      m68k: runtime patching infrastructure · fbe9c961
      Roman Zippel 提交于
      Add the basic infrastructure to allow runtime patching of kernel and modules
      to optimize a few functions with parameters, which are only calculated once
      during bootup and are otherwise constant.  Use this for the conversion between
      virtual and physical addresses.

      smpboot: fix cachesize comparison in smp_tune_scheduling() · 8387c1a4
      Linus Torvalds 提交于
      Jarek Poplawski noted that boot_cpu_data.x86_cache_size is signed int
      and can be < 0 too.
      
      In fact we test for it. Except we assigned it to an unsigned value..

      We subtract 12 off 'fp' before testing to see if it's below the low

      positive number, causing this test to succeed where it should fail.
