I received an DBAU1200 eval kit from AMD a few days ago and tried to
enable the USB2 port, but the current linux-2.6 GIT did not even
compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and
CONFIG_USB_OHCI set.
Furthermore, in ehci-hcd.c, platform_driver_register() was called with
an improper argument of type 'struct device_driver *' which of course
ended up in a kernel oops. How could that ever have worked on your
machines?

Anyway, here's a trivial patch that makes the USB subsystem working
on my board for both OHCI and EHCI.
It also removes the /* FIXME use "struct platform_driver" */.

Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.

To fix this three things are needed.

#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports

The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.

The actual chip setup done by the quirk is the precise setup recommended
by the vendor.

(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

sysfs has a different i_mutex lock order behavior for i_mutex than the
other filesystems; sysfs i_mutex is called in many places with subsystem
locks held.  At the same time, many of the VFS locking rules do not apply
to sysfs at all (cross directory rename for example).  To untangle this
mess (which gives false positives in lockdep), we're giving sysfs inodes
their own class for i_mutex.

Based on a patch from Ernie Petrides

During security research, Red Hat discovered a behavioral flaw in core
dump handling. A local user could create a program that would cause a
core file to be dumped into a directory they would not normally have
permissions to write to. This could lead to a denial of service (disk
consumption), or allow the local user to gain root privileges.

The prctl() system call should never allow to set "dumpable" to the
value 2. Especially not for non-privileged users.

This can be split into three cases:

  1) running as root -- then core dumps will already be done as root,
     and so prctl(PR_SET_DUMPABLE, 2) is not useful

  2) running as non-root w/setuid-to-root -- this is the debatable case

  3) running as non-root w/setuid-to-non-root -- then you definitely
     do NOT want "dumpable" to get set to 2 because you have the
     privilege escalation vulnerability

With case #2, the only potential usefulness is for a program that has
designed to run with higher privilege (than the user invoking it) that
wants to be able to create root-owned root-validated core dumps. This
might be useful as a debugging aid, but would only be safe if the program
had done a chdir() to a safe directory.

There is no benefit to a production setuid-to-root utility, because it
shouldn't be dumping core in the first place. If this is true, then the
same debugging aid could also be accomplished with the "suid_dumpable"
sysctl.

This is confirmed to fix a hang due to PCI resource conflicts with

Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:

  "From the docs available i would _guess_ this thing is really similar
   to the 82443BX/82371AB combination.  at least the SMBus base address
   register is hidden at the very same place (32bit at 0x90 in function
   3 of the "south" brigde)"

The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:

  "I am trying to find the register information. 440MX is an integration of
   440BX north-bridge without AGP and PIIX4E (82371EB).  PIIX4 quirk
   should cover the ACPI and SMBus related I/O registers."

and verified to fix the problem by Alessio.
