      clk: convert ARM RealView to common clk · f9a6aa43
      Linus Walleij authored
      
      
      This converts the ARM RealView machine over to using the common
      clock. The approach is similar to the one used for the Integrator,
      and we're reusing the ICST wrapper code.
      
      We have to put the clock intialization in the timer init function
      for the clocks to be available when initializing the timer,
      keeping them in early_init() is too early for the common clk.
      
      Since we now have to go down and compile drivers/clk/versatile
      a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper
      code gets compiled into the kernel for either machine. A leftover
      CLK_VERSATILE in the Integrator Kconfig was fixed up to use
      the new symbol as well.
      
      Tested on ARM RealView PB1176.

      ARM: mach-realview and mach-versatile: retire custom LED code · e031cd51
      Bryan Wu authored
      
      
      This replaces the custom LED trigger code in mach-realview with
      some overarching platform code for the plat-versatile family that
      will lock down LEDs 2 thru 5 for CPU activity indication. The
      day we have 8 core ARM systems the plat-versatile code will have
      to become more elaborate.
      
      Tested on RealView PB11MPCore by invoking four different CPU
      hogs (yes > /dev/null&) and see the LEDs go on one at a time.
      They all go off as the hogs are killed. Tested on the PB1176
      as well - just one activity led (led 2) goes on and off with
      CPU activity.
      
      (bryan.wu@canonical.com: use ledtrig-cpu instead of ledtrig-arm-cpu)

      driver-core: remove sysdev.h usage. · edbaa603
      Kay Sievers authored
      
      
      The sysdev.h file should not be needed by any in-kernel code, so remove
      the .h file from these random files that seem to still want to include
      it.
      
      The sysdev code will be going away soon, so this include needs to be
      removed no matter what.

      ARM: 6204/1: Fixups for the RealView PB1176 · 48f1d5a3
      Linus Walleij authored
      
      
      This is a number of basic fixes to the PB1176 that makes it tick
      properly:
      
      - Detect MMC insertion/removal even when PL061 GPIO is not compiled
        in. The register to read this status directly is removed on the
        PB1176.
      - Define the UART3 on the DevChip (where is actually is) and define
        the new UART4 serial port on the FPGA.
      - Also define the clocks for these two UARTs apropriately.
      - Remove the false notion that the PB1176 should have its CLCD
        on the ISSP, this is not the case, it is in the DevChip.
      - Remove the defintions and the previously commented-out PL081
        DMAC. As confirmed by mail this was found to be broken on the
        PB1176 board and removed from the subsequent FPGA images.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      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.
