+Subject: [PATCH 1/9] avr32: add varargs handling of prctl syscall
+
+prctl is defined to use varargs in the header file, hence it needs varargs
+specific handling in the source. This patch properly handles the variodic
+argument before the syscall is passed to the kernel for the AVR32 architecture.

+Subject: [PATCH 8/9] malloc: fix race condition and other bugs in the no-mmu malloc
+
+Fixes multiple race conditions on mmb list. This was done by
+making the mmb_heap_lock into a recursive lock and making the
+regular heap_lock extend to cover the mmb heap handling.
+
+Also move the new_mmb allocation up to before the mmb list is
+iterated through to find the insertion point. When the mmb_heap
+also runs out and needs to be extended when the regular heap is
+just extended, the mmb list could be messed up.
