Subject: 5.16-rc: "x86/boot: Pull up cmdline" breaks mem=
Date: Wed, 8 Dec 2021 21:44:54 -0800 (PST)	[thread overview]
Message-ID: <ae2bb14d-d27a-e76d-adde-ef888d373343@google.com> (raw)

Bad news, I'm afraid: I boot with "mem=1G" on the cmdline for testing,
which worked fine on 5.16-rc1, but does not work on 5.16-rc2 onwards.

Bisection arrived at 8d48bf8206f7 ("x86/boot: Pull up cmdline preparation
and early param parsing"); and reverting c0f2077baa41 ("x86/boot: Mark
prepare_command_line() __init") then 8d48bf820cf7 does fix my "mem=1G".

I have not tried 5.15-stable, but guess that is likewise afflicted.
Sympathy, but no suggestions from me: early init ordering is hard!

Hugh
