Linux: Automatically increase vm.max_map_count if it's too low (#4702)1.1.842
* memory: Check results of pinvoke calls
* Increase vm.max_map_count when running Ryujinx
* Add SupportedOSPlatform attribute for WindowsApiException
* Revert increasing vm.max_map_count via script
* Add LinuxHelper to detect and increase vm.max_map_count
With GUI dialogs, this should be a bit more user-friendly.
* Supply arguments as a list to RunPkExec
* Add error logging in case RunPkExec() fails
* Prevent Gtk from crashing
