Hello,

kernel test robot noticed "Kernel_panic-not_syncing:stack-protector:Kernel_stack_is_corrupted_in:cpuidle_enter_state" on:

commit: 2f3d08f074b02aa449de27238fda72496c789034 ("intel_idle: Add support for using intel_idle in a VM guest using just hlt")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

[test failed on linus/master 3f01e9fed8454dcd89727016c3e5b2fbb8f8e50c]
[test failed on linux-next/master fe57d0d86f03a8b2afe2869a95477d0ed1824c96]

in testcase: boot

compiler: clang-15
test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 16G

(please refer to attached dmesg/kmsg for entire log/backtrace)

this issue doesn't not always happen, and we noticed both this commit and its
parent could have various
  Kernel_panic-not_syncing:stack-protector:Kernel_stack_is_corrupted_in:xxx
in similar context

since "dmesg.Kernel_panic-not_syncing:stack-protector:Kernel_stack_is_corrupted_in:cpuidle_enter_state"
only happens on this commit and never on parent in our tests, and this commit
itself is about intel_idle, though we don't have enough idea if this is really
irrelevant, just report what we observed in tests FYI.
