Chris von Recklinghausen 86109a691a arm64: Fix kcore macros after 52-bit virtual addressing fallout ... We export the entire kernel address space (i.e. the whole of the TTBR1 address range) via /proc/kcore. The kc_vaddr_to_offset() and kc_offset_to_vaddr() macros are intended to convert between a kernel virtual address and its offset relative to the start of the TTBR1 address space. Prior to commit: 14c127c957 ("arm64: mm: Flip kernel VA space") ... the offset was calculated relative to VA_START, which at the time was the start of the TTBR1 address space. At this time, PAGE_OFFSET pointed to the high half of the TTBR1 address space where arm64's linear map lived. That commit swapped the position of VA_START and PAGE_OFFSET, but failed to update kc_vaddr_to_offset() or kc_offset_to_vaddr(), so since then the two macros behave incorrectly. Note that VA_START was subsequently renamed to PAGE_END in commit: 77ad4ce693 ("arm64: memory: rename VA_START to PAGE_END") As the generic implementations of the two macros calculate the offset relative to PAGE_OFFSET (which is now the start of the TTBR1 address space), we can delete the arm64 implementation and use those.
