Subject: [Early RFC 5/6] arch/powerpc: Make KERN_VIRT_SIZE not dependend on PGTABLE_RANGE
Date: Fri, 1 Jun 2012 01:20:40 +0530 [thread overview]
Message-ID: <1338493841-9926-6-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1338493841-9926-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
As we keep increasing PGTABLE_RANGE we need not increase the virual
map area for kernel.
