The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.

Disabling MMAP support uses the slower read/write accesses but allows to
trace all MMIO accesses, which is not good for performance, but very
useful for reverse engineering PCI drivers. This option allows to
disable MMAP per device without a compile-time change.

Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).
In all this time, nobody reported the loss. I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.
Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.
Remove the commands along with the code backing them.

Even if the caller has both the old and the new AioContext's, there can
be a deadlock, due to the leading bdrv_drain_all.
Suppose there are four io threads (A, B, A0, B0) with A and B owning a
BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and
B wants to move bs_b to B0, at the same time:
iothread A iothread B
--------------------------------------------------------------------------
aio_context_acquire(A0) /* OK */ aio_context_acquire(B0) /* OK */
bdrv_set_aio_context(bs_a, A0) bdrv_set_aio_context(bs_b, B0)
-> bdrv_drain_all() -> bdrv_drain_all()
-> acquire A /* OK */ -> acquire A /* blocked */
-> acquire B /* blocked */ -> acquire B
... ...
Deadlock happens because A is waiting for B, and B is waiting for A.

img_convert() and img_amend() use qemu_opts_do_parse(), which reports
errors with qerror_report_err(). Its error messages aren't helpful
here, the caller reports one that actually makes sense. Reproducer:
$ qemu-img convert -o backing_format=raw in.img out.img
qemu-img: Invalid parameter 'backing_format'
qemu-img: Invalid options for file format 'raw'
To fix, propagate errors through qemu_opts_do_parse(). This lifts the
error reporting into callers. Drop it from img_convert() and
img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create().
Since I'm touching qemu_opts_do_parse() anyway, write a function
comment for it.

qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().
Most of its users assume the function can't fail. Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.
Just two users remain, in util/qemu-config.c. Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.
Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.
Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.
impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.
PS:
Later Windows editions seem to be fine with above
conditions.

Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.
