      ALSA: Replace with IS_ENABLED() · 8eeaa2f9
      Takashi Iwai 提交于
      Replace the lengthy #if defined(XXX) || defined(XXX_MODULE) with the
      new IS_ENABLED() macro.
      
      The patch still doesn't cover all ifdefs.  For example, the dependency
      on CONFIG_GAMEPORT is still open-coded because this also has an extra
      dependency on MODULE.  Similarly, an open-coded ifdef in pcm_oss.c and
      some sequencer-related stuff are left untouched.

      ALSA: remove the main version information · 42662748
      Jaroslav Kysela 提交于
      Remove the main ALSA version number from the kernel ALSA driver.
      The ALSA driver package release diverges from the upstream. This may
      confuse users to see the same ALSA version for many kernel releases
      and this version lost it's original purpose and connection.
      
      The "ioctl" APIs have own version numbers, so the user space may check
      for specific API changes only.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      proc 2/2: remove struct proc_dir_entry::owner · 99b76233
      Alexey Dobriyan 提交于
      Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
      as correctly noted at bug #12454. Someone can lookup entry with NULL
      ->owner, thus not pinning enything, and release it later resulting
      in module refcount underflow.
      
      We can keep ->owner and supply it at registration time like ->proc_fops
      and ->data.
      
      But this leaves ->owner as easy-manipulative field (just one C assignment)
      and somebody will forget to unpin previous/pin current module when
      switching ->owner. ->proc_fops is declared as "const" which should give
      some thoughts.
      
      ->read_proc/->write_proc were just fixed to not require ->owner for
      protection.
      
      rmmod'ed directories will be empty and return "." and ".." -- no harm.
      And directories with tricky enough readdir and lookup shouldn't be modular.
      We definitely don't want such modular code.
      
      Removing ->owner will also make PDE smaller.
      
      So, let's nuke it.
      
      Kudos to Jeff Layton for reminding about this, let's say, oversight.

      PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures · 27ac792c
      Andrea Righi 提交于
      On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
      boundary. For example:
      
      	u64 val = PAGE_ALIGN(size);
      
      always returns a value < 4GB even if size is greater than 4GB.
      
      The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
      example):
      
      #define PAGE_SHIFT      12
      #define PAGE_SIZE       (_AC(1,UL) << PAGE_SHIFT)
      #define PAGE_MASK       (~(PAGE_SIZE-1))
      ...
      #define PAGE_ALIGN(addr)       (((addr)+PAGE_SIZE-1)&PAGE_MASK)
      
      The "~" is performed on a 32-bit value, so everything in "and" with
      PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
      Using the ALIGN() macro seems to be the right way, because it uses
      typeof(addr) for the mask.
      
      Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
      include/linux/mm.h.

      [ALSA] Remove sound/driver.h · 9004acc7
      Takashi Iwai 提交于
      This header file exists only for some hacks to adapt alsa-driver
      tree.  It's useless for building in the kernel.  Let's move a few
      lines in it to sound/core.h and remove it.
      With this patch, sound/driver.h isn't removed but has just a single
      compile warning to include it.  This should be really killed in
      future.
