This refactors the only user of init_timer_pinned_deferrable() to use the new timer_setup() and from_timer(). Adds a pointer back to the policy, and drops the definition of init_timer_pinned_deferrable().

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new from_timer() helper and passing the timer pointer explicitly. Since this special timer is on the stack, it needs to have a wrapper structure to carry state once .data is eliminated.

Pull percpu fixes from Tejun Heo: "Rather important fixes this time. - The new percpu area allocator had a subtle bug in how it iterates the memory regions and could skip viable areas, which led to allocation failures for module static percpu variables. Dennis fixed the bug and another non-critical one in stat calculation. - Mark noticed that the generic implementations of percpu local atomic reads aren't properly protected against irqs and there's a (slim) chance for split reads on some 32bit systems. Generic implementations are updated to disable irq when read size is larger than ulong size. This may have made some 32bit archs which can do atomic local 64bit accesses generate sub-optimal code. We need to find them out and implement arch-specific overrides" * 'for-4.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: fix iteration to prevent skipping over block percpu: fix starting offset for chunk statistics traversal percpu: make this_cpu_generic_read() atomic w.r.t. interrupts

Merge tag 'driver-core-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core fixes from Greg KH: "Here are a few small fixes for 4.14-rc4. The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one straggler made it in through some other tree (odds are, one of mine...) So there's a simple removal of the last user, and then finally the macro is removed from the tree. There's a fix for old crazy udev instances that insist on reloading a module when it is removed from the kernel due to the new uevents for bind/unbind. This fixes the reported regression, hopefully some year in the future we can drop the workaround, once users update to the latest version, but I'm not holding my breath. And then there's a build fix for a linker warning, and a buffer overflow fix to match the PCI fixes you took through the PCI tree in the same area. All of these have been in linux-next for a few weeks while I've been traveling, sorry for the delay" * tag 'driver-core-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: driver core: remove DRIVER_ATTR fpga: altera-cvp: remove DRIVER_ATTR() usage driver core: platform: Don't read past the end of "driver_override" buffer base: arch_topology: fix section mismatch build warnings driver core: suppress sending MODALIAS in UNBIND uevents

Pull timer fixes from Thomas Gleixner: "This adds a new timer wheel function which is required for the conversion of the timer callback function from the 'unsigned long data' argument to 'struct timer_list *timer'. This conversion has two benefits: 1) It makes struct timer_list smaller 2) Many callers hand in a pointer to the timer or to the structure containing the timer, which happens via type casting both at setup and in the callback. This change gets rid of the typecasts. Once the conversion is complete, which is planned for 4.15, the old setup function and the intermediate typecast in the new setup function go away along with the data field in struct timer_list. Merging this now into mainline allows a smooth queueing of the actual conversion in the affected maintainer trees without creating dependencies" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: um/time: Fixup namespace collision timer: Prepare to change timer callback argument type

kernel_waitid() can return a PID, an error or 0. rusage is filled in the first case and waitid(2) rusage should've been copied out exactly in that case, *not* whenever kernel_waitid() has not returned an error. Compat variant shares that braino; none of kernel_wait4() callers do, so the below ought to fix it.

Currently we use current_stack_pointer() function to get the value of the stack pointer register. Since commit: f5caf621 ("x86/asm: Fix inline asm call constraints for Clang") ... we have a stack register variable declared. It can be used instead of current_stack_pointer() function which allows to optimize away some excessive "mov %rsp, %<dst>" instructions: -mov %rsp,%rdx -sub %rdx,%rax -cmp $0x3fff,%rax -ja ffffffff810722fd <ist_begin_non_atomic+0x2d> +sub %rsp,%rax +cmp $0x3fff,%rax +ja ffffffff810722fa <ist_begin_non_atomic+0x2a> Remove current_stack_pointer(), rename __asm_call_sp to current_stack_pointer and use it instead of the removed function.

Some routines in mem_encrypt.c are called very early in the boot process, e.g. sme_encrypt_kernel(). When CONFIG_TRACE_BRANCH_PROFILING=y is defined the resulting branch profiling associated with the check to see if SME is active results in a kernel crash. Disable branch profiling for mem_encrypt.c by defining DISABLE_BRANCH_PROFILING before including any header files.

Merge branch 'fixes-v4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull keys fixes from James Morris: "Notable here is a rewrite of big_key crypto by Jason Donenfeld to address some issues in the original code. From Jason's commit log: "This started out as just replacing the use of crypto/rng with get_random_bytes_wait, so that we wouldn't use bad randomness at boot time. But, upon looking further, it appears that there were even deeper underlying cryptographic problems, and that this seems to have been committed with very little crypto review. So, I rewrote the whole thing, trying to keep to the conventions introduced by the previous author, to fix these cryptographic flaws." There has been positive review of the new code by Eric Biggers and Herbert Xu, and it passes basic testing via the keyutils test suite. Eric also manually tested it. Generally speaking, we likely need to improve the amount of crypto review for kernel crypto users including keys (I'll post a note separately to ksummit-discuss)" * 'fixes-v4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: security/keys: rewrite all of big_key crypto security/keys: properly zero out sensitive key material in big_key KEYS: use kmemdup() in request_key_auth_new() KEYS: restrict /proc/keys by credentials at open time KEYS: reset parent each time before searching key_user_tree KEYS: prevent KEYCTL_READ on negative key KEYS: prevent creating a different user's keyrings KEYS: fix writing past end of user-supplied buffer in keyring_read() KEYS: fix key refcount leak in keyctl_read_key() KEYS: fix key refcount leak in keyctl_assume_authority() KEYS: don't revoke uninstantiated key in request_key_auth_new() KEYS: fix cred refcount leak in request_key_auth_new()
