Subject: [PATCH v6 kspp-next 17/22] x86/boot: allow FG-KASLR to be selected
Date: Tue, 31 Aug 2021 16:41:09 +0200 [thread overview]
Message-ID: <20210831144114.154-18-alexandr.lobakin@intel.com> (raw)
In-Reply-To: <20210831144114.154-1-alexandr.lobakin@intel.com>
Now that we have full support of FG-KASLR from both kernel core
and x86 code, allow FG-KASLR to be enabled for x86_64 if the
"regular" KASLR is also turned on.
