2009-10-13x86/paravirt: Use normal calling sequences for irq enable/disableJeremy Fitzhardinge
Bastian Blank reported a boot crash with stackprotector enabled, and debugged it back to edx register corruption. For historical reasons irq enable/disable/save/restore had special calling sequences to make them more efficient. With the more recent introduction of higher-level and more general optimisations this is no longer necessary so we can just use the normal PVOP_ macros. This fixes some residual bugs in the old implementations which left edx liable to inadvertent clobbering. Also, fix some bugs in __PVOP_VCALLEESAVE which were revealed by actual use.

2009-10-13eeepc-laptop: Prevent a panic when disabling RT2860 wireless when associatedDarren Salt
This works around what I think is actually a bug in rt2860sta which is triggered when the hardware "disappears" from beneath the driver, i.e. when wireless is toggled off via ACPI. It does so by ensuring that the rfkill soft-block flag is set before the hardware is disabled. I do not know whether this patch is required if rt2800pci is in use instead of rt2860sta; at the time of submission of this patch, I've not been able to test this.

2009-10-13ACPI / PCI: Fix NULL pointer dereference in acpi_get_pci_dev() (rev. 2)Rafael J. Wysocki
acpi_get_pci_dev() may be called for a non-PCI device, in which case it should return NULL. However, it assumes that every handle it finds in the ACPI CA name space, between given device handle and the PCI root bridge handle, corresponds to a PCI-to-PCI bridge with an existing secondary bus. For this reason, when it finds a struct pci_dev object corresponding to one of them, it doesn't check if its 'subordinate' field is a valid pointer. This obviously leads to a NULL pointer dereference if acpi_get_pci_dev() is called for a non-PCI device with a PCI parent which is not a bridge. To fix this issue make acpi_get_pci_dev() check if pdev->subordinate is not NULL for every device it finds on the path between the root bridge and the device it's supposed to get to and return NULL if the "target" device cannot be found. http://bugzilla.kernel.org/show_bug.cgi?id=14129 (worked in 2.6.30, regression in 2.6.31) Signed-off-by: Rafael J.

This too follows the ARM change, given that the issue at hand applies to all platforms that implement lazy D-cache writeback. This fixes up the case when a page mapping disappears between the flush_dcache_page() call (when PG_dcache_dirty is set for the page) and the update_mmu_cache() call -- such as in the case of swap cache being freed early. This kills off the mapping test in update_mmu_cache() and switches to simply testing for PG_dcache_dirty.

2009-10-12mac80211: document ieee80211_rx() context requirementJohannes Berg
ieee80211_rx() must be called with softirqs disabled since the networking stack requires this for netif_rx() and some code in mac80211 can assume that it can not be processing its own tasklet and this call at the same time. It may be possible to remove this requirement after a careful audit of mac80211 and doing any needed locking improvements in it along with disabling softirqs around netif_rx(). An alternative might be to push all packet processing to process context in mac80211, instead of to the tasklet, and add other synchronisation.

2009-10-12mac80211: fix ibss raceJohannes Berg
When a scan completes, we call ieee80211_sta_find_ibss(), which is also called from other places. When the scan was done in software, there's no problem as both run from the single-threaded mac80211 workqueue and are thus serialised against each other, but with hardware scan the completion can be in a different context and race against callers of this function from the workqueue (e.g. due to beacon RX). So instead of calling ieee80211_sta_find_ibss() directly, just arm the timer and have it fire, scheduling the work, which will invoke ieee80211_sta_find_ibss() (if that is appropriate in the current state).

2009-10-12ARM: force dcache flush if dcache_dirty bit setNitin Gupta
On ARM, update_mmu_cache() does dcache flush for a page only if it has a kernel mapping (page_mapping(page) != NULL). The correct behavior would be to force the flush based on dcache_dirty bit only. One of the cases where present logic would be a problem is when a RAM based block device[1] is used as a swap disk. In this case, we would have in-memory data corruption as shown in steps below: do_swap_page() { - Allocate a new page (if not already in swap cache) - Issue read from swap disk - Block driver issues flush_dcache_page() - flush_dcache_page() simply sets PG_dcache_dirty bit and does not actually issue a flush since this page has no user space mapping yet. - Now, if swap disk is almost full, this newly read page is removed from swap cache and corrsponding swap slot is freed. - Map this page anonymously in user space. - update_mmu_cache() - Since this page does not have kernel mapping (its not in page/swap cache and is mapped anonymously), it does not issue dcache flush even if dcache_dirty bit is set by flush_dcache_page() above. <user now gets stale data since dcache was never flushed> } Same problem exists on mips too.

2009-10-12Run pci_apply_final_quirks() sooner.David Woodhouse
Having this as a device_initcall() means that some real device drivers can actually initialise _before_ the quirks are run, which is wrong. We want it to run _before_ device_initcall(), but _after_ fs_initcall(), since some arch-specific PCI initialisation like pcibios_assign_resources() is done at fs_initcall(). We could use rootfs_initcall() but I actually want to use that for the IOMMU initialisation, which has to come after the quirks, but still before the real devices. So use fs_initcall_sync() instead -- since this is entirely synchronous, it doesn't hurt that it'll escape the synchronisation. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2009-10-12[ARM] pxa/csb726: adjust duplicate structure field initializationJulia Lawall
Currently the irq_type field of the csb726_lan_config structure is initialized twice. The value in the first case, SMSC911X_IRQ_POLARITY_ACTIVE_LOW, is normally stored in the irq_polarity field, so I have renamed the field in the first initialization to that.

2009-10-12perf tools: Fix const char type propagationRandy Dunlap
The following perf build warnings/errors in function argument types: builtin-sched.c:1894: warning: passing argument 1 of 'sort_dimension__add' discards qualifiers from pointer target type util/trace-event-parse.c:685: warning: passing argument 2 of 'read_expected' discards qualifiers from pointer target type util/trace-event-parse.c:741: warning: passing argument 4 of 'test_type_token' discards qualifiers from pointer target type util/trace-event-parse.c:706: warning: passing argument 2 of 'read_expected_item' discards qualifiers from pointer target type ... trigger because older GCC is not able to prove that sort_dimension__add() does not change the string. Some goes for test_type_token(). Fix this by improving type consistency.
