+From: Dave Anderson <anderson@redhat.com>

+Cc: onestero@redhat.com
+Subject: [PATCH v2] Restore live system crash analysis for ARM64
+
+This v2 version simplifies the copy out of the kimage_voffset value
+to user-space per Oleg's suggestion.
+
+Upstream status: N/A
+
+Test: v2 version tested successfully with a modified crash utility
+
+The following Linux 4.6 commit breaks support for live system
+crash analysis on ARM64:
+
+   commit a7f8de168ace487fa7b88cb154e413cf40e87fc6
+   Author: Ard Biesheuvel <ard.biesheuvel@linaro.org>
+   arm64: allow kernel Image to be loaded anywhere in physical memory
+
+The patchset drastically modified the kernel's virtual memory layout,
+where notably the static kernel text and data image was moved from the
+unity mapped region into the vmalloc region.  Prior to Linux 4.6,
+the kernel's __virt_to_phys() function was this:
+
+ #define __virt_to_phys(x)  (((phys_addr_t)(x) - PAGE_OFFSET + PHYS_OFFSET))
+
+When running on a live system, the crash utility could determine PAGE_OFFSET
+by looking at the virtual addresses compiled into the vmlinux file, and
+PHYS_OFFSET can be determined by looking at /proc/iomem.
+
+As of Linux 4.6, it is done differently:
+
+ #define __virt_to_phys(x) ({                                            \
+        phys_addr_t __x = (phys_addr_t)(x);                             \
+        __x & BIT(VA_BITS - 1) ? (__x & ~PAGE_OFFSET) + PHYS_OFFSET :   \
+                                 (__x - kimage_voffset); })
+
+The PAGE_OFFSET/PHYS_OFFSET section of the conditional expression is for
+traditional unity-mapped virtual addresses, but kernel text and static
+data requires the new "kimage_voffset" variable.  Unfortunately, the
+contents of the new "kimage_voffset" variable is not available or
+calculatable from a user-space perspective, even with root privileges.
+
+At least the ARM64 developers made its contents available to modules
+with an EXPORT_SYMBOL(kimage_voffset) declaration.  Accordingly, with
+a modification to the /dev/crash driver to return its contents, the
+crash utility can run on a live system.
+
+The patch allows for architecture-specific DEV_CRASH_ARCH_DATA ioctls
+to be created, where this is the first instance of one.
