2010-02-22PCI PM: Add function for checking PME status of devicesRafael J. Wysocki
Add function pci_check_pme_status() that will check the PME status bit of given device and clear it along with the PME enable bit. It will be necessary for PCI run-time power management. Based on a patch from Shaohua Li <shaohua.li@intel.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-02-22PCI: mark is_pcie obsoleteKenji Kaneshige
The "is_pcie" field in struct pci_dev is no longer needed because struct pci_dev has PCIe capability offset in "pcie_cap" field and (pcie_cap != 0) means the device is PCIe capable. This patch marks "is_pcie" fields obsolete. Current users of "is_pcie" field are: - drivers/ssb/scan.c - drivers/net/wireless/ath/ath9k/pci.c - drivers/net/wireless/ath/ath5k/attach.c - drivers/net/wireless/ath/ath5k/reset.c - drivers/acpi/hest.c - drivers/pci/pcie/pme/pcie_pme.c Will post patches for each to use pci_is_pcie() as a follow-up.

2010-02-22PCI: update bridge resources to get more big ranges in PCI assign unssignedYinghai Lu
BIOS separates IO ranges between several IOHs, and on some slots, BIOS assigns resources to a bridge, but stops assigning resources to the device under that bridge, because the device needs a big resource. So: 1. allocate resources and record the failed device resources 2. clear the BIOS assigned resources of the parent bridge of failing device 3. go back and call pci assign unassigned 4. if it still fails, go up the tree, clear more bridges. and try again Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2010-02-22PCI: Make pci_scan_slot more robustMatthew Wilcox
Yinghai pointed out that the new pci_scan_slot() crashes when called on an ARI-capable slot that is empty. Fix this by exiting early from pci_scan_slot if there is no device in the slot. Also make next_ari_func() robust against devices not existing in case the ARI capability is corrupt. ARI also requires that the devices be listed in order, so if we find a function listed that is out of order, stop scanning to prevent loops.

2010-02-22PCI: Clean up build for CONFIG_PCI_QUIRKS unsetRafael J. Wysocki
Currently, drivers/pci/quirks.c is built unconditionally, but if CONFIG_PCI_QUIRKS is unset, the only things actually built in this file are definitions of global variables and empty functions (due to the #ifdef CONFIG_PCI_QUIRKS embracing all of the code inside the file). This is not particularly nice and if someone overlooks the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced. To clean that up, move the definitions of the global variables in quirks.c that are always built to pci.c, move the definitions of the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to headers (additionally make these functions static inline) and modify drivers/pci/Makefile so that quirks.c is only built if CONFIG_PCI_QUIRKS is set.

2010-02-22PCI: Rewrite pci_scan_slotMatthew Wilcox
The Alternate Routing-ID Interpretation capability allows a single device to have up to 256 functions. They can be populated sparsely, so the current technique of scanning every eighth function is not guaranteed to find them all. By introducing a 'next_fn' function pointer, we can use the linked list of functions in the ARI capability to scan all the functions which exist. We can then speed up the pci_scan_slot by skipping the scan of subsequent devfns for PCIe devices which are the direct children of Root Ports or Downstream Ports. These devices are only permitted to implement device 0, unless they are ARI devices, in which case they'll be scanned by the ARI code above.

2010-02-22i915 / PM: Fix hibernate regression caused by suspend/resume splittingRafael J. Wysocki
Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.

2010-02-20ARM: allow alignment fault mode to be configured at kernel bootRussell King
Some glibc versions intentionally create lots of alignment faults in their gconv code, which if not fixed up, results in segfaults during boot. This can prevent systems booting properly. There is no clear hard-configurable default for this; the desired default depends on the nature of the userspace which is going to be booted. So, provide a way for the alignment fault handler to be configured via the kernel command line. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-02-20CacheFiles: Fix a race in cachefiles_delete_object() vs renameDavid Howells
cachefiles_delete_object() can race with rename. It gets the parent directory of the object it's asked to delete, then locks it - but rename may have changed the object's parent between the get and the completion of the lock. However, if such a circumstance is detected, we abandon our attempt to delete the object - since it's no longer in the index key path, it won't be seen again by lookups of that key. The assumption is that cachefilesd may have culled it by renaming it to the graveyard for later destruction.
