      [POWERPC] Update documentation for flat device tree format v17 · 0e0293c8
      由 David Gibson 提交于 
      This patch updates booting-without-of.txt to describe version 17 of
the flattened device tree format.  Version 17 is a small, backwards
compatible change from version 16, adding an extra field giving the
size of the device tree's structure block.  At this time, the kernel
has no use for the extra information, however its presence can make
life easier for bootloaders or other software manipulating the tree.

In addition this patch adds information on the size_dt_strings field
of the device tree header, present since version 3 of the flattened
tree format, but omitted from the documentation.  It also makes
changes to consistently refer to versions 16 and 17 as versions 16 and
17 in decimal, rather than version 0x10 which was occasionally used
for version 16 previously.

Finally, we also add the new field to the definition of the device
tree header structure in prom.h

      [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanup · 6bccf755
      由 Joachim Fenkes 提交于 
      This adds two sysfs attributes to /sys/bus/ibmebus which can be used to
notify the ebus driver of added / removed ebus devices in the OF device
tree.

Echoing the device's location code (as found in the OFDT "ibm,loc-code"
property) into the "probe" attribute will notify ebus of addition of the
device and cause the appropriate device driver's probe function to be called
on the device.

Likewise, echoing the location code into the "remove" attribute will cause
the device to be removed from the system.

The writes will block until the respective operation has finished and return
an error code if the operation failed.

In addition, two minor tidbits are fixed:

- The fake root device used to provide a common parent for all ebus devices
  is now based on device instead of of_device - it had no associated devtree
  node. This saves several checks throughout the ebus driver.

- The sysfs attributes are now generated automagically by device_register()
  instead of by the ibmebus code, which saves a few compiler warnings about
  unused return codes.

      [POWERPC] Fix spu SLB invalidations · 94b2a439
      由 Benjamin Herrenschmidt 提交于 
      The SPU code doesn't properly invalidate SPUs SLBs when necessary,
for example when changing a segment size from the hugetlbfs code. In
addition, it saves and restores the SLB content on context switches
which makes it harder to properly handle those invalidations.

This patch removes the saving & restoring for now, something more
efficient might be found later on. It also adds a spu_flush_all_slbs(mm)
that can be used by the core mm code to flush the SLBs of all SPEs that
are running a given mm at the time of the flush.

In order to do that, it adds a spinlock to the list of all SPEs and move
some bits & pieces from spufs to spu_base.c

      [PATCH] sched: remove SMT nice · 69f7c0a1
      由 Con Kolivas 提交于 
      Remove the SMT-nice feature which idles sibling cpus on SMT cpus to
facilitiate nice working properly where cpu power is shared.  The idling of
cpus in the presence of runnable tasks is considered too fragile, easy to
break with outside code, and the complexity of managing this system if an
architecture comes along with many logical cores sharing cpu power will be
unworkable.

Remove the associated per_cpu_gain variable in sched_domains used only by
this code.

Also:

  The reason is that with dynticks enabled, this code breaks without yet
  further tweaks so dynticks brought on the rapid demise of this code.  So
  either we tweak this code or kill it off entirely.  It was Ingo's preference
  to kill it off.  Either way this needs to happen for 2.6.21 since dynticks
  has gone in.
