ppc64_boot_msg is meant to be a boot debug aid, but
is only used in one spot. Get rid of it, and save
ourseleves a couple of lines in the kernel log
buffer.

We have an extra level of indirection on memory hot remove which is not
matched on memory hot add. Memory hotplug is book3s only, so there is
no need for it.
This also enables means remove_memory() (ie memory hot unplug) works
on powernv.

Newer POWER designs do not implement PCI I/O space, so we
expect to see a number of these.
Reduce the severity of the warning so it doesn't mask other

Hi,
Please find the 9th revision of my patchset to remove
get_unused_fd() macro.
In linux-next, tag next-20141013, they're currently:
- 33 calls to fd_install()
with one call part of anon_inode_getfd()
- 27 calls to get_unused_fd_flags()
with one call part of anon_inode_
This patch replaces calls to get_unused_fd() with equivalent call to
get_unused_fd_flags(0) to preserve current behavor for existing code.
In a further patch, get_unused_fd() will be removed so that new code
start using get_unused_fd_flags(), with the hope O_CLOEXEC could be
used, either by defaul

Now that we have all implementations of ppc_md.power_off converted to

While at it, also set the default for pm_power_off to NULL so that non

The pm_power_off callback is what drivers are supposed to modify when they
implement power off support for the system.
Support a modified callback on powerpc. That way power off support code can

The generic Linux framework to power off the machine is a function pointer
called pm_power_off. The trick about this pointer is that device drivers can
potentially implement it rather than board files.
Today on PowerPC we set pm_power_off to invoke our generic full machine power
off logic which th
Xmon can manually turn off the machine. We now have 2 code paths for this:
1) ppc_md.power_off
2) pm_power_off
This patch allows xmon to support both and makes sure it graciously allows
a path to not be implemented.

If a function calls __get_SP() and later calls a function that is
tail call optimised, we will pop the stack
