I'll drop this patch for the time being - we don't have stuff in the
right order yet for lmb_alloc() to work immediately after arm_lmb_init()
with highmem present - lmb_alloc tries to allocate from unmapped or high
memory, which we then use __va() on and referencing the resulting pointer
causes an abort.
However, using lmb_alloc() for the OMAP framebuffers shouldn't be an
issue because the problem only happens if you want to immediately
dereference the memory.
