95c077c919 kvm: x86: Prevent sign extension of DR7 in guest debugging mode
This unbreaks guest debugging when the 4th hardware breakpoint used for
guest debugging is a watchpoint of 4 or 8 byte lenght. The 31st bit of
DR7 is set in that case and used to cause a sign extension to the high
word which was breaking the guest state (vm entry failure).

31ce5e0c49 Add "broadcast" option for mce command
When the following test case is injected with mce command, maybe user could not
get the expected result.
    DATA
               command cpu bank status             mcg_status  addr   misc
        (qemu) mce     1   1    0xbd00000000000000 0x05        0x1234 0x8c

    Expected Result
           panic type: "Fatal Machine check"

That is because each mce command can only inject the given cpu and could not
inject mce interrupt to other cpus. So user will get the following result:
    panic type: "Fatal machine check on current CPU"

"broadcast" option is used for injecting dummy data into other cpus. Injecting
mce with this option the expected result could be gotten.

Usage:
    Broadcast[on]
           command broadcast cpu bank status             mcg_status  addr   misc
    (qemu) mce     -b        1   1    0xbd00000000000000 0x05        0x1234 0x8c

    Broadcast[off]
           command cpu bank status             mcg_status  addr   misc
    (qemu) mce     1   1    0xbd00000000000000 0x05        0x1234 0x8c

96912e3970 target-ppc: fix sNaN propagation
The current FPU code returns 0.0 if one of the operand is a
signaling NaN and the VXSNAN exception is disabled.

fload_invalid_op_excp() doesn't return a qNaN in case of a VXSNAN
exception as the operand should be propagated instead of a new
qNaN to be generated. Fix that by calling fload_invalid_op_excp()
only for the exception generation (if enabled), and use the softfloat
code to correctly compute the result.
