      IB/mthca: Simplify use of size0 in work request posting · 43509d1f
      由 Roland Dreier 提交于 
          
Current code sets size0 to 0 at the start of work request posting
functions and then handles size0 == 0 specially within the loop over
work requests.  Change this so size0 is set along with f0 the first
time through the loop (when nreq == 0).  This makes the code easier to
understand by making it clearer that f0 and size0 are always
initialized if nreq != 0 without having to know that size0 == 0
implies nreq == 0.

Also annotate size0 with uninitialized_var() so that this doesn't
introduce a new compiler warning.

      IB/mthca: Factor out setting WQE UD segment entries · e535c699
      由 Roland Dreier 提交于 
          
Factor code to set UD entries out of the work request posting
functions into inline functions set_tavor_ud_seg() and
set_arbel_ud_seg().  This doesn't change the generated code in any
significant way, and makes the source easier on the eyes.

      IB/mlx4: Factor out setting other WQE segments · 0fbfa6a9
      由 Roland Dreier 提交于 
      Factor code to set remote address, atomic and datagram segments out of
mlx4_ib_post_send() into small helper functions.  This doesn't change
the generated code in any significant way, and makes the source easier
on the eyes.

      PCI: Change all drivers to use pci_device->revision · 44c10138
      由 Auke Kok 提交于 
      Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.
