TODO (know issues in CPU model):
-------------------------------

[!] The following 3DNow! instructions still not implemented:
	PF2IW_PqQq
	PFNACC_PqQq
	PFPNACC_PqQq
	PFCMPGE_PqQq
	PFCMPGT_PqQq
	PFCMPEQ_PqQq
	PFMIN_PqQq
	PFMAX_PqQq
	PFRCP_PqQq
	PFRSQRT_PqQq
	PFSUB_PqQq
	PFSUBR_PqQq
	PFADD_PqQq
	PFACC_PqQq,
	PFMUL_PqQq
	PFRCPIT1_PqQq
	PFRSQIT1_PqQq
	PFRCPIT2_PqQq

[!] CPUID does not report 3DNow! instruction set

[!] Some of APIC functionality still not implemented, for example

    - LVT pins handling
    - Filter interrupts according processor priority (PPR)

[!] REP NOP is PAUSE (on P4/XEON)

    When running in SMP mode, this means that we are in a spin loop.
    This processor should yield to the other one, as we are anyhow waiting
    for a lock, and any other processor is responsible for this.

[!] 32-bit linear address wrap when executing in legacy mode might be
    not implemented correctly for system memory accesses (like descriptor
    tables and etc)

[!] AMD and Intel x86_64 implementations are different.
    Currently Bochs emulation is according to Intel version.
    Do we need to support both ?

[!] More flexible CPUID - vendor and etc

[!] VMX:

   - Dual-monitor treatment of SMIs and SMM not implemented yet
   - VMENTER to not-active state not supported yet

[!] SSE4A, SMX, SVM, AVX
