Subject: [PATCH v6 01/29] vmlinux.lds.h: Create COMMON_DISCARDS
Date: Fri, 21 Aug 2020 12:42:42 -0700 [thread overview]
Message-ID: <20200821194310.3089815-2-keescook@chromium.org> (raw)
In-Reply-To: <20200821194310.3089815-1-keescook@chromium.org>
Collect the common DISCARD sections for architectures that need more
specialized discard control than what the standard DISCARDS section
provides.
