powerpc/prom_init: Move __prombss to it's own section and store it in .bss 2018-10-18T13:56:17+00:00 Benjamin Herrenschmidt benh@kernel.crashing.org 2018-10-15T02:49:58+00:00 5f69e38885c3483a1838dd946aaf0166b727ecbd This makes __prombss its own section, and for now store it in .bss. This will give us the ability later to store it elsewhere and/or free it after boot (it's about 8KB).
