commit 0ca15429f24f01791c6e9b3a0c419e01b36e3a3e Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Jun 28 21:26:41 2012 +0300
Intel cpus: use CPU_ADDR_BITS from Kconfig during CAR
Default CPU_ADDR_BITS is 36.
For Atom (model_106cx) use 32. This model is known to fail execution-in-place (XIP) with the default 36.
Pentium M should use 32, but doesn't even with this patch. Some Xeon and CORE(2) models should use 38 or 40.
