* powerpc: Set entry point and text address in linker scriptMichael Ellerman2005-11-031-4/+1
| | | | | | | | | | | | | | | | 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. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

* powerpc: Merge xmonPaul Mackerras2005-10-281-1/+1
| | | | | | | | | | | 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 The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

* ppc64: Minor compilation fixesPaul Mackerras2005-10-201-1/+1
| | | | | | | | This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of sys32_ to compat_sys_ in the ppc64 syscall table, and removes a reference to a non-existent arch/powerpc/xmon/Makefile. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras2005-10-181-1/+0
| | | | | | | | This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: fix uname -mStephen Rothwell2005-10-131-0/+2
| | | | | | | It will now give ppc64 on 64bit platforms and ppc on 32bit platforms. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* powerpc: Make building the boot image work for both 32-bit and 64-bitPaul Mackerras2005-10-111-1/+8
| | | | | | | | | At the moment we don't have a merged arch/powerpc/boot, so we build the boot images in arch/ppc/boot and arch/ppc64/boot. Unfortunately the makefile targets are different in those two directories, so this makes a change to accommodate both for the moment. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.SPaul Mackerras2005-10-101-2/+1
| | | | | | | | | The system call table has been consolidated into systbl.S. We have separate 32-bit and 64-bit versions of entry.S and misc.S since the code is mostly sufficiently different to be not worth merging. There are some common bits that will be extracted in future.

* powerpc: Use arch/powerpc/mm and arch/powerpc/lib for 64-bitPaul Mackerras2005-10-101-9/+6
| | | | | | | This also puts a copy of indirect_pci.c in arch/powerpc/sysdev so that we don't need to build in arch/ppc/syslib. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Rename files to have consistent _32/_64 suffixesPaul Mackerras2005-10-101-1/+1
| | | | | | | | 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: make iSeries buildStephen Rothwell2005-10-011-11/+16
| | | | | | | | Merge vmlinux.lds.S. Also remove arch/powerpc/kernel/vmlinux.lds which is a generated file. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

* powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras2005-09-261-0/+222
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.
