[edk2] [PATCH] MdeModulePkg/Core/Dxe: log informative memprotect msgs at DEBUG_INFO level
Posted by Laszlo Ersek 6 years, 4 months ago 
In commit 7eb927db3e25 ("MdeModulePkg/DxeCore: implement memory protection
policy", 2017-02-24), we added two informative messages with the
InitializeDxeNxMemoryProtectionPolicy() function:

> InitializeDxeNxMemoryProtectionPolicy: applying strict permissions to
> active memory regions

and

> InitializeDxeNxMemoryProtectionPolicy: applying strict permissions to
> inactive memory regions

The messages don't report errors or warnings, thus downgrade their log
masks from DEBUG_ERROR to DEBUG_INFO.
