Subject: [PATCH 5/6] ARM: kvm: Use phys_addr_t instead of unsigned long in mm code
Date: Thu, 14 Nov 2013 14:37:45 -0500	[thread overview]
Message-ID: <1384457866-16135-6-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1384457866-16135-1-git-send-email-santosh.shilimkar@ti.com>

The unsigned long datatype is not sufficient for mapping physical addresses
greater than 4GB.

So fix the KVM mm code accordingly. Special thanks to Christopher for debug
help to figure out the bug.
