Title:
  ARM64_SW_TTBR0_PAN Should Be Enabled For Oracle Kernels

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux-oracle package in Ubuntu:
  Fix Released
Status in linux-oracle source package in Focal:
  Fix Released
Status in linux-oracle source package in Impish:
  Invalid

Bug description:
  == SRU Justification ==
  The config option CONFIG_ARM64_SW_TTBR0_PAN was unintentionally disabled in the
  linux-oracle kernels by the following commit:
  c25f2bf469b3 ("UBUNTU: [config] oracle: Bring-up for arm64 support")

  CONFIG_ARM64_SW_TTBR0_PAN is enabled for all other kernels and should be enabled
  for the oracle kernels.

  v2: * Add enforcment line to annotations.
      * Removed patch for Impish, since config was re-enabled by someone else in 
        that relese.

  == Fix ==
    UBUNTU: [config] oracle:  Enable CONFIG_ARM64_SW_TTBR0_PAN

  == Regression Potential ==
  Low.  Option was previously enabled.
