The following patch avoids the overlap by lowering the base address according to the values of NR_CPUS and KM_TYPE_NR. Is this the way to handle this? Thanks, Anders Anders Berg (1): ARM: mm: Fix for highmem on machines with more than 14 cores arch/arm/include/asm/fixmap.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) -- 1.8.3.2
