      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.

      HID: fix hid-ff drivers so that devices work even without ff support · 0f6f4319
      Jiri Kosina 提交于
      Currently, the hid-*ff force feedback drivers, which claim the blacklisted
      device on a HID bus, are only compiled in if the user selects force feedback
      support.
      
      However we want the device to be supported even when the kernel is configured
      without force feedback.
      
      This patch fixes the drivers in a way that they get compiled even if force
      feedback is turned off; all the force feedback support code is compiled out in
      such case, and the driver works as a usual driver on HID bus, claiming and
      initializing the device, making it operational without FF effects.

      HID: remove compat stuff · afa5eb7c
      Jiri Slaby 提交于
      This removal was scheduled and there is no problem with later
      distros to adapt for the new bus, thanks to aliases.
      
      module-init-tools map files are deprecated nowadays, so that
      the patch which introduced hid ones into the m-i-t won't be
      accepted and hence there is no reason for leaving compat stuff in.

      HID: fix a potential bug in pointer casting · 3ba5619f
      Li Zefan 提交于
      Don't directly cast list_head * to foo *, this works only when list
      is the first member of struct foo, and we should not make the assumption
      how members are ordered in the structure.
      
      i.e. struct *f = (struct *f)pos will work if:
      	struct foo {
      		struct list_head list;
      		int i;
      	};
      
      but will fail if:
      	struct foo {
      		int i;
      		struct list_head list;
      	}

      HID: make debugging output runtime-configurable · 58037eb9
      Jiri Kosina 提交于
      There have been many reports recently about broken HID devices, the
      diagnosis of which required users to recompile their kernels in order
      to be able to provide debugging output needed for coding a quirk for
      a particular device.
      
      This patch makes CONFIG_HID_DEBUG default y if !EMBEDDED and makes it
      possible to control debugging output produced by HID code by supplying
      'debug=1' module parameter.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
