After commit 9630bdd9
(ACPI: Use GPE reference counting to support shared GPEs) the wakeup
enable mask bits of GPEs are set as soon as the GPEs are enabled to
wake up the system.  Unfortunately, this leads to a regression
reported by Michal Hocko, where a system is woken up from ACPI S5 by
a device that is not supposed to do that, because the wakeup enable
mask bit of this device's GPE is always set when
acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(),
although it should only be set if the device is supposed to wake up
the system from the target state.

To work around this issue, rework the ACPI power management code so
that GPEs are not enabled to wake up the system upfront, but only
during a system state transition when the target state of the system
is known.  [Of course, this means that the reference counting of
"wakeup" GPEs doesn't really make sense and it is sufficient to
set/unset the wakeup mask bits for them during system sleep
transitions.  This will allow us to simplify the GPE handling code
quite a bit, but that change is too intrusive for 2.6.35.]

When going to standby mode mpc code maps the whole soc5200 node
to access warious MBAR registers. However as of_iomap uses 'reg'
property of device node, only small part of MBAR is getting mapped.
Thus pm code gets oops when trying to access high parts of MBAR.
As a way to overcome this, make mpc52xx_pm_prepare() explicitly
map whole MBAR (0xc0000).

In the commit below the version string handling was modified, adding
a '+' where no other version information was supplied:

    commit 85a256d8
    Author: David Rientjes <rientjes@google.com>
    Date:   Wed Jan 13 13:01:05 2010 -0800

From the commit the intent was as below:

     - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the
       repository has been revised beyond a tagged commit and LOCALVERSION=
       was not passed to "make".

However if the user supplies an empty LOCALVERSION on the command line
the plus suffix is still added.  This form is useful in the case where
the build environment knows that the version as specified is correct and
complete but does not correspond to a specific tag.

This patch changes the implementation to match the documentation
such that specifying LOCALVERSION= on the build line is sufficient
to suppress any suffix.

When trying to flash a machine via the update_flash command, Anton received the
following error:

    Restarting system.
    FLASH: kernel bug...flash list header addr above 4GB

The code in question has a comment that the flash list should be in
the kernel data and therefore under 4GB:

        /* NOTE: the "first" block list is a global var with no data
         * blocks in the kernel data segment.  We do this because
         * we want to ensure this block_list addr is under 4GB.
         */

Unfortunately the Kconfig option is marked tristate which means the variable
may not be in the kernel data and could be above 4GB.

Instead of relying on the data segment being below 4GB, use the static
data buffer allocated by the kernel for use by rtas.  Since we don't
use the header struct directly anymore, convert it to a simple pointer.

We are seeing boot fails on some System p machines when using the kdump
crashkernel= boot option. The default kdump base address is 32MB, so if we
reserve 256MB for kdump then we reserve all of the RMO except the first 32MB.

We really want kdump to reserve some memory in the RMO and most of it
elsewhere but that will require more significant changes. For now we can shift
the default base address to 64MB when CONFIG_PPC64 and CONFIG_RELOCATABLE are
set. This isn't quite correct since what we really care about is the kdump
kernel is relocatable, but we already make the assumption that base kernel
and kdump kernel have the same CONFIG_RELOCATABLE setting, eg:

#ifndef CONFIG_RELOCATABLE
        if (crashk_res.start != KDUMP_KERNELBASE)
                printk("Crash kernel location must be 0x%x\n",
                                KDUMP_KERNELBASE);
...

RTAS is instantiated towards the top of our RMO, so if we were to go any
higher we risk not having enough RMO memory for the kdump kernel on boxes
with a 128MB RMO.

The sysfs interface allowing user space to disable/enable GPEs
doesn't work correctly, because a GPE disabled this way will be
re-enabled shortly by acpi_ev_asynch_enable_gpe() if it was
previosuly enabled by acpi_enable_gpe() (in which case the
corresponding bit in its enable register's enable_for_run mask is
set).

To address this issue make the sysfs GPE interface use
acpi_enable_gpe() and acpi_disable_gpe() instead of acpi_set_gpe()
so that GPE reference counters are modified by it along with the
values of GPE enable registers.
