If the ssi or codec drivers are not loaded (for instance, because spi or i2c
bus drivers are not loaded), returning -EINVAL will for people to unload and
then reload the module to get sound working. Returning E_PROBE_DEFER will
mitigate this.

ad1884_fixup_hp_eapd() tries to set the NID for controlling the
speaker EAPD from the pin configuration. But the current code can't
work expectedly since it sets spec->eapd_nid before calling the
generic parser where the autocfg pins are set up.
This patch changes the function to set spec->eapd_nid after the
generic parser call while it sets vmaster hook unconditionally. The
spec->eapd_nid check is moved in the hook function itself instead.

"We discovered some breakage in our "EEH" (PCI Error Handling) code

them is due to a patch (37f02195be "powerpc/pci: fix PCI-e devices

have merged considering that it caused more problems than it solved.
Please pull those two fixes. One for a simple EEH address cache
initialization issue. The other one is a patch from Guenter that I
had originally planned to put in 3.11 but which happens to also fix
that other regression (a kernel oops during EEH error handling and
possibly hotplug).
With those two, the couple of test machines I've hammered with error
injection are remaining up now. EEH appears to still fail to recover
on some devices, so there is another problem that Gavin is looking
into but at least it's no longer crashing the kernel."

Commit 37f02195b (powerpc/pci: fix PCI-e devices rescan issue on powerpc
platform) fixes a problem with interrupt and DMA initialization on hot
plugged devices. With this commit, interrupt and DMA initialization for
hot plugged devices is handled in the pci device enable function.
This approach has a couple of drawbacks. First, it creates two code paths
for device initialization, one for hot plugged devices and another for devices
known during the initial PCI scan. Second, the initialization code for hot
plugged devices is only called when the device is enabled, ie typically
in the probe function. Also, the platform specific setup code is called each
time pci_enable_device() is called, not only once during device discovery,
meaning it is actually called multiple times, once for devices discovered
during the initial scan and again each time a driver is re-loaded.
The visible result is that interrupt pins are only assigned to hot plugged
devices when the device driver is loaded. Effectively this changes the PCI
probe API, since pci_dev->irq and the device's dma configuration will now
only be valid after pci_enable() was called at least once. A more subtle
change is that platform specific PCI device setup is moved from device
discovery into the driver's probe function, more specifically into the
pci_enable_device() call.
To fix the inconsistencies, add new function pcibios_add_device.
Call pcibios_setup_device from pcibios_setup_bus_devices if device setup
is not complete, and from pcibios_add_device if bus setup is complete.
With this change, device setup code is moved back into device initialization,
and called exactly once for both static and hot plugged devices.
[ This also fixes a regression introduced by the above patch which
causes dev->irq to be overwritten under some cirumstances after
MSIs have been enabled for the device which leads to crashes due
to the MSI core "hijacking" dev->irq to store the base MSI number
and not the LSI. --BenH

Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
in the middle of 'ubifs_readdir()'.
This means that 'file->private_data' can be freed while 'ubifs_readdir()' uses
it, and this is a very bad bug: not only 'ubifs_readdir()' can return garbage,
but this may corrupt memory and lead to all kinds of problems like crashes an
security holes.
This patch fixes the problem by using the 'file->f_version' field, which
'->llseek()' always unconditionally sets to zero. We set it to 1 in
'ubifs_readdir()' and whenever we detect that it became 0, we know there was a
seek and it is time to clear the state saved in 'file->private_data'.
I tested this patch by writing a user-space program which runds readdir and
seek in parallell. I could easily crash the kernel without these patches, but
could not crash it with these patches.

Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
in the middle of 'ubifs_readdir()'.
First of all, this means that 'file->private_data' can be freed while
'ubifs_readdir()' uses it. But this particular patch does not fix the problem.
This patch is only a preparation, and the fix will follow next.
In this patch we make 'ubifs_readdir()' stop using 'file->f_pos' directly,
because 'file->f_pos' can be changed by '->llseek()' at any point. This may
lead 'ubifs_readdir()' to returning inconsistent data: directory entry names
may correspond to incorrect file positions.
So here we introduce a local variable 'pos', read 'file->f_pose' once at very
the beginning, and then stick to 'pos'. The result of this is that when
'ubifs_dir_llseek()' changes 'file->f_pos' while we are in the middle of
'ubifs_readdir()', the latter "wins".

This fixes the problem that "init=" options may not be passed to kernel
correctly.
parse_mem_cmdline() of mn10300 arch gets rid of "mem=" string from
redboot_command_line. Then init_setup() parses the "init=" options from
static_command_line, which is a copy of redboot_command_line, and keeps
the pointer to the init options in execute_command variable.
Since the commit 026cee0 upstream (params: <level>_initcall-like kernel
parameters), static_command_line becomes overwritten by saved_command_line at
do_initcall_level(). Notice that saved_command_line is a command line
which includes "mem=" string.
As a result, execute_command may point to weird string by the length of
"mem=" parameter.
I noticed this problem when using the command line like this:
mem=128M console=ttyS0,115200 init=/bin/sh
Here is the processing flow of command line parameters.
start_kernel()
setup_arch(&command_line)
parse_mem_cmdline(cmdline_p)
* strcpy(boot_command_line, redboot_command_line);
* Remove "mem=xxx" from redboot_command_line.
* *cmdline_p = redboot_command_line;
setup_command_line(command_line) <-- command_line is redboot_command_line
* strcpy(saved_command_line, boot_command_line)
* strcpy(static_command_line, command_line)
parse_early_param()
strlcpy(tmp_cmdline, boot_command_line, COMMAND_LINE_SIZE);
parse_early_options(tmp_cmdline);
parse_args("early options", cmdline, NULL, 0, 0, 0, do_early_param);
parse_args("Booting ..", static_command_line, ...);
init_setup() <-- save the pointer in execute_command
rest_init()
kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND);
At this point, execute_command points to "/bin/sh" string.
kernel_init()
kernel_init_freeable()
do_basic_setup()
do_initcalls()
do_initcall_level()
(*) strcpy(static_command_line, saved_command_line);
Here, execute_command gets to point to "200" string !!
