      RDMA/cxgb4: Only allow kernel db ringing for T4 devs · c2f9da92
      由 Steve Wise 提交于 
      The whole db drop avoidance stuff is for T4 only.  So we cannot allow
that to be enabled for T5 devices.

      RDMA/cxgb4: Fix endpoint mutex deadlocks · cc18b939
      由 Steve Wise 提交于 
      In cases where the cm calls c4iw_modify_rc_qp() with the endpoint
mutex held, they must be called with internal == 1.  rx_data() and
process_mpa_reply() are not doing this.  This causes a deadlock
because c4iw_modify_rc_qp() might call c4iw_ep_disconnect() in some
!internal cases, and c4iw_ep_disconnect() acquires the endpoint mutex.
The design was intended to only do the disconnect for !internal calls.

Change rx_data(), FPDU_MODE case, to call c4iw_modify_rc_qp() with
internal == 1, and then disconnect only after releasing the mutex.

Change process_mpa_reply() to call c4iw_modify_rc_qp(TERMINATE) with
internal == 1 and set a new attr flag telling it to send a TERMINATE
message.  Previously this was implied by !internal.

Change process_mpa_reply() to return whether the caller should
disconnect after releasing the endpoint mutex.  Now rx_data() will do
the disconnect in the cases where process_mpa_reply() wants to
disconnect after the TERMINATE is sent.

Change c4iw_modify_rc_qp() RTS->TERM to only disconnect if !internal,
and to send a TERMINATE message if attrs->send_term is 1.

Change abort_connection() to not aquire the ep mutex for setting the
state, and make all calls to abort_connection() do so with the mutex
held.

      Merge tag 'trace-fixes-v3.15-rc2' of... · 2aafe1a4
      由 Linus Torvalds 提交于 
      Merge tag 'trace-fixes-v3.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull ftrace bugfix from Steven Rostedt:
 "Takao Indoh reported that he was able to cause a ftrace bug while
  loading a module and enabling function tracing at the same time.

  He uncovered a race where the module when loaded will convert the
  calls to mcount into nops, and expects the module's text to be RW.
  But when function tracing is enabled, it will convert all kernel text
  (core and module) from RO to RW to convert the nops to calls to ftrace
  to record the function.  After the convertion, it will convert all the
  text back from RW to RO.

  The issue is, it will also convert the module's text that is loading.
  If it converts it to RO before ftrace does its conversion, it will
  cause ftrace to fail and require a reboot to fix it again.

  This patch moves the ftrace module update that converts calls to
  mcount into nops to be done when the module state is still
  MODULE_STATE_UNFORMED.  This will ignore the module when the text is
  being converted from RW back to RO"

      由 Linus Torvalds 提交于 
      Pull devicetree bug fixes from Grant Likely:
 "These are some important bug fixes that need to get into v3.15.

  This branch contains a pair of important bug fixes for the DT code:

   - Fix some incorrect binding property names before they enter common
     usage

   - Fix bug where some platform devices will be unable to get their
     interrupt number when they depend on an interrupt controller that
     is not available at device creation time.  This is a problem
     causing mainline to fail on a number of ARM platforms"
