The comments above __alloc_bootmem_node() claim that the code will first try the allocation using 'goal' and if that fails it will try again but with the 'goal' requirement dropped. Unfortunately, this is not what the code does, so fix it to do so. This is important for nobootmem conversions to architectures such as sparc where MAX_DMA_ADDRESS is infinity. On such architectures all of the allocations done by generic spots, such as the sparse-vmemmap implementation, will pass in: __pa(MAX_DMA_ADDRESS) as the goal, and with the limit given as "-1" this will always fail unless we add the appropriate fallback logic here.

This patch instructs DLM to prevent an "in place" conversion, where the lock just stays on the granted queue, and instead forces the conversion to the back of the convert queue. This is done on upward conversions only. This is useful in cases where, for example, a lock is frequently needed in PR on one node, but another node needs it temporarily in EX to update it. This may happen, for example, when the rindex is being updated by gfs2_grow. The gfs2_grow needs to have the lock in EX, but the other nodes need to re-read it to retrieve the updates. The glock is already granted in PR on the non-growing nodes, so this prevents them from continually re-granting the lock in PR, and forces the EX from gfs2_grow to go through.

Mel reports a BUG_ON(slot == NULL) in radix_tree_tag_set() on s390 3.0.13: called from __set_page_dirty_nobuffers() when page_remove_rmap() tries to transfer dirty flag from s390 storage key to struct page and radix_tree. That would be because of reclaim's shrink_page_list() calling add_to_swap() on this page at the same time: first PageSwapCache is set (causing page_mapping(page) to appear as &swapper_space), then page->private set, then tree_lock taken, then page inserted into radix_tree - so there's an interval before taking the lock when the radix_tree slot is empty. We could fix this by moving __add_to_swap_cache()'s spin_lock_irq up before the SetPageSwapCache. But a better fix is simply to do what's five years overdue: Ken Chen introduced __set_page_dirty_no_writeback() (if !PageDirty TestSetPageDirty) for tmpfs to skip all the radix_tree overhead, and swap is just the same - it ignores the radix_tree tag, and does not participate in dirty page accounting, so should be using __set_page_dirty_no_writeback() too. s390 testing now confirms that this does indeed fix the problem.

commit c744a65c md: don't set md arrays to readonly on shutdown. removed the possibility of a 'BUG' when data is written to an array that has just been switched to read-only, but also introduced the possibility that the array metadata could be corrupted. If, when md_notify_reboot gets the mddev lock, the array is in a state where it is assembled but hasn't been started (as can happen if the personality module is not available, or in other unusual situations), then incorrect metadata will be written out making it impossible to re-assemble the array. So only call __md_stop_writes() if the array has actually been activated. This patch is needed for any stable kernel which has had the above commit applied.

Commit 7bfec5f3 md/raid5: If there is a spare and a want_replacement device, start replacement. cause md_check_recovery to call ->add_disk much more often. Instead of only when the array is degraded, it is now called whenever md_check_recovery finds anything useful to do, which includes updating the metadata for clean<->dirty transition. This causes unnecessary work, and causes info messages from ->add_disk to be reported much too often. So refine md_check_recovery to only do any actual recovery checking (including ->add_disk) if MD_RECOVERY_NEEDED is set.

This gets rid of the unused default senses array, and replaces the incorrect use of IRQ_TYPE_NONE with the new IRQ_TYPE_DEFAULT for the initial set_trigger() call when mapping an interrupt. This in turn makes us read the HW state and update the irq desc accordingly. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This is meant typically to allow a PIC driver's irq domain map() callback to establish sane defaults for the interrupt (and make sure that the HW and the irq_desc are in sync as far as the trigger is concerned). The irq core may not call the set_trigger callback if it thinks the trigger is already set to the right setting, so we need to ensure new descriptors are properly synchronized with the hardware.

mpic_is_ipi() takes a virq and immediately converts it to a hw_irq. However, one of the two call sites calls it with a ... hw_irq. The other call site also happens to have the hw_irq at hand, so let's change it to just take that as an argument. Also change mpic_is_tm() for consistency.

If the interrupt and the timeout happen roughly at the same time, we can get into a situation where the timer function is run while the interrupt has already been processed. In this case, the timer function might end up doing an add_timer on an already pending timer, causing a BUG_ON() to trigger. Instead, just skip the whole timeout operation if we see that the timer is pending. The spinlock ensures that the only way that happens is if we already started a new operation and thus the timeout can be ignored. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The problem was reported by Anton Blanchard. While EEH error happened to the PCI device without the corresponding device driver, kernel crash was seen. Eventually, I successfully reproduced the problem on Firebird-L machine with utility "errinjct". Initially, the device driver for Emulex ethernet MAC has been disabled from .config and force data parity on the Emulex ethernet MAC with help of "errinjct". Eventually, I saw the kernel crash after issueing couple of "lspci -v" command. The root cause behind is that the PCI device, including the reference to the corresponding eeh device, will be removed from the system while EEH does recovery. Afterwards, the PCI device will be probed again and added into the system accordingly. So it's not safe to retrieve the eeh device from the corresponding PCI device after the PCI device has been removed and not added again. The patch fixes the issue and retrieve the eeh device from OF node instead of PCI device after the PCI device has been removed.
