[Qemu-devel] [PULL 2.3 2/5] spapr: Add missing checks for NULL pointers and report failures

[Alexander Graf]

From: Stefan Weil <sw@weilnetz.de>

This fixes potential runtime crashes and two warnings from Coverity.

The new error message does not add  a prefix "qemu:" because that is
already done in function hw_error. It also starts with an uppercase
letter because that seems to be the mostly used form.

[Qemu-devel] [PULL 2.3 3/5] target-ppc: Remove POWER5+ v0.0 that never existed

[Alexander Graf]

From: Alexey Kardashevskiy <aik@ozlabs.ru>

IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B0000.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.

This removes CPU_POWERPC_POWER5P_v00 definition and changes
POWER5+ and POWERgs aliases (which are synonyms) to point to
POWER5+_v2.1 which can still be found in real machines.

[Qemu-devel] [PULL 2.3 4/5] PPC: pseries: Implement boot once=foo

[Alexander Graf]

On sPAPR we haven't supported boot once ever since it emerged, but
recently grew need for it. This patch implements boot once logic
to it.

While at it, we also move to the new bootdevice handling that got
introduced to the tree recently.

[Qemu-devel] [PULL 2.3 5/5] powerpc: fix -machine usb=no for newworld and pseries machines

[Alexander Graf]

From: Paolo Bonzini <pbonzini@redhat.com>

Capture the explicit setting of "usb=no" into a separate bool, and
use it to skip the update of machine->usb in the board init function.
