configuration for older
machines (as it done for x86): it allows QEMU to accept incoming migration
of older pseries with or without the configuration section. So it fixes
migration from QEMU 2.3 without breaking QEMU 2.4.
---
Greg Kurz (2):
migration: allow configuration section to be optional
Use the config_section machine property to fix migration
of older pseries started with an older QEMU (version < 2.4
for both).
Older machines started with QEMU 2.4 are not affected by
this change since they send the configuration section
unconditionally.

This helper will be used to support Altivec registers in little-endian guests.
This patch does not change functionnality.
Note: I had to put the helper some lines away from the gdb_*_avr_reg()
routines to get a more readable patch.

Hi,
This series moves all the 9pfs/fsdev code to use error_report(), with the
notable exception of virtfs-proxy-helper, which doesn't need it.
Markus,
Should this patches go through your tree ? Or can they go through my 9p tree
if you ack them ?
Cheers.

This v2 does the following:
- addresses Markus Ambruster's comments for patch 1
- capitalized some messages in patch 1
- added R-b tags
I've pushed this series to my 9p-next branch.
Thanks !

This series tries to rework cross-endian helpers for better clarity.
It does not change behaviour, except perhaps patch 3/3 even if I could not
measure any performance gain.

Indeed vhost doesn't need to ask for vring endian fixing if the device is
virtio 1.0, since it is already handled by the in-kernel vhost driver. This
patch simply consolidates the logic into the existing helper.

added a runtime check for virtio 1.0, which ruins the benefit
of the virtio_access_is_big_endian() helper for always little-endian targets.
With this patch, always little-endian targets stop checking for virtio 1.0,
since the result is little-endian in all cases.

pushed the fix to
patch 1 since it is needed for the gdbstub fixes to actually work, but it
could even be handled separately.
And finally, patch 7 is Anton's + the byteswapping for little-endian
guests.
Cheers.
