       "There were lots of changes in this development cycle:
         - over 100 separate cleanups, restructuring changes, speedups and
           fixes in the x86 system call, irq, trap and other entry code, part
           of a heroic effort to deobfuscate a decade old spaghetti asm code
           and its C code dependencies (Denys Vlasenko, Andy Lutomirski)
         - alternatives code fixes and enhancements (Borislav Petkov)
         - simplifications and cleanups to the compat code (Brian Gerst)
         - signal handling fixes and new x86 testcases (Andy Lutomirski)
         - various other fixes and cleanups
        By their nature many of these changes are risky - we tried to test
        them well on many different x86 systems (there are no known
        regressions), and they are split up finely to help bisection - but
        there's still a fair bit of residual risk left so caveat emptor"

      avr32: fix integer overflow in ELF_ET_DYN_BASE · 940db9e6
      Andrey Ryabinin authored
      Almost all arches define ELF_ET_DYN_BASE as 2/3 of TASK_SIZE.
      Though it seems that some architectures do this in a wrong way.
      The problem is that 2*TASK_SIZE may overflow 32-bits so
      the real ELF_ET_DYN_BASE becomes wrong.
      Fix this overflow by dividing TASK_SIZE prior to multiplying:
      	 (TASK_SIZE / 3 * 2)
