      powerpc: Fix memory limits when starting at a non-zero address · 6dd22700
      Scott Wood authored 
      memblock_enforce_memory_limit() takes the desired maximum quantity of memory
to end up with, not an address above which memory will not be used.

      powerpc/pseries: Reduce HVCS driver insanity · c7704d35
      Benjamin Herrenschmidt authored 
      The HVCS driver, for those who don't know, is a driver for the "server" side
of the IBM virtual terminal mechanism allowing Linux partitions to act as
terminal servers under IBM PowerVM hypervisor. It's almost never used on
the field at the moment.

However, it's part of our configs, and in its current incarnation, will
allocate the tty driver & major (with 64 minors) and create a kernel thread
whether it's used or not, ie, whether the hypervisor did put a virtual
terminal server device node in the partition or not (or whether running on
a pseries machine or not even).

This in turns causes modern distro's udev's to start trying to open all
those 64 minors at boot, which, since they aren't linked to anything,
causes the driver to spew errors in the kernel log for each of them.

Not nice.

This moves all that initialization to a function which is now only called
the first time a terminal server virtual IO device is actually probed
(that is almost never).

There's still a _LOT_ of cleanup that can be done in this driver, some
simple (almost all printk's statements in there shall either just be
removed or in some case turned into better written & more informative
messages, including using the dev_* variants etc...). This is left as
an exercise for whoever actually cares about that driver.

One could also try to be smart and dispose of all the tty related
resources when the last instance of the VIO server device
is removed (Hotplug anybody ?).

      powerpc: Mask smp_processor_id() false positive · 9ff0c61d
      Paul E. McKenney authored 
      The rtas_event_scan() function uses smp_processor_id() to select a
starting point in cpu_online_mask, and does so under the protection
of get_online_cpus().  This might not select the current processor
in any case, so switch to raw_smp_processor_id().

      powerpc/macintosh: Fix __devexit annotation in rack-meter.c · e1f4dea4
      Grant Likely authored 
      The following warning was seen building rack-meter.c

WARNING: drivers/built-in.o(.text+0xac784): Section mismatch in reference from the function rackmeter_shutdown() to the function .devexit.text:rackmeter_stop_cpu_sniffer()
The function rackmeter_shutdown() references a function in an exit section.
Often the function rackmeter_stop_cpu_sniffer() has valid usage outside the exit section
and the fix is to remove the __devexit annotation of rackmeter_stop_cpu_sniffer.

This patch resolves the warning by removing the __devexit annotation from
rackmeter_stop_cpu_sniffer().
