KVM: Move arch dependent files to new directory arch/x86/kvm/

This paves the way for multiple architecture support.  Note that while
ioapic.c could potentially be shared with ia64, it is also moved.

- * x86_emulate_ops:
- *
- * These operations represent the instruction emulator's interface to memory.
- * There are two categories of operation: those that act on ordinary memory
- * regions (*_std), and those that act on memory regions known to require
- * special treatment or emulation (*_emulated).
- *
- * The emulator assumes that an instruction accesses only one 'emulated memory'
- * location, that this location is the given linear faulting address (cr2), and
- * that this is one of the instruction's data operands. Instruction fetches and
- * stack operations are assumed never to access emulated memory. The emulator
- * automatically deduces which operand of a string-move operation is accessing
- * emulated memory, and assumes that the other operand accesses normal memory.
- *
- * NOTES:
- *  1. The emulator isn't very smart about emulated vs. standard memory.
- *     'Emulated memory' access addresses should be checked for sanity.
- *     'Normal memory' accesses may fault, and the caller must arrange to
- *     detect and handle reentrancy into the emulator via recursive faults.
- *     Accesses may be unaligned and may cross page boundaries.
- *  2. If the access fails (cannot emulate, or a standard access faults) then
- *     it is up to the memop to propagate the fault to the guest VM via
- *     some out-of-band mechanism, unknown to the emulator. The memop signals
- *     failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
- *     then immediately bail.
- *  3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
- *     cmpxchg8b_emulated need support 8-byte accesses.
- *  4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.
