If an arch doesn't define cpumask_of_cpu_map, create a generic statically-initialized one for them. This allows removal of the buggy cpumask_of_cpu() macro (&cpumask_of_cpu() gives address of out-of-scope var). An arch with NR_CPUS of 4096 probably wants to allocate this itself based on the actual number of CPUs, since otherwise they're using 2MB of rodata (1024 cpus means 128k). That's what CONFIG_HAVE_CPUMASK_OF_CPU_MAP is for (only x86/64 does so at the moment). In future as we support more CPUs, we'll need to resort to a get_cpu_map()/put_cpu_map() allocation scheme.

This module harvests more than just memory errors, it also harvests various bus and dma errors that the Chipset detects. Previously, it would report all such errors, which would cause output to be TOO loud. This patches therefore adds a parameter which is used to turn off NON-MEMORY error reports by default. Or the reporting can be enabled via the parameter Also did code style cleanup: less than 80 characters per line rule Signed-off-by:

The channel DIMM label does not seem to be used much in the edac code. However, where it is used (in the core code), it is assumed to not have a newline embedded. This leaves the sysfs file newline free which looks funny when cat'ing it. Here we just add the trailing newline to the sysfs chX_dimm_label output... [Doug Thompson note: the DIMM label is one of the primary uses of EDAC. User space daemon scripts, edac-utils@sourceforge, populate the DIMM label fields, via /sys/devices/system/edac attributes, with the silk screen labels of the motherboard in use. dmidecode access BIOS tables, but BIOS tables are well known to be incorrect and useless in these respects. edac-utils will strip off any newlines before its use of the output, when displaying DIMM slot silk screen labels.

When updating the edac_mc_poll_msec module parameter from the sysfs /sys/module/edac_core/parameters/edac_mc_poll_msec file, we don't update the workq timers. So that, if we move from a big poll time to a small one, the small one won't take effect until the big one has timed out. Here we provide a new module parameter set method to call out to the update routine. This brings the /sys/module/edac_core/parameters functionality up to that provided by the /sys/drivers/system/edac/mc sysfs module parameter files so that we can remove them or at least link to the /sys/module files...

Static kobjects are not supported in linux kernel. Convert the edac_pci_top_main_kobj from static to dynamic. This avoids the double free of the edac_pci_top_main_kobj.name that we see on module reload of the e752x edac driver (and probably others as well). In addition Greg KH <greg@kroah.com> has pointed out that this code may be cleaned up significantly. I will look at that as a follow-on patch, for now, I just want the minimum fix to get this double-free oops bug squashed... Many thanks to Greg KH for his patience in showing me what the Documentation/kobject.txt already said (oops)... Signed-off-by:

Some code cleanliness issues found by Andrew Morton (thanks!) which should not affect functionality, but which should help make the code more maintainable. In particular, we now: * convert all #define's w/ a parameter to static inlines * use 1UL rather than 1ULL when calculating an unsigned long * use pci_disable_device The resulting code is tested and seems to work fine...

Preliminary support for the Intel 5100 MCH. CE and UE errors are reported along with the current DIMM label information and other memory parameters. Reasons why this is preliminary: 1) This chip has 2 independent memory controllers which, for best perforance, use interleaved accesses to the DDR2 memory. This architecture does not map very well to the current edac data structures which depend on symmetric channel access to the interleaved data. Without core changes, the best I could do for now is to map both memory controllers to different csrows (first all ranks of controller 0, then all ranks of controller 1). Someone much more familiar with the edac core than I will probably need to come up with a more general data structure to handle the interleaving and de-interleaving of the two memory controllers. 2) I have not yet tackled the de-interleaving of the rank/controller address space into the physical address space of the CPU. There is nothing fundamentally missing, it is just ending up to be a lot of code, and I'd rather keep it separate for now, esp since it doesn't work yet... 3) The code depends on a particular i5100 chip select to DIMM mainboard chip select mapping. This mapping seems obvious to me in order to support dual and single ranked memory, but it is not unique and DIMM labels could be wrong on other mainboards. There is no way to query this mapping that I know of. 4) The code requires that the i5100 is in 32GB mode. Only 4 ranks per controller, 2 ranks per DIMM are supported. I do not have hardware (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks per controller) mode. 5) The serial presence detect code should be broken out into a "real" i2c driver so that decode-dimms.pl can work.

Implement the get_parent export operation by sending a LOOKUP request with ".." as the name. Implement looking up an inode by node ID after it has been evicted from the cache. This is done by seding a LOOKUP request with "." as the name (for all file types, not just directories). The filesystem can set the FUSE_EXPORT_SUPPORT flag in the INIT reply, to indicate that it supports these special lookups. Thanks to John Muir for the original implementation of this feature.

Implement export_operations, to allow fuse filesystems to be exported to NFS. This feature has been in the out-of-tree fuse module, and is widely used and tested. It has not been originally merged into mainline, because doing the NFS export in userspace was thought to be a cleaner and more efficient way of doing it, than through the kernel. While that is true, it would also have involved a lot of duplicated effort at reimplementing NFS exporting (all the different versions of the protocol). This effort was unfortunately not undertaken by anyone, so we are left with doing it the easy but less efficient way. If this feature goes in, the out-of-tree fuse module can go away, which would have several advantages: - not having to maintain two versions - less confusion for users - no bugs due to kernel API changes Comment from hch: - Use the same fh_type values as XFS, since we use the same fh encoding.

Allow filesystem's ->lock() method to call posix_lock_file() instead of posix_lock_file_wait(), and return FILE_LOCK_DEFERRED. This makes it possible to implement a such a ->lock() function, that works with the lock manager, which needs the call to be asynchronous. Now the vfs_lock_file() helper can be used, so this is a cleanup as well. Signed-off-by:
