cb988a10f6 hw/xen: xenpvh: Disable buffered IOREQs for ARM
Add a way to enable/disable buffered IOREQs for PVH machines
and disable them for ARM. ARM does not support buffered
IOREQ's nor the legacy way to map IOREQ info pages.

See the following for more details:

7e6b5497ea hw/char: Extract serial-mm
hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

  # grep -r -e "select SERIAL" | grep -v SERIAL_
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"
  include/hw/char/serial-mm.h:#include "hw/char/serial.h"
  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
  hw/char/serial.c:#include "hw/char/serial.h"
  hw/char/serial-isa.c:#include "hw/char/serial.h"
  hw/char/serial-pci.c:#include "hw/char/serial.h"

0701abbf98 target/i386: Expose IBPB-BRTYPE and SBPB CPUID bits to the guest
According to AMD's Speculative Return Stack Overflow whitepaper (link
below), the hypervisor should synthesize the value of IBPB_BRTYPE and
SBPB CPUID bits to the guest.

Support for this is already present in the kernel with commit
e47d86083c66 ("KVM: x86: Add SBPB support") and commit 6f0f23ef76be
("KVM: x86: Add IBPB_BRTYPE support").

Add support in QEMU to expose the bits to the guest OS.

fa9ddb1caf qemu-keymap: Release local allocation references
Commit 2523baf7fb ("qemu-keymap: Make references to allocations
static") made references to allocations static to ensure LeakSanitizer
can track them. This trick unfortunately did not work with gcc version
14.0.1; that compiler is clever enough to know that the value of the
"state" variable is only referred in the current execution of the
function and to put it on the stack.

Release references to allocations and suppress the error once for all.

7bd9b0b41d hw/audio/virtio-snd: Remove unnecessary "exec/tswap.h" header
We were including the "exec/tswap.h" header to get
target_words_bigendian() declaration, but since commit a276ec8e26
("hw/audio/virtio-snd: Always use little endian audio format")
removed this method call, we don't need this header anymore.
