* powerpc: apply recent changes to merged codePaul Mackerras2005-10-30

* powerpc: Merge xmonPaul Mackerras2005-10-28
| | | | | | | | | | | 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 The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').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: Make single-stepping emulation (mostly) usable on 32-bitPaul Mackerras2005-10-28
| | | | | | | The sc instruction emulation can't be done the same way on 32-bit as 64-bit yet, but this should work OK. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc64: use mem_64.S from powerpc/libStephen Rothwell2005-10-27
| | | | | | and remove the same bits from ppc64/lib/string.S. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use usercopy_64.c from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to usercopy.c from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: user strcase.c from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to strcase.c from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use sstep.c from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to sstep.c from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use memcpy_64.S from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to mempcy.S from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use lockc.c from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is effectively the same as locks.c from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use copyuser_64.S from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to copyuser.S from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use copypage_64.S from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to copypage.S from ppc64/lib. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use e2a.c from powerpc/libStephen Rothwell2005-10-27
| | | | | | since it is identical to e2a.c from ppc64/lib Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ppc64: use checksum_64.S from powerpcStephen Rothwell2005-10-27
| | | | | | as it is identical to checksum.S from ppc64. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* powerpc: Fix a corner case in __div64_32Paul Mackerras2005-10-19
| | | | | | | | The code was incorrectly doing a division by 0 in the case where the denominator was 0x100000000 and the divisor was 0xffffffff. Thanks to Fred Liu of Motorola for pointing this out. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc32: use L1_CACHE_SHIFT/L1_CACHE_BYTESStephen Rothwell2005-10-16
| | | | | | instead of L1_CACHE_LINE_SIZE and LG_L1_CACHE_LINE_SIZE Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* powerpc: Get 64-bit configs to compile with ARCH=powerpcPaul Mackerras2005-10-10
| | | | | | | | This is a bunch of mostly small fixes that are needed to get ARCH=powerpc to compile for 64-bit. This adds setup_64.c from arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Use reg.h instead of processor.h when we just want reg namesPaul Mackerras2005-10-10
| | | | | | | Now that the register names and bit definitions are all in reg.h, use that instead of processor.h in assembly code in a few places. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Rename files to have consistent _32/_64 suffixesPaul Mackerras2005-10-10
| | | | | | | | This doesn't change any code, just renames things so we consistently have foo_32.c and foo_64.c where we have separate 32- and 64-bit versions. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras2005-09-26
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.
