manually and wait synchronously that each reset finished.
This patch adds the necessary infrastucture and the first exploiter of it.

Subsystems that need to add a function that needs to be called at re-IPL
may register/unregister this function via

struct reset_call {
struct reset_call *next;

- all cpus beside the current one are stopped
- all machine checks and interrupts are disabled
- prefixing is disabled
- a default machine check handler is available for use

Introduce a reset_call css_reset that does the following:
- clear all subchannels
- perform a rchp on all channel paths and wait for the resulting
  machine checks
This replaces the calls to clear_all_subchannels() and
cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
uses reipl_find_schid() to determine the subchannel id for a given

POWER5.  The patch is required to solve kdump boot issue when the
kdump kernel is booted with parameter "maxcpus=1".  XICS init code
tries to match the current boot cpu id with "reg" property in each CPU
node in the device tree.  But CPU node is created only for primary
thread CPU ids and "reg" property only reflects primary CPU ids.  So
when a kernel is booted on a secondary cpu thread above condition will
never meet and the default distribution server is left as zero.  This
leads to route the interrupts to CPU 0, but which is not online at
this time.

We use ibm,ppc-interrupt-server#s to check for both primary and
secondary CPU ids.  Accordingly default distribution server value is
initialized from "ibm,ppc-interrupt-gserver#s" property.  We loop

A few code paths need to check whether or not they are running

a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
