Subject: [PATCH v8 09/14] x86/boot: allow FG-KASLR to be selected
Date: Thu,  2 Dec 2021 23:32:09 +0100	[thread overview]
Message-ID: <20211202223214.72888-10-alexandr.lobakin@intel.com> (raw)
In-Reply-To: <20211202223214.72888-1-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.
