      [PATCH] slob: introduce the SLOB allocator · 10cef602
      Matt Mackall 提交于
      configurable replacement for slab allocator
      
      This adds a CONFIG_SLAB option under CONFIG_EMBEDDED.  When CONFIG_SLAB is
      disabled, the kernel falls back to using the 'SLOB' allocator.
      
      SLOB is a traditional K&R/UNIX allocator with a SLAB emulation layer,
      similar to the original Linux kmalloc allocator that SLAB replaced.  It's
      signicantly smaller code and is more memory efficient.  But like all
      similar allocators, it scales poorly and suffers from fragmentation more
      than SLAB, so it's only appropriate for small systems.
      
      It's been tested extensively in the Linux-tiny tree.  I've also
      stress-tested it with make -j 8 compiles on a 3G SMP+PREEMPT box (not
      recommended).
      
      Here's a comparison for otherwise identical builds, showing SLOB saving
      nearly half a megabyte of RAM:
      
      $ size vmlinux*

      $ size mm/{slab,slob}.o
         text    data     bss     dec     hex filename
        13221     752      48   14021    36c5 mm/slab.o

      powerpc: Merge enough to start building in arch/powerpc. · 14cf11af
      Paul Mackerras 提交于
      This creates the directory structure under arch/powerpc and a bunch
      of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
      arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
      to build a 32-bit powermac kernel with ARCH=powerpc.
      
      For now we are getting some unmerged files from arch/ppc/kernel and
      arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
      to files in those directories and files outside arch/powerpc.
      
      The boot directory is still not merged.  That's going to be interesting.

      [PATCH] kdump: Access dump file in elf format (/proc/vmcore) · 666bfddb
      Vivek Goyal 提交于
      From: "Vivek Goyal" <vgoyal@in.ibm.com>
      
      o Support for /proc/vmcore interface. This interface exports elf core image
        either in ELF32 or ELF64 format, depending on the format in which elf headers
        have been stored by crashed kernel.
      o Added support for CONFIG_VMCORE config option.
      o Removed the dependency on /proc/kcore.
      
      From: "Eric W. Biederman" <ebiederm@xmission.com>
      
      This patch has been refactored to more closely match the prevailing style in
      the affected files.  And to clearly indicate the dependency between
      /proc/kcore and proc/vmcore.c
      
      From: Hariprasad Nellitheertha <hari@in.ibm.com>
      
      This patch contains the code that provides an ELF format interface to the
      previous kernel's memory post kexec reboot.

      [PATCH] meminfo: add Cached underflow check · 4c4c402d
      Martin Hicks 提交于
      Working on some code lately I've been getting huge values for "Cached".
      The cause is that get_page_cache_size() is an approximate value, and for a
      sufficiently small returned value of get_page_cache_size() the value
      underflows.

      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!
