Subject: [PATCH 0/2] Use generic code for virtual address of randomization of x86

From: Xiongwei Song <sxwjean@...il.com>

Hello,

The two patches are to use generic code for randomization of virtual
address of x86. Since the basic code logic of x86 is same as generic
code, so no need to implement these functions on x86, please see the
details in comments of patch 2.

Please review it.
