Christophe Leroy 4a45b7460c powerpc/mm: refactor ioremap vm area setup. ... PPC32 and PPC64 are doing the same once SLAB is available. Create a do_ioremap() function that calls get_vm_area and do the mapping. For PPC64, we add the 4K PFN hack sanity check to __ioremap_caller() in order to avoid using __ioremap_at(). Other checks in __ioremap_at() are irrelevant for __ioremap_caller(). On PPC64, VM area is allocated in the range [ioremap_bot ; IOREMAP_END] On PPC32, VM area is allocated in the range [VMALLOC_START ; VMALLOC_END] Lets define IOREMAP_START is ioremap_bot for PPC64, and alias IOREMAP_START/END to VMALLOC_START/END on PPC32 Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/42e7e36ad32e0fdf76692426cc642799c9f689b8.1566309263.git.christophe.leroy@c-s.fr		2019-08-27 13:03:35 +10:00
