      kvm: exclude ioeventfd from counting kvm_io_range limit · 6ea34c9b
      Amos Kong authored
      We can easily reach the 1000 limit by start VM with a couple
      hundred I/O devices (multifunction=on). The hardcode limit
      already been adjusted 3 times (6 ~ 200 ~ 300 ~ 1000).
      
      In userspace, we already have maximum file descriptor to
      limit ioeventfd count. But kvm_io_bus devices also are used
      for pit, pic, ioapic, coalesced_mmio. They couldn't be limited
      by maximum file descriptor.
      
      Currently only ioeventfds take too much kvm_io_bus devices,
      so just exclude it from counting kvm_io_range limit.
      
      Also fixed one indent issue in kvm_host.h

      KVM: get rid of $(addprefix ../../../virt/kvm/, ...) in Makefiles · 535cf7b3
      Marc Zyngier authored
      As requested by the KVM maintainers, remove the addprefix used to
      refer to the main KVM code from the arch code, and replace it with
      a KVM variable that does the same thing.

      ARM: KVM: move GIC/timer code to a common location · 7275acdf
      Marc Zyngier authored
      As KVM/arm64 is looming on the horizon, it makes sense to move some
      of the common code to a single location in order to reduce duplication.
      
      The code could live anywhere. Actually, most of KVM is already built
      with a bunch of ugly ../../.. hacks in the various Makefiles, so we're
      not exactly talking about style here. But maybe it is time to start
      moving into a less ugly direction.
      
      The include files must be in a "public" location, as they are accessed
      from non-KVM files (arch/arm/kernel/asm-offsets.c).
      
      For this purpose, introduce two new locations:
      - virt/kvm/arm/ : x86 and ia64 already share the ioapic code in
        virt/kvm, so this could be seen as a (very ugly) precedent.
      - include/kvm/  : there is already an include/xen, and while the
        intent is slightly different, this seems as good a location as
        any
      
      Eventually, we should probably have independant Makefiles at every
      levels (just like everywhere else in the kernel), but this is just
      the first step.

      Pull tracing/kprobes update from Steven Rostedt:
       "The majority of these changes are from Masami Hiramatsu bringing
        kprobes up to par with the latest changes to ftrace (multi buffering
        and the new function probes).
      
        He also discovered and fixed some bugs in doing so.  When pulling in
        his patches, I also found a few minor bugs as well and fixed them.
      
        This also includes a compile fix for some archs that select the ring
        buffer but not tracing.
      
        I based this off of the last patch you took from me that fixed the
        merge conflict error, as that was the commit that had all the changes
        I needed for this set of changes."
