      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.

      Input: bcm5974 - retract efi-broken suspend_resume · d90e6f6a
      Henrik Rydberg 提交于
      With the recent system-wide improvements on suspend/resume and EFI
      booting the suspend_resume method of the bcm5974 has broken. When
      waking up from the S3 state on the MacBookAir, the trackpad is found
      in a yet unknown state, unable to switch to the proper multitouch
      mode. The result is a frozen touchpad, and a flood of errors of the
      kind
      
      	bcm5974: bad trackpad package, length: 8.
      
      This patch retracts the reset_resume method altogether, falling back
      on the generic unbind/rebind functionality of the usb layer until
      further investigations can be made as how to reset the device when
      booting from efi.

      Input: appletouch - fix integer overflow issue · 04b4b88c
      Vadim Zaliva 提交于
      When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
      PowerBooks the driver was casting X and Y coordinates values to
      'signed char'. Testing on one of such PowerBooks I have noticed that
      touchpad always generates positive values, but some of them are greater
      that 127, and thus, when cast to 'signed char' being interpreted as
      a negative.
      
      Such bigger values have been observed infrequently, closer to the
      edges of a touchpad, so the problem was not very visible.
      Nevertheless, the patch would potentially improve touchpad
      driver accuracy.

      Input: psmouse - fix Synaptics detection when protocol is disabled · e4e6efd2
      Daniel Drake 提交于
      For configurations where Synaptics hardware is present but the Synaptics
      extensions support is not compiled in, the mouse is reprobed and a new
      device is allocated on every suspend/resume.
      
      During probe, psmouse_switch_protocol() calls psmouse_extensions() with
      set_properties=1. This calls the dummy synaptics_init() which returns an
      error code, instructing us not to use the synaptics extensions.
      
      During resume, psmouse_reconnect() calls psmouse_extensions() with
      set_properties=0, in which case call to synaptics_init() is bypassed and
      PSMOUSE_SYNAPTICS is returned. Since the result is different from previous
      attempt psmouse_reconnect() fails and full re-probe happens.
      
      Fix this by tweaking the set_properties=0 codepath in psmouse_extensions()
      to be more careful about offering PSMOUSE_SYNAPTICS extensions.
