      [POWERPC] DEBUG_PAGEALLOC for 32-bit · 88df6e90
      Benjamin Herrenschmidt authored
      
      
      Here's an implementation of DEBUG_PAGEALLOC for ppc32. It disables BAT
      mapping and is only tested with Hash table based processor though it
      shouldn't be too hard to adapt it to others.

      [PATCH] ppc64: support 64k pages · 3c726f8d
      Benjamin Herrenschmidt authored
      
      
      Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel
      base page size to 64K.  The resulting kernel still boots on any
      hardware.  On current machines with 4K pages support only, the kernel
      will maintain 16 "subpages" for each 64K page transparently.
      
      Note that while real 64K capable HW has been tested, the current patch
      will not enable it yet as such hardware is not released yet, and I'm
      still verifying with the firmware architects the proper to get the
      information from the newer hypervisors.

      powerpc: Merge lmb.c and make MM initialization use it. · 7c8c6b97
      Paul Mackerras authored
      
      
      This also creates merged versions of do_init_bootmem, paging_init
      and mem_init and moves them to arch/powerpc/mm/mem.c.  It gets rid
      of the mem_pieces stuff.
      
      I made memory_limit a parameter to lmb_enforce_memory_limit rather
      than a global referenced by that function.  This will require some
      small changes to ppc64 if we want to continue building ARCH=ppc64
      using the merged lmb.c.

      powerpc: Merge enough to start building in arch/powerpc. · 14cf11af
      Paul Mackerras authored
      
      
      This creates the directory structure under arch/powerpc and a bunch
      of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
      arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
      to build a 32-bit powermac kernel with ARCH=powerpc.
      
      For now we are getting some unmerged files from arch/ppc/kernel and
      arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
      to files in those directories and files outside arch/powerpc.
      
      The boot directory is still not merged.  That's going to be interesting.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
