Introduce CTR mode support for the cipher APIs.
CTR mode uses a counter rather than a traditional IV.
The counter has additional properties, including a nonce
and initial counter block. We reuse the ctx->iv as
the counter for conveniences.
Both libgcrypt and nettle are support CTR mode, the
cipher-builtin doesn't support yet.

In commit 9b6a3ea7a6 store_reg() was changed to mask
both bits 0 and 1 of the new PC value when in ARM mode.
Unfortunately this broke the exception return code paths
when doing a return from ARM mode to Thumb mode: in some
of these we write a new CPSR including new Thumb mode
bit via gen_helper_cpsr_write_eret(), and then use store_reg()
to write the new PC. In this case if the new CPSR specified
Thumb mode then masking bit 1 of the PC is incorrect
(these code paths correspond to the v8 ARM ARM pseudocode
function AArch32.ExceptionReturn(), which always aligns the
new PC appropriately for the new instruction set state).
Instead of using store_reg() in exception-return code paths,
call a new store_pc_exc_ret() which stores the raw new PC
value to env->regs[15], and then mask it appropriately in
the subsequent helper_cpsr_write_eret() where the new
env->thumb state is available.
This fixes a bug introduced by 9b6a3ea7a6 which caused
crashes/hangs or otherwise bad behaviour for Linux when
userspace was using Thumb.

registers compatible with the AST2400 FMC controller and the legacy
'SMC' controller is fully gone.
We keep the FMC object to act as the BMC SPI controller and add a new

When explicitly enabling unmigratable flags using "-cpu host"
(e.g. "-cpu host,+invtsc"), the requested feature won't be
enabled because cpu->migratable is true by default.
This is inconsistent with all other CPU models, which don't have
the "migratable" option, making "+invtsc" work without the need
for extra options.
This happens because x86_cpu_filter_features() uses
cpu->migratable as an argument for
x86_cpu_get_supported_feature_word(). This is not useful
because:
2) on "-cpu host" it only makes QEMU disable features that were
explicitly enabled in the command-line;
1) on all the other CPU models, cpu->migratable is already false.
The fix is to just use 'false' as an argument to
x86_cpu_get_supported_feature_word() in
x86_cpu_filter_features().
Note that:
* This won't change anything for people using using
"-cpu host" or "-cpu host,migratable=<on|off>" (with no extra
features) because the x86_cpu_get_supported_feature_word() call
on the cpu->host_features check uses cpu->migratable as
argument.
* This won't change anything for any CPU model except "host"
because they all have cpu->migratable == false (and only "host"
has the "migratable" property that allows it to be changed).
* This will only change things for people using "-cpu host,+<feature>",
where <feature> is a non-migratable feature. The only existing
named non-migratable feature is "invtsc".
In other words, this change will only affect people using
"-cpu host,+invtsc" (that will now get what they asked for: the
invtsc flag will be enabled). All other use cases are unaffected.

Cluster x2APIC cannot work without KVM's x2apic API when the maximal
APIC ID is greater than 8 and only KVM's LAPIC can support x2APIC, so we
forbid other APICs and also the old KVM case with less than 9, to
simplify the code.
There is no point in enabling EIM in forbidden APICs, so we keep it
enabled only for the KVM APIC; unconditionally, because making the
option depend on KVM version would be a maintanance burden.
Old QEMUs would enable eim whenever intremap was on, which would trick
guests into thinking that they can enable cluster x2APIC even if any
interrupt destination would get clamped to 8 bits.
Depending on your configuration, QEMU could notice that the destination
LAPIC is not present and report it with a very non-obvious:
KVM: injection failed, MSI lost (Operation not permitted)
Or the guest could say something about unexpected interrupts, because
clamping leads to aliasing so interrupts were being delivered to
incorrect VCPUs.
KVM_X2APIC_API is the feature that allows us to enable EIM for KVM.
QEMU 2.7 allowed EIM whenever interrupt remapping was enabled. In order
to keep backward compatibility, we again allow guests to misbehave in
non-obvious ways, and make it the default for old machine types.
A user can enable the buggy mode it with "x-buggy-eim=on".

The MMIO based interface to APIC doesn't work well with MSIs that have
upper address bits set (remapped x2APIC MSIs). A specialized interface
is a quick and dirty way to avoid the shortcoming.

Every configuration has only up to one APIC class and we'll be extending
the class with a function that can be called without an instanced
object, so a direct access to the class is convenient.
This patch will break compilation if some code uses apic_get_class()
with CONFIG_USER_ONLY.

x86_cpu_filter_features() will be reused by code that shouldn't
print any warning. Move the warning code to a new
x86_cpu_report_filtered_features() function, and call it from
x86_cpu_realizefn().

Add a new optional field to query-cpu-definitions schema:
"unavailable-features". It will contain a list of QOM properties
that prevent the CPU model from running in the current host.

Instead of treating the FP and SSE bits as special cases, add
them to the x86_ext_save_areas array. This will simplify the code
that calculates the supported xsave components and the size of
the xsave area.

Instead of keeping the aliases inside the feature name arrays and
require parsing the strings, just register alias properties
manually. This simplifies the code for property registration and
lookup.
Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
Instead of translating the feature name entries when adding
property names, store the actual property names in the feature
name array.
For reference, here is the full list of functions that use
FeatureWordInfo::feat_names:
* x86_cpu_get_migratable_flags(): not affected, as it just
check for non-NULL values.
* report_unavailable_features(): informative only. It will
start printing feature names with hyphens.
* x86_cpu_list(): informative only. It will start printing
feature names with hyphens
* x86_cpu_register_feature_bit_props(): not affected, as it
was already calling feat2prop(). Now we can remove the
feat2prop() calls safely.
So, the only user-visible effect of this patch are the new names
being used in help and error messages for users.

Instead of using custom feature name lookup code for
plus_features/minus_features, save the property names used in
"[+-]feature" and use object_property_set_bool() to set them.
We don't need a feat2prop() call because we now have alias
properties for the old names containing underscores.
Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
Registering the actual names containing underscores as aliases
will allow management software to be aware that the old
compatibility names are suported, and will make feat2prop() calls
unnecessary when using feature names.
Also, this will help us avoid making the code support underscores
on feature names that never had them in the first place. e.g.
"+tsc_deadline" was never supported and doesn't need to be
translated to "+tsc-deadline".
In other word: this will require less magic translation of
strings, and simple 1:1 match between the config options and
actual QOM properties.
Note that the underscores are still present in the
FeatureWordInfo::feat_names arrays, because
add_flagname_to_bitmaps() needs them to be kept. The next patches
will remove add_flagname_to_bitmaps() and will allow us to
finally remove the aliases from feat_names.

VME is already disabled automatically when using TCG. So, instead
of pretending it is there when reporting CPU model data on
query-cpu-* QMP commands (making every CPU model to be reported
as not runnable), we can disable it by default on all CPU models
when using TCG.
Do that by adding a tcg_default_props array that will work like
kvm_default_props.
