      DMA-API: net: brocade/bna/bnad.c: fix 32-bit DMA mask handling · 3e548079
      Russell King authored
      The fallback to 32-bit DMA mask is rather odd:
      	if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) &&
      	    !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) {
      		*using_dac = true;
      	} else {
      		err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32));
      		if (err) {
      			err = dma_set_coherent_mask(&pdev->dev,
      						    DMA_BIT_MASK(32));
      			if (err)
      				goto release_regions;
      		}
      
      This means we only try and set the coherent DMA mask if we failed to
      set a 32-bit DMA mask, and only if both fail do we fail the driver.
      Adjust this so that if either setting fails, we fail the driver - and
      thereby end up properly setting both the DMA mask and the coherent
      DMA mask in the fallback case.

      DMA-API: provide a helper to set both DMA and coherent DMA masks · 4aa806b7
      Russell King authored
      Provide a helper to set both the DMA and coherent DMA masks to the
      same value - this avoids duplicated code in a number of drivers,
      sometimes with buggy error handling, and also allows us identify
      which drivers do things differently.

      partitions/efi: loosen check fot pmbr size in lba · 6b02fa59
      Davidlohr Bueso authored
      Matt found that commit 27a7c642 ("partitions/efi: account for pmbr
      size in lba") caused his GPT formatted eMMC device not to boot.  The
      reason is that this commit enforced Linux to always check the lesser of
      the whole disk or 2Tib for the pMBR size in LBA.  While most disk
      partitioning tools out there create a pMBR with these characteristics,
      Microsoft does not, as it always sets the entry to the maximum 32-bit
      limitation - even though a drive may be smaller than that[1].
      
      Loosen this check and only verify that the size is either the whole disk
      or 0xFFFFFFFF.  No tool in its right mind would set it to any value
      other than these.

      cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscache · 466bd31b
      Sachin Prabhu authored
      When reading a single page with cifs_readpage(), we make a call to
      fscache_read_or_alloc_page() which once done, asynchronously calls
      the completion function cifs_readpage_from_fscache_complete(). This
      completion function unlocks the page once it has been populated from
      cache. The module then attempts to unlock the page a second time in
      cifs_readpage() which leads to warning messages.
      
      In case of a successful call to fscache_read_or_alloc_page() we should skip
      the second unlock_page() since this will be called by the
      cifs_readpage_from_fscache_complete() once the page has been populated by
      fscache.
      
      With the modifications to cifs_readpage_worker(), we will need to re-grab the
      page lock in cifs_write_begin().
      
      The problem was first noticed when testing new fscache patches for cifs.

      Sachin Prabhu authored
      We do not need to take a reference to the pagecache in
      cifs_readpage_worker() since the calling function will have already
      taken one before passing the pointer to the page as an argument to the
      function.
