There are several places in spapr_hcall.c where we need to update the LPCR
value on all CPUs. We do this with the set_spr() helper. That's not
really correct because this directly sets the SPR value, without going
through the ppc_store_lpcr() helper which may need to update state based
on the LPC
Under PAPR, only the boot CPU is active when the system starts. Other cpus
must be explicitly activated using an RTAS call. The entry state for the
boot and secondary cpus isn't identical, but it has some things in common.
We're going to add a bit more common setup later, too, so to simplify
make

There are some fields in the cpu state which need to be updated when the
LPCR register is changed, which is done by ppc_hash64_update_rmls() and
ppc_hash64_update_vrma(). Code which alters env->spr[SPR_LPCR] needs to
call them afterwards to make sure the state is up to date.
That's easy to get wr

This makes several minor cleanups to these functions:
* Follow usual convention of an early exit on error, rather than having
most of the body in an if
* Clearer naming of cpu and cpu_. Now callcpu is the cpu from which the
RTAS call is invoked, newcpu is the cpu which we're starting

rtas_start_cpu() calls spapr_cpu_update_tb_offset() and
spapr_cpu_set_endianness() to initialize certain things in the new cpu's
state. This is the only caller of those helpers, and they're each only
a few lines long, so we might as well just fold them into the caller.
In addition, those helpers
usb-host emulates a device unplug after live migration, because the
device state is unknown and unplug/replug makes sure the guest
re-initializes the device into a working state. This can't be done in
post-load though, so post-load just schedules a bottom half which
executes after vmload is comple
