During kdump we run the crash handlers first then stop all other CPUs. We really want to stop all CPUs as close to the fail as possible and also have a very controlled environment for running the crash handlers, so it makes sense to reverse the order.

Some modules (like eHCA) want to map all of kernel memory, for this to work with a relocated kernel, we need to export kernstart_addr so modules can use PHYSICAL_START and memstart_addr so they could use MEMORY_START. Note that the 32bit code already exports these symbols. Signed-off-By: Sonny Rao <sonnyrao@us.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This makes the 64-bit kernel use 64-bit signed integers for the counter (effectively supporting 32-bit of active count in the semaphore), thus avoiding things like overflow of the mmap_sem if you use a really crazy number of threads Note: Ideally the type in the structure should be atomic_long_t rather than "long". However, there's some nasty issues with that. It needs to be initialized statically -and- lib/rwsem.c does things like sem->count = RWSEM_UNLOCKED_VALUE; Now, if you mix in the fact that atomic_* types are actually structures with one member and note typedefs of a scalar, it makes its really nasty. So I stuck to what we did before using a long and casts for now. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config - I don't know. But it has silently been there until I tried 2.6.36-rc2, where it broke the build because I don't have LED support turned on. Attached patch fixes things up. (I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise I get unsightly core dumps out of scripts/kconfig/conf). jon -- toshiba: make sure we pull in LED support The Toshiba extras driver uses the LED module, so make sure we have it configure in.

It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.

Dave Chinner authored
Commit ebf8aa44 ("radix-tree: omplement function radix_tree_range_tag_if_tagged") does not safely set tags on on intermediate tree nodes. The code walks down the tree setting tags before it has fully resolved the path to the leaf under the assumption there will be a leaf slot with the tag set in the range it is searching. Unfortunately, this is not a valid assumption - we can abort after setting a tag on an intermediate node if we overrun the number of tags we are allowed to set in a batch, or stop scanning because we we have passed the last scan index before we reach a leaf slot with the tag we are searching for set. As a result, we can leave the function with tags set on intemediate nodes which can be tripped over later by tag-based lookups. The result of these stale tags is that lookup may end prematurely or livelock because the lookup cannot make progress. The fix for the problem involves reocrding the traversal path we take to the leaf nodes, and only propagating the tags back up the tree once the tag is set in the leaf node slot. We are already recording the path for efficient traversal, so there is no additional overhead to do the intermediately node tag setting in this manner. This fixes a radix tree lookup livelock triggered by the new writeback sync livelock avoidance code introduced in commit f446daae ("mm: implement writeback livelock avoidance using page tagging").

Commit f446daae ("mm: implement writeback livelock avoidance using page tagging") introduced a new radix tree tag, increasing the number of tags in each node from 2 to 3. It did not, however, fix up the code in radix_tree_node_rcu_free() that cleans up after radix_tree_shrink() and hence could leave stray tags set in the new tag array. The result is that the livelock avoidance code added in the the above commit would hit stale tags when doing tag based lookups, resulting in livelocks when trying to traverse the tree. Fix this problem in radix_tree_node_rcu_free() so it doesn't happen again in the future by using a loop to walk all the tags up to RADIX_TREE_MAX_TAGS to clear the stray tags radix_tree_shrink() leaves behind.
