      Fix following warning:
      
      WARNING: arch/sparc/kernel/built-in.o(.cpuinit.text+0x9f4): Section mismatch in reference from the function leon_callin() to the function .init.text:leon_configure_cache_smp()
      The function __cpuinit leon_callin() references
      a function __init leon_configure_cache_smp().
      If leon_configure_cache_smp is only used by leon_callin then
      annotate leon_configure_cache_smp with a matching annotation.

      sparc32: Move cache and TLB flushes over to method ops. · 5d83d666
      David S. Miller 提交于
      This eliminated most of the remaining users of btfixup.
      
      There are some complications because of the special cases we
      have for sun4d, leon, and some flavors of viking.
      
      It was found that there are no cases where a flush_page_for_dma
      method was not hooked up to something, so the "noflush" iommu
      methods were removed.
      
      Add some documentation to the viking_sun4d_smp_ops to describe exactly
      the hardware bug which causes us to need special TLB flushing on
      sun4d.

      sparc32: generic clockevent support · 62f08283
      Tkhai Kirill 提交于
      The kernel uses l14 timers as clockevents. l10 timer is used
      as clocksource if platform master_l10_counter isn't constantly
      zero. The clocksource is continuous, so it's possible to use
      high resolution timers. l10 timer is also used as clockevent
      on UP configurations.
      
      This realization is for sun4m, sun4d, sun4c, microsparc-IIep
      and LEON platforms. The appropriate LEON changes was made by
      Konrad Eisele.
      
      In case of sun4m's oneshot mode, profile irq is zeroed in
      smp4m_percpu_timer_interrupt(). It is maybe
      needless (double, triple etc overflow does nothing).
      
      sun4d is able to have oneshot mode too, but I haven't
      any way to test it. So code of its percpu timer handler
      is made as much equal to the current code as possible.
      
      The patch is tested on sun4m box in SMP mode by me,
      and tested by Konrad on leon in up mode (leon smp
      is broken atm - due to other reasons).

      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.
