sparc: Fix /proc/kcore (3c08158e) · Commits · 戴 / test

/proc/kcore investigates the "System RAM" elements in /proc/iomem to initialize it's memory tables. Therefore we have to register them before it tries to do so. kcore uses device_initcall() so let's use arch_initcall() for the registry. Also we need ARCH_PROC_KCORE_TEXT to get the virtual addresses of the kernel image correct. Reported-by:
