      asm-generic: add MMU variants of io.h functions · f1ecc698
      Jonas Bonn authored
      Some of the implementations, in particular the ioremap variants, in
      asm-generic/io.h are for systems without an MMU.  In order to be able to
      use the generic header file for systems with an MMU, this patch wraps
      these implementations in checks for CONFIG_MMU.
      
      Tested on OpenRISC.

      asm-generic: move archictures to common delay.h · a4e05276
      Jonas Bonn authored
      This patch moves the in-tree architectures that were using the 'generic'
      delay.h over to using the header file in asm-generic.
      
      This is not done using the generic-y mechanism as none of these arch's
      have started using that mechanism yet.  This is a trivial change to make
      later when the arch begins using generic-y.
      
      Note the subtle change to the avr32 and SH architectures where the argument
      to __const_udelay was previously using the rounded down constant value
      instead of the rounded up value.

      asm-generic: delay.h fix udelay and ndelay for 8 bit args · a87e553f
      Andrew Morton authored
      With a non-constant 8-bit argument, a call to udelay() generates a warning:
      
      drivers/gpu/drm/radeon/atom.c: In function 'atom_op_delay':
      drivers/gpu/drm/radeon/atom.c:654: warning: comparison is always false due to limited range of data type
      
      The code looks like it works OK with an 8-bit arg, and the calling code is
      doing nothing wrong, so udelay() needs fixing.
      
      Fixing it was rather tricky.  Simply typecasting `n' in the comparison with
      20000 didn't change anything.  Hence the divide-by-20000 trick.
      
      Using a do{}while loop didn't work because udelay() is used in ?: statements,
      hence the ({...}) construct.
      
      While I was there I replaced the brain-bending ?:?:?: mess with nice if/else
      code.
      
      Probably other architectures are generating the same warning and can use a
      similar change.

      asm-generic: adapt delay.h to common implementation · 30ab2b03
      Jonas Bonn authored
      Several architectures are using a common delay.h implementation that
      appears to have originated with the x86 architecture.  This common
      implementation is a bit fuller than the current asm-generic version
      and has some compile-time checks that should be interesting for all
      architectures.
      
      This patch takes the common delay.h version and replaces the rather
      trivial asm-generic version with it.  As no architecture was actually
      using asm-generic/delay.h, this change is rather innocuous; it will,
      however, allow us to switch at least four architectures over to using
      the asm-generic version.

      Fix node_start/end_pfn() definition for mm/page_cgroup.c · c6830c22
      KAMEZAWA Hiroyuki authored
      commit 21a3c964 uses node_start/end_pfn(nid) for detection start/end
      of nodes. But, it's not defined in linux/mmzone.h but defined in
      /arch/???/include/mmzone.h which is included only under
      CONFIG_NEED_MULTIPLE_NODES=y.
      
      Then, we see
        mm/page_cgroup.c: In function 'page_cgroup_init':
        mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn'
        mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn'
      
      So, fixiing page_cgroup.c is an idea...
      
      But node_start_pfn()/node_end_pfn() is a very generic macro and
      should be implemented in the same manner for all archs.
      (m32r has different implementation...)
      
      This patch removes definitions of node_start/end_pfn() in each archs
      and defines a unified one in linux/mmzone.h. It's not under
      CONFIG_NEED_MULTIPLE_NODES, now.
      
      A result of macro expansion is here (mm/page_cgroup.c)
      
      for !NUMA
       start_pfn = ((&contig_page_data)->node_start_pfn);
        end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});
      
      for NUMA (x86-64)
        start_pfn = ((node_data[nid])->node_start_pfn);
        end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});
      
      Changelog:
       - fixed to avoid using "nid" twice in node_end_pfn() macro.

      btrfs: fix inconsonant inode information · 2f7e33d4
      Miao Xie authored
      When iputting the inode, We may leave the delayed nodes if they have some
      delayed items that have not been dealt with. So when the inode is read again,
      we must look up the relative delayed node, and use the information in it to
      initialize the inode. Or we will get inconsonant inode information, it may
      cause that the same directory index number is allocated again, and hit the
      following oops:
