Hi Anup,
thanks for the re-spin and sorry for the delay.

Even after the recent fix, the assertion on paging_tmpl.h is triggered.
Apparently, the assertion wants to check that the PAE is always set on
long-mode, but does it in incorrect way. Note that the assertion is not
enabled unless the code is debugged by defining MMU_DEBUG.

This patch-set includes miscellaneous bug fixes.
Patches 1-2 fix KVM bugs that affect the correct behavior of VMs.
Patches 3-5 have no apparent implications in normal use. Nonetheless, they fix
code which is bluntly wrong.
Patch 6 is version 2 of previously submitted patch. It was revised
Determining flat mode according to cid_mask is wrong, since currently KVM
supports zero clusters in x2apic mode. Use ldr_bits instead.
Since we recalculate the apic map whenever the DFR is changed, the bug appears
to have no effect, and perhaps the entire check can be removed.

In long-mode, when the address size is 4 bytes, the linear address is not
truncated as the emulator mistakenly does. Instead, the offset within the
segment (the ea field) should be truncated according to the address size.
As Intel SDM says: In 64-bit mode, the effective address components are
GP and SS exceptions deliver as error-code the segment selector if the
exception occurred when the segment is loaded. However, if the exception
occurs during the memory access itself, due to limit violations, the error-code
should be zero. Fix it.

NoBigReal emulation should consider the effective address is between 0 and
0x instead of checking the logical address. Currently there are no
instructions which are marked with NoBigReal flag, so this bug currently has no
impact.

KVM does not deliver x2APIC broadcast messages with physical mode. Intel SDM
(10.12.9 ICR Operation in x2APIC Mode) states: A destination ID value of

Hi Paolo and Gleb,
The attached file is a preliminary version of AMD vPMU support for KVM.
Currently I am working on a formal patch set; but realized that there
are some design choice to make (see below). I thought it is better to
send it out now, asking for your comments before sending out
