uml: more __init annotations

Browse Source 
2.6.23-rc1 turned up another batch of references from non-__init code to
__init code.  In most cases, these were missing __init annotations.  In one
case (os_drop_memory), the annotation was present but wrong.

init_maps is __init, but for some reason was being very careful about the
mechanism by which it allocated memory, checking whether it was OK to use
kmalloc (at this point in the boot, it definitely isn't) and using either
alloc_bootmem_low_pages or kmalloc/vmalloc.  So, the kmalloc/vmalloc code is
removed.
