      [PATCH] ia64: Avoid deadlock when using printk() for MCA and INIT records · 472bf5ab
      Keith Owens authored
      Port the ia64 mca.c clean up patches from 2.4.25-pre8 to 2.6.2-rc2.
      
      The following 6 patches do :-
      
      1 Avoid deadlock when using printk() for MCA and INIT records.
      2 Delete all record printing code, moved to salinfo_decode in user space.
      3 Mark variables and functions static where possible.
      4 Delete dead variables and functions.
      5 Reorder to remove the need for forward declarations and to consolidate
        related code.
      6 Bjorn's printk cleanup.
      
      Altogether they shrink mca.c from 2432 to 1339 lines and make it much
      more readable.
      
      The only functional change is the removal of any attempt to print the
      CMC/CPE/MCA/INIT record contents in the kernel plus the addition of an
      info printk to ia64_mca_check_errors(), to match 2.4.  Now we just get
      one line to say that a record has been detected, except for MCA which
      prints nothing at all.

      [PATCH] ia64: sba_iommu perf tunning and new functionality · 6898da46
      Alex Williamson authored
         I've been doing some performance tuning and adding some functionality
      to sba_iommu for zx1/sx1000 chipsets.  This adds:
      
            * Long overdue consistent_dma_mask support
            * Long overdue ability to do large mappings in the iommu
            * Tightened spinlock usage for better performance/scalability
            * Added branch prediction hints for some of the performance paths
            * Added explicit data prefetching to some performance paths -
              perfmon shows roughly a 20% decrease in L3 misses in the bitmap
              search code
            * Increased delayed resource freeing depth and added a separate
              lock per ioc to avoid contention
            * Added code to free up queued pdir entries should we be unable to
              find space for new ones (not that I've ever seen the pdir
              anywhere close to full)
            * Finished cleaning out the hint support code, Grant is
              maintaining this separately for now
            * Added option to control bypass of sg mappings separately from
              single/coherent mappings
      
      Much like the swiotlb, sba_iommu allows devices capable of 64bit
      addressing to bypass the iommu and DMA directly to/from memory.  Using a
      worst case scenario test (64bit bypass disabled, all DMA mapped through
      the iommu), I saw a 60% increase in sequential block input throughput
      using bonnie++ on a large RAID0 MD array.  In fact, this patch provides
      the best bonnie++ performance with bypass disabled.  This is likely due
      to benefits seen from coalescing the scatterlist, allowing better disk
      streaming.  I assume that network performance will likely be limited by
      mapping latency, so I added the last bullet item to allow sg mappings to
      get the benefit of coalescing while keeping a low latency path for
      single and coherent mappings.  If anyone is setup for network
      benchmarks, I'd be interested in a before and after with this patch.

      [PATCH] ia64: fix ld.a emulation · 0f227137
      Kenneth W. Chen authored
      This patch fixes a corner-case of ld.a emulation.  ld.a should be
      emulated such that it always loads a misaligned value and clears the
      corresponding ALAT entry.  The old emulation was correct for the case
      where ld.a was followed by ld.c/chk.a (since ALAT entry was cleared),
      but wrong for the case where it _wasn't_ followed by ld.c/chk.a.  In
      that case, the misaligned value wasn't read from memory, as it should
      have been.

      [PATCH] dm: block size bug with 64 bit devs · 92155747
      Joe Thornber authored
      With 32 bit sector_t the block device size _in bytes_ is also cut to
      32 bit in __set_size when the block device is mount (a filesystem
      mounted). The argument should be cast to loff_t before expanding the
      sector count to a byte count and calling i_size_write.

      [PATCH] DVD-R capability flag set incorrectly, /proc formatting fix · 1ec2fc7d
      Jens Axboe authored
      From John McKell <mckellj@iomega.com>:
      
        This patch for scsi/sr.c and cdrom/cdrom.c persuades
        /proc/sys/dev/cdrom/info to report that connecting a drive via USB
        rather than ATAPI in fact does not make it able to write DVD-R.
      
        Without this patch, when sr0 and hdd are the same type of device
        connected via USB and ATAPI respectively, I see:
      
      	$ cat /proc/sys/dev/cdrom/info:
      	drive name:             sr1     sr0     hdd
      	...
      	Can write CD-R:         1       0       0
      	Can write CD-RW:        1       0       0
      	Can read DVD:           0       0       0
      	Can write DVD-R:        1       1       0
      	Can write DVD-RAM:      0       0       0
      	Can read MRW:           0               0               0
      	Can write MRW:          0               0               0
      
        With this patch applied, instead I see:
      
      	$ cat /proc/sys/dev/cdrom/info:
      	drive name:             sr1     sr0     hdd
      	...
      	Can write CD-R:         1       0       0
      	Can write CD-RW:        1       0       0
      	Can read DVD:           0       0       0
      	Can write DVD-R:        0       0       0
      	Can write DVD-RAM:      0       0       0
      	Can read MRW:           0       0       0
      	Can write MRW:          0       0       0
      
        The sr1 device in particular is an ordinary CD-RW that in fact cannot
        write DVD-R.
      
        While messing with this code, I also thought to tweak the /proc
        formatting to align the tabbed columns.

      [PATCH] Export OF device path for PCI devices · af3ad153
      Benjamin Herrenschmidt authored
      Here's a new version of the patch according to our discussion.
      
      This allows the platform to add its own platform files to the
      sysfs PCI device node through a "pcibios_add_platform_entries()"
      call.
      
      I added an empty pcibios_add_platform_entries() inline to all
      archs that apparently have PCI and implemented the OF stuff for
      ppc and ppc64. The name is still "devspec" for now, I doubt
      it will conflict and that's consistent with our use of the
      "devspec" name in other places.
