      init: fix in-place parameter modification regression · 08746a65
      Krzysztof Mazur authored
      Before commit 026cee00
      ("params: <level>_initcall-like kernel parameters") the __setup
      parameter parsing code could modify parameter in the
      static_command_line buffer and such modifications were kept. After
      that commit such modifications are destroyed during per-initcall level
      parameter parsing because the same static_command_line buffer is used
      and only parameters for appropriate initcall level are parsed.
      
      That change broke at least parsing "ubd" parameter in the ubd driver
      when the COW file is used.
      
      Now the separate buffer is used for per-initcall parameter parsing.

      modpost: Optionally ignore secondary errors seen if a single module build fails · eed380f3
      Guenter Roeck authored
      Commit ea4054a2 (modpost: handle huge numbers of modules) added
      support for building a large number of modules.
      
      Unfortunately, the commit changed the semantics of the makefile: Instead of
      passing only existing object files to modpost, make now passes all expected
      object files. If make was started with option -i, this results in a modpost
      error if a single file failed to build.
      
      Example with the current btrfs build falure on m68k:
      
      fs/btrfs/btrfs.o: No such file or directory
      make[1]: [__modpost] Error 1 (ignored)
      
      This error is followed by lots of errors such as:
      
      m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory
      m68k-linux-gcc: fatal error: no input files
      compilation terminated.
      make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored)
      
      This doesn't matter much for normal builds, but it is annoying for builds
      started with "make -i" due to the large number of secondary errors.
      Those errors unnececessarily clog any error log and make it difficult
      to find the real errors in the build.
      
      Fix the problem by adding a new parameter '-n' to modpost. If this parameter
      is specified, modpost reports but ignores missing object files.
      
      With this patch, error output from above problem is (with make -i):
      
      m68k-linux-ld: cannot find fs/btrfs/ioctl.o: No such file or directory
      make[2]: [fs/btrfs/btrfs.o] Error 1 (ignored)
      ...
      fs/btrfs/btrfs.o: No such file or directory (ignored)

      module: remove rmmod --wait option. · 3f2b9c9c
      Rusty Russell authored
      The option to wait for a module reference count to reach zero was in
      the initial module implementation, but it was never supported in
      modprobe (you had to use rmmod --wait).  After discussion with Lucas,
      It has been deprecated (with a 10 second sleep) in kmod for the last
      year.
      
      This finally removes it: the flag will evoke a printk warning and a
      normal (non-blocking) remove attempt.

      cfq: explicitly use 64bit divide operation for 64bit arguments · f3cff25f
      Anatol Pomozov authored
      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.
