The RAMBlock API was dispersed in 3 different headers.
One of these headers, "exec/ram_addr.h", is restricted
to target dependent code. However these functions are
not target specific. Move all functions into a single
place. Now all these functions can be accessed by
target-agnostic code.
Move these generic functions to a more common place, with other
functions related to host page size. Document a little.

It is the job of the ppc_radix64_get_fully_qualified_addr() function
which is called at the beginning of ppc_radix64_xlate() to set both

Add 'Arm' to the Integrator/CP document title, for consistency with
the titling of the other documentation of Arm devboard models
(versatile, realview).

Sort the board index into alphabetical order. (Note that we need to
sort alphabetically by the title text of each file, which isn't the
same ordering as sorting by the filename.)

This patchset adds (minimal) documentation of these Arm board models:
vexpress-a15 ARM Versatile Express for Cortex-A15
vexpress-a9 ARM Versatile Express for Cortex-A9
mps2-an385 ARM MPS2 with AN385 FPGA image for Cortex-M35
mps2-an505 ARM MPS2 with AN505 FPGA

Same thing as the recent fix for backup, except that mirror already
forbids resizing during the job. So what remains is checking that the
sizes match at the start of the job.

Hi,
For usb device pass-through (aka -device usb-host) it would be very
useful to pass file handles from libvirt to qemu. The workflow would
change from ...
(1) libvirt enables access to /dev/usb/$bus/$dev
(2) libvirt passes $bus + $dev (using hostbus + hostaddr properties)
to qemu.

Yes. Sieger. Please install 5.0 it should work fine. I am not sure about
4.2.

Title:
Cache Layout wrong on many Zen Arch CPUs
Status in QEMU:
The other four drivers that support backing files (qcow, qcow2,
parallels, vmdk) all rely on the block layer to populate zeroes when
reading beyond EOF of a short backing file. We can simplify the qed
code by doing likewise.
