There are some users that would like the ability of a temporary
per-cpu deactivation of the debugger trap.
More specifically, we have seen that when kvm-unit-tests runs with
kgdb enabled, the kernel halts on the debugger during the KVM x86

Hello,
The following two patches address an integration issue between KVM and
KGDB. The issue described in the patches can be triggered with vanilla
kernels that enable KGDB and KVM together on x86 (more specifically,
we bump into this with Fedora's 3.11 kernel from FC19).
On a kernel enabled
We have seen that when kvm-unit-tests runs with kgdb enabled, the
kernel halts on the debugger during the KVM x86 instruction emulation
that performs a test of a division by zero, and also during fwait.
This patch adds calls that temporarily disable the debugger trap.

We should not be using jump labels before they were initialized. Push back
the callback to until after jump label initialization.

I'm new to KVM and as a learning exercise I'd like to start a VM and
run a few instructions by using ioctls on /dev/kvm. This might be a
terrible idea, please say so if it is.
I haven't been able to find much information on it, but by reading the
API document and stracing qemu I've put together a

Hi Paolo,
Currently I can trap every first write/read to a memory page from
guest VM (add codes in tdp_page_fault). If I want to trace every
memory access to a page, how can I achieve such goal in KVM?
Thanks,
Arthur
