powerpc/mm: Use generic_get_unmapped_area() and call it from arch_get_unmapped_area()

2022-05-05T12:11:57+00:00

Use the generic version of arch_get_unmapped_area() which is now available at all time instead of its copy radix__arch_get_unmapped_area() To allow that for PPC64, add arch_get_mmap_base() and arch_get_mmap_end() macros. Instead of setting mm->get_unmapped_area() to either arch_get_unmapped_area() or generic_get_unmapped_area(), always set it to arch_get_unmapped_area() and call generic_get_unmapped_area() from there when radix is enabled. Do the same with radix__arch_get_unmapped_area_topdown() Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/393be1fa386446443682fdb74544d733f68ef3bb.1649523076.git.christophe.leroy@csgroup.eu

powerpc: Avoid circular header inclusion in mmu-hash.h

2019-02-23T11:31:39+00:00

When activating CONFIG_THREAD_INFO_IN_TASK, linux/sched.h includes asm/current.h. This generates a circular dependency. To avoid that, asm/processor.h shall not be included in mmu-hash.h. In order to do that, this patch moves into a new header called asm/task_size_64/32.h all the TASK_SIZE related constants, which can then be included in mmu-hash.h directly.
