likely writable, although ptrace
may cause a non-writable new mapping). Because it was nonwritable,
we don't have to worry about losing concurrent dirty page bit updates.

ptep_update_access_flags() leaves the same page mapping, but updates
the accessed/dirty/writable bits (it only ever sets them, and never
removes any permissions). Often easier, but it may race with a dirty
bit update on another CPU.

Booted on x86 and ppc64.
