      [MIPS] Run checksyscalls for N32 and O32 ABI · fcbee641
      Atsushi Nemoto authored
      On 64-bit MIPS, only N64 ABI is checked by default.  This patch adds
      some rules for other ABIs.  This results in these warnings at the
      moment:

      [MIPS] Remove Momenco Jaguar ATX support · bef964e5
      Franck Bui-Huu authored
      It has some hackish code and it odd DMA results in the need to support
      old features in kernel code.

      [MIPS] Add basic SMARTMIPS ASE support · 9693a853
      Franck Bui-Huu authored
      This patch adds trivial support for SMARTMIPS extension. This extension
      is currently implemented by 4KS[CD] CPUs.
      
      Basically it saves/restores ACX register, which is part of the SMARTMIPS
      ASE, when needed. This patch does *not* add any support for Smartmips MMU
      features.
      
      Futhermore this patch does not add explicit support for 4KS[CD] CPUs since
      they are respectively mips32 and mips32r2 compliant.  So with the current
      processor configuration, a platform that has such CPUs needs to select
      both configs:
      
      	CPU_HAS_SMARTMIPS
      	SYS_HAS_CPU_MIPS32_R[12]
      
      This is due to the processor configuration which is mixing up all the
      architecture variants and the processor types.
      
      The drawback of this, is that we currently pass '-march=mips32' option to
      gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This
      can lead to a kernel image a little bit bigger than required.

      [MIPS] Load modules to CKSEG0 if CONFIG_BUILD_ELF64=n · 656be92f
      Atsushi Nemoto authored
      This is a patch to load 64-bit modules to CKSEG0 so that can be
      compiled with -msym32 option.  This makes each module ~10% smaller.
      
      * introduce MODULE_START and MODULE_END
      * custom module_alloc()
      * PGD for modules
      * change XTLB refill handler synthesizer
      * enable -msym32 for modules again
        (revert ca78b1a5c6a6e70e052d3ea253828e49b5d07c8a)
      
      New XTLB refill handler looks like this:
