  As part of the Linux Kernel Janitors project, I would like to submit my
  patch for bpqether.c.

  The document Documentation/cli-sti-removal.txt says that cli() should no
  longer be used to disable interrupts. This patch removes all references to
  cli() and {save,restore}_flags.

  - added a static spinlock to protect bpq_devices
  - changed cli/sti and {save,restore}_flags to taking the spinlock and
    disabling interrupts with spin_lock_irqsave
  - included my previous patch for proc_net_create, but as a separate hunk,
    so if you've already applied then just ignore the rejected hunk.

  I have verified that the patched driver compiles without warnings, but
  since I don't have the hardware I can't test it. Please treat with
  caution.
