hw/arm/nrf51: Rename ARMv7MState 'cpu' -> 'armv7m'
The ARMv7MState object is not simply a CPU, it also
contains the NVIC, SysTick timer, and various MemoryRegions.
Rename the field as 'armv7m', like other Cortex-M boards.

hw/arm/stellaris: Add 'armv7m' local variable
While the TYPE_ARMV7M object forward its NVIC interrupt lines,
it is somehow misleading to name it 'nvic'. Add the 'armv7m'
local variable for clarity, but also keep the 'nvic' variable
behaving like before when used for wiring IRQ lines.

target/arm: arm_reset_sve_state() should set FPSR, not FPCR
The pseudocode ResetSVEState() does:
FPSR = ZeroExtend(0x0800009f<31:0>, 64);
but QEMU's arm_reset_sve_state() called vfp_set_fpcr() by accident.
Before the advent of FEAT_AFP, this was only setting a collection of
RES0 bits, which vfp_set_fpsr() would then ignore, so the only effect
was that we didn't actually set the FPSR the way we are supposed to
do. Once FEAT_AFP is implemented, setting the bottom bits of FPSR
will change the floating point behaviour.
Call vfp_set_fpsr(), as we ought to.
(Note for stable backports: commit 7f2a01e7368f9 moved this function
from sme_helper.c to helper.c, but it had the same bug before the
move too.)

target/arm: Use uint32_t in vfp_exceptbits_from_host()
In vfp_exceptbits_from_host(), we accumulate the FPSR flags in
an "int", and our return type is also "int". However, the only
callsite returns the same information as a uint32_t, and
more generally we handle FPSR values in the code as uint32_t,
not int. Bring this function in to line with that convention.
There is no behaviour change because none of the FPSR bits
we set in this function are bit 31. The input argument to
the function remains 'int' because that is the return type
of the softfloat get_float_exception_flags().

target/arm: Define new fp_status_a32 and fp_status_a64
We want to split the existing fp_status in the Arm CPUState into
separate float_status fields for AArch32 and AArch64. (This is
because new control bits defined by FEAT_AFP only have an effect for
AArch64, not AArch32.) To make this split we will:
* define new fp_status_a32 and fp_status_a64 which have
identical behaviour to the existing fp_status
* move existing uses of fp_status to fp_status_a32 or
fp_status_a64 as appropriate
* delete the old fp_status when it has no uses left
In this patch we add the new float_status fields.
We will also need to split fp_status_f16, but we will do that
as a separate series of patches.

target/arm: Use fp_status_a32 in vfp_cmp helpers
The helpers vfp_cmps, vfp_cmpes, vfp_cmpd, vfp_cmped are used only from
the A32 decoder; the A64 decoder uses separate vfp_cmps_a64 etc helpers
(because for A64 we update the main NZCV flags and for A32 we update
the FPSCR NZCV flags). So we can make these helpers use the fp_status_a32
field instead of fp_status.

fpu: Rename float_flag_input_denormal to float_flag_input_denormal_flushed
Our float_flag_input_denormal exception flag is set when the fpu code
flushes an input denormal to zero. This is what many guest
architectures (eg classic Arm behaviour) require, but it is not the
only donarmal-related reason we might want to set an exception flag.
The x86 behaviour (which we do not currently model correctly) wants
to see an exception flag when a denormal input is *not* flushed to
zero and is actually used in an arithmetic operation. Arm's FEAT_AFP
also wants these semantics.
Rename float_flag_input_denormal to float_flag_input_denormal_flushed
to make it clearer when it is set and to allow us to add a new
float_flag_input_denormal_used next to it for the x86/FEAT_AFP
semantics.
Commit created with

and manual editing of softfloat-types.h and softfloat.c to clean
up the indentation afterwards and to fix a comment which wasn't
using the full name of the flag.

target/arm: Remove redundant advsimd float16 helpers
The advsimd_addh etc helpers defined in helper-a64.c are identical to
the vfp_addh etc helpers defined in helper-vfp.c: both take two
float16 inputs (in a uint32_t type) plus a float_status* and are
simple wrappers around the softfloat float16_* functions.
(The duplication seems to be a historical accident: we added the
advsimd helpers in 2018 as part of the A64 implementation, and at
that time there was no f16 emulation in A32. Then later we added the
A32 f16 handling by extending the existing VFP helper macros to
generate f16 versions as well as f32 and f64, and didn't realise we
could clean things up.)
Remove the now-unnecessary advsimd helpers and make the places that
generated calls to them use the vfp helpers instead. Many of the
helper functions were already unused.
(The remaining advsimd_ helpers are those which don't have vfp
versions.)

target/arm: Use FPST_A64_F16 for halfprec-to-other conversions
We should be using the F16-specific float_status for conversions from
half-precision, because halfprec inputs never set Input Denormal.
Without FEAT_AHP, using the wrong fpst here had no effect, because
the only difference between the A64_F16 and A64 fpst is its handling
of flush-to-zero on input and output, and the helper functions
vfp_fcvt_f16_to_* and vfp_fcvt_*_to_f16 all explicitly squash the
relevant flushing flags, and flush_inputs_to_zero was the only way
that IDC could be set.
With FEAT_AHP, the FPCR.AH=1 behaviour sets IDC for
input_denormal_used, which we will only ignore in
vfp_get_fpsr_from_host() for the A64_F16 fpst; so it matters that we
use that one for f16 inputs (and the normal one for single/double to
f16 conversions).

hw/usb/canokey: Fix buffer overflow for OUT packet
When USBPacket in OUT direction has larger payload
than the ep_out_buffer (of size 512), a buffer overflow
would occur.
It could be fixed by limiting the size of usb_packet_copy
to be at most buffer size. Further optimization gets rid
of the ep_out_buffer and directly uses ep_out as the target
buffer.
This is reported by a security researcher who artificially
constructed an OUT packet of size 2047. The report has gone
through the QEMU security process, and as this device is for
testing purpose and no deployment of it in virtualization
environment is observed, it is triaged not to be a security bug.
