      sh: trapped io support V2 · e7cc9a73
      Magnus Damm 提交于
      The idea is that we want to get rid of the in/out/readb/writeb callbacks from
      the machvec and replace that with simple inline read and write operations to
      memory. Fast and simple for most hardware devices (think pci).
      
      Some devices require special treatment though - like 16-bit only CF devices -
      so we need to have some method to hook in callbacks.
      
      This patch makes it possible to add a per-device trap generating filter. This
      way we can get maximum performance of sane hardware - which doesn't need this
      filter - and crappy hardware works but gets punished by a performance hit.
      
      V2 changes things around a bit and replaces io access callbacks with a
      simple minimum_bus_width value. In the future we can add stride as well.

      increase AT_VECTOR_SIZE to terminate saved_auxv properly · 4f9a58d7
      Olaf Hering 提交于
      include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO.  fs/binfmt_elf.c
      has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT
      entries.  So in the worst case, saved_auxv does not get an AT_NULL entry at
      the end.
      
      The saved_auxv array must be terminated with an AT_NULL entry.  Make the
      size of mm_struct->saved_auxv arch dependend, based on the number of
      ARCH_DLINFO entries.

      sh: Fixup __cmpxchg() compile breakage with gcc4. · 310f7963
      Paul Mundt 提交于
      As reported by Manuel:
      
      When I build linux with GCC-4.x and enable
      CONFIG_CC_OPTIMIZE_FOR_SIZE linking fails with this error:
      
        LD      .tmp_vmlinux1
        kernel/built-in.o: In function '__cmpxchg_called_with_bad_pointer'
        make[1]: *** [.tmp_vmlinux1] Error 1
        make: *** [_all] Error 2
      
      This ended up being an inlining problem, fixed by explicitly
      including linux/compiler.h and grabbing the definitions from there.

      sh: Fix exception_handling_table alignment. · 1f666587
      Paul Mundt 提交于
      With the recent change ripping out interrupt_table, explicit
      padding of the table was missing, causing bad things to happen
      when manually inserting handlers in to the table. This problem
      particularly showed up in relation to do_fpu_state_restore()
      which was inserted quite deeply in to the table and ended up
      scribbling over a slab object.

      [PATCH] remove set_wmb - arch removal · 52393ccc
      Steven Rostedt 提交于
      set_wmb should not be used in the kernel because it just confuses the
      code more and has no benefit.  Since it is not currently used in the
      kernel this patch removes it so that new code does not include it.
      
      All archs define set_wmb(var, value) to do { var = value; wmb(); }
      while(0) except ia64 and sparc which use a mb() instead.  But this is
      still moot since it is not used anyway.
      
      Hasn't been tested on any archs but x86 and x86_64 (and only compiled
      tested)

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      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!
