Paolo Bonzini 7d37435bd5 avoid TABs in files that only contain a few
Most files that have TABs only contain a handful of them.  Change
them to spaces so that we don't confuse people.

disas, standard-headers, linux-headers and libdecnumber are imported
from other projects and probably should be exempted from the check.
Outside those, after this patch the following files still contain both
8-space and TAB sequences at the beginning of the line.  Many of them
have a majority of TABs, or were initially committed with all tabs.

Paolo Bonzini b58deb344d qemu/queue.h: leave head structs anonymous unless necessary
Most list head structs need not be given a name.  In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed.  In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct.  So clean up everything, not giving a
name except in the rare case where it is necessary.

Marc-André Lureau ab94c6b42f qdev: fix -device scsi-hd,help regression
Since commit ea9ce8934, device_post_init() applies globals directly
from machines and accelerator classes.

There are cases, such as -device scsi-hd,help, where the machine is
setup but there in no accelerator.

Let's skip accelerator globals in this case.

Fixes SEGV:

Eduardo Habkost e0985450e1 machine: Eliminate unnecessary stringify() usage
stringify() is useful when we need to use macros in compat_props
(like when we set virtio-baloon-pci.class=PCI_CLASS_MEMORY_RAM at
pc_i440fx_1_0_machine_options()), but it is pointless when we are
already providing a number literal.

Replace stringify() with string literals when appropriate.

Nick Hudson f831f955d4 Support u-boot noload images for arm as used by, NetBSD/evbarm GENERIC kernel.
noload kernels are loaded with the u-boot image header and as a result
the header size needs adding to the entry point.  Fake up a hdr so the
kernel image is loaded at the right address and the entry point is
adjusted appropriately.

The default location for the uboot file is 32MiB above bottom of DRAM.
This matches the recommendation in Documentation/arm/Booting.

Clarify the load_uimage API to state the passing of a load address when an
image doesn't specify one, or when loading a ramdisk is expected.

Adjust callers of load_uimage, etc.

Marc-André Lureau fa0cb34d22 hostmem: use object id for memory region name with >= 4.0
hostmem-file and hostmem-memfd use the whole object path for the
memory region name, and hostname-ram uses only the path component (the
object id, or canonical path basename):

qemu -m 1024 -object memory-backend-file,id=mem,size=1G,mem-path=/tmp/foo -numa node,memdev=mem -monitor stdio
(qemu) info ramblock
              Block Name    PSize              Offset               Used              Total
            /objects/mem    4 KiB  0x0000000000000000 0x0000000040000000 0x0000000040000000

              Block Name    PSize              Offset               Used              Total

qemu -m 1024 -object memory-backend-ram,id=mem,size=1G -numa node,memdev=mem -monitor stdio
(qemu) info ramblock
              Block Name    PSize              Offset               Used              Total

For consistency, change to use object id for -file and -memfd as well
with >= 4.0.

Having a consistent naming allows to migrate to different hostmem
backends.

Marc-André Lureau 55df8e1a2f qdev: all globals are now user-provided
All globals are now either provided via -global or through -cpu
features (CPU features are implemented by registering globals).

If the global isn't being used, it should warn in either case.

We can thus consider that all global_props are "user-provided"
globals. No need to track this per-globals anymore.

Peter Xu b2fc91db84 q35: set split kernel irqchip as default
Starting from QEMU 4.0, let's specify "split" as the default value for
kernel-irqchip.

So for QEMU>=4.0 we'll have: allowed=Y,required=N,split=Y
   for QEMU<=3.1 we'll have: allowed=Y,required=N,split=N
   (omitting all the "kernel_irqchip_" prefix)

Note that this will let the default q35 machine type to depend on
Linux version 4.4 or newer because that's where split irqchip is
introduced in kernel.  But it's fine since we're boosting supported
Linux version for QEMU 4.0 to around Linux 4.5.  For more information
please refer to the discussion on AMD's RDTSCP:

Thomas Huth 3858ff7639 hw/core: Move null-machine into the common-obj list
The null-machine code used to be target specific since it used the
target-specific cpu_init() function in the past. But in the recent
commit 2278b93941 ("Use cpu_create(type) instead of
cpu_init(cpu_model)") this has been change, so that the code now
uses the common cpu_create() function instead. Thus we can put
the null-machine into the common-obj list so that it is compiled
only once for all targets, to save some compilation time.

Igor Mammedov 8b5e6caf01 call HotplugHandler->plug() as the last step in device realization
When [2] was fixed it was agreed that adding and calling post_plug()
callback after device_reset() was low risk approach to hotfix issue
right before release. So it was merged instead of moving already
existing plug() callback after device_reset() is called which would
be more risky and require all plug() callbacks audit.

Looking at the current plug() callbacks, it doesn't seem that moving
plug() callback after device_reset() is breaking anything, so here
goes agreed upon [3] proper fix which essentially reverts [1][2]
and moves plug() callback after device_reset().
This way devices always comes to plug() stage, after it's been fully
initialized (including being reset), which fixes race condition [2]
without need for an extra post_plug() callback.

 2. (8449bcf94 "virtio-scsi: fix hotplug ->reset() vs event race")

Thomas Huth 1a1ff38c55 hw/core/generic-loader: Compile only once, not for each target
The generic-loader is currently compiled target specific due to one
single "#ifdef TARGET_WORDS_BIGENDIAN" in the file. We have already a
function called target_words_bigendian() for this instead, so we can
put the generic-loader into common-obj to save some compilation time.
