xtensa: fix stack dump output

xtensa: make __pa work with uncached KSEG addresses

2017-03-30T20:29:20+00:00

When __pa is applied to virtual address in uncached KSEG region the result is incorrect. Fix it by checking if the original address is in the uncached KSEG and adjusting the result. It looks better than masking off bits because pfn_valid would correctly work with new __pa results and it may be made working in noMMU case, once we get definition for uncached memory view. This is required for the dma_common_mmap and DMA debug code to work correctly: they both indirectly use __pa with coherent DMA addresses. In case of DMA debug the visible effect is false reports that an address mapped for DMA is accessed by CPU.

arch, mm: convert all architectures to use 5level-fixup.h

2017-03-09T19:48:47+00:00

If an architecture uses 4level-fixup.h we don't need to do anything as it includes 5level-fixup.h. If an architecture uses pgtable-nop*d.h, define __ARCH_USE_5LEVEL_HACK before inclusion of the header. It makes asm-generic code to use 5level-fixup.h. If an architecture has 4-level paging or folds levels on its own, include 5level-fixup.h directly. Signed-off-by: Kirill A. Shutemov Acked-by: Michal Hocko Signed-off-by: Linus Torvalds

Pull Xtensa updates from Max Filippov: - clean up bootable image build targets: provide separate 'Image', 'zImage' and 'uImage' make targets that only build corresponding image type. Make 'all' build all images appropriate for a platform - allow merging vectors code into .text section as a preparation step for XIP support - fix handling external FDT when the kernel is built without BLK_DEV_INITRD support * tag 'xtensa-20170303' of git://github.com/jcmvbkbc/linux-xtensa: xtensa: allow merging vectors into .text section xtensa: clean up bootable image build targets xtensa: move parse_tag_fdt out of #ifdef CONFIG_BLK_DEV_INITRD

Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.
