* ppc64: Change ppc_md.get_cpuinfo to ppc_md.show_cpuinfoPaul Mackerras2005-10-201-2/+2
| | | | | | | ... for consistency with ppc32; also add in ppc32's show_percpuinfo function. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]David Gibson2005-10-203-3/+114
| | | | | | | | | | | | | | This patches the ppc32 and ppc64 versions of the headers and .c files with helper functions for manipulating the performance counting hardware. As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon". Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

* powerpc: Merge time.c and asm/time.h.Paul Mackerras2005-10-205-12/+1007
| | | | | | | | | | We now use the merged time.c for both 32-bit and 64-bit compilation with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32. This removes setup_default_decr (folds its function into time_init) and moves wakeup_decrementer into time.c. This also makes an asm-powerpc/rtc.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Move ptrace32.c from arch/ppc64 to arch/powerpcPaul Mackerras2005-10-203-2/+452

| * powerpc: change sys32_ to compat_sys_Stephen Rothwell2005-10-184-242/+128
| | | | | | | | | | | | | | | | | | This allows us to get rid of one type of entry in systbl.S. In passing we remove the duplicate compat_sys_getdents and compat_sys_utimes for which there are generic versions. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* | powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras2005-10-185-14/+14
|/ | | | | | | | 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>

* [PATCH] powerpc: Another maple merge tree fixDavid Gibson2005-10-171-3/+1
| | | | | | | | | With ARCH=powerpc, a spurious ifdef in prom_init prevented the seconday hold loop being correctly copied down on Maple. With this patch, Maple boots with ARCH=powerpc Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Fix use of LOADBASE in merge treeDavid Gibson2005-10-171-2/+2
| | | | | | | | | | The merge-tree version of LOADBASE actually loads the whole given address from the toc for ppc64. The matching OFF macro adjust for this, using an offset of 0 for ppc64, but we weren't using that in power4_idle.

* [PATCH] powerpc: replace use of _GLOBAL with .globlKumar Gala2005-10-173-18/+33

* powerpc: Initialize btext subsystem later, after prom_initPaul Mackerras2005-10-173-99/+4
| | | | | | | | | | | | We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: Paul Mackerras <paulus@samba.org>

* powerpc: Move default hash table size calculation to hash_utils_64.cPaul Mackerras2005-10-121-20/+0
| | | | | | | | | 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>
* ppc64: Use merged versions of init_task.c and process.c.Paul Mackerras2005-10-111-1/+1
| | | | | | | These two files are now built in arch/powerpc/kernel instead of arch/ppc64/kernel. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc: Various minor compile fixesPaul Mackerras2005-10-112-2/+11
| | | | | | | | | | | | 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>
* powerpc: Remove debug messages from setup_64.cPaul Mackerras2005-10-111-16/+0
| | | | | | | 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>

* powerpc: Fix off-by-one error in prom_init.cPaul Mackerras2005-10-101-1/+1
| | | | | | | This was preventing us from recognizing that we did actually instantiate RTAS successfully on pSeries. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Get 64-bit configs to compile with ARCH=powerpcPaul Mackerras2005-10-107-69/+1382
| | | | | | | | 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: move lparmap.c to arch/powerpc/kernelPaul Mackerras2005-10-102-2/+34
| | | | | | | 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>
* powerpc: Fix bug caused by negation of 64-bit reloc_offset valuePaul Mackerras2005-10-102-11/+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>
* powerpc: Reduce the 32/64-bit diffs in vmlinux.lds.SPaul Mackerras2005-10-101-65/+9

* powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.SPaul Mackerras2005-10-106-2/+4108
| | | | | | | | | 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 reg.h instead of processor.h when we just want reg namesPaul Mackerras2005-10-104-6/+6
| | | | | | | 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 Mackerras2005-10-103-2/+2
| | | | | | | | 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: Use SPRN_xxx rather than xxx for SPR numbersPaul Mackerras2005-10-101-98/+98
| | | | | | | | | | 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>
* powerpc: Define a _sdata symbolPaul Mackerras2005-10-061-0/+1

* powerpc: Merge traps.c a bit morePaul Mackerras2005-10-062-159/+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>

* powerpc: Remove 64-bit cpu support from ppc32.Paul Mackerras2005-10-061-143/+5
| | | | | | | | 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>
* powerpc: Merge in the ppc64 version of the prom code.Paul Mackerras2005-10-067-43/+5811
| | | | | | | | | | | | | 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>
* powerpc: Define 32/64 bit asm macros and use them in fpu.SPaul Mackerras2005-10-062-100/+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>
