powerpc: Update compat_arch_ptrace

2010-12-09T04:35:32+00:00

Update compat_arch_ptrace to follow recent changes in PTRACE_GET_DEBUGREG and the addition of PPC_PTRACE_{GETHWDBGINFO|{SET|DEL}HWDEBUG}. The latter three can be forwarded to arch_ptrace unchanged. Signed-off-by: Andreas Schwab Signed-off-by: Benjamin Herrenschmidt

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

powerpc: Fix ptrace compat wrapper for FPU register access

2009-04-07T05:19:00+00:00

The ptrace compat wrapper mishandles access to the fpu registers. The PTRACE_PEEKUSR and PTRACE_POKEUSR requests miscalculate the index into the fpr array due to the broken FPINDEX macro. The PPC_PTRACE_PEEKUSR_3264 request needs to use the same formula that the native ptrace interface uses when operating on the register number (as opposed to the 4-byte offset). The PPC_PTRACE_POKEUSR_3264 request didn't take TS_FPRWIDTH into account. Signed-off-by: Andreas Schwab Signed-off-by: Michael Neuling Signed-off-by: Paul Mackerras

powerpc: Correctly hookup PTRACE_GET/SETVSRREGS for 32 bit processes

2008-07-30T05:26:54+00:00

Fix bug where PTRACE_GET/SETVSRREGS are not connected for 32 bit processes. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc: Add macros to access floating point registers in thread_struct.

2008-07-01T01:28:43+00:00

We are going to change where the floating point registers are stored in the thread_struct, so in preparation add some macros to access the floating point registers. Update all code to use these new macros. Signed-off-by: Michael Neuling Signed-off-by: Paul Mackerras

Revert "[POWERPC] Add compat handler for PTRACE_GETSIGINFO"

2008-04-24T04:05:15+00:00

This reverts commit e4cc58944c1e2ce41e3079d4eb60c95e7ce04b2b, as requested by Roland McGrath, because compat_ptrace_request (added in commit e16b27816462de700f9508d86954410c41105dc2, "ptrace: compat_ptrace_request siginfo") now handles this case. Signed-off-by: Paul Mackerras

[POWERPC] Add compat handler for PTRACE_GETSIGINFO

2008-04-20T03:03:36+00:00

Current versions of gdb require a working implementation of PTRACE_GETSIGINFO for proper watchpoint support. Since struct siginfo contains pointers it must be converted when passed to a 32-bit debugger. Signed-off-by: Andreas Schwab Signed-off-by: Paul Mackerras

[POWERPC] Use regset code for compat PTRACE_REGS calls

2008-02-07T09:40:21+00:00

This cleans up the 32-bit ptrace syscall support to use user_regset calls to get at the register data for PTRACE_*REGS* calls. Signed-off-by: Roland McGrath Signed-off-by: Paul Mackerras

[POWERPC] Use generic compat_sys_ptrace
