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" * tag 'alpha-for-v7.3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/lindholm/alpha: alpha: read $gp and $sp explicitly for clang alpha: pass -Wa,-mev6 only when using GNU as alpha: annotate hardirqs-off on IPL 7 interrupt entry alpha: run the remote RTC access in a worker, not an IPI callback alpha: don't leak hardware-fabricated FP exception bits to user space alpha: fix ieee_swcr_to_fpcr setting FPCR_DNOD unconditionally alpha: enable lockdep hardirq state tracking alpha: use raw spinlocks for low-level platform locks alpha: provide ftrace return address support for lockdep alpha: make irqflags helpers operate on IPL state alpha: add ARCH_STACKWALK-based stacktrace support alpha: enable regset-based ptrace and core dumps alpha: marvel: Fix lock ordering in init_io7_irqs() alpha: marvel: Fix irq_set_status_flags to use correct IRQ number alpha: remove unnecessary architecture-specific <asm/device.h>
