The problem is that all users of ux500 systems pass a command line like
vmalloc=256M mem=128M at 0 mali.mali_mem=32M at 128M hwmem=168M at 160M mem=48M at 328M mem_issw=1M at 383M mem=640M at 384M
This is of course totally bogus and should not be done. If I understand
Lee correctly, one of the issues resulting from passing a command
line like this without enabling highmem is memory corruption.
