Pull x86 acpi fixes from Thomas Gleixner: "This update deals with the fallout of the recent work to make cpuid/node mappings persistent. It turned out that the boot time ACPI based mapping tripped over ACPI inconsistencies and caused regressions. It's partially reverted and the fragile part replaced by an implementation which makes the mapping persistent when a CPU goes online for the first time" * 'x86-acpi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: acpi/processor: Check for duplicate processor ids at hotplug time acpi/processor: Implement DEVICE operator for processor enumeration x86/acpi: Restore the order of CPU IDs Revert"x86/acpi: Enable MADT APIs to return disabled apicids" Revert "x86/acpi: Set persistent cpuid <-> nodeid mapping when booting"

Add a prototype of task_struct to fix below warning on arm64.
In file included from arch/arm64/kernel/probes/kprobes.c:19:0:
include/linux/kasan.h:81:132: error: 'struct task_struct' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
static inline void kasan_unpoison_task_stack(struct task_struct *task) {}
As same as other types (kmem_cache, page, and vm_struct) this adds a
prototype of task_struct data structure on top of kasan.h.
[arnd] A related warning was fixed before, but now appears in a
different line in the same file in v4.11-rc2. The patch from Masami
Hiramatsu still seems appropriate, so let's take his version.

Improve bpf_{prog,jit_binary}_{un,}lock_ro() by throwing a
one-time warning in case of an error when the image couldn't
be set read-only, and also mark struct bpf_prog as locked when
bpf_prog_lock_ro() was called.
Reason for the latter is that bpf_prog_unlock_ro() is called from
various places including error paths, and we shouldn't mess with
page attributes when really not needed.
For bpf_jit_binary_unlock_ro() this is not needed as jited flag
implicitly indicates this, thus for archs with ARCH_HAS_SET_MEMORY
we're guaranteed to have a previously locked image. Overall, this
should also help us to identify any further potential issues with
set_memory_*() helpers.

The check for duplicate processor ids happens at boot time based on the ACPI table contents, but the final sanity checks for a processor happen at hotplug time. At hotplug time, where the physical information is available, which might differ from the ACPI table information, a check for duplicate processor ids is missing. Add it to the hotplug checks and rename the function so it better reflects its purpose.
