<asm/systemcfg.h> is gone now, and the PCI error recovery constants in include/linux/pci.h changed their names in the process of getting accepted. Signed-off-by: -

242-eeh-no-percpu-counters.patch Remove per-cpu counters from the EEH code. These statistics counters are incremented at a very low frequency, and the performance gains of per-cpu variables are negligable. By contrast, the counters weren't safe against cpu off/online operations, and its not worth the effort to make them so (other than to turn them into plain globals). Signed-off-by:

240-ioremap-null-ptr-test.patch Under highly unusual circumstances, a buggy driver will ask a null ptr to be ioremapped, an operation that curently succeeds but leads to later trouble. Instead, refuse to remap the null pointer. Signed-off-by:

239-eeh-multifunction-consolidate.patch New-style firmware will often place multiple different functions under a non-EEH-aware parent. However, these devices might share a common PE "partition endpoint" and config address, ad thus any EEH events will affect all of the devices in common. This patch makes the effort to find all of these common devices and handle them together. Signed-off-by:

238-eeh-stop-if-reset_failed.patch If the firmware is unable to reset the PCI slot for some reason, then don't attempt any further recovery steps after that point. Instead, mark the device as permanently failed. Signed-off-by:

237-eeh-bridge-token.patch Minor: the rtas-bridge token should be set up the same way that all the other rtas tokens are set up. Signed-off-by:

236-eeh-config-addr.patch The PE configuration address wasn't being cnsistently used in all locations where a config address is called for. This patch adds it to the places it should have appeared in. Signed-off-by:

26-eeh-partition-endpoint.patch New versions of firmware introduce a new method by which the "partitionable endpoint" (the point at which the pci bus is cut) should be located. This code adds the support for this (mandatory) new feature. Signed-off-by:

25-pci-address-cache.patch The core EEH file is rather large. This patch splits out a self-contained chunk of it into its own file. This is the chunk that performes the caching and lookup of pci devices based on the i/o addresses of thier resoures. This code is almos architecture-independent and could be used by any system that wanted to find a pci device based only on the i/o address used by the device. Signed-off-by:

Various PCI bus errors can be signaled by newer PCI controllers. The core error recovery routines are architecture dependent. This patch adds a recovery infrastructure for the PPC64 pSeries systems. Signed-off-by:

I think it is better to set ->next_pending in the caller, when it is needed. This saves one parameter, and this coincides with cpu_quiet() beahaviour, which sets ->completed = ->cur itself. Signed-off-by:

The patch changes semaphores that are initialized as locked to complete(). Source: MontaVista Software, Inc. Modified-by:
Steven Rostedt <rostedt@goodmis.org> The following patch is from Montavista. I modified it slightly. Semaphores are currently being used where it makes more sense for completions. This patch corrects that. Signed-off-by:

This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different. Modified-by:

This patch switches XFS over to use the new mutex code directly as opposed to the previous workaround patch I posted earlier that avoided the namespace clash by forcing it back to semaphores. This falls in the 'works for me<tm>' category. Signed-off-by:

add the per-arch mutex.h files for the remaining architectures. We default to asm-generic/mutex-dec.h, because that performs quite well on most arches. Arches that do not have atomic decrement/increment instructions should switch to mutex-xchg.h instead. Arches can also provide their own implementation for the mutex fastpath primitives.

Ingo Molnar authored
Add three (generic) mutex fastpath implementations. The mutex-xchg.h implementation is atomic_xchg() based, and should work fine on every architecture. The mutex-dec.h implementation is atomic_dec_return() based - this one too should work on every architecture, but might not perform the most optimally on architectures that have no atomic-dec/inc instructions. The mutex-null.h implementation forces all calls into the slowpath. This is used for mutex debugging, but it can also be used on platforms that do not want (or need) a fastpath at all. Signed-off-by:
