The GET_SUPPORTED_CPUID bug has been fixed and shouldn't be happening
from v3.2 onwards.
Do you still see the issue in older versions?

Hi, I think I've tracked down the bug that causes
"KVM_GET_SUPPORTED_CPUID failed: Argument list too long" errors when
using the kvm tool. Basically, this (possibly squished) code seems to
be to blame:

Hello All,
Non-development question, apologies if I am posting to the wrong list,
but I cannot seem to find linux kvm forum 2010 videos at the following
link:
http://www.linux-kvm.org/page/KVM_Forum_2010
Is there some place else where they might be present ?

The device never works in the guest after s2disk/resume cycle of the host. But
it always works if it's used by the host itself - even after a s2disk/resume
cycle.

Task switches can switch between Protected Mode and VM86. The current
mode must be updated during the task switch emulation so that the new
segment selectors are interpreted correctly and privilege checks
succeed.

Currently, all task switches check privileges against the DPL of the
TSS. This is only correct for jmp/call to a TSS. If a task gate is used,
the DPL of this take gate is used for the check instead. Exceptions,
external interrupts and iret shouldn't perform any check.

Though we have one rmap array for every level, those for large pages,
called rmap_pde, are coupled with write_count information and constitute
lpage_info arrays.
To hide this implementation details, we are now using __gfn_to_rmap()
which includes likely(level == PT_PAGE_TABLE_LEVEL) heuristics; t
We can also use this for PT_PAGE_TABLE_LEVEL to treat every level
uniformly.
