      kgdb: 1000 loops for the single step test in kgdbts · 7cfcd985
      Jason Wessel authored
      The single step test is not terribly costly and it should be able to
      pass at 1000 loops successfully in under 1 second.  A non-kgdb timing
      regression was found using this test, but it did not occur frequently
      because by default the test was only executed a single time.
      
      This patch changes the default for the single step test to 1000
      iterations and allows for individual configuration of the single step
      test to further exercise the kgdb subsystem when needed.

      sysfs: build fix · e73b65f1
      Ingo Molnar authored
      x86.git testing found the following build failure on v2.6.26-rc1:
      
        In file included from include/linux/kobject.h:22,
                         from include/linux/module.h:17,
                         from include/linux/crypto.h:22,
                         from arch/x86/kernel/asm-offsets_32.c:8,
                         from arch/x86/kernel/asm-offsets.c:3:
        include/linux/sysfs.h:201: error: redefinition of 'sysfs_update_group'
        include/linux/sysfs.h:195: error: previous definition of 'sysfs_update_group' was here
        make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1
        make: *** [prepare0] Error 2
      
      with the following config:
      
          http://redhat.com/~mingo/misc/config-Sun_May__4_07_09_30_CEST_2008.bad
      
      the reason for the build failure is the duplicate definition of the
      sysfs_update_group() inline function in include/linux/sysfs.h.
      
      The duplication was a merge error: it was added via -mm by commit
      v2.6.25-7262-g2850699c, "sysfs: sysfs_update_group stub for
      CONFIG_SYSFS=n" a day before v2.6.26-rc1, but a day before that the same
      commit was already merged upstream via the sysfs tree, with commit
      v2.6.25-7211-g1cbfb7a5.

      Make forced module loading optional · 826e4506
      Linus Torvalds authored
      The kernel module loader used to be much too happy to allow loading of
      modules for the wrong kernel version by default.  For example, if you
      had MODVERSIONS enabled, but tried to load a module with no version
      info, it would happily load it and taint the kernel - whether it was
      likely to actually work or not!
      
      Generally, such forced module loading should be considered a really
      really bad idea, so make it conditional on a new config option
      (MODULE_FORCE_LOAD), and make it default to off.
      
      If somebody really wants to force module loads, that's their problem,
      but we should not encourage it.  Especially as it happened to me by
      mistake (ie regular unversioned Fedora modules getting loaded) causing
      lots of strange behavior.
