powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00Z

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

powerpc: Add asm/syscall.h with the tracehook entry points

2008-07-28T06:30:49Z

Add asm/syscall.h for powerpc with all the required entry points. This will allow arch-independent tracing code for system calls. BenH: Fixed up use of regs->trap to properly mask low bit Signed-off-by: Roland McGrath Signed-off-by: Benjamin Herrenschmidt

powerpc: Add VSX context save/restore, ptrace and signal support

2008-07-01T01:28:50Z

This patch extends the floating point save and restore code to use the VSX load/stores when VSX is available. This will make FP context save/restore marginally slower on FP only code, when VSX is available, as it has to load/store 128bits rather than just 64bits. Mixing FP, VMX and VSX code will get constant architected state. The signals interface is extended to enable access to VSR 0-31 doubleword 1 after discussions with tool chain maintainers. Backward compatibility is maintained. The ptrace interface is also extended to allow access to VSR 0-31 full registers. Signed-off-by: Michael Neuling Signed-off-by: Paul Mackerras

[POWERPC] Set lower flag bits in regs->trap to indicate debug level exception

2008-05-14T12:31:37Z

We use the low bits of regs->trap as flag bits. We already indicate critical and machine check level exceptions via this mechanism. Extend it to indicate debug level exceptions. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

[POWERPC] Move stackframe definitions to common header

2008-04-18T05:37:18Z

This moves various definitions used all over the place to parse stack frames to ptrace.h so only one definition is needed. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Use generic compat_sys_ptrace

2008-02-07T09:40:21Z

This replaces powerpc's compat_sys_ptrace with a compat_arch_ptrace and enables the new generic definition of compat_sys_ptrace instead. Signed-off-by: Roland McGrath Signed-off-by: Paul Mackerras

Merge branch 'linux-2.6'

powerpc: arch_has_single_step

2008-01-30T12:30:51Z

This defines the new standard arch_has_single_step macro. It makes the existing set_single_step and clear_single_step entry points global, and renames them to the new standard names user_enable_single_step and user_disable_single_step, respectively.

[POWERPC] Reworking machine check handling and Fix 440/440A

2007-12-23T19:11:59Z

This adds a cputable function pointer for the CPU-side machine check handling. The semantic is still the same as the old one, the one in ppc_md. overrides the one in cputable, though ultimately we'll want to change that so the CPU gets first. This removes CONFIG_440A which was a problem for multiplatform kernels and instead fixes up the IVOR at runtime from a setup_cpu function. The "A" version of the machine check also tweaks the regs->trap value to differenciate the 2 versions at the C level. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Josh Boyer

[POWERPC] Uninline common ptrace bits

2007-06-14T12:29:57Z

This folds back the ptrace-common.h bits back into ptrace.c and removes that file. The FSL SPE bits from ptrace-ppc32.h are folded back in as well. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras
