We have smp_ops->cpu_die() and ppc_md.cpu_die(). One of them offlines
the current CPU and one offlines another CPU, can you guess which is
which? Also one is in smp_ops and one is in ppc_md?
So rename ppc_md.cpu_die(), to cpu_offline_self(), because that's what
it does. And move it into smp_ops wh
Avoid the eternal confusion between cpu_die() and __cpu_die() by
removing the former, folding it into its only caller.

arch_cpu_idle_dead() is in idle.c, which makes sense, but it's inside
a CONFIG_HOTPLUG_CPU block.
It would be more at home in smp.c, inside the existing
CONFIG_HOTPLUG_CPU block. Note that CONFIG_HOTPLUG_CPU depends on
CONFIG_SMP so even though smp.c is not built for SMP=n builds, that's
fine.

The last caller was removed in 2014 in commit fb5a515704d7 ("powerpc:
Remove platforms/wsp and associated pieces").
As Jordan noticed even though there are no callers, the code above in
fsl_secondary_thread_init() falls through into
generic_secondary_thread_init(). So we can remove the _GLOBAL but
These platforms don't show the MMU in /proc/cpuinfo, but they always

This version of set_dscr() was added for the RFI flush test, and is

If we're running on a CPU without VMX/VSX then don't touch them. This
is fragile, the compiler could spill a VMX/VSX register and break the
test anyway. But in practice it seems to work, ie. the test runs to
completion on a system without VSX with this change.

On older CPUs the switch_endian() syscall doesn't work. Currently that
causes the switch_endian_test to just crash. Instead detect the

The error messages in the changed functions are exactly the same.
In order to differentiate them and make debugging easier,

When H_SEND_CRQ command returns with H_CLOSED, it means the
server's CRQ is not ready yet. Instead of resetting immediately,
we wait for the server to launch passive init.
ibmvnic_init() and ibmvnic_reset_init() should also return the
error code from ibmvnic_send_crq_init() call.

At the beginning of the function, from_passive_init is set false by
"adapter->from_passive_init = false;",
hence the if statement will never run.

These two functions share the majority of the code, hence merge
them together. In the meanwhile, add a reset pass-in parameter
to differentiate them. Thus, the code is easier to read and to tell
the difference between reset_init and regular init.
