      perf: Remove the nmi parameter from the swevent and overflow interface · a8b0ca17
      Peter Zijlstra 提交于
      The nmi parameter indicated if we could do wakeups from the current
      context, if not, we would set some state and self-IPI and let the
      resulting interrupt do the wakeup.
      
      For the various event classes:
      
        - hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from
          the PMI-tail (ARM etc.)
        - tracepoint: nmi=0; since tracepoint could be from NMI context.
        - software: nmi=[0,1]; some, like the schedule thing cannot
          perform wakeups, and hence need 0.
      
      As one can see, there is very little nmi=1 usage, and the down-side of
      not using it is that on some platforms some software events can have a
      jiffy delay in wakeup (when arch_irq_work_raise isn't implemented).
      
      The up-side however is that we can remove the nmi parameter and save a
      bunch of conditionals in fast paths.

      sparc: prepare kernel/ for unification · d670bd4f
      Sam Ravnborg 提交于
      o sparc32 files with identical names to sparc64 renamed to <name>_32.S
      o introduced a few Kconfig helpers to simplify Makefile logic
      o refactored Makefile to prepare for unification
        - use obj-$(CONFIG_SPARC32) for sparc32 specific files
        - use <name>_$(BITS) for files where sparc64 has a _64 variant
        - sparc64 directly include a few files where sparc32 builds them,
          refer to these files directly (no BITS)
        - sneaked in -Werror as used by sparc64
      o modified sparc/Makefile to use the new names for head/init_task

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
