2005-10-10powerpc: Fix compilation for 32-bit configsPaul Mackerras2-22/+5
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Fix off-by-one error in prom_init.cPaul Mackerras1-1/+1
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 iseries to compile with ARCH=powerpcPaul Mackerras3-13/+10
This moves the Device_List member from struct device_node to struct pci_dn, which cleans up the device_node and makes the code a little simpler. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Get 64-bit configs to compile with ARCH=powerpcPaul Mackerras16-77/+1546
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 Mackerras3-4/+5
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 Mackerras2-11/+11
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 Mackerras2-65/+10
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 Mackerras1-41/+17
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Make prom_init.c suitable for both 32-bit and 64-bitPaul Mackerras1-1/+1
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.SPaul Mackerras7-4/+4109
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 Mackerras2-127/+345
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Use arch/powerpc/mm and arch/powerpc/lib for 64-bitPaul Mackerras4-24/+143
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>
2005-10-10powerpc: Use reg.h instead of processor.h when we just want reg namesPaul Mackerras6-12/+7
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: Merge Kconfig.debugPaul Mackerras1-3/+58
This merges in the ppc64 bits into arch/powerpc/Kconfig.debug Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: rename powermac files to remove pmac_ prefixPaul Mackerras14-7/+6
Since the files are now in arch/powerpc/platforms/powermac, the pmac_ prefix that they had is redundant. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10ppc64: Use SPRN_ prefix for special purpose register namesPaul Mackerras2-112/+112
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 Mackerras12-53/+10
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Merge arch/ppc64/mm to arch/powerpc/mmPaul Mackerras20-1288/+39
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 Mackerras24-269/+129
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 Mackerras3-302/+4
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 Mackerras5-0/+5
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 Mackerras2-100/+100
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 Mackerras1-0/+1
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 Mackerras1-0/+1
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 Mackerras2-159/+35
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 Mackerras1-1/+2
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 Mackerras1-0/+274
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Remove 64-bit cpu support from ppc32.Paul Mackerras2-153/+11
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 Mackerras10-700/+509
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 Mackerras8-48/+5817
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 Mackerras2-100/+30
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 Mackerras1-1/+0
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 Mackerras2-3/+3
... and remove the exports from ppc_ksyms.c. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-01powerpc: make iSeries bootStephen Rothwell2-3/+3
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 Rothwell7-205/+211
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 Rothwell4-13/+12
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-01powerpc: merge idle_power4.S and trapc.sStephen Rothwell21-921/+563
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 Mackerras5-15/+24
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.

2005-09-28[PATCH] ppc64: More hugepage fixesBenjamin Herrenschmidt2-4/+5
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 Blanchard1-0/+1
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 stultz1-3/+0
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.
