2016-11-23arm64: Remove I-cache invalidation from flush_cache_range()Catalin Marinas
The flush_cache_range() function (similarly for flush_cache_page()) is called when the kernel is changing an existing VA->PA mapping range to either a new PA or to different attributes. Since ARMv8 has PIPT-like D-caches, this function does not need to perform any D-cache maintenance. The I-cache maintenance is already handled via set_pte_at() and flush_cache_range() cannot anyway guarantee that there are no cache lines left after invalidation due to the speculative loads. This patch makes flush_cache_range() a no-op. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2016-11-23x86/mce: Include the PPIN in MCE records when availableTony Luck
Intel Xeons from Ivy Bridge onwards support a processor identification number set in the factory. To the user this is a handy unique number to identify a particular CPU. Intel can decode this to the fab/production run to track errors. On systems that have it, include it in the machine check record. I'm told that this would be helpful for users that run large data centers with multi-socket servers to keep track of which CPUs are seeing errors.

2016-11-23powerpc/32: Change the stack protector canary value per taskChristophe Leroy
Partially copied from commit df0698be14c66 ("ARM: stack protector: change the canary value per task") A new random value for the canary is stored in the task struct whenever a new task is forked. This is meant to allow for different canary values per task. On powerpc, GCC expects the canary value to be found in a global variable called __stack_chk_guard. So this variable has to be updated with the value stored in the task struct whenever a task switch occurs. Because the variable GCC expects is global, this cannot work on SMP unfortunately. So, on SMP, the same initial canary value is kept throughout, making this feature a bit less effective although it is still useful.

2016-11-23powerpc/kprobes: Invoke handlers directlyNaveen N. Rao
Invoke the kprobe handlers directly rather than through notify_die(), to reduce path taken for handling kprobes. Similar to commit 6f6343f53d13 ("kprobes/x86: Call exception handlers directly from do_int3/do_debug"). While at it, rename post_kprobe_handler() to kprobe_post_handler() for more uniform naming.
