      IB/ehca: Use proper GFP_ flags for get_zeroed_page() · f2d91361
      Hoang-Nam Nguyen 提交于
      Here is a patch for ehca to use proper flag, ie. GFP_ATOMIC
      resp. GFP_KERNEL, when calling get_zeroed_page() to prevent "Bug:
      scheduling while atomic...". This error does not cause a kernel panic
      but makes ipoib un-usable afterwards.  It is reproducible on
      2.6.20-rc4 if one does ifconfig down during a flood ping test.  I have
      not observed this error in earlier releases incl. 2.6.20-rc1.
      
      This error occurs when a qp event/irq is received and ehca event
      handler allocates a control block/page to obtain HCA error data block.
      Use of GFP_ATOMIC when in interrupt context prevents this issue.
