[XEN,00/12] x86: address violations of MISRA C Rule 16.3

Message

This patch series addresses violations of Rule 16.3 on the x86 code.

If all the 12 patches will be committed, only 4 violations will be left:
these are under x86_emulate and involve some fallthrough cases.
I'll wait for instructions from x86 maintainers about the right "format" to make
the fallthrough intention explicit (i.e., a comment or the fallthrough keyword
that is not defined in x86-emulate.h at the moment).
