-Subject: [PATCH] arch: define weak abort()
-
-gcc toggle -fisolate-erroneous-paths-dereference (default at -O2
-onwards) isolates faulty code paths such as null pointer access, divide
-by zero etc.  If gcc port doesnt implement __builtin_trap, an abort() is
-generated which causes kernel link error.
-
-In this case, gcc is generating abort due to 'divide by zero' in
-lib/mpi/mpih-div.c.
-
-Currently 'frv' and 'arc' are failing.  Previously other arch was also
-broken like m32r was fixed by commit d22e3d69ee1a ("m32r: fix build
-failure").
-
-Let's define this weak function which is common for all arch and fix the
-problem permanently.  We can even remove the arch specific 'abort' after
-this is done.
