Subject: [PATCH] KVM: x86 emulator: don't depend on cr2 for mov abs emulation

The 'mov abs' instruction family (opcodes 0xa0 - 0xa3) still depends on cr2
provided by the page fault handler.  This is wrong for several reasons:

- if an instruction accessed misaligned data that crosses a page boundary,
  and if the fault happened on the second page, cr2 will point at the
  second page, not the data itself.

- if we're emulating in real mode, or due to a FlexPriority exit, there
  is no cr2 generated.

So, this change adds decoding for this instruction form and drops reliance
on cr2.
