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
