2014-08-01staging: lustre: bitwise vs logical typoDan Carpenter
Bitwise AND was intended here obviously. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-08-01RDMA/cxgb4: Only call CQ completion handler if it is armedSteve Wise
The function __flush_qp() always calls the ULP's CQ completion handler functions even if the CQ was not armed. This can crash the system if the function pointer is NULL. The iSER ULP behaves this way: no completion handler and never arm the CQ for notification. So now we track whether the CQ is armed at flush time and only call the completion handlers if their CQs were armed. Also, if the RCQ and SCQ are the same CQ, the completion handler is getting called twice. It should only be called once after all SQ and RQ WRs are flushed from the QP. So rearrange the logic to fix this. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

Linux doesn't run on i386, anymore. See: commit d55c5a93db2d5fa95f233ab153f594365d95b777 Author: H. Peter Anvin <hpa@linux.intel.com> Date: Wed Nov 28 11:50:24 2012 -0800 x86, 386 removal: Remove CONFIG_CMPXCHG All 486+ CPUs support CMPXCHG, so remove the fallback 386 support code. Furthermore, as the commit-message states, all 486+ CPUs support the CMPXCHG instruction and thus even legacy DRM can run fine. Drop the now superfluous "x86 == 3" check.

2014-08-01nfsd: don't destroy client if mark_client_expired_locked failsJeff Layton

A memory allocation failure could cause nfsd_startup_generic to fail, in which case nfsd_users wouldn't be incorrectly left elevated. After nfsd restarts nfsd_startup_generic will then succeed without doing anything--the first consequence is likely nfs4_start_net finding a bad laundry_wq and crashing.
