Subject: decruft the early init / initrd / initramfs code v2
Date: Thu,  9 Jul 2020 17:17:57 +0200	[thread overview]
Message-ID: <20200709151814.110422-1-hch@lst.de> (raw)

Hi all,

this series starts to move the early init code away from requiring
KERNEL_DS to be implicitly set during early startup.  It does so by
first removing legacy unused cruft, and the switches away the code
from struct file based APIs to our more usual in-kernel APIs.

There is no really good tree for this, so if there are no objections
I'd like to set up a new one for linux-next.

Changes since v1:
 - add a patch to deprecated "classic" initrd support
