      [PATCH] x86-64 architecture specific sync for 2.5.8 · 88e4bc32
      Andi Kleen authored
      This patch brings 2.5.8 in sync with the x86-64 2.4 development tree again
      (excluding device drivers)
      
      It has lots of bug fixes and enhancements. It only touches architecture
      specific files.
      
      - Sync with 2.5.8
      - SMP/APIC supported now.
      - Module loading works now.
      - Time keeping bugs fixed.
      - entry.S streamlined and some bugs fixed.
      - modify_ldt works now
      - mostly rewritten FPU support (including FXRSTOR for initial FPU
        initialization based on the initial state)
      - 32bit emulation enhanced and bugs fixed.
      - rewrote mm initialization and lots of cleanups in the page table handling
        __PAGE_OFFSET is now moved to 0x10000000000 and some vmalloc/ioremap
        problems have been fixed. They have an own PML4 slot now.
      - WCHAN reporting support for RIP (but not RSP)
      - Lots of various other bug fixes and cleanups.
      
      Currently broken:
      - ACPI
      - MTRR
      
      It needs some other bugfixes outside architecture specific code. I sent
      them all in separate mail.

      [PATCH] x86_64 merge: arch + asm · 0457d99a
      Andi Kleen authored
      This adds the x86_64 arch and asm directories and a Documentation/x86_64.
      
      It took a bit longer because I first had to make preemption and thread_info
      work and also found some other bugs while doing this. The port has been
      tested for a long time on UP.
      
      I'm not sure what I should describe.  A lot is based on i386 with
      a lot of cleanups. I wrote a paper about it for last year's OLS that describes
      most of the changes (ftp://ftp.firstfloor.org/pub/ak/x86_64.ps.gz). It is
      a bit outdated now, but should give a good overview.
      
      It currently has a completely cut'n'pasted from others+hacked 32bit
      emulation. I hope to clean that up in the future by merging the generic
      core of this with other 64bit archs.
      
      Thanks,
      -Andi
