Adds a test case for AHCI wherein we write a 4K
block of a changing pattern to sector 0, then
read back that 4K and compare the transmit and
receive buffers.

ahci_io is a wrapper around ahci_guest_io that takes a pointer to host
memory instead, and will create a guest memory buffer and copy the data
to/from as needed and as appropriate for a read/write command, such that
after a read, the guest data will be in a host buffer, and for a write,

The default is --disable-liburcu, which means QEMU's RCU
implementation is used.
When building with --enable-liburcu, the memory barrier version
of liburcu (urcu-mb) is linked against. We might want to make this
configurable in the future for greater performance; for now we just
match the liburcu
Hi Paolo + all,
First off, thanks for your ongoing RCU work, which I'm closely
following.
As you stated in the initial RCU patch (7911747b), the intent
is to keep the same API as liburcu's. I checked whether this
was the case and found a couple of issues that I'm addressing
in the appended series
The recently added call_rcu does not match liburcu's call_rcu's semantics;
instead, call_rcu1 does. Fix it by doing the following:
- Rename QEMU's call_rcu to call_rcu_first_elem
- Rename QEMU's call_rcu1 to call_rcu
The end goal is to be able to switch at compile-time between
liburcu and QEMU's
This matches the semantics of liburcu.

The series of patches adds support EEH for VFIO PCI devices on sPAPR platform.
It requires corresponding host kernel support, which was merged during 3.17
merge window. This patchset has been rebased to Alex Graf's QEMU repository:
git://github.com/agraf/qemu.git (branch: ppc-next)
The impleme
The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.
The patch defines constants used by EEH RTAS calls and adds
callback sPAPRPHBClass::eeh_handler, which is going to be used
this way:
* RTAS calls are received in spapr_pci.c, sanity check is
The patch implements sPAPRPHBClass::eeh_handler so that the
EEH RTAS requests can be routed to VFIO for further handling.
