PPC PMAC driver
Here is a patch to correct detection of the soundcard on my iBook model
(bought really recently).
Without that fix, there were only andui in the headphone, and the mixer
was totaly non functional.

A new function snd_card_set_generic_dev() is introduced to add the
'generic device' support for devices without proper bus on sysfs.
It's a last resort, and should be removed in future when they have
a proper bus, instead.

CA0106 driver,EMU10K1/EMU10K2 driver
A thread appeared on the LKML. This patch implements the fix.
Question:
in sysfs, /sys/bus/*/drivers lists the driver names, with their exported .name (eg. '.name = 'EMU10K1_Audigy'' in the module code, from now on 'driver name'). In /sys/modules, the kernel modules are listed with their module name, eg. snd_emu10k1. However, it seems to me that in sysfs, there is no way in particular to tell, which module has which .name. That is, that snd_emu10k1 is EMU10K1_Audigy and vice versa.
I wonder whether it wouldn't be possible to add a symlink to the particular module from the driver, and/or from the module to the driver, so the list of devices handled by the module and the module name would be accessible. This way, I would know which driver name corresponds to which module name and vice versa.
Answer:
For PCI drivers, just add the line:
.owner = THIS_MODULE,
to their struct pci_driver definition and you will get the symlink
created for you.

- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is
as follows:
/*
* Get or set a debug register. The first 16 are DABR registers and the
* second 16 are IABR registers.
*/
#define PTRACE_GET_DEBUGREG 25
#define PTRACE_SET_DEBUGREG 26
DABR == data breakpoint and IABR = instruction breakpoint in IBM
speak. We could split out the IABR into 2 more ptrace calls but I
figured there was no need and 16 DABR registers should be more
than enough (POWER4/POWER5 have one).
- Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt

This adds code which gives us the option on ppc64 of instantiating the
PCI tree (the tree of pci_bus and pci_dev structs) from the Open
Firmware device tree rather than by probing PCI configuration space.
The OF device tree has a node for each PCI device and bridge in the
system, with properties that tell us what addresses the firmware has
configured for them and other details.
There are a couple of reasons why this is needed. First, on systems
with a hypervisor, there is a PCI-PCI bridge per slot under the PCI
host bridges. These PCI-PCI bridges have special isolation features
for virtualization. We can't write to their config space, and we are
not supposed to be reading their config space either. The firmware
tells us about the address ranges that they pass in the OF device
tree.
Secondly, on powermacs, the interrupt controller is in a PCI device
that may be behind a PCI-PCI bridge. If we happened to take an
interrupt just at the point when the device or a bridge on the path to
it was disabled for probing, we would crash when we try to access the
interrupt controller.
I have implemented a platform-specific function which is called for
each PCI bridge (host or PCI-PCI) to say whether the code should look
in the device tree or use normal PCI probing for the devices under
that bridge. On pSeries machines we use the device tree if we're
running under a hypervisor, otherwise we use normal probing. On
powermacs we use normal probing for the AGP bridge, since the device
for the AGP bridge itself isn't shown in the device tree (at least on
my G5), and the device tree for everything else.
This has been tested on a dual G5 powermac, a partition on a POWER5
machine (running under the hypervisor), and a legacy iSeries
partition.

Reported by: Manuel Lauss <mano@roarinelk.homelinux.net>
He was getting random initial video modes depending on the kernel
configuration. His option line includes 'extvga'.
The i810fb documentation describes the option 'extvga', however the
driver accepts 'ext_vga'. Besides 'extvga' being ignored by i810fb,
it also confuses the option parser of i810fb and assigns 'extvga' to
'mode_option'. This leads to an incorrect video mode at boot time.

Move call to get_mm_counter() in update_mem_hiwater() to be

Modify the end check for munmap regions to allow for the
legacy behavior of 0 being valid. Pretty much all current
uClinux system libc malloc's pass in 0 as the end point.
A hard check will fail on these, so change the check so
that if it is non-zero it must be valid otherwise it fails.
A passed in value will always succeed (as it used too).
