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().
