This change reorganizes and cleanups our patches to reduce the patch number from 314 patches to 187. That's achieved by dropping patches that are later reverted and squashing fixes for earlier patches that introduced features. There are no code changes and the diff with upstream is the same before and after the cleanup. Having fewer patches makes easier to manage the patchset and also will ease to rebase them on top of the latest grub-2.04 release. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH] Make it possible to subtract conditions from debug=
|
|
|
|
This makes it so you can do set debug to "all,-scripting,-lexer" and get the
|
|
obvious outcome. Any negation present will take preference over that
|
|
conditional, so "all,-scripting,scripting" is the same thing as
|
|
"all,-scripting".
