Subject: [PATCH 04/29] alpha: Rename PT_LOAD identifier "kernel" to "text"
Date: Thu, 26 Sep 2019 10:55:37 -0700 [thread overview]
Message-ID: <20190926175602.33098-5-keescook@chromium.org> (raw)
In-Reply-To: <20190926175602.33098-1-keescook@chromium.org>
In preparation for moving NOTES into RO_DATA, this renames the linker
script internal identifier for the PT_LOAD Program Header from "kernel"
to "text" to match other architectures.
