Description: BOOT_IMAGE (Linux command line "error" reported in logs since v5.14)

This is the lowest-level bug possible, just pollution in the boot log witnessed via dmesg since Arch kernel 5.14.

Upstream denies responsibility and kicks it back down to distributors:

https://bugzilla.kernel.org/show_bug.cgi?id=214239

Steps to reproduce:
1) boot Arch with linux 5.14 or later
2) witness the single line of noise produced by the kernel in the log (sample):

[ 0.047266] Unknown command line parameters: BOOT_IMAGE=/boot/vmlinuz-linux

So, BOOT_IMAGE is no longer used or swallowed silently by the kernel...

Should this actually fall downstream to GRUB?
This task depends upon

This was expected when the commit was introduced [1]. Grub adds the parameter BOOT_IMAGE [2] which the kernel now issues a notice message about.

Guess we can close this with "won't fix", no? Any objections?

Not adding anything new, just reporting the fact that for me as well since update to v5.14 the exact same message appears in my `journalctl -b` output. I am actually surprised that users do not report this "en-masse". Also what is the use of BOOT_IMAGE now ?

kernel: Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=0f2397cc-ee76-44b5-b7d...
kernel: Unknown command line parameters: BOOT_IMAGE=/vmlinuz-linux

Same with syslinux
"Unknown kernel command line parameters "BOOT_IMAGE=../vmlinuz-linux", will be passed to user space."

uname -a:
