      [PATCH] ppc64: Add a sync in context switch on SMP · 0ef9775d
      Benjamin Herrenschmidt authored
      For the same reason as ppc32, we need to ensure that all stores
      done on a CPU has reached the coherency domain and are visible
      to loads done by another CPU when context switching as the same
      thread may be rescheduled almost right away there.

      [PATCH] ppc32: PCI mmap update · 585d744b
      Benjamin Herrenschmidt authored
      This updates the ppc32 PCI mmap facility to allow mmap'ing of space
      outside of the actual devices, using the host bridge resources instead. 
      
      This allow userland to map things like legacy IO space by either using
      the bridge device itself, or simply any PCI device on the same bus
      domain

      [PATCH] ppc32: Allow PREEMPT with SMP in KConfig · f2c371c7
      Benjamin Herrenschmidt authored
      On ppc32, CONFIG_PREEMPT wasn't settable along with CONFIG_SMP
      for historical reasons (smp_processor_id() races). Those races have
      been fixes since then (well, should have been at least) so it's now
      safe to allow both options.

      [PATCH] ppc32: context switch fixes · ae4e82bd
      Benjamin Herrenschmidt authored
      This fixes a few issues with context switch on ppc32:
      
       - Makes sure we properly flush out all stores to the coherency domain
         when switching out, since the same thread could be switched back in
         on another CPU right away, those stores must be visible to all other
         CPUs. 
      
       - Remove dssall in the assembly calls and do it now once in switch_mm
         (stop vmx streams).  Assume the G5 doesn't need a sync after dssall. 
      
       - Remove bogus isync in the loop setting the userland segment registers
      
       - Do not switch the userland segments when the mm stays the same

      [PATCH] ppc32: Even more preempt fixes · f9f57267
      Benjamin Herrenschmidt authored
      Add a warning if enable_kernel_{fp,altivec} is called with preempt
      enabled since this is always an error, and make sure the alignement
      exception handler properly disables preempt when doing FP operations.

      [PATCH] Make pdflush run at nice 0 · 6e7bbc73
      Andrew Morton authored
      Since pdflush was converted to be launched by the kthread infrastructure it
      has inherited keventd's `nice -10' setting.  That hurts interactivity when
      pdflush is doing lots of work writing back through the dm-crypt layer.
      
      So set pdflush back to `nice 0'.

      [PATCH] catch errors when completing bio pairs · ca6530ab
      Andrew Morton authored
      From: Mike Christie <michaelc@cs.wisc.edu>
      
      A couple of drivers can sometimes fail the first segments in a bio then
      requeue the rest of the request.  In this situation, if the last part of
      the bio completes successfully bio_pair_end_* will miss that the beginging
      of the bio had failed becuase they just return one when bi_size is not yet
      zero.  The attached patch moves the error value test before the bi_size to
      catch the above case.

      If a MODE_SENSE(6) command is sent to an IDE cd using the CDROM_SEND_PACKET
      ioctl, then the kernel freezes solidly. To reproduce this, one can take the
      SCSI cmd [1a 08 31 00 10 00] and a 16 byte data buffer.
      
      After some bug hunting, I found out that the following is what happens:
      
      - ide-cd recognizes that MODE_SENSE(6) isn't supported and tries
        to abort the request from ide_cdrom_prep_pc by returning BLKPREP_KILL.
      
      - in elv_next_request(), the kill request is handled by
        the following code:
      
      	while (end_that_request_first(rq, 0, rq->nr_sectors))
      		;
      	end_that_request_last(rq);
      
      The while loop never exits. The end_that_request_first() doesn't do anything
      since rq->nr_sectors is 0; it just returns "not-done" after handling those 0
      bytes (rq->bio->bi_size is 16).

      [ARM] Clean up coherent DMA allocator from previous changes. · b9ed68e3
      Russell King authored
      - Since the coherent DMA allocator is not currently compatible with
        HUGETLB, ensure that we fail at compile time should this option be
        selected.
      - Move struct device/dma mask handling into consistent_alloc().
      - Complain if someone tries to allocate coherent memory larger than
        their DMA mask will permit.
      - Rename consistent_alloc() to __dma_alloc() to ensure that there
        is no confusion that consistent_alloc() has gone.
      - Ensure warnings and errors report the correct function name.

      Since we've eliminated users of these functions, we can unexport

      [PATCH] inode dirtying timestamp fix · 18ccf569
      Andrew Morton authored
      It's a bit late in 2.6.5-rc for this, but it does fix a significant bug: for
      the first five minutes after boot, prior to the jiffy wrap, /bin/sync doesn't
      write all of the dirty data.
      
      We currently record an inode's time-of-first-dirtying in the address_space.
      This causes a few problems with dirty block special inodes: when the device
      node for /dev/hda1 needs to be written back we bogusly inspect the timestamp
      for the address_space, which belongs to a different inode.
      
      So move the inode's dirtying time up into the inode itself.
      
      This means that for block-special inodes, inode->dirtied_when represents the
      time at which the inode itself was dirtied.
      
      For regular files it represents the time at which the inode or its pages were
      dirtied.
      
      For blockdevs, the time-of-first-dirtying is recorded in the kernel-internal
      blockdev inode.  Only I_DIRTY_PAGES makes sense on these inodes.
      
      The reason all this works is that when dirtying a page we always run
      
      	__mark_inode_dirty(page->mapping->host);
      
      which refers to the kernel-internal blockdev inode.
