Subject: [PATCH v3 07/27] x86: pm-trace - Adapt assembly for PIE support
Date: Wed, 23 May 2018 12:54:01 -0700 [thread overview]
Message-ID: <20180523195421.180248-8-thgarnie@google.com> (raw)
In-Reply-To: <20180523195421.180248-1-thgarnie@google.com>
Change assembly to use the new _ASM_MOVABS macro instead of _ASM_MOV for
the assembly to be PIE compatible.
Position Independent Executable (PIE) support will allow to extended the
KASLR randomization range below the -2G memory limit.
