      net: smsc911x: back out silently on probe deferrals · ab4e4c07
      Linus Walleij authored
      When trying to get a regulator we may get deferred and we see
      this noise:
      smsc911x 1b800000.ethernet-ebi2 (unnamed net_device) (uninitialized):
         couldn't get regulators -517
      Then the driver continues anyway. Which means that the regulator
      may not be properly retrieved and reference counted, and may be
      switched off in case noone else is using it.
      Fix this by returning silently on deferred probe and let the
      system work it out.

      ibmveth: set correct gso_size and gso_type · 7b596738
      Thomas Falcon authored
      This patch is based on an earlier one submitted
      by Jon Maxwell with the following commit message:
      "We recently encountered a bug where a few customers using ibmveth on the
      same LPAR hit an issue where a TCP session hung when large receive was
      enabled. Closer analysis revealed that the session was stuck because the
      one side was advertising a zero window repeatedly.
      We narrowed this down to the fact the ibmveth driver did not set gso_size
      which is translated by TCP into the MSS later up the stack. The MSS is
      used to calculate the TCP window size and as that was abnormally large,
      it was calculating a zero window, even although the sockets receive buffer
      was completely empty."
      We rely on the Virtual I/O Server partition in a pseries
      environment to provide the MSS through the TCP header checksum
      field. The stipulation is that users should not disable checksum
      offloading if rx packet aggregation is enabled through VIOS.
      Some firmware offerings provide the MSS in the RX buffer.
      This is signalled by a bit in the RX queue descriptor.

      Pull parisc fixes from Helge Deller:
       "Three important fixes for the parisc architecture.
        Dave provided two patches: One which purges the TLB before setting a
        PTE entry and a second one which drops unnecessary TLB flushes. Both
        patches have been tested for one week on the debian buildd servers and
        prevent random segmentation faults.
        The patch from me fixes a crash at boot inside the TLB measuring code
        on SMP machines with PA8000-PA8700 CPUs (specifically A500-44 and
        J5000 servers)"

      parisc: Fix TLB related boot crash on SMP machines · 24d0492b
      Helge Deller authored
      At bootup we run measurements to calculate the best threshold for when we
      should be using full TLB flushes instead of just flushing a specific amount of
      TLB entries.  This performance test is run over the kernel text segment.
      But running this TLB performance test on the kernel text segment turned out to
      crash some SMP machines when the kernel text pages were mapped as huge pages.
      To avoid those crashes this patch simply skips this test on some SMP machines
      and calculates an optimal threshold based on the maximum number of available
      TLB entries and number of online CPUs.
      On a technical side, this seems to happen:
      The TLB measurement code uses flush_tlb_kernel_range() to flush specific TLB
      entries with a page size of 4k (pdtlb 0(sr1,addr)). On UP systems this purge
      instruction seems to work without problems even if the pages were mapped as
      huge pages.  But on SMP systems the TLB purge instruction is broadcasted to
      other CPUs. Those CPUs then crash the machine because the page size is not as
      expected.  C8000 machines with PA8800/PA8900 CPUs were not affected by this
      problem, because the required cache coherency prohibits to use huge pages at
      all.  Sadly I didn't found any documentation about this behaviour, so this
      finding is purely based on testing with phyiscal SMP machines (A500-44 and
      J5000, both were 2-way boxes).
