      [PATCH] Support AGP bridge on Nvidia Nforce3 + cleanup · a33161f5
      Andi Kleen authored
      For some unknown reasons Nvidia NForce3 doesn't use the standard Hammer AGP architecture,
      but requires set up of some shadow registers. This patch adds that to the K8 AGP driver.
      
      Based on an old 2.4 patch from someone at Nvidia.
      
      Also includes another bug fix for the K8 AGP handler, from Brad House.
      We should not assume that there is only one northbridge in a Uniprocessor system.
      Always flush all.
      
      Also some minor cleanup.

      [PATCH] Run 32bit compat ioctl handlers in BKL · f9d3880b
      Andi Kleen authored
      Give 32bit emulation ioctl handlers the same locking rules as normal ioctl handlers.
      This will avoid surprises in driver code.
      
      Most call sys_ioctl who would take it anyways.

      [PATCH] New machine check handler for x86-64 · 047379fb
      Andi Kleen authored
      This adds a new completely rewritten machine check handler for x86-64.
      The old one never worked on 2.6.
      
      The new handler has many improvements. It closely follows the Intel and AMD
      recommendations on MCE handlers now (the old one had many violations). It handles
      unrecoverable errors in user space better now - it will only kill the process now
      if possible instead of panicing.
      
      This one is CPU independent now - it should work on any CPU that supports the standard
      x86 MCA architecture.
      
      This new handler only logs fatal errors that lead to kernel panic to the console.
      Non fatal errors are logged race free into a new (non ring) buffer now
      and supplied to the user using a new character device.  The old one could
      deadlock on console and printk locks. This also separates machine check errors
      from real kernel errors better. The new buffer has been also designed to
      be easily accessible from external debugging tools: it has a signature
      and could be even recovered after reboot. It is not organized as a ring buffer -
      this means the first errors are kept unless explicitely cleared.
      
      The new error formats can be parsed using ftp://ftp.suse.com/pub/people/ak/x86-64/mcelog.c
      The new character device for it can be created with mknod /dev/mcelog c 10 227
      
      There is a new sysfs interface to configure the machine check handler.
      It has a "tolerant" parameter that defines the aggressiveness of the machine check:
      
      0: always panic
      1: panic if deadlock possible (e.g. MCE happened in the kernel)
      2: try to avoid panic
      
      Default is 2
      
      Despite of having more features the new handler is shorter.

      [PATCH] x86-64 merge for 2.6.3 · 386eaf87
      Andi Kleen authored
      Bring the x86-64 port up to date. Lots of smaller bug fixes that have accumulated.
      Also fixes another nasty bug introduced by the IA32e changes that causes BUGs at
      boot for some people.
      
      Only changes x86-64 specific files. There are some other changes that I'm sending
      separately.
      
       - Some cleanup in NMI watchdog code
       - Fix HyperThreading CPU setup race (Suresh B. Siddha)
       - Update defconfig
       - Add a comment on why iommu_fullflush is disabled.
       - Export sys_ioctl again
       - Fix build with IA32_EMULATION=y and SYSVIPC=n
       - Remove noisy boot printks in the mptable scan.
       - Implement automatic NMI watchdog switching for real now
       - Remove redundant 32bit ioctl handlers for autofs
       - Remove CONFIG ifdefs around rtc 32bit ioctl handlers
       - Remove useless nfsctl ifdef in syscall.c (Al Viro)
       - Increase padding for prefetchw alternative
       - Check for NX bit early before setting up memory maps (Suresh B. Siddha)
       - Change Intel IA32e config description and fix help texts (Jun Nakajima)
       - Fix microcode driver build really now (Dave Jones)
       - Add nohpet option to disable HPET timer
       - Fix double semicolon in aperture.c
       - Add cmpxchg16b cpuid entry
       - Fix return value of read_pci_config_16 (Paul Menage)
       - Fix __KERNEL_COMPAT32_CS (Zachary Amsden)
       - Disable the infamous 30 minutes check in CMOS time setting
       - Update URLs in Kconfig (Petri T. Koistinen)
       - Fix ACPI interrupt source parsing for Nforce3 (Maciej W. Rozycki)
       - Fix 32bit ipc version parsing.
       - Run local APIC NMI watchdog only once a second (or less often on idle boxes)
       - Merge ACPI APIC SCI functions from i386
       - Add i8254 timer suspend code from i386
       - Merge with 2.6.2-rc3 + minor changes from i386
       - Fix empty_zero_page declaration (Greg Johnson)
       - Readd sysctls for exception/page fault trace and vsyscall32
       - Fix WCHAN
       - Fix STACK_TOP usage. Stack for 64bit processes should be at the
         top of memory now again. Also set it correctly for LINUX32_3GB.
       - Add warning fixes for gcc 3.4 and -Wdeclaration-after-statement

      [PATCH] asmlinkage fixes · 4c238c91
      Andrew Morton authored
      From: Andreas Gruenbacher <agruen@suse.de>,
            and me.
      
      Latest gcc cvs is able to detect mismatches between functions which are
      tagged asmlinkage and declarations which are missing asmlinkage.  Or vice
      versa.
      
      Fix up the fallout from an x86 allyesconfig build.

      [PATCH] add syscalls.h · 0bab0642
      Andrew Morton authored
      From: "Randy.Dunlap" <rddunlap@osdl.org>
      
      Add syscalls.h, which contains prototypes for the kernel's system calls.
      Replace open-coded declarations all over the place.  This patch found a
      couple of prior bugs.  It appears to be more important with -mregparm=3 as we
      discover more asmlinkage mismatches.
      
      Some syscalls have arch-dependent arguments, so their prototypes are in the
      arch-specific unistd.h.  Maybe it should have been asm/syscalls.h, but there
      were already arch-specific syscall prototypes in asm/unistd.h...
      
      Tested on x86, ia64, x86_64, ppc64, s390 and sparc64.  May cause
      trivial-to-fix build breakage on other architectures.
