      [NET]: Fix interrupt semaphore corruption in Intel drivers. · 49d85c50
      David S. Miller 提交于
      Several of the Intel ethernet drivers keep an atomic counter used to
      manage when to actually hit the hardware with a disable or an enable.
      
      The way the net_rx_work() breakout logic works during a pending
      napi_disable() is that it simply unschedules the poll even if it
      still has work.
      
      This can potentially leave interrupts disabled, but that is OK
      because all of the drivers are about to disable interrupts
      anyways in all such code paths that do a napi_disable().
      
      Unfortunately, this trips up the semaphore used here in the Intel
      drivers.  If you hit this case, when you try to bring the interface
      back up it won't enable interrupts.  A reload of the driver module
      fixes it of course.
      
      So what we do is make sure all the sequences now go:
      
      	napi_disable();
      	atomic_set(&adapter->irq_sem, 0);
      	*_irq_disable();
      
      which makes sure the counter is always in the correct state.

      PCI: Cleanup the includes of <linux/pci.h> · 6473d160
      Jean Delvare 提交于
      I noticed that many source files include <linux/pci.h> while they do
      not appear to need it. Here is an attempt to clean it all up.
      
      In order to find all possibly affected files, I searched for all
      files including <linux/pci.h> but without any other occurence of "pci"
      or "PCI". I removed the include statement from all of these, then I
      compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
      false positives manually.
      
      My tests covered 66% of the affected files, so there could be false
      positives remaining. Untested files are:

      I would welcome test reports for these files. I am fine with removing
      the untested files from the patch if the general opinion is that these
      changes aren't safe. The tested part would still be nice to have.
      
      Note that this patch depends on another header fixup patch I submitted
      to LKML yesterday:
        [PATCH] scatterlist.h needs types.h
