catching up on the backlog

From: <tony.luck_at_intel.com>
Date: 2005-05-04 07:08:58
I've picked through the list of patches in my backlog, and applied
this bunch to my release tree ... before I ask Linus to pull, it
would be useful to get some SGI testing (since the majority of the
changes are SGI related).

    [patch] MCA recovery module undefined symbol fix

    The patch "MCA recovery improvements" added do_exit to mca_drv.c.
    That's fine when the mca recovery code is built in the kernel
    (CONFIG_IA64_MCA_RECOVERY=y) but breaks building the mca recovery
    code as a module (CONFIG_IA64_MCA_RECOVERY=m).

    Most users are currently building this as a module, as loading
    and unloading the module provides a very convenient way to turn
    on/off error recovery.

    This patch exports do_exit, so mca_drv.c can build as a module.

    [IA64] MCA recovery improvements

    Jack Steiner uncovered some opportunities for improvement in
    the MCA recovery code.

      1) Set bsp to save registers on the kernel stack.
      2) Disable interrupts while in the MCA recovery code.
      3) Change the way the user process is killed, to avoid 
         a panic in schedule.

    Testing shows that these changes make the recovery code much 
    more reliable with the 2.6.12 kernel.

    [IA64] fix ia64 syscall auditing

    Attached is a patch against David's audit.17 kernel that adds checks
    for the TIF_SYSCALL_AUDIT thread flag to the ia64 system call and
    signal handling code paths.  The patch enables auditing of system
    calls set up via fsys_bubble_down, as well as ensuring that
    audit_syscall_exit() is called on return from sigreturn.

    Neglecting to check for TIF_SYSCALL_AUDIT at these points results in
    incorrect information in audit_context, causing frequent system panics
    when system call auditing is enabled on an ia64 system.

    I have tested this patch and have seen no problems with it.

    [IA64] reduce cacheline bouncing in cpu_idle_wait

    Andi noted that during normal runtime cpu_idle_map is bounced around a lot,
    and occassionally at a higher frequency than the timer interrupt wakeup
    which we normally exit pm_idle from.  So switch to a percpu variable.

    I didn't move things to the slow path because it would involve adding
    scheduler code to wakeup the idle thread on the cpus we're waiting for.

    [IA64-SGI] Altix only: Remove hubdev SAL call 

    Hi Tony,

    This patch against ia64-test-2.6.12 fixes a bug where the tiocx code
    was inadvertently un-doing some address modifications done in earlier
    fixup code.    This patch just removes the offending code.

    [IA64] use fc.i for fluch_icache_range()

    This is a small patch to switch fluch_icache_range() to use fc.i
    instead of fc.  This would save time on processors which can establish
    i-cache coherency without flushing the cache-line out to memory (not
    that any current processors do).  On existing processors, fc.i behaves
    like fc.  The only caveat is that very old assemblers may not know
    about fc.i yet.

    [IA64-SGI] cleanup shubio.h

    [IA64-SGI] remove unused sn header files

    This patch makes Jes' patch (which also contains the removal of fetchop.h) a 
    bit smaller, and removes two other unused files at the same time, sndrv.h and 
    sn_fru.h.

    [IA64] fix typos caught by new assembler

    Patch below fixes 3 trivial typos which are caught by the new
    assembler (v2.169.90).  Please apply.

    [Note: fix to memcpy that was also part of this patch was separately
     applied from patches by H.J. and Andreas ... so the delta here only
     has the other two fixes. -Tony]

    [IA64] Add config SCHED_SMT

    Now that we have MC/MT detection patches in, appended patch allows us to
    configure MT scheduler optimizations. For now, we will this option off
    by default.

    There is some discussion going on lkml about setting up sched-domains 
    which are absolutely needed (like for example, we shouldn't setup SMT domain
    for non MT processors). Once that patch goes in, we can enable this option by
    default.
