A typical demand page/copy on write pattern is:
- page fault on vaddr
- kvm propagates fault to guest
- guest handles fault, updates pte
- kvm traps write, clears shadow pte, resumes guest
- guest returns to userspace, re-faults on same vaddr
- kvm installs shadow pte, resumes guest
- guest
This improves kbuild times by about 10%, bringing it within a respectable
25% of native.

The lightweight vmexit path avoids saving and reloading certain host
state. However in certain cases lightweight vmexit handling can schedule()
which requires reloading the host state.
So we store the host state in the vcpu structure, and reloaded it if we

MSR_EFER.LME/LMA bits are automatically save/restored by VMX
hardware, KVM only needs to save NX/SCE bits at time of heavy
weight VM Exit. But clearing NX bits in host envirnment may
cause system hang if the host page table is using EXB bits,
thus we leave NX

'2.6.22-rc regression: s2ram fails to suspend + fails to resume w/ Xorg':
The first one was just the wrong coretemp patch (already fixed by Jean).
The second one happens only with Xorg/fglrx loaded and slub enabled, as
I've found after a useless git

Those regressions where we know which patch caused them are the easy ones.
Often we don't

I am ccing this to kernel mailing list, cause in my point of view this at
least partly points at a failure of proper kernel management.

Actually I don't keep a tree for header stuff (except for the automatic

Dear Kernel Developers,
I had some trouble with my usb devices, often showing a disconnect problem. I
did some googleing and saw, that it is a less or more common problem.
This problem is discussed in various internet sites.
log from my machine:

I don't know any law that requires tivoization.
In the USSA it is arguable that wireless might need it (if done in
software) for certain properties. (The argument being it must be
tamperproof to random end consumers). Obviously an electronics graduate
can tamper with hardware ones just as well
Sound recording doesn't work for this card because ACNI and ACPF
are not set before snd_card_saa7134_capture_prepare(). As a result
timeout occurs. These registers aren't poked because thread
never gets wake up signal. ACNI initialization is done in the
thread.
Sound is muted when capture stops.

Any idea when you'll be merging with Linus?
I just checked mainline git and the bug is still there :-(
This bug is in debugging code and is nearly impossible to hit,
so it will be merged during the next merge window.
