Merge tag 'alpha-for-v7.3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/lindh...

Pull alpha updates from Magnus Lindholm:
 "This contains two fixes for Alpha floating-point exception handling,
  two clang-related fixes, the preparatory changes from the
  generic-entry series, an interrupt-entry lockdep fix, two Marvel/EV7
  IRQ fixes, an RTC fix, and one header cleanup.

  The generic-entry preparation adds regset-based ptrace and core dumps,
  ARCH_STACKWALK and lockdep hardirq-state tracking. These changes are
  useful independently and enable previously missing debugging
  facilities on Alpha.

  The final patch switching Alpha to GENERIC_ENTRY is intentionally not
  included in this pull request. I am deferring that change to allow
  further testing and to reduce the risk of conflicts with ongoing
  entry-path work elsewhere in the kernel"
