powerpc/ps3: Fix lost SMP IPIs

2011-11-21T22:35:26+00:00

commit 72f3bea075287785ed32b777b6dd2636aa7002e8 upstream.

Fixes the PS3 bootup hang introduced in 3.0-rc1 by:

  commit 317f394160e9beb97d19a84c39b7e5eb3d7815a
  sched: Move the second half of ttwu() to the remote cpu

Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi()
to ps3_get_irq() for IPI messages.

If lv1_send_event_locally() is called between a previous call to
lv1_send_event_locally() and the coresponding call to
lv1_end_of_interrupt_ext() the second event will not be delivered to the
target cpu.

The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two
IPI messages of the same type are sent to the same target in a relatively
short period of time the second IPI event can become lost when
lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

powerpc: Remove trival irq_host_ops.unmap

2011-05-19T05:31:39+00:00

These all just clear chip or chipdata fields, which will be done
by the generic code when we call irq_free_descs.

powerpc: Remove checks for MSG_ALL and MSG_ALL_BUT_SELF

2011-05-19T04:30:46+00:00

Now that smp_ops->smp_message_pass is always called with an (online) cpu
number for the target remove the checks for MSG_ALL and MSG_ALL_BUT_SELF.

powerpc: Remove ioremap_flags

2011-05-19T04:30:43+00:00

We have a confusing number of ioremap functions. Make things just a
bit simpler by merging ioremap_flags and ioremap_prot.

powerpc/ps3: Update debug message for irq_set_chip_data()

2011-04-27T04:18:39+00:00

commit ec775d0e70eb6b7116406b3441cb8501c2849dd2 ("powerpc: Convert to new irq_*
function names") changed a call from set_irq_chip_data() to
irq_set_chip_data(), but forgot to update the corresponding debug message

lmb: rename to memblock

2010-07-14T07:14:00+00:00

via following scripts

      FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

      sed -i \
        -e 's/lmb/memblock/g' \
        -e 's/LMB/MEMBLOCK/g' \
        $FILES

      for N in $(find . -name lmb.[ch]); do
        M=$(echo $N | sed 's/lmb/memblock/g')
        mv $N $M
      done

and remove some wrong change like lmbench and dlmb etc.

also move memblock.c from lib/ to mm/
