      [ARM] add Marvell 78xx0 ARM SoC support · 794d15b2
      Stanislav Samsonov authored
      The Marvell Discovery Duo (MV78xx0) is a family of ARM SoCs featuring
      (depending on the model) one or two Feroceon CPU cores with 512K of L2
      cache and VFP coprocessors running at (depending on the model) between
      800 MHz and 1.2 GHz, and features a DDR2 controller, two PCIe
      interfaces that can each run either in x4 or quad x1 mode, three USB
      2.0 interfaces, two 3Gb/s SATA II interfaces, a SPI interface, two
      TWSI interfaces, a crypto accelerator, IDMA/XOR engines, a SPI
      interface, four UARTs, and depending on the model, two or four gigabit
      ethernet interfaces.
      
      This patch adds basic support for the platform, and allows booting
      on the MV78x00 development board, with functional UARTs, SATA, PCIe,
      GigE and USB ports.

      |Basically, if a thread is running on a CPU, thread_saved_fp() is invalid.

      This does not seem to be a recent breakage.
      
      The ARCH_CO285 support is old - kernel 2.2.0 contains first traces of
      it, an it seems to have been pretty complete in later 2.2 kernels.
      
      Since it seems to be completely dead code now this patch therefore
      removes it.

      ARM: always select HAVE_IDE · 2064c946
      Adrian Bunk authored
      It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the
      availability of an asm/ide.h
      
      It turns out this was done for ARM, and we can simply always select 
      HAVE_IDE on ARM instead of manually tracking which platforms might 
      possible have an IDE controller directly or indirectly.

      As the procfs export of ATAGS is not meant as a stable, general purpose
      ABI it shouldn't be an independent, general configuration option.

      After seeing the filename I'd have expected something about the
      implementation of SMP in the Linux kernel - not some notes on kernel
      configuration and building trivialities noone would search at this
      place.

        - kprobes
      
      and
      
      init/Kconfig for architecture independent options
        - profiling
        - markers
      
      Remove the "Instrumentation Support" menu. Everything moves to "General setup".
      Delete the kernel/Kconfig.instrumentation file.

      Add HAVE_KPROBES · 3f550096
      Mathieu Desnoyers authored
      Linus:
      
      On the per-architecture side, I do think it would be better to *not* have
      internal architecture knowledge in a generic file, and as such a line like
      
              depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
      
      really shouldn't exist in a file like kernel/Kconfig.instrumentation.
      
      It would be much better to do
      
              depends on ARCH_SUPPORTS_KPROBES
      
      in that generic file, and then architectures that do support it would just
      have a
      
              bool ARCH_SUPPORTS_KPROBES
                      default y
      
      in *their* architecture files. That would seem to be much more logical,
      and is readable both for arch maintainers *and* for people who have no
      clue - and don't care - about which architecture is supposed to support
      which interface...
      
      Changelog:
      
      Actually, I know I gave this as the magic incantation, but now that I see
      it, I realize that I should have told you to just use
      
              config KPROBES_SUPPORT
                      def_bool y
      
      instead, which is a bit denser.
      
      We seem to use both kinds of syntax for these things, but this is really
      what "def_bool" is there for...
      
      - Use HAVE_KPROBES
      - Use a select
      
      - Yet another update :
      Moving to HAVE_* now.
      
      - Update ARM for kprobes support.
