arch: remove unused macro/function thread_saved_pc()

2017-06-28T23:13:57Z

The only user of thread_saved_pc() in non-arch-specific code was removed in commit 8243d5597793 ("sched/core: Remove pointless printout in sched_show_task()"). Remove the implementations as well. Some architectures use thread_saved_pc() in their arch-specific code. Leave their thread_saved_pc() intact.

Pull uaccess unification updates from Al Viro: "This is the uaccess unification pile. It's _not_ the end of uaccess work, but the next batch of that will go into the next cycle. This one mostly takes copy_from_user() and friends out of arch/* and gets the zero-padding behaviour in sync for all architectures. Dealing with the nocache/writethrough mess is for the next cycle; fortunately, that's x86-only. Same for cleanups in iov_iter.c (I am sold on access_ok() in there, BTW; just not in this pile), same for reducing __copy_... callsites, strn*... stuff, etc. - there will be a pile about as large as this one in the next merge window.

ARCv2: entry: save Accumulator register pair (r58:59) if present

2017-04-20T22:37:49Z

Accumulator is present in configs with FPU and/or DSP MPY (mpy > 6) Instead of doing this in pt_regs (and thus every kernel entry/exit), this could have been done in context switch (and for user task only) as currently kernel doesn't clobber these registers for its own accord. However we will soon start using 64-bit multiply instructions for kernel which can clobber these. Also gcc folks also plan to start using these as GPRs, hence better to always save/restore them Signed-off-by: Vineet Gupta
