2011-05-22KVM: x86 emulator: Use opcode::execute for PUSHA/POPA (60/61)Takuya Yoshikawa
For this, emulate_pusha/popa() are converted to em_pusha/popa(). Signed-off-by: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-05-22KVM: x86 emulator: Use opcode::execute for POP reg (58-5F)Takuya Yoshikawa
In addition, the RET emulation is changed to call em_pop() to remove the pop_instruction label. Signed-off-by: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-05-22KVM: x86 emulator: Use opcode::execute for Group 1, CMPS and SCASTakuya Yoshikawa
The following instructions are changed to use opcode::execute. Group 1 (80-83) ADD (00-05), OR (08-0D), ADC (10-15), SBB (18-1D), AND (20-25), SUB (28-2D), XOR (30-35), CMP (38-3D) CMPS (A6-A7), SCAS (AE-AF) The last two do the same as CMP in the emulator, so em_cmp() is used.

2011-05-22KVM: MMU: Optimize guest page table walkTakuya Yoshikawa
This patch optimizes the guest page table walk by using get_user() instead of copy_from_user(). With this patch applied, paging64_walk_addr_generic() has become about 0.5us to 1.0us faster on my Phenom II machine with NPT on.

2011-05-22KVM: MMU: Make cmpxchg_gpte aware of nesting tooRoedel, Joerg
This patch makes the cmpxchg_gpte() function aware of the difference between l1-gfns and l2-gfns when nested virtualization is in use. This fixes a potential data-corruption problem in the l1-guest and makes the code work correct (at least as correct as the hardware which is emulated in this code) again.

2011-05-22KVM: x86 emulator: emulate CLTS internallyAvi Kivity
Avoid using ctxt->vcpu; we can do everything with ->get_cr() and ->set_cr(). A side effect is that we no longer activate the fpu on emulated CLTS; but that should be very rare. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-05-22x86, apic: Introduce .apicdrivers section to find the list of apic driversSuresh Siddha
This will pave the way for each apic driver to be self-contained and eliminate the need for apic_probe[]. Order in which apic drivers are listed in the .apicdrivers section is important, as this determines the apic probe order. And this is enforced by the ordering of apic driver files in the Makefile and the macros apic_driver()/apic_drivers().
