Subject: [PATCH] [POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32
Date: Wed, 26 Mar 2008 17:44:18 -0500 (CDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0803261743540.29631@blarg.am.freescale.net> (raw)
Now that we have a proper variable that is the address of the top
of low memory we can use it to limit the lmb allocations.
