      parisc: perf: return -EFAULT on error · 82cbd568
      Dan Carpenter authored
      The copy_from_user() returns the number of bytes remaining to be copied
      but we want to return -EFAULT if it's non-zero.

      parisc: Enhance CPU detection code on PAT machines · 637250cc
      Helge Deller authored
      This patch fixes the debug code which runs during the inventory scan on
      machines with PAT firmware.
      
      Additionally print out the relationship between the detected logical CPU
      number and it's physical location and physical cpu number.
      This leads to information which can be used to feed numa-structures in
      the kernel in later patches. An example output is from my single-CPU (2
      cores) C8000 machine is:
      
        Logical CPU #0 is physical cpu #0 at 0xffff0000ffff15, hpa 0xfffffffffe780000
        Logical CPU #1 is physical cpu #1 at 0xffff0000ffff15, hpa 0xfffffffffe781000

      parisc: Re-enable interrupts early · 5c38602d
      Helge Deller authored
      Since kernel 3.9 we re-enable interrupts quite late due to commit c207a76b
      ("parisc: only re-enable interrupts if we need to schedule or deliver signals
      when returning to userspace"). At that time the parisc kernel had no dedicated
      IRQ stack, and this commit prevented kernel stack overflows.
      
      But since commit 200c8804 ("parisc: implement irq stacks") we now have an
      IRQ stack, so we may be safe now.  And when CONFIG_DEBUG_STACKOVERFLOW=y is
      enabled, we can even check at runtime for overflows.

      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.
