The origin of this code comes from patches at sourceforge, that allow EDAC to be updated to various kernels. With kernel version 2.6.20 a new workq system was installed, thus the patches needed to be modified based on the kernel version.

Move dev_name() macro to a more generic interface since it's not possible to determine whether a device is pci, platform, or of_device easily.

2007-07-19drivers/edac: add new nmi rescanDave Jiang
Provides a way for NMI reported errors on x86 to notify the EDAC subsystem pending ECC errors by writing to a software state variable. Here's the reworked patch. I added an EDAC stub to the kernel so we can have variables that are in the kernel even if EDAC is a module. I also implemented the idea of using the chip driver to select error detection mode via module parameter and eliminate the kernel compile option. Please review/test. Thx! Also, I only made changes to some of the chipset drivers since I am unfamiliar with the other ones. We can add similar changes as we go.

2007-07-19drivers/edac: add edac_device classDouglas Thompson
This patch adds the new 'class' of object to be managed, named: 'edac_device'. As a peer of the 'edac_mc' class of object, it provides a non-memory centric view of an ERROR DETECTING device in hardware. It provides a sysfs interface and an abstraction for varioius EDAC type devices. Multiple 'instances' within the class are possible, with each 'instance' able to have multiple 'blocks', and each 'block' having 'attributes'. At the 'block' level there are the 'ce_count' and 'ue_count' fields which the device driver can update and/or call edac_device_handle_XX() functions. At each higher level are additional 'total' count fields, which are a summation of counts below that level. This 'edac_device' has been used to capture and present ECC errors which are found in a a L1 and L2 system on a per CORE/CPU basis.

2007-07-19drivers/edac: split out functions to unique filesDouglas Thompson
This is a large patch to refactor the original EDAC module in the kernel and to break it up into better file granularity, such that each source file contains a given subsystem of the EDAC CORE. Originally, the EDAC 'core' was contained in one source file: edac_mc.c with it corresponding edac_mc.h file. Now, there are the following files: edac_module.c The main module init/exit function and other overhead edac_mc.c Code handling the edac_mc class of object edac_mc_sysfs.c Code handling for sysfs presentation edac_pci_sysfs.c Code handling for PCI sysfs presentation edac_core.h CORE .h include file for 'edac_mc' and 'edac_device' drivers edac_module.h Internal CORE .h include file This forms a foundation upon which a later patch can create the 'edac_device' class of object code in a new file 'edac_device.c'.

2007-07-19lguest: the guest codeRusty Russell
lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's 5000 lines and self-contained. Performance is ok, but not great (-30% on kernel compile). But given its hackability, I expect this to improve, along with the paravirt_ops code which it supplies a complete example for. There's also a 64-bit version being worked on and other craziness. But most of all, lguest is awesome fun! Too much of the kernel is a big ball of hair. lguest is simple enough to dive into and hack, plus has some warts which scream "fork me!".

Introduce the pm_power_off_prepare() callback that can be registered by the interested platforms in analogy with pm_idle() and pm_power_off(), used for preparing the system to power off (needed by ACPI).

2007-07-19swsusp: introduce restore platform operationsRafael J. Wysocki
At least on some machines it is necessary to prepare the ACPI firmware for the restoration of the system memory state from the hibernation image if the "platform" mode of hibernation has been used. Namely, in that cases we need to disable the GPEs before replacing the "boot" kernel with the "frozen" kernel (cf. http://bugzilla.kernel.org/show_bug.cgi?id=7887). After the restore they will be re-enabled by hibernation_ops->finish(), but if the restore fails, they have to be re-enabled by the restore code explicitly. For this purpose we can introduce two additional hibernation operations, called pre_restore() and restore_cleanup() and call them from the restore code path. Still, they should be called if the "platform" mode of hibernation has been used, so we need to pass the information about the hibernation mode from the "frozen" kernel to the "boot" kernel in the image header. Apparently, we can't drop the disabling of GPEs before the restore because of Bug #7887 .  We also can't do it unconditionally, because the GPEs wouldn't have been enabled after a successful restore if the suspend had been done in the 'shutdown' or 'reboot' mode. In principle we could (and probably should) unconditionally disable the GPEs before each snapshot creation *and* before the restore, but then we'd have to unconditionally enable them after the snapshot creation as well as after the restore (or restore failure)   Still, for this purpose we'd need to modify acpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we'd have to introduce some mechanism synchronizing the disablind/enabling of the GPEs with the device drivers' .suspend()/.resume() routines and with disable_/enable_nonboot_cpus().  However, this would have affected the suspend (ie. s2ram) code as well as the hibernation, which I'd like to avoid in this patch series.

2007-07-18[TG3]: Fix msi issue with kexec/kdump.Michael Chan
Tina Yang <tina.yang@oracle.com> discovered an MSI related problem when doing kdump. The problem is that the kexec kernel is booted without going through system reset, and as a result, MSI may already be enabled when tg3_init_one() is called. tg3_init_one() calls pci_save_state() which will save the stale MSI state. Later on in tg3_open(), we call pci_enable_msi() to reconfigure MSI on the chip before we reset the chip. After chip reset, we call pci_restore_state() which will put the stale MSI address/data back onto the chip. This is no longer a problem in the latest kernel because pci_restore_state() has been changed to restore MSI state from internal data structures which will guarantee restoring the proper MSI state. But I think we should still fix it. Our save and restore sequence can still cause very subtle problems down the road. The fix is to have our own functions save and restore precisely what we need. We also change it to save and restore state inside tg3_chip_reset() in a more straight forward way. Thanks to Tina for helping to test and debug the problem.

2007-07-18UIO: Hilscher CIF card driverHans-Jürgen Koch
this is a patch that adds support for Hilscher CIF DeviceNet and Profibus cards. I tested it on a Kontron CPX board, and Thomas reviewed it. You can find the user space part here: http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gz Notes: cif_api.c is the main file you want to look at. It contains the functions to open, close, mmap and so on. cif_dps.c adds functions specific to Profibus cards, and cif_dn.c contains functions for DeviceNet cards. cif.c is a universal playground, it's just a small test program. The user space part of this UIO driver is still work in progress, and not everything is tested yet. At the moment, the thread in cif_api.c contains some code that artificially makes the card generate interrupts, this was added for testing and will be removed later. But the driver already contains all the functions needed for useful operation, so it gives a good idea of how such a thing looks like. For comparison, here's what you get from the manufacturer (www.hilscher.com) when you ask for a Linux 2.6 driver: http://www.tglx.de/private/hjk/cif-orig-2.6.tar.bz2 WARNING: Don't look at the code for too long, you might become sick :-) Signed-off-by: Hans-Jürgen Koch <hjk@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-18UIO: Add the User IO core codeHans J. Koch
This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses. See the docbook documentation for more details on how to use this interface.

Check for return value of sysfs_create_link() in device_add() and device_rename(). Add helper functions device_add_class_symlinks() and device_remove_class_symlinks() to make the code easier to read.

2007-07-18dev_vdbg(), available with -DVERBOSE_DEBUGDavid Brownell
This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG. When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved out of a USB patch, but lots of drivers have similar support. That is, code can now be written to use an additional level of debug output, selected at compile time. Many driver authors have found this idiom to be very useful. A typical usage model is for "normal" debug messages to focus on fault paths and not be very "chatty", so that those messages can be left on during normal operation without much of a performance or syslog load. On the other hand "verbose" messages would be noisy enough that they wouldn't normally be enabled; they might even affect timings enough to change system or driver behavior.

2007-07-18PM: remove deprecated dpm_runtime_* routinesAlan Stern
This patch (as933) removes the deprecated dpm_runtime_suspend() and dpm_runtime_resume() routines from the PM core. The only user of those routines is the PCMCIA ds driver; local replacements are added.
