🐛 Bug Fixes

• patina\_dxe\_core: Only Unmap Page 0 If It Exists @os-d (#610)
  
  Change Details

    ## Description

  This patch updates the logic to unmap page 0 after resource HOBs are added. It previously attempted to always do it, but on some platforms page 0 does not exist (in which case the page table will not map it anyway). This checks if the memory exists before attempting to unmap, so it does not cause a debug_assert.

  • Impacts security?
  • Breaking change?

  How This Was Tested

  Tested on a physical platform that did not have page 0 mapped and was hitting the debug_assert. It no longer is. Also tested on Q35 and SBSA booting to Windows.

  Integration Instructions

  N/A.
