2007-12-06[POWERPC] Fix swapper_pg_dir size when CONFIG_PTE_64BIT=y on FSL_BOOKEKumar Gala1-1/+1
The size of swapper_pg_dir is 8k instead of 4k when using 64-bit PTEs (CONFIG_PTE_64BIT). This was reported by Cedric Hombourger <chombourger@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-11[POWERPC] Use PAGE_OFFSET to tell if an address is user/kernel in SW TLB handlersKumar Gala1-7/+4
Move to using PAGE_OFFSET instead of TASK_SIZE or KERNELBASE value on 6xx/40x/44x/fsl-booke to determine if the faulting address is a kernel or user space address. This mimics how the macro is_kernel_addr() works. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-09-19[POWERPC] Remove cmd_line from head*.SStephen Rothwell1-8/+0
It is just a C char array, so declare it thusly. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-09-14[POWERPC] Fix modpost warnings from head*.S on ppc32Kumar Gala1-3/+3
We get warnings like the following from the various ppc32 head*.S files: WARNING: vmlinux.o(.text+0x358): Section mismatch: reference to .init.text:early_init (between 'skpinv' and 'interrupt_base') WARNING: vmlinux.o(.text+0x380): Section mismatch: reference to .init.text:machine_init (between 'skpinv' and 'interrupt_base') WARNING: vmlinux.o(.text+0x384): Section mismatch: reference to .init.text:MMU_init (between 'skpinv' and 'interrupt_base') WARNING: vmlinux.o(.text+0x3aa): Section mismatch: reference to .init.text:start_kernel (between 'skpinv' and 'interrupt_base') WARNING: vmlinux.o(.text+0x3ae): Section mismatch: reference to .init.text:start_kernel (between 'skpinv' and 'interrupt_base') Added a .text.head section simliar to what other architectures do since modpost already excludes this from its warnings.

2007-02-13[POWERPC] 85xx: Drop use of SYNC macro in head_fsl_booke.SBecky Bruce1-2/+0
Eliminate needless invocation of the SYNC macro (which always evaluates to nothing on BookE) from head_fsl_booke.S (for both arch/ppc & arch/powerpc). Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-02-12[POWERPC] 85xx: Don't write reserved values to MAS1[TSIZE]Becky Bruce1-1/+4
Some of the current tlbwe instructions early on in head_fsl_booke.S take advantage of unarchitected behavior that allows the writing of reserved values to the TSIZE field. This patch corrects that, as well as an error where an uninitialized (by linux) value was written into a MAS register and used for a tlbwe. Correct this for both arch/ppc and arch/powerpc.

2006-02-10[PATCH] powerpc: trivial: modify comments to refer to new location of filesJon Mason1-2/+0
This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-10[PATCH] powerpc/ppc: Add missing isyncs in head_fsl_booke.SBecky Bruce1-0/+4
The e500 core reference manual indicates that isync is required after mtmsr(DE bit) and mtspr DBCR0. Add isyncs to make the code conform to the spec.

2005-10-01powerpc: merge idle_power4.S and trapc.sStephen Rothwell1-12/+12
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>
2005-09-26powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras1-0/+1058
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.
