[edk2-devel] [Patch V2 09/14] UefiCpuPkg/CpuPageTableLib: Add OUTPUT IsModified parameter.

Wed Mar 8 10:07:53 UTC 2023
Add OUTPUT IsModified parameter in PageTableMap() to indicate
if page table has been modified. With this parameter, caller
can know if need to call FlushTlb when the page table is in CR3.
