• 4481374ce   mm: replace various uses of num_physpages by totalram_pages ... Browse Code »

  Sizing of memory allocations shouldn't depend on the number of physical
  pages found in a system, as that generally includes (perhaps a huge amount
  of) non-RAM pages. The amount of what actually is usable as storage
  should instead be used as a basis here.

  Some of the calculations (i.e. those not intending to use high memory)
  should likely even use (totalram_pages - totalhigh_pages).

• 9e2779fa2   is_vmalloc_addr(): Check if an address is within the vmalloc boundaries ... Browse Code »

  Checking if an address is a vmalloc address is done in a couple of places.
  Define a common version in mm.h and replace the other checks.

  Again the include structures suck. The definition of VMALLOC_START and
  VMALLOC_END is not available in vmalloc.h since highmem.c cannot be included
  there.

  pages and this ensures we play nice with the VM and the system as a
  whole.

• dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

  - added typedef unsigned int __nocast gfp_t;

  - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
  the same warnings as far as sparse is concerned, doesn't change
  generated code (from gcc point of view we replaced unsigned int with
  typedef) and documents what's going on far better.

• 06d0e3cf3   NTFS: Allow highmem kmalloc() in ntfs_malloc_nofs() and add _nofail() version. ... Browse Code »

  - Modify fs/ntfs/malloc.h::ntfs_malloc_nofs() to do the kmalloc() based
  allocations with __GFP_HIGHMEM, analogous to how the vmalloc() based
  allocations are done.
  - Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
  ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
  hence cannot fail.

• 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

  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!
