Subject: [PATCH] x86-64: free_bootmem_node needs __pa in allocate_aperture
Date: Tue, 7 Mar 2006 11:26:51 -0600	[thread overview]
Message-ID: <20060307172651.GA26662@us.ibm.com> (raw)

free_bootmem_node expects a physical address to be passed in, but
__alloc_bootmem_node returns a virtual one.  That address needs to be
translated to physical.

Thanks,
Jon
