Subject: [PATCHv4 12/18] x86/mm: Rename CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING
Date: Tue, 26 Jun 2018 17:22:39 +0300	[thread overview]
Message-ID: <20180626142245.82850-13-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20180626142245.82850-1-kirill.shutemov@linux.intel.com>

Rename the option to CONFIG_MEMORY_PHYSICAL_PADDING. It will be used
not only for KASLR.
