2012-07-28ARM: 7475/1: sys_trace: allow all syscall arguments to be updated via ptraceWill Deacon
Prior to syscall invocation, __sys_trace only reloads r0-r3 from the kernel stack, preventing the debugger from updating arguments 5-7 when signalled via ptrace. This patch updates the code to reload r0-r6, updating arguments 5 and 6 on the stack (argument 7 is only used by OABI indirect syscalls and can remain in a register).

2012-07-27powerpc/ftrace: Trace function graph entry before updating indexSteven Rostedt
As Colin Cross ported my x86 change to ARM, he also pointed out that powerpc is also behind in this fix. The commit 722b3c746953 "ftrace/graph: Trace function entry before updating index" fixes an issue with function graph tracing for x86, where if the called entry function decides not to trace interrupts, it can fail the check if an interrupt comes in just after the curr_ret_stack is updated. The solution is to call the entry function first, then update the curr_ret_stack if the entry function wants to be traced.
