      PCI: Global variable decls must match the defs in section attributes · 491424c0
      David Howells authored
      Global variable declarations must match the definitions in section attributes
      as the compiler is at liberty to vary the method it uses to access a variable,
      depending on the section it is in.
      
      When building the FRV arch, I now see:
      
        drivers/built-in.o: In function `pci_apply_final_quirks':
        drivers/pci/quirks.c:2606: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o
        drivers/pci/quirks.c:2623: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o
        drivers/pci/quirks.c:2630: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o
      
      because the declaration of pci_dfl_cache_line_size in linux/pci.h does not
      match the definition in drivers/pci/pci.c.

      strayed down the rw_lock path.  Update the Documentation
      based upon comments by Eric Dumazet and Paul E. McKenney in
      those threads.
      
      Further updates await somebody else with more expertise.
      
      Changes:
        - Merged with extensive content by Stephen Hemminger.
        - Fix one of the comments by Linus Torvalds.

      perf sched: Fix build failure on sparc · 2cd9046c
      David Miller authored
      Here, tvec->tv_usec is "unsigned int" not "unsigned long".
      
      Since the type is different on every platform, it's probably
      best to just use long printf formats and cast.

      perf bench: Add "all" pseudo subsystem and "all" pseudo suite · 2044279d
      Hitoshi Mitake authored
      This patch adds a new "all" pseudo subsystem and an "all" pseudo
      suite. These are for testing all subsystem and its all suite, or
      all suite of one subsystem.
      
      (This patch also contains a few trivial comment fixes for
      bench/* and output style fixes. I judged that there are no
      necessity to make them into individual patch.)

      Microblaze version 7.20.d is the first MB version which can be run

      Based on WB support was necessary to redesign whole cache design.
      Microblaze versions from 7.20.a don't need to disable IRQ and cache
      before working with them that's why there are special structures for it.

      microblaze: Fix level interrupt ACKing · 33d9ff59
      steve@digidescorp.com authored
      Level interrupts need to be ack'd in the unmask handler, as in powerpc.
      Among other issues, this bug causes the system clock to appear to run at
      double-speed.

      microblaze: Remove the buggy ALLOW_EDIT_AUTO config option · 3e78e4e5
      John Williams authored
      This was intended to allow manual override of CPU settings copied automatically
      to Kconfig.auto, however it's problematic for several reasons, but mostly:
      
        * If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for
          that defconfig to iverride the values in the kernel source tree.  This leads
          to very strange errors where the kernel is compiled with the wrong CPUFLAGS.
      
      Next patch in the series will back out the default in Kconfig.auto to baseline
      settings, so a kernel built with no default values will at least boot on any
      hardware, just not make use of additional CPU features.

      Load address and entry point is for microblaze first instruction
      which is CONFIG_KERNEL_BASE_ADDR variable.
      
      There is possible for simpleImage format parse _start symbol too.
      
      simpleImage.<dts> is still stripped elf file
