From 23dcab8f8e89bb25d7e156ffec4b27542d1f737a Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 22 Jul 2010 13:30:44 -0500 Subject: powerpc/kexec: Fix boundary case for book-e kexec memory limits The KEXEC_*_MEMORY_LIMITs are inclusive addresses. We define them as 2Gs as that is what we allow mapping via TLBs. However, this should be 2G - 1 to be inclusive, otherwise if we have >2G of memory in a system we fail to boot properly via kexec.
