2005-10-13powerpc: create 32 bit LOADADDR macroStephen Rothwell
and use it in misc_32.S Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-13powerpc: consolidate cputable.cStephen Rothwell
Also simplify arch/ppc64/kernel/Makefile Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-12powerpc: Bring in some changes made to arch/ppc and include/asm-ppc64Paul Mackerras
Recent commits upstream have changed files which are currently duplicated in arch/powerpc and include/asm-powerpc. This updates them with the corresponding changes. 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>

2005-10-10powerpc: 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: make process.c suitable for both 32-bit and 64-bitPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Merged processor.h.Paul Mackerras
This adds register definitions from the ppc64 processor.h to reg.h, and makes a single merged processor.h. I moved __is_processor from the ppc64 system.h to the merged reg.h along with the PVR register constants. 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: 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>

2005-09-28[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>
2005-09-28[PATCH] powerpc: merge byteorder.hBecky Bruce
powerpc: Merge byteorder.h Essentially adopts the 64-bit version of this file. The 32-bit version had been using unsigned ints for arguments/return values that were actually only 16 bits - the new file uses __u16 for these items as in the 64-bit version of the header. The order of some of the asm constraints in the 64-bit version was slightly different than the 32-bit version, but they produce identical code.

2005-09-28powerpc: Move iSeries_pci.c to powerpc/platform/iseriesStephen Rothwell
and rename it to pci.c. This also required moving arch/ppc64/kernel/pci.h into include/asm-powerpc (called ppc-pci.h. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-09-27powerpc: clean up after powermac build mergeStephen Rothwell
Complete moving arch/ppc64/kernel/mpic.h, include/asm-ppc/reg.h, include/asm-ppc64/kdebug.h and include/asm-ppc64/kprobes.h Add arch/powerpc/platforms/Makefile and use it from arch/powerpc/Makefile Introduce OLDARCH temporarily so we can point back to the originating architecture Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-25[PATCH] powerpc: merge semaphore.hBecky Bruce
powerpc: Merge semaphore.h Adopted the ppc64 version of semaphore.h. The 32-bit version used smp_wmb(), but recent updates to atomic.h mean this is no longer required. The 64-bit version made use of unlikely(), which has been retained in the combined version. This patch requires the recent atomic.h patch.

2005-09-25[PATCH] powerpc: Merge asm-ppc*/rwsem.hJon Loeliger
Merge asm-ppc*/rwsem.h into include/asm-powerpc. Removed smp_*mb() memory barriers from the ppc32 code as they are now burried in the atomic_*() functions as suggested by Paul, implemented by Arnd, and pushed out by Becky. I am not the droid you are looking for. This patch depends on Becky's atomic.h merge patch.

2005-09-25[PATCH] powerpc: merge atomic.h, memory.hBecky Bruce
powerpc: Merge atomic.h and memory.h into powerpc Merged atomic.h into include/powerpc. Moved asm-style HMT_ defines from memory.h into ppc_asm.h, where there were already HMT_defines; moved c-style HMT_ defines to processor.h. Renamed memory.h to synch.h to better reflect its contents.

2005-09-22[PATCH] powerpc: merged hw_irq.hKumar Gala
Merged hw_irq.h between ppc32 & ppc64. Added support to use the Book-E wrtee[i] instructions that allow modifying MSR[EE] atomically. Additionally, added get_irq_desc() macros to ppc32 to allow mask_irq(), unmask_irq(), and ack_irq() to be common between ppc32 & ppc64. Note: because 64-bit Book-E implementations only have a 32-bit MSR the macro's for Book-E need to come before the PPC64 macro's to ensure the right thing happends for 64-bit Book-E processors.

2005-09-22[PATCH] powerpc: Fix compiling of ppc32Kumar Gala
The merging of auxvec.h into asm-powerpc introduced the AT_SYSINFO_EHDR into the ppc32 build that is used for VDSO. However, we dont have VDSO support in the ppc32 tree at this time. Introducing this define causes a number of other things to get built with the assumption of VDSO, thus causing the compile errors for ppc32. Until we have VDSO on ppc32 we will leave AT_SYSINFO_EHDR a ppc64 only define. Signed-off-by: Kumar K. Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

ppc32/ppc64: Merge bug.h into include/asm-powerpc This patch merges bug.h into include/asm-powerpc. Changed the data structure for bug_entry such that line is always an int on both 32 and 64-bit platforms; removed casts to int from the 64-bit trap code to reflect this.

2005-09-21[PATCH] powerpc: Revised merge asm-ppc*/hardirq.hlinuxppc@jdl.com
This is a revised patch to merge asm-ppc*/hardirq.h. It removes some unnecessary #includes, but then requires the addition of #include <asm/irq.h> in PPC32's hw_irq.h much like ppc64 already does. Furthermore, several unnecessary #includes were removed from some ppc32 boards in order to break resulting bad #include cycles. Builds pSeries_defconfig and all ppc32 platforms except the already b0rken bseip.

Merged ppc_asm.h between ppc32 & ppc64. The majority of the file is common between the two architectures excluding how a single GPR is saved/restored and which GPRs are non-volatile.

2005-09-12[PATCH] ppc64: Add definitions for new PTRACE callsAnton Blanchard
- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is as follows: /* * Get or set a debug register. The first 16 are DABR registers and the * second 16 are IABR registers. */ #define PTRACE_GET_DEBUGREG 25 #define PTRACE_SET_DEBUGREG 26 DABR == data breakpoint and IABR = instruction breakpoint in IBM speak. We could split out the IABR into 2 more ptrace calls but I figured there was no need and 16 DABR registers should be more than enough (POWER4/POWER5 have one). - Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt find any standards on either of these so I copied what ia64 is doing.
