Hi Jaegeuk,
Let me try to understand this, in some cases, we can write a checkpoint pack
which has wrong cp_ver, like in 1st cp pack which has even version number or 2nd
cp pack which has odd version number, so if we load that kind of cp pack during

In the 4.9 kernel, virtually-mapped stacks will be supported and enabled by

on-stack buffers are being passed into the crypto API, which to support crypto
accelerators operates on 'struct page' rather than on virtual memory.

On Apollolake platforms, PCIe rootport takes a long time to resume
from S3. With 100ms delay before read pci conf, rootport takes
~200ms during resume.
commit 2f5d8e4ff947 ("PCI: pciehp: replace unconditional sleep with
config space access check") is the one that added the 100ms delay
before readi

tty_port_tty_get() might return a tty which is NULL
if the port is not associated with a tty
(e.g. due to close or hangup).
But lpuart_start_rx_dma() dereferences tty without any check.
