Hi, list!
I have a question about coding style in linux kernel. In
Documention/CodingStyle, it is said that "Linux style for comments is
the C89 "/* ... */" style. Don't use C99-style "// ..." comments."
_But_ I see a lot of '//' style comments in current kernel code.
Which is
PAGE_MASK is an unsigned long, so using it to mask physical addresses on
i386 (which are 64-bit wide) leads to truncation. This can result in
page->private of unrelated memory pages being modified, with disasterous
results.
Fix by not using PAGE_MASK for physical addresses; instead calculate
the
KVM shadow page tables are always in pae mode, regardless of the guest
setting. This means that a guest pde (mapping 4MB of memory) is mapped
to two shadow pdes (mapping 2MB each).
When the guest writes to a pte or pde, we intercept the write and emulate it.
We also remove any shadowed mappings
This patchset contains fixes I plan to submit pre 2.6.21: a fix for
large memory 32-bit hosts, and a fix for non-pae 32-bit guests.

This patchset updates the kvm userspace interface to what I hope will
be the long-term stable interface. Provisions are included for extending
the interface later. The patches address performance and cleanliness
concerns.
One patch is missing -- I'd like the string pio transfers not to include
This allows userspace to ignore the io.rep field. No a big deal, but
friendly.

KVM used to handle cpuid by letting userspace decide what values to
return to the guest. We now handle cpuid completely in the kernel. We
still let userspace decide which values the guest will see by having
userspace set up the value table beforehand (this is necessary to allow
management
Instead of passing a 'struct kvm_run' back and forth between the kernel and
userspace, allocate a page and allow the user to mmap() it. This reduces
needless copying and makes the interface expandable by providing lots of
free space.

Older userspace didn't care, but newer userspace (with the cpuid changes)
does.

That ioctl does not transfer any data, so it should be an _IO rather than an
_IOW.

This allows us to store offsets in the kernel/user kvm_run area, and be
sure that userspace has them mapped. As offsets can be outside the
kvm_run struct, userspace has no way of knowing how much to mmap.

Allow a special signal mask to be used while executing in guest mode. This
allows signals to be used to interrupt a vcpu without requiring signal
delivery to a userspace handler, which is quite expensive. Userspace still
receives -EINTR and can get the signal via sigwait().

We no longer emulate single instructions in userspace. Instead, we service
mmio or pio requests.

This is redundant, as we also return -EINTR from the ioctl, but it
allows us to examine the exit_reason field on resume without seeing
old data.
