[C/linux-azure][D/linux-azure][SRU][PATCH 0/1] enable PAGE_POISONING, PAGE_POISONING_NO_SANITY, PAGE_POISONING_ZERO

Po-Hsu Lin (Sam)
BugLink: https://bugs.launchpad.net/bugs/1812624

Enable these options to match config setting in the generic kernels and
the requirement from the security team.

Note that this should not have performance impact as this will need to
be enabled with "page_poison=1" kernel boot option.

  UBUNTU: [Config]: enable PAGE_POISONING, PAGE_POISONING_NO_SANITY,
    PAGE_POISONING_ZERO

It makes sense to me to carry these config options from the main kernel.

From the Azure perspective since poisoning still requires a parameter
to be passed on the kernel boot line, we're okay with enabling these.
