      x86: trivial printk optimizations · 9b706aee
      Denys Vlasenko 提交于
      In arch/x86/boot/printf.c gets rid of unused tail of digits: const char
      *digits = "0123456789abcdefghijklmnopqrstuvwxyz"; (we are using 0-9a-f
      only)
      
      Uses smaller/faster lowercasing (by ORing with 0x20)
      if we know that we work on numbers/digits. Makes
      strtoul smaller, and also we are getting rid of
      
        static const char small_digits[] = "0123456789abcdefx";
        static const char large_digits[] = "0123456789ABCDEFX";
      
      since this works equally well:
      
        static const char digits[16] = "0123456789ABCDEF";
      
      Size savings:
      
      $ size vmlinux.org vmlinux
         text    data     bss     dec     hex filename
       877320  112252   90112 1079684  107984 vmlinux.org
       877048  112252   90112 1079412  107874 vmlinux
      
      It may be also a tiny bit faster because code has less
      branches now, but I doubt it is measurable.

      [PATCH] ppc64: make arch/ppc64/boot standalone · decd300b
      Olaf Hering 提交于
      Make the bootheader for ppc64 independent from kernel and libc headers.
      * add -nostdinc -isystem $gccincludes to not include libc headers
      * declare all functions in header files, also the stuff from string.S
      * declare some functions static
      * use stddef.h to get size_t (hopefully ok)
      * remove ppc32-types.h, only elf.h used the __NN types
      
      With further modifications by Paul Mackerras and Stephen Rothwell.

      Linux-2.6.12-rc2 · 1da177e4

      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!
