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>

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>

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>

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>

Also adds the definition of the _sdata symbol to the ppc64 vmlinux.lds.S. Signed-off-by: Paul Mackerras <paulus@samba.org>

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>

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>

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>

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>

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>

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>

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>

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>

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>

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>

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.

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>

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>

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>

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>

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>

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>

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>

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>

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.
