Hello.
The BUG_ON() check at move_freepages() is wrong.
Its end_page is start_page + MAX_ORDER_NR_PAGES. So, it can be
next zone. BUG_ON() should check "end_page - 1".
This is fix of 2.6.21-rc3-mm2 for it.

Yeah, I'm not at all surprised. Any implementation of "prefetch" that
doesn't just turn into a no-op if the TLB entry doesn't exist (which makes
them weaker for *actual* prefetching) will generally have a hard time with
a NULL pointer. Exactly b

This patch add an anonymous inode source, to be used for files that need
and inode only in order to create a file*. We do not care of having an
inode for each file, and we do not even care of having different names in
the associated dentries (dentry names will be same for classes of file*).

This patch series implements the new signalfd() and signalfd_dequeue()
system calls. I took part of the original Linus code (and you know how
badly it can be broken :), and I added even more breakage ;)
The patch had to be almost completely changed. This patch allows multiple

The basic calculation has to be done in 32 bits to avoid
doing 64 bit divide by 3. The value x is only 22bits max
so only need full 64 bits only for x^2.

Every single non-PCI controller has been broken by this code.
pata_get_dev_handle() assumes that the passed ata_port is PCI. The
libata-core code does not do any checking. This causes everyone to
experience oopses with pata_pcmcia for example.
