Reviewed-by: Jeff Fan <[email protected]> -----Original Message----- From: edk2-devel [mailto:[email protected]] On Behalf Of Marvin Häuser Sent: Friday, July 21, 2017 6:20 PM To: [email protected] Cc: Fan, Jeff Subject: [edk2] [PATCH] UefiCpuPkg/PiSmmCpuDxeSmm: Cast the return value of GetPageTableBase().
The value returned by GetPageTableBase() is of type UINT64, which is implicitely casted to UINTN by the return statement. To purge the 'possible loss of data' warning on 32-bit platforms, with this patch, the value is casted to UINTN before returning.
