      s390/ap_bus: use and-mask instead of a cast · 7d6c3b49
      Heiko Carstens 提交于
      Let's get rid of another sparse false positive:
      
      drivers/s390/crypto/ap_bus.c:416:64: warning:
        cast truncates bits from constant value (102030405060708 becomes 5060708)
      
      So instead of using a cast let's use an and-mask.
      That way sparse remains silent and one doesn't always have to check
      if this is a valid warning/bug or just a false positive.

      s390/irq: remove split irq fields from /proc/stat · 420f42ec
      Heiko Carstens 提交于
      Now that irq sum accounting for /proc/stat's "intr" line works again we
      have the oddity that the sum field (first field) contains only the sum
      of the second (external irqs) and third field (I/O interrupts).
      The reason for that is that these two fields are already sums of all other
      fields. So if we would sum up everything we would count every interrupt
      twice.
      This is broken since the split interrupt accounting was merged two years
      ago: 052ff461 "[S390] irq: have detailed
      statistics for interrupt types".
      To fix this remove the split interrupt fields from /proc/stat's "intr"
      line again and only have them in /proc/interrupts.
      
      This restores the old behaviour, seems to be the only sane fix and mimics
      a behaviour from other architectures where /proc/interrupts also contains
      more than /proc/stat's "intr" line does.

      s390/comments: unify copyright messages and remove file names · a53c8fab
      Heiko Carstens 提交于
      Remove the file name from the comment at top of many files. In most
      cases the file name was wrong anyway, so it's rather pointless.
      
      Also unify the IBM copyright statement. We did have a lot of sightly
      different statements and wanted to change them one after another
      whenever a file gets touched. However that never happened. Instead
      people start to take the old/"wrong" statements to use as a template
      for new files.
      So unify all of them in one go.

      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.

      [S390] zcrypt: Do not add/remove devices in s/r callbacks · 5314af69
      Felix Beck 提交于
      Devices are no longer removed or added in the suspend and resume
      callbacks. Instead they are marked unregistered in suspend. In the
      resume callback the ap_scan_bus method is scheduled. The bus scan
      function will remove the old device and add new ones. This way all
      the device handling will be done in only one function. Additionaly
      the case where the domain might change during suspend/resume is
      caught. In that case the devices qid needs to re-calculated in
      order of having it found by the scan method.
