Kernel commit f5509cc18daa ("mm: Hardened usercopy") introduced the
BUG() we are hitting here.
This BUG() was also hit while reading kcore, which was fixed with
kernel commit df04abfd181a ("fs/proc/kcore.c: Add bounce buffer
for ktext data"). Not convinced if similar fix is ideal here.
Working on the fix.
This issue is not just observed with ssh dump target but also with
other dump targets. Updated the bug summary accordingly..
