342e313d6c exec/cpu-all: remove system/memory include
We include this header where needed. When includes set already have
ifdef CONFIG_USER_ONLY, we add it here, else, we don't condition the
include.

161f5bc8e9 include/exec: Split out icount.h
Split icount stuff from system/cpu-timers.h.
There are 17 files which only require icount.h, 7 that only
require cpu-timers.h, and 7 that require both.

105d7ea0a5 hw/xen: add stubs for various functions
Those symbols are used by system/physmem.c, and are called only if
xen_enabled() (which happens only if CONFIG_XEN is set and xen is
available).

So we can crash the stubs in case those are called, as they are linked
only when CONFIG_XEN is not set.

e28fbd1c52 Revert "virtio-net: Copy received header to buffer"
This reverts commit 7987d2be5a.

The goal was to remove the need to patch the (const) input buffer
with a recomputed UDP checksum by copying headers to a RW region and
inject the checksum there. The patch computed the checksum only from the
header fields (missing the rest of the payload) producing an invalid one
and making guests fail to acquire a DHCP lease.

segment_size is expressed in units of 512 bytes.
Given segment_size = 0x2000 (8192), the actual size is 4MB.
Similarly, allocation_unit_size = 1 means 1 segment = 4MB.

In commit 8fd2518ef2 ("hw: Centralize handling of -machine dumpdtb

machine.  This resulted in the device tree missing parts of the machine
description, depending on how they construct their device tree.

The arm virt machine is missing some PSCI nodes, while the riscv one
is missing most of its content.

Move the dump to after the notifiers have been run, allowing
virt_machine_done to be called and the device tree to be fully
populated.

61b6d9b749 scsi-disk: Apply error policy for host_status errors again
Originally, all failed SG_IO requests called scsi_handle_rw_error() to
apply the configured error policy. However, commit f3126d65, which was
supposed to be a mere refactoring for scsi-disk.c, broke this and
accidentally completed the SCSI request without considering the error
policy any more if the error was signalled in the host_status field.

Apart from the commit message not describing the change as intended,
errors indicated in host_status are also obviously backend errors and
not something the guest must deal with independently of the error
policy.

This behaviour means that some recoverable errors (such as a path error
in multipath configurations) were reported to the guest anyway, which
might not expect it and might consider its disk broken.

Make sure that we apply the error policy again for host_status errors,
too. This addresses an existing FIXME comment and allows us to remove
some comments warning that callbacks weren't always called. With this
fix, they are called in all cases again.

The return value passed to the request callback doesn't have more free
values that could be used to indicate host_status errors as well as SAM
status codes and negative errno. Store the value in the host_status
field of the SCSIRequest instead and use -ENODEV as the return value (if
a path hasn't been reachable for a while, blk_aio_ioctl() will return
-ENODEV instead of just setting host_status, so just reuse it here -
it's not necessarily entirely accurate, but it's as good as any errno).

fa0dde12db hw/loongarch/virt: Replace destination error with error_abort
In function virt_cpu_plug() and virt_cpu_unplug(), the error is
impossile. Destination error is not propagated and replaced with
error_abort. With this, the logic is simple.

988ad4cceb hw/loongarch/virt: Fix cpuslot::cpu set at last in virt_cpu_plug()
In function virt_cpu_plug(), Object cpuslot::cpu is set at last
only when there is no any error, otherwise it is problematic that
cpuslot::cpu is set in advance however it returns because of error.

719255486d hw/i386/amd_iommu: Assign pci-id 0x1419 for the AMD IOMMU device
Currently, the QEMU-emulated AMD IOMMU device use PCI vendor id 0x1022
(AMD) with device id zero (undefined). Eventhough this does not cause any
functional issue for AMD IOMMU driver since it normally uses information
in the ACPI IVRS table to probe and initialize the device per
recommendation in the AMD IOMMU specification, the device id zero causes
the Windows Device Manager utility to show the device as an unknown device.

Since Windows only recognizes AMD IOMMU device with device id 0x1419 as
listed in the machine.inf file, modify the QEMU AMD IOMMU model to use
the id 0x1419 to avoid the issue. This advertise the IOMMU as the AMD
IOMMU device for Family 15h (Models 10h-1fh).

20ab88a906 hw/misc/aspeed_scu: Correct minimum access size for AST2500 / AST2600
Guest code was performing a byte load to the SCU MMIO region, leading
to the guest code crashing (it should be using proper accessors, but
that is not Qemu's bug). Hardware and the documentation[1] both agree
that byte loads are okay, so change all of the aspeed SCU devices to
accept a minimum access size of 1.

[1] See the 'ARM Address Space Mapping' table in the ASPEED docs. This
is section 6.1 in the ast2400 and ast2700, and 7.1 in the ast2500 and
ast2600 datasheets.

All MemoryRegionOps::read/write() handlers switch over a 32-bit
aligned value, because converted using TO_REG(), which is defined
as:

  #define TO_REG(offset) ((offset) >> 2)

So all implementations are 32-bit.
Set min/max access_size accordingly.

fca2817fdc target/mips: Revert TARGET_PAGE_BITS_VARY
Revert ee3863b9d4 and a08d60bc6c.  The logic behind changing
the system page size because of what the Loongson kernel "prefers"
is flawed.

In the Loongson-2E manual, section 5.5, it is clear that the cpu
supports a 4k page size (along with many others).  Similarly for
the Loongson-3 series CPUs, the 4k page size is mentioned in the
section 7.7 (PageMask Register).  Therefore we must continue to
support a 4k page size.
