Hello Alexey, Looks like the following commit broke mmap for /proc/vmcore:
commit c4fe24485729fc2cbff324c111e67a1cc2f9adea Author: Alexey Dobriyan <[email protected]> Date: Tue Aug 20 22:17:24 2013 +0300 sparc: fix PCI device proc file mmap(2) Because /proc/vmcore (fs/proc/vmcore.c) does not implement the get_unmapped_area() fops function mmap now always returns EIO.
