      mtd: do not use plain 0 as NULL · 42d7fbe2

      The first 3 arguments of 'mtd_device_parse_register()' are pointers,
      but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks

      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.

      [ARM] fix build-breaking 7a192ec3 commit · 67a52bb9
      Russell King 提交于
      The commit:
      
          platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
      
      contains this:
      
      -static int __exit pxa2xx_flash_remove(struct device *dev)
      +static int __exit pxa2xx_flash_remove(struct platform_device *dev)
      ...
      -       .remove         = __exit_p(pxa2xx_flash_remove),
      +       .remove         = __devexit_p(pxa2xx_flash_remove),
      
      which leads to the following build error:
      
      `pxa2xx_flash_remove' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o
      
      This is not the only instance of it in this patch - all __exit_p's
      touched by this patch have been converted to __devexit_p's without
      regard to the original function.
      
      Let's revert this change and, if we are going to convert functions
      to be __devexit/__devinit, lets have that as a _separate_ patch doing
      just that change.

      Reinstate lost flush_ioremap_region() fix to pxa2xx-flash driver · 355aaffd
      Linus Torvalds 提交于
      Commit 90833fda ("[ARM] 4554/1: replace
      consistent_sync() with flush_ioremap_region()") introduced a new
      "flush_ioremap_region()" function to be used by the MTD mainstone-flash
      and lubbock-flash drivers to fix a regression from around 2.6.18.
      
      Those drivers were independently merged into a single driver by Todd
      Poynor in commit e644f7d6 ("[MTD] MAPS:
      Merge Lubbock and Mainstone drivers into common PXA2xx driver")
      
      Later, those two commits were merged into the main MTD tree by commit
      b160292c ("Merge Linux 2.6.23") by David
      Woodhouse, but in that merge, the fix to use flush_iomap_region() got
      lost (as it was to files that now no longer existed).
      
      This reinstates the fix in the new driver.
