      gcov: enable GCOV_PROFILE_ALL for x86_64 · 7bf99fb6
      Peter Oberparleiter 提交于
      Enable gcov profiling of the entire kernel on x86_64. Required changes
      include disabling profiling for:
      
      * arch/kernel/acpi/realmode and arch/kernel/boot/compressed:
        not linked to main kernel
      * arch/vdso, arch/kernel/vsyscall_64 and arch/kernel/hpet:
        profiling causes segfaults during boot (incompatible context)

      x86: unify arch/x86/boot/compressed/vmlinux_*.lds · 51b26ada
      Linus Torvalds 提交于
      Look at the:
      
      	diff -u arch/x86/boot/compressed/vmlinux_*.lds
      
      output and realize that they're basially exactly the same except for
      trivial naming differences, and the fact that the 64-bit version has a
      "pgtable" thing.
      
      So unify them.
      
      There's some trivial cleanup there (make the output format a Kconfig thing
      rather than doing #ifdef's for it, and unify both 32-bit and 64-bit BSS
      end to "_ebss", where 32-bit used to use the traditional "_end"), but
      other than that it's really very mindless and straigt conversion.
      
      For example, I think we should aim to remove "startup_32" vs "startup_64",
      and just call it "startup", and get rid of one more difference. I didn't
      do that.
      
      Also, notice the comment in the unified vmlinux.lds.S talks about
      "head_64" and "startup_32" which is an odd and incorrect mix, but that was
      actually what the old 64-bit only lds file had, so the confusion isn't
      new, and now that mixing is arguably more accurate thanks to the
      vmlinux.lds.S file being shared between the two cases ;)

      bzip2/lzma: x86 kernel compression support · ae03c499
      Alain Knaff 提交于
      Impact: Replaces x86 kernel decompressor with new code
      
      This is the third part of the bzip2/lzma patch
      
      The bzip patch is based on an idea by Christian Ludwig, includes support for
      compressing the kernel with bzip2 or lzma rather than gzip. Both
      compressors give smaller sizes than gzip.  Lzma's decompresses faster
      than bzip2.
      
      It also supports ramdisks and initramfs' compressed using these two
      compressors.
      
      The functionality has been successfully used for a couple of years by
      the udpcast project
      
      This version applies to "tip" kernel 2.6.28
      
      This part contains:
      - support for new bzip2 and lzma kernel compression for x86

      x86: boot/compressed/Makefile: fix "make clean" · 7f16a339
      H. Peter Anvin 提交于
      The Kbuild variable "targets" is supposed to be
      configuration-independent and reflect "all possible targets".  This is
      required to make "make clean" work properly.
      
      Therefore, move all manipulation of "targets" as well as custom rules
      out of the x86-32 ifdef statement.  Only leave inside the ifdefs the
      things that are genuinely configuration-dependent.

      [PATCH] i386: Warn upon absolute relocations being present · 6a044b3a
      Vivek Goyal 提交于
      o Relocations generated w.r.t absolute symbols are not processed as by
        definition, absolute symbols are not to be relocated. Explicitly warn
        user about absolutions relocations present at compile time.
      
      o These relocations get introduced either due to linker optimizations or
        some programming oversights.
      
      o Also create a list of symbols which have been audited to be safe and
        don't emit warnings for these.

      [PATCH] i386: Relocatable kernel support · 968de4f0
      Eric W. Biederman 提交于
      This patch modifies the i386 kernel so that if CONFIG_RELOCATABLE is
      selected it will be able to be loaded at any 4K aligned address below
      1G.  The technique used is to compile the decompressor with -fPIC and
      modify it so the decompressor is fully relocatable.  For the main
      kernel relocations are generated.  Resulting in a kernel that is relocatable
      with no runtime overhead and no need to modify the source code.
      
      A reserved 32bit word in the parameters has been assigned
      to serve as a stack so we figure out where are running.

      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!
