The google memconsole driver is currently broken upstream, as it tries to read memory that is described as reserved in /proc/iomem, by dereferencing a pointer obtained through phys_to_virt(). This triggers a kernel fault as such regions are unmapped after early boot. The proper workaround is to use ioremap_cache() / iounmap() around such accesses. As some unrelated changes, I also converted some printks to use pr_info() and added some missing __init annotations. Tested: booted dbg build, verified I could read /sys/firmware/log Signed-off-by: Michel Lespinasse <walken@google.com> Acked-by: Mike Waychison <mikew@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
