+Subject: arch: define weak abort()
+
+From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>
+
+commit 7c2c11b208be09c156573fc0076b7b3646e05219 upstream.
+
+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.

+Subject: crypto: tcrypt - fix S/G table for test_aead_speed()
+
+From: Robert Baronescu <robert.baronescu@nxp.com>
+
+commit 5c6ac1d4f8fbdbed65dbeb8cf149d736409d16a1 upstream.
+
+In case buffer length is a multiple of PAGE_SIZE,
+the S/G table is incorrectly generated.
+Fix this by handling buflen = k * PAGE_SIZE separately.

+gcc -fisolate-erroneous-paths-dereference can generate calls to abort()
