      [PATCH] remove check_region from drivers_isdn_hisax_w6692.c · 22084c7e
      William Stinson authored
        This patch for driver drivers/isdn/hisax/bkm_a8.c for Linux removes
        one call to check_region using request_region instead.
      
        I don't have this hardware so I hope I got it right.  This patch
        removes all references to check_region in this driver.
      
        This is patch number 23 in a series of check_region patches I am doing as

      [PATCH] ip27-rtc.c create_proc_read_entry patch · 73ef1072
      Chris Wilson authored
        As part of my work on the Linux Kernel Janitors project, cleaning up on
        functions which call create_proc_*_entry and don't check for an error
        return, I would like to submit my patch to arch/mips64/sgi-ip27/ip27-rtc.c.
      
        This patch adds a printk() if misc_register fails (since that causes the
        driver to fail to load, it should be logged somewhere), and checks that
        create_proc_read_entry returned a valid handle. ENOENT seems to me like a
        good error code to return in this case, although EBUSY is a candidate too.

      [PATCH] Kernel Janitors patch to drivers_macintosh_ans-lcd.c · 5c6e6c72
      Chris Wilson authored
        Working on the Linux Kernel Janitors project, and following up on Mikal
        Still's work there, I'd like to submit a patch for the Macintosh ANS
        LCD driver.
      
        I believe from Mikal's Patches page that his previous patch was rejected
        due to not cleaning up properly. I believe my patch addresses this issue,
        by calling iounmap() to free the IO remapping created by ioremap() earlier
        in the function, if the call to misc_register() fails for any reason.
      
        Unfortunately I don't know how to get this driver to compile on my
        machine, and therefore I can't even check that my patch compiles. If you
        can advise me how to set my machine up to dompile these drivers, then
        please get in touch =) I hope I didn't make any stupid mistakes in this
        patch either.

      [PATCH] Fix errors making Docbook documentation · ff346687
      Craig Wilkie authored
        This modifies the following files: -
      
        Documentation/Docbook/Makefile - Fix dependencies generating parportbook
        which caused tex to choke.
      
        Documentation/Docbook/kernel-api.tmpl - Remove references to source

        and clean up Documentation/DocBook to kill all the warnings that occur
        during "make pdfdocs" and generally make the documents look nicer, and

       Old format: modname modsize [refcount [dep1] [dep2] ...]
      
       New format: modname modsize refcount deps1,[dep2,]...
      
      The module-init-tools have understood this format for over a month now.
      This change allows us to add new fields, ie.  module state, module
      address, etc.

      [PATCH] Exception table cleanup · af285fc8
      Rusty Russell authored
      This patch combines the common exception table searching functionality
      for various architectures, to avoid unneccessary (and currently buggy)
      duplication, and so that the exception table list and lock can be kept
      private to module.c.
      
      The archs provide "struct exception_table" and "search_extable": the
      generic infrastructure drives the rest.

      [PATCH] Dynamically size the pidhash hash table. · 9a7dad1c
      Andrew Morton authored
      Patch from Bill Irwin.   Prodding from me.
      
      The hashtables in kernel/pid.c are 128 kbytes, which is far too large for
      very small machines.
      
      So we dynamically size them and allocate them from bootmem.  From 16 buckets
      on the very smallest machine up to 4096 buckets (effectively half the current
      size) with one gigabyte of memory or more.
      
      The patch also switches the hashing from a custom hash over to the more
      powerful hash_long().

      [PATCH] shrink the amount of vmalloc space reserved for kmap · 148b113a
      Andrew Morton authored
      Patch from Manfred Spraul <manfred@colorfullife.com>
      
      Effectively adds another 24 megabytes of ia32 KVA.
      
      kmap uses a 4 MB (2 MB if PAE is enabled) area for the persistant mappings.
      But PKMAP_BASE is 4GB-32MB, i.e.  around 28 MB are reserved for kmap (4 MB
      for fixmappings).
      
      The attached patch shrink that to 4 MB (+4MB for fixmappings) and adds a test
      to check for an overlap between fixmap and kmap areas.

      [PATCH] handle radix_tree_node allocation failures · c3ed96a7
      Andrew Morton authored
      This patch uses the radix_tree_preload() API in add_to_page_cache().
      
      A new gfp_mask argument is added to add_to_page_cache(), which is then passed
      on to radix_tree_preload().   It's pretty simple.
      
      In the case of adding pages to swapcache we're still using GFP_ATOMIC, so
      these addition attempts can still fail.  That's OK, because the error is
      handled and, unlike file pages, it will not cause user applicaton failures.
      This codepath (radix-tree node exhaustion on swapout) was well tested in the
      days when the swapper_space radix tree was fragmented all over the place due
      to unfortunate swp_entry bit layout.

      [PATCH] infrastructure for handling radix_tree_node allocation · 9fb6fde9
      Andrew Morton authored
      radix_tree_node_alloc() uses GFP_ATOMIC, under spinlocking.  If the
      allocation fails then userspace sees ENOMEM and application failure occurs.
      
      A single add_to_page_cache() will require up to six radix_tree_nodes on
      32-bit machines, twice this on 64-bit machines (quadruple the worst-case
      storage on 64-bit).
      
      My approach to solving this problem is to create a per-cpu pool of
      preallocated radix_tree_nodes, private to the radix-tree code.
      
      The radix-tree user will call the new radix-tree API function
      radix_tree_preload() to ensure that this pool has sufficient nodes to cover
      the worst-case.  radix_tree_preload() should be called outside locks, with
      GFP_KERNEL so that it can run page reclaim.
      
      If it succeeds, radix_tree_preload() will return with preemption disabled so
      that the per-cpu radix_tree_node pool is protected.  The user must call
      radix_tree_preload_end() to terminate the transaction.
      
      In the common case, the per-cpu pools will never be touched:
      radix_tree_insert() will only dip into the pool if kmem_cache_alloc() fails.
      The pools will remain full at all times.  This is to optimise the fastpath -
      it is just a few instructions.
      
      This patch also removes the now-unneeded radix-tree mempool.  This saves 130
      kbytes of permanently allocated kernel memory.  260k on 64-bit platforms.

      [PATCH] handle pte_chain_alloc() failures · aaf2ef19

      and to pass those into page_add_rmap().

      [PATCH] infrastructure for handling pte_chain_alloc() failures · a3a31a5e
      Andrew Morton authored
      The VM allocates pte_chains with GFP_ATOMIC, under deep locking.  If that
      allocation fails, we oops.
      
      My approach to solving this is to require that the caller of page_add_rmap()
      pass in a pte_chain structure for page_add_rmap() to use.  Then, callers can
      arrange to allocate that structure outside locks with GFP_KERNEL.
      
      This patch provides the base infrastructure.
      
      A common case is that page_add_rmap() will in fact not consume the pte_chain,
      because an empty slot was found within one of the page's existing pte_chain
      structures.  So this patch provides for a special one-deep per-cpu pte_chain
      cache to optimise this case of taking just one pte_chain and then immediately
      putting it back.
      
      We end up adding maybe 20-30 instructions to the pagefault path to handle the
      eventuality of pte_chain allocation failures.
      
      Lots of other design ideas were considered.  This is the best I could come up
      with.

                 Milton Miller <miltonm@bga.com>
      
      There's some init-time code which is supposed to read a devfs directory by

      and it only works if the whole directory fits into 512 bytes.
      
      So fix that up, and also clean up some coding in there, and rationalise the
      duplicated definition of linux_dirent64.
