We used to have some better documentation in the arm64 memory.txt until commit 08375198b010 ("arm64: Determine the vmalloc/vmemmap space at build time based on VA_BITS") which removed it in favour of what the kernel was printing. Subsequently, the kernel VA layout printing was also removed. It would be nice to bring back the memory.txt, even if it is for a single configuration as per defconfig. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
