Subject: [S390] Fix vmalloc area size calculation.
Date: Sun, 7 Jan 2007 11:44:03 +0100 [thread overview]
Message-ID: <20070107104403.GD14724@skybase> (raw)
From: Heiko Carstens <heiko.carstens@de.ibm.com>
[S390] Fix vmalloc area size calculation.
setup_memory_end() uses VMALLOC_END instead of VMALLOC_END_INIT to
calculate the maximum supported size of physical memory. Since
VMALLOC_END is zero, this will cause a crash on 31 bit systems.
