efi: libstub enhancements for cmdline parsing and kaslr
|
expand
|
This adds support for the 'quiet' kernel command line parameter, so that meaningless debug prints can be prevented from corrupting the boot splash (#3) Secondly, it enables randomization of the UEFI runtime services region when KASLR is in effect (#4) Patches #1 and #2 are preparatory cleanup patches. Patch #4 trivially depends on #2 which is why they are part of the same series.
