2005-10-10ppc64: Use SPRN_ prefix for special purpose register namesPaul Mackerras
Now that we are using the merged reg.h we have to use the SPRN_xxx names rather than the xxx names. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: move pSeries files to arch/powerpc/platforms/pseriesPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Merge arch/ppc64/mm to arch/powerpc/mmPaul Mackerras
This moves the remaining files in arch/ppc64/mm to arch/powerpc/mm, and arranges that we use them when compiling with ARCH=ppc64. 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>
2005-10-10ppc64: Use the merged lmb routinesPaul Mackerras
The only real change here is that lmb_enforce_memory_limit now takes the memory_limit as a parameter instead of as a global variable. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Make some #includes explicit.Paul Mackerras
In preparation for merging processor.h, this adds some explicit but won't be after the merge. 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: Fix idle.c compile warningPaul Mackerras
This fixes a compile warning when using arch/ppc/kernel/idle.c in a merged (ARCH=powerpc) kernel. 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 lmb.c and make MM initialization use it.Paul Mackerras
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. 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>
2005-10-04ppc32: remove obsolete klock_info definitionPaul Mackerras
klock_info isn't used or referenced anywhere else in the kernel. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-04ppc32: export a few more things where they are definedPaul Mackerras
... and remove the exports from ppc_ksyms.c. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-01powerpc: make iSeries bootStephen Rothwell
Now that we use the device tree, it helps to build it in. It helps to links the kernel at the correct address. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
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>

2005-09-30ppc64 iseries: move some iSeries include filesStephen Rothwell
These files are only referenced from within arch/powerpc/platforms/iseries, so move them there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-09-28[PATCH] ppc64: More hugepage fixesBenjamin Herrenschmidt
My previous patch fixing invalidation of huge PTEs wasn't good enough, we still had an issue if a PTE invalidation batch contained both small and large pages. This patch fixes this by making sure the batch is flushed if the page size fed to it changes.

2005-09-28[PATCH] ppc64: Add missing barrier() in kexec codeAnton Blanchard
Mikey and I were testing kexec and hit a lockup. It turns out gcc 4.0 optimises the kexec_prepare_cpus loop so we avoid reloading paca.hw_cpu_id. A gcc barrier() fixes the problem.

2005-09-28[PATCH] x86-64: Fix bad assumption that dualcore cpus have synced TSCsjohn stultz
This should resolve the issue seen in bugme bug #5105, where it is assumed that dualcore x86_64 systems have synced TSCs. This is not the case, and alternate timesources should be used instead. For more details, see: http://bugzilla.kernel.org/show_bug.cgi?id=5105 Andi's earlier concerns that the TSCs should be synced on dualcore systems have been resolved by confirmation from AMD folks that they can be unsynced.

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.

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>
2005-09-28[PATCH] powerpc: merged asm/cputable.hKumar Gala
Merged cputable.h between ppc32 and ppc64. In doing this removed support for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they dont compile correctly. C code should use cpu_has_feature(). This is based on Arnd Bergmann's initial patch. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-28ppc64 iSeries: use device_node instead of iSeries_Device_nodeStephen Rothwell
