      [PATCH] x86-64 updates for 2.5.43 · 3428c8d1
      Andi Kleen authored
      This fixes a few files that got lost with the last merge and merges
      with 2.5.43/i386.  Only changes architecture specific files.
      
      It depends on one other patch (for linux/ioctl32.h) which I'm sending
      separately.
      
      Changes:
      - Include missing files (pageattr.c) and Makefile changes
      - Update IA32 subsystem. Various small fixes and a big merge
        with sparc64.
      - Change HZ to 1000
      - Merge some of the 2.5.43/i386 profiling changes. No full oprofile yet.
      - Fix many warnings
      - Update defconfig
      - Various other smaller cleanups and bugfixes.

      [PATCH] x86-64 IA32 emulation updates · 0e97e2a2
      Andi Kleen authored
      Some bugfixes for the 32bit emulation for x86-64 and make it all compile
      again.
      
      Has rewritten ioctl registration code and some other updates.  New
      system calls are supported.
      
      It unfortunately broke some time ago by binfmt_elf changes for all
      shared linked libraries.  Will fix that later.

      [PATCH] 2.5.21 x86-64 jumbo patch - arch specific changes · e4b9e2aa
      Andi Kleen authored
      Here is the big 2.5.21 x86-64 sync patch. It only touches arch/x86_64
      and include/asm-x86_64. It requires a few other changes that I'm sending
      in separate mail.
      
      Changes:
      - merge wit 2.5.21
      - merge from 2.5.21/i386 (new PCI code, new LDT code etc.)
      - sync with 2.4-x86_64 tree.
      - minor updates to 32bit emulation
      - better early console; including serial support.
      - now set up dummy PDA for booting to avoid problems
      - Fix GS reloading in context switch one instruction race
      - Remove hardcoded names from mpparse code
      - Fix inline assembly for RAID-5 xor (similar change needed for i386)
      - Real per cpu data support based on PDA field
      - Cleanup of offset.c generation requested by Kai: it only puts structure
        offsets into offset.h now.
      - Fix i387 fxsave signal frame problems.
      - Add uname emulation via personality ("linux32")
      - New SSE optimized checksum-copy, copy*user, memcpy, clear_page, copy_page
        functions. Other tunings/cleanups in checksum and other user memory
        access function.
      - check if exception table is really sorted
      - Cleanups in page table handling in preparation of non executable pages
        support.
      - Cleanup PDA access to not require offset.h (thanks to kai for kicking me
        to this)
      - use long long for u64/s64 to avoid more warnings
      - remove CONFIG_ISA
      - fix various bugs and other cleanups

      [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
