If this happens, when we load the kdump kernel we overwrite the flattened device tree, which is bad. We could make prom_init try and avoid allocating inside the crash kernel region, but then we run into issues if the crash kernel region uses all the space inside the RMO. The easiest solution is to move the flat device tree once we're running in the kernel.

This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok. (akpm: this was applied, then reverted. But it's OK now because we now use for_each_cpu() in the right places).

It looks like people have been trying to out-clever each other wrt the definition of "inline" on this architecture :), with the result that __cmpxchg(), which must be inlined so the compiler can see its argument is const, is not guaranteed to be inlined. Indeed, it was not being inlined when building with -Os. The attached patch fixes the issue by adding an __attribute__((always_inline)) explicitly to the definition of __cmpxchg() instead of relying on redefines of "inline" elsewhere to make this happen.

This uses put_page_testzero which does not handle compound pages at all. Releasing constituent pages from process mappings decrements their count to a large negative number and leaks the reference at the head page - net result is a memory leak. The problem was hidden because the debug check in put_page_testzero itself actually did take compound pages into consideration. Fix the bug and the debug check.

The patch also removes the sysfs attributes from windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm core to automagically expose attributes for sensor & controls.

Constructing ordered sequence and requeueing used to pass through __elv_add_request() which flips q->ordcolor when it sees a barrier request.
