2005-10-12powerpc: Move default hash table size calculation to hash_utils_64.cPaul Mackerras
We weren't computing the size of the hash table correctly on iSeries because the relevant code in prom.c was #ifdef CONFIG_PPC_PSERIES. This moves the code to hash_utils_64.c, makes it unconditional, and cleans it up a bit. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-11ppc64: Use merged versions of init_task.c and process.c.Paul Mackerras
These two files are now built in arch/powerpc/kernel instead of arch/ppc64/kernel. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-11ppc: Various minor compile fixesPaul Mackerras
This fixes up a variety of minor problems in compiling with ARCH=ppc arising from using the merged versions of various header files. A lot of the changes are just adding #include <asm/machdep.h> to files that use ppc_md or smp_ops_t. This also arranges for us to use semaphore.c, vecemu.c, vector.S and fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-11powerpc: Remove debug messages from setup_64.cPaul Mackerras
A bunch of printks were left in arch/powerpc/kernel/setup_64.c from when I was chasing a bug. This removes them. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Fix compilation for 32-bit configsPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Fix off-by-one error in prom_init.cPaul Mackerras
This was preventing us from recognizing that we did actually instantiate RTAS successfully on pSeries. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Get 64-bit configs to compile with ARCH=powerpcPaul Mackerras
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>
2005-10-10powerpc: move lparmap.c to arch/powerpc/kernelPaul Mackerras
Since lparmap.s gets included in arch/powerpc/kernel/head_64.S, this avoids depending on a file in another directory. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Fix bug caused by negation of 64-bit reloc_offset valuePaul Mackerras
Although both ppc32 and ppc64 have a reloc_offset function, the ppc64 one produced the opposite sign to the ppc32 one. This standardizes on the ppc32 sign and fixes the merged 64-bit code to account for that. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Reduce the 32/64-bit diffs in vmlinux.lds.SPaul Mackerras
Also adds the definition of the _sdata symbol to the ppc64 vmlinux.lds.S. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Reduce the 32/64-bit differences in traps.cPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Make prom_init.c suitable for both 32-bit and 64-bitPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.SPaul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: make process.c suitable for both 32-bit and 64-bitPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Use reg.h instead of processor.h when we just want reg namesPaul Mackerras
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>
2005-10-10powerpc: Rename files to have consistent _32/_64 suffixesPaul Mackerras
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>
2005-10-10powerpc: Use SPRN_xxx rather than xxx for SPR numbersPaul Mackerras
This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to special purpose registers to SPRN_HID0, SPRN_SPRG3, etc. Using the SPRN_ symbols clutters the namespace less, and the forthcoming merge of asm/processor.h and asm/reg.h is going to remove the non-SPRN_ versions. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Define a _sdata symbolPaul Mackerras
This is needed by arch/powerpc/mm/mem.c now. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Merge traps.c a bit morePaul Mackerras
This reduces the differences between ppc32 and ppc64 in arch/powerpc/kernel/traps.c a bit further. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Use the merged of_device.c with ARCH=powerpcPaul Mackerras
Also compile btext.c with -fPIC; this was missed before. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Merge of_device.c and of_device.hPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Remove 64-bit cpu support from ppc32.Paul Mackerras
These days there is no good reason to run a ppc32 kernel on a 64-bit cpu, rather than a ppc64 kernel, so remove the config option and a bunch of code (and ifdefs) from head.S. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Merge in the ppc64 version of the prom code.Paul Mackerras
This brings in the ppc64 version of prom_init.c, prom.c and btext.c and makes them work for ppc32. This also brings in the new calling convention, where the first entry to the kernel (with r5 != 0) goes to the prom_init code, which then restarts from the beginning (with r5 == 0) after it has done its stuff. For now this also brings in the ppc32 version of setup.c. It also merges lmb.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Define 32/64 bit asm macros and use them in fpu.SPaul Mackerras
These macros help in writing assembly code that works for both ppc32 and ppc64. With this we now have a common fpu.S. This takes out load_up_fpu from head_64.S. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-01powerpc: make iSeries buildStephen Rothwell
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>
2005-10-01ppc64: simplify the build a littleStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-01powerpc: merge idle_power4.S and trapc.sStephen Rothwell
Use idle_power4.S from ppc64 as we are not going to support 32 bit power4 in the merged tree. Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-01powerpc: Get merged kernel to compile and run on 32-bit SMP powermac.Paul Mackerras
This updates the powermac SMP code to use the mpic driver instead of the openpic driver and fixes the SMP-dependent context switch code. We had a subtle bug where we were using interrupt numbers 256-259 for IPIs, but ppc32 had NR_IRQS = 256. Moved the IPIs down to use interrupt numbers 252-255 instead. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-30powerpc: more cleanup of powerpc/kernelStephen Rothwell

2005-09-28powerpc: Fixes to get the merged kernel to boot on powermac.Paul Mackerras
This merges ppc_ksyms.c, puts back the actual do_execve call in sys_execve, makes init_MMU call find_end_of_memory rather than ppc_md.find_end_of_memory (every platform has a device tree with a /memory node now, right?) and fixes some problems with the mpic initialization on newworld powermacs. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-28[PATCH] ppc32: make cur_cpu_spec a single pointer instead of an arrayKumar Gala
Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs. Additionally, made call_setup_cpu check to see if the cpu_setup pointer is NULL or not before calling the function. This lets remove the dummy cpu_setup calls that just return. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-26powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras
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.

2005-09-21[PATCH] powerpc: Move arch/ppc*/kernel/vecemu.c to arch/powerpcStephen Rothwell
This file is the same in both architectures so create arch/powerpc/kernel and move it there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
