      [PATCH] powerpc32: Set cpu explicitly in kernel compiles · f48b8296
      由 Olaf Hering 提交于 
      Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize
when a compiler is used that defaults to -mtune=power4. It inserts lots
of nops to please the 64bit cpu instruction scheduling. But all these nops
are not needed for 32bit kernels.

Example with SLES10 gcc 4.1.0 and arch/powerpc/configs/pmac32_defconfig:

                    vmlinux  vmlinux.strip  vmlinux.gz
 -O2                4980515     4187528      1846829
 -Os                4618801     3827084      1673333
 -O2 -mcpu=powerpc  4738851     3945868      1816253
 -Os -mcpu=powerpc  4532785     3741068      1664688

      powerpc: Don't compile in arch/ppc/kernel for 32-bit ARCH=powerpc · e7e2d2da
      由 Paul Mackerras 提交于 
      All of the things needed for 32-bit ARCH=powerpc builds have now
moved to arch/powerpc/kernel, so we don't need to go down into
arch/ppc/kernel any more, and we can remove the CONFIG_PPC_MERGE
conditional from arch/ppc/kernel/Makefile.

There were two files still referenced in the merge section of
arch/ppc/kernel/Makefile: ppc-stub.o, depending on CONFIG_KGDB,
and dma-mapping.o, depending on CONFIG_NOT_COHERENT_CACHE.  None
of the platforms currently in ARCH=powerpc have caches that
aren't coherent with DMA, but when we do get one we'll move
dma-mapping.c over.  As for CONFIG_KGDB, none of the Kconfig
files in the tree define it, so I'll let it languish for now.

      [PATCH] Fix building external modules on ppc32 · 70567293
      由 Andreas Gruenbacher 提交于 
      We are setting up sources for building external modules like this:

  /usr/src/linux-obj> # create a .config file
  /usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig
  /usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare
  /usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts
  /usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean

After that, external modules can be built with:

  /usr/src/module> make -C /usr/src/linux-obj M=$PWD

This fails for ppc32 because the `make clean' removes the
arch/powerpc/include directory.  This should be done in archmrproper
instead of in archclean.

      powerpc: Set entry point and text address in linker script · e19e4ab4
      由 Michael Ellerman 提交于 
      Currently we set the kernel entry point and the address of the text
section in the Makefile, using CONFIG_KERNEL_START.

But we've already got <asm/page.h> in the linker script, so we can just
use KERNELBASE directly. That means if we ever change KERNELBASE there's
one less place to change it.

And we can set the entry point with ENTRY().

There are zero differences from "readelf -a vmlinux" with or without this
patch.

      powerpc: Merge xmon · f78541dc
      由 Paul Mackerras 提交于 
      The merged version follows the ppc64 version pretty closely mostly,
and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version.
The main difference for ppc64 is that the 'p' command to call
show_state (which was always pretty dodgy) has been replaced by
the ppc32 'p' command, which calls a given procedure (so in fact
the old 'p' command behaviour can be achieved with 'p $show_state').

      powerpc: Merge enough to start building in arch/powerpc. · 14cf11af
      由 Paul Mackerras 提交于 
      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.

      kbuild: rename prepare to archprepare to fix dependency chain · 5bb78269
      由 Sam Ravnborg 提交于 
      When introducing the generic asm-offsets.h support the dependency
chain for the prepare targets was changed. All build scripts expecting
include/asm/asm-offsets.h to be made when using the prepare target would broke.
With the limited number of prepare targets left in arch Makefiles
the trivial solution was to introduce a new arch specific target: archprepare

The dependency chain looks like this now:

prepare
  |
  +--> prepare0
         |
         +--> archprepare
                |
		+--> scripts_basic
                +--> prepare1
                       |
                       +---> prepare2
                               |
                               +--> prepare3

So prepare 3 is processed before prepare2 etc.
This guaantees that the asm symlink, version.h, scripts_basic
are all updated before archprepare is processed.

prepare0 which build the asm-offsets.h file will need the
actions performed by archprepare.

The head target is now named prepare, because users scripts will most
likely use that target, but prepare-all has been kept for compatibility.
