Most of this series is the same as Yang Zhong's, except for:
1) less stubs usage
2) splitting patch 2 ("vl: add tcg_enabled() for tcg related code") [Thomas]
3) reworked configure [Thomas, Daniel]

This will be useful when the functions are called, early in the configure
process, to filter out targets that do not support hardware acceleration.

I've sent an updated version of this patch in my series "target/m68k:
implement 680x0 FPU (part 3)".
Tha
Add fsinh, flognp1, ftanh, fatan, fasin, fatanh,
fsin, ftan, fetox, ftwotox, ftentox, flogn, flog10, facos,
fcos, fsincos.
As softfloat library does not provide these functions,
we use the libm of the host.

Since f3218a8 ("softfloat: add floatx80 constants")
floatx80_infinity is defined but never used.
This patch updates floatx80 functions to use
this definition.
This allows to define a different default Infinity
value on m68k: the m68k FPU defines infinity with
all bits set to zero in the mantissa.
We start by defining the floatx80 value of infinity on m68k, as
it differs from the standard one (0x instead of
0x8000). This patch superseds the patch I have
already sent that defines a "floatx80_default_inf" whereas
we have already a "floatx80_infinity": we should use

Use libm functions fmodl() and remainderl().
The quotient byte of the FPSR is updated with
the result of the operation.

Otherwise, QEMU on a host with MPX support will try to set guest
MSR_IA32_BNDCFGS although guest MPX is not enabled, and result in
abort.
For example,
qemu-system-x86_64 -enable-kvm -cpu qemu64,-mpx ...
aborts with messages:
qemu-system-x86_64: error: failed to set MSR 0xd90 to 0x0

I was trying to write a timer device and discovered that the ptimer
API wasn't actually documented, so I wrote some basic notes for it...
include/hw/ptimer.h | 120 ++
Both callers already had bytes available, but were scaling to
sectors. Move the scaling to internal code. In the case of
bdrv_aligned_pwritev(), we are now passing the exact offset
rather than a rounded sector-aligned value, but that's okay
as long as dirty bitmap widens start/bytes to granularit
Now that all callers are using byte-based interfaces, there's no
reason for our internal hbitmap to remain with sector-based
granularity. It also simplifies our internal scaling, since we
already know that hbitmap widens requests out to granularity
boundaries.
