When we try to soft-offline a thp tail page, put_page() is called on the
tail page unthinkingly and VM_BUG_ON is triggered in put_compound_page().
This patch splits thp before going into the main body of soft-offlining.
The interface of soft-offlining is open for userspace, so this bug can
lead to

Hi,
I've hit BUG_ON(atomic_dec_and_test(&huge_zero_refcount)) in
put_huge_zero_page right now. There are some "Bad rss-counter state"

The existing code set a value in the PCI_CHANERRMSK_INT register

Avoid submitting patches to a vcc which is being closed. Things go badly
wrong when the ->pop method gets later called after everything's been
torn down.

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file

The current rules have the .dtb files build in a different directory
from the .dts files. The only reason for this is that it was what
PowerPC has done historically. This patch changes ARM to use the generic

Grant,
This breaks powerpc chroma_defconfig in next-20121127 with:

The following fixes it. The change is to generic code, so I'm not sure

So this does the same thing than thread_group_cputime(), ie: fetch the
raw cputime stats from the task/signal struct, with a two adjustment
