x86/uv: memory allocation at initialization
Impact: on SGI UV platforms, fix boot crash UV initialization is currently called too late to call alloc_bootmem_pages(). The current sequence is: start_kernel() mem_init() free_all_bootmem() <--- discard of bootmem rest_init() kernel_init() smp_prepare_cpus() native_smp_prepare_cpus() uv_system_init() <--- uses alloc_bootmem_pages() It should be calling kmalloc().
