Subject: [patch 37/43] ppc64: make dma_addr_t 64 bits
Date: Fri, 28 Oct 2005 17:46:52 -0700 [thread overview]
Message-ID: <200510290047.j9T0lMO5030114@shell0.pdx.osdl.net> (raw)
From: Stephen Rothwell <sfr@canb.auug.org.au>
There has been a need expressed for dma_addr_t to be 64 bits on PPC64.
This patch does that. I have built it for pSeries and iSeries and booted a
virtual only iSeries partition.
