charset=us-ascii Content-Disposition: inline Hi Linus, This pull request 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.
