There are other patches that I haven't merged because they were already
in -next. In fact I think I dropped them because they later popped up
in -next.

Some or all of:

lib-spinlock_debugc-prevent-an-infinite-recursive-cycle-in-spin_dump.patch
mm-provide-debug_pagealloc_enabled-without-config_debug_pagealloc.patch
x86-query-dynamic-debug_pagealloc-setting.patch
s390-query-dynamic-debug_pagealloc-setting.patch
mm-provide-debug_pagealloc_enabled-without-config_debug_pagealloc.patch
x86-query-dynamic-debug_pagealloc-setting.patch
s390-query-dynamic-debug_pagealloc-setting.patch

So please resend everything which you think is needed.
