Hello.
I encountered a BUG().
I didn't encounter this bug for 2.6.24-rc5-mm1 .
I guess this bug was introduced between 2.6.24-rc5-mm1 and 2.6.24-rc6-mm1 .
I placed .config at http://I-love.SAKURA.ne.jp/tmp/config-2.6.24-rc6-mm1

Hello.
Thank you for attending discussion for previous posting
(starting from http://lkml.org/lkml/2007/12/16/23 ).
The previous posting was for feasibility test to know
whether this kind of trivial filesystem is acceptable for mainline.
Now, it seems that there is a little chance for accepting.
While looking for something else I stumbled over
wistron_btns-add-support-for-x86_64-systems.patch
in -mm. The patch looks very dubious to me. It basically
calls a BIOS function in long mode. To work like implemented
the BIOS would need to know magically what it was called
from (32bit or 64bit)
Following is the first part of the 2.6.25 merge window submission. Since
there are 238 patches in the queue (and a few more expected), they'll be
sent in five batches of around 50 each.

KVM avoids reloading the efer msr when the difference between the guest

ppc and s390 offer the possibility to track process times precisely
by looking at cpu timer on every context switch, irq, softirq etc.
We can use that infrastructure as well for guest time accounting.

The current kvm mmu only reverse maps writable translation. This is used
to write-protect a page in case it becomes a pagetable.
But with swapping support, we need a reverse mapping of read-only pages as
well: when we evict a page, we need to remove any mapp

In case the page is not present in the guest memory map, return a dummy
page the guest can scribble on.
This simplifies error checking in its users.

This allows guest memory to be swapped. Pages which are currently mapped
via shadow page tables are pinned into memory, but all other pages can
be freely swapped.
The patch makes gfn_to_page() elevate the page's reference count, and

Allocate a userspace buffer for older userspaces. Also eliminate phys_mem
buffer. The memset() in kvmctl really kills initial memory usage but swapping
works even with old userspaces.
A side effect is that maximum guest side is reduced for older userspa

Simplify the walker level loop not to carry so much information from one
loop to the next. In addition to being complex, this made kmap_atomic()
critical sections difficult to manage.
As a result of this change, kmap_atomic() sections are limited to actually
touching the guest pte, which allows t
We now have a new namespace, KVM_REQ_*, for bits in vcpu->requests.

Beside the obvious goodness of making code more common, this prevents
a livelock with the next patch which moves interrupt injection out of the
