Subject: [PATCH] x86_64: fix 'earlyprintk=...,keep' regression
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24d7bb3396c51ceb2285e0e7b0c1bd1865652c43;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] x86_64: fix 'earlyprintk=...,keep' regression

Commit 2c8c0e6b8d7700a990da8d24eff767f9ca223b96 ("[PATCH] Convert x86-64
to early param") broke the earlyprintk=...,keep feature.

This restores that functionality.  Tested on x86_64.  Must-have for
v2.6.19, no risk.
