Pull perf tooling fixes from Arnaldo Carvalho de Melo:

 - Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.

 - Set opt->set in libsubcmd's OPT_CALLBACK_SET(). This fixes
   'perf record --switch-output-event event-name' usage"

Pull x86 fixes from Thomas Gleixner:
 "A pile of fixes for x86:

   - Fix the I/O bitmap invalidation on XEN PV, which was overlooked in
     the recent ioperm/iopl rework. This caused the TSS and XEN's I/O
     bitmap to get out of sync.

   - Use the proper vectors for HYPERV.

   - Make disabling of stack protector for the entry code work with GCC
     builds which enable stack protector by default. Removing the option
     is not sufficient, it needs an explicit -fno-stack-protector to
     shut it off.

   - Mark check_user_regs() noinstr as it is called from noinstr code.
     The missing annotation causes it to be placed in the text section
     which makes it instrumentable.

   - Add the missing interrupt disable in exc_alignment_check()

   - Fixup a XEN_PV build dependency in the 32bit entry code

   - A few fixes to make the Clang integrated assembler happy

   - Move EFI stub build to the right place for out of tree builds

   - Make prepare_exit_to_usermode() static. It's not longer called from
     ASM code"

Pull timer fixes from Thomas Gleixner:
 "Two fixes for the timer wheel:

   - A timer which is already expired at enqueue time can set the
     base->next_expiry value backwards. As a consequence base->clk can
     be set back as well. This can lead to timers expiring early. Add a
     sanity check to prevent this.

   - When a timer is queued with an expiry time beyond the wheel
     capacity then it should be queued in the bucket of the last wheel
     level which is expiring last.

     The code adjusted the expiry time to the maximum wheel capacity,
     which is only correct when the wheel clock is 0. Aside of that the
     check whether the delta is larger than wheel capacity does not
     check the delta, it checks the expiry value itself. As a result
     timers can expire at random.

     Fix this by checking the right variable and adjust expiry time so
     it becomes base->clock plus capacity which places it into the
     outmost bucket in the last wheel level"
