      [SPARC64]: First cut at VIS simulator for Niagara. · 0c51ed93
      David S. Miller 提交于
      Niagara does not implement some of the VIS instructions in
      hardware, so we have to emulate them.

      [SPARC64]: More SUN4V PCI controller work. · bade5622
      David S. Miller 提交于
      Add assembler file for PCI hypervisor calls.
      Setup basic skeleton of SUN4V PCI controller driver.
      
      Add 32-bit devhandle to PBM struct, as this is needed for
      hypervisor calls.

      [SPARC64]: Beginnings of SUN4V PCI controller support. · 8f6a93a1
      David S. Miller 提交于
      Abstract out IOMMU operations so that we can have a different
      set of calls on sun4v, which needs to do things through
      hypervisor calls.

      [SPARC64]: Move away from virtual page tables, part 1. · 74bf4312
      David S. Miller 提交于
      We now use the TSB hardware assist features of the UltraSPARC
      MMUs.
      
      SMP is currently knowingly broken, we need to find another place
      to store the per-cpu base pointers.  We hid them away in the TSB
      base register, and that obviously will not work any more :-)
      
      Another known broken case is non-8KB base page size.
      
      Also noticed that flush_tlb_all() is not referenced anywhere, only
      the internal __flush_tlb_all() (local cpu only) is used by the
      sparc64 port, so we can get rid of flush_tlb_all().
      
      The kernel gets it's own 8KB TSB (swapper_tsb) and each address space
      gets it's own private 8K TSB.  Later we can add code to dynamically
      increase the size of per-process TSB as the RSS grows.  An 8KB TSB is
      good enough for up to about a 4MB RSS, after which the TSB starts to
      incur many capacity and conflict misses.
      
      We even accumulate OBP translations into the kernel TSB.
      
      Another area for refinement is large page size support.  We could use
      a secondary address space TSB to handle those.

      [PATCH] sanitize building of fs/compat_ioctl.c · e6a6d2ef
      Christoph Hellwig 提交于
      Now that all these entries in the arch ioctl32.c files are gone [1], we can
      build fs/compat_ioctl.c as a normal object and kill tons of cruft.  We need a
      special do_ioctl32_pointer handler for s390 so the compat_ptr call is done.
      This is not needed but harmless on all other architectures.  Also remove some
      superflous includes in fs/compat_ioctl.c
      
      Tested on ppc64.
      
      [1] parisc still had it's PPP handler left, which is not fully correct
          for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd
          kick in for all netdevice users.  We can introduce a proper handler
          in one of the next patch series by adding a compat_ioctl method to
          struct net_device but for now let's just kill it - parisc doesn't
          compile in mainline anyway and I don't want this to block this
          patchset.

      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!
