the handling of loader-created sections.

the attached patch (against bk-current) fixes a cross 
compilation problem by using the target specific objdump 
tool instead of the host specific one.

	ia64_sal_mc_rendez().  Also prefix local-variables in
	SAL macros to avoid name collisions.

We are not setting the 'always rendezvous for mca' flag.  kdb needs it
set to get decent mca debugging on all cpus but I do not want kdb to
change sal behaviour.  Since we do not recover from mca without a
debugger, I see no reason why this flag should not be on for all
kernels.

The rendezvous timeout was set to 100 * HZ, but SAL expects the timeout
to be in milliseconds, HZ may not be 1 millisecond.  The patch makes
the timeout an explicit 20 seconds, semi-arbitrary value.

thoroughly broken ia64 patch).  Not all relocs are supported yet and the reloc
code needs to be cleaned up, but simply stuff like loading the palinfo module
works.  Also, linkage-stubs are optimized with brl for McKinley or better.

Trying to port some patches from i386 to ia64 I've found that
show_trace_task is the only portable way to show tasks' call
traces(perhaps because it is called from ./kernel/sched.c:)).
But its ia64 implementation can't work with running task.

Attached patch fixes this issue.

As I understand show_trace and show_stack are platform
dependent or have different sense/args.

Here's patches for 2.4 & 2.5 to use PAL_HALT_LIGHT in cpu_idle.
This helps to reduce CPU temp a little on boxes with firmware that
takes advantage of this lower power state.  I've tried this on a
rx2600 (2x900MHz McKinley) and an i2000 (fw 117) and it shows some
benefit.  On McKinley systems, only the very latest PAL from Intel
actually reduces power consumption in the halt_light state.  For HP
rx2600/zx6000/zx2000, this means you need to be running firmware 1.82.

  Rohit Seth, at Intel, has run some benchmarks with this kind of
modification and found the effects of enabling halt_light to fall
within the noise of mosts tests.  I replaced pal_halt(1) in safe_halt
with pal_halt_light() since halt_light is required to be implemented,
but pal_halt(1) is an optional halt state.  I'd be interested to hear
of any measurements anyone does using this, where it works/fails, and
if any benchmarks/applications are impacted.

David, here's an updated patch that doesn't mess with
arch/ia64/Makefile in case you hadn't applied the last one yet

Here is a simple patch to also print isr during the handling of a
floating point assist fault.

The consensus on lkml was that devices should do reads from safe
registers to ensure PIO write ordering, which means we no longer need
mmiob.  This patch removes the mmiob entries from the machine vector
headers and io.h and updates the documentation about PIO ordering.

should not use such innocent variable names like tmp because they
have a high probability to clash with (part of) the argument.

The patch allows unw_access_gr() to read from r0, to support unwind
directives such as .save ar.pfs,r0 and .save rp,r0.

Here is a patch to have the POSIX timer interface completly integrated
in ia64 (2.5.64). The programs in userland can now access the siginfo
structure. With that patch the test programs of the high resolution
timers pass without error but one which seems to also be triggered on
ix86: nanosleeps too short.

do_fork is declared as:
struct task_struct *do_fork(unsigned long clone_flags,
                            unsigned long stack_start,
                            struct pt_regs *regs,
                            unsigned long stack_size,
                            int *parent_tidptr,
                            int *child_tidptr)
ie. parent_tidptr is out4 and child_tidptr is out5, but
the comments in clone2 were suggesting otherwise.
So, we either need a patch which will codify current order
of clone arguments (ie. ptid, ctid, tls; attached below - has the advantage
that clone2 stays with the same ABI as in 2.5.[56]x), or the arguments
of clone2 and clone should be reordered to match the IA-32 order
(which is ptid, tls, ctid).

While you're fixing bitops.h, making test_bit take a const qualified
arg will kill some warnings in reiserfs...

Here's another feature I'd like to add to MCA support; the ability
to detect a flood of CMCs and switch to polling mode for retrieving
CMC logs.  Once no more CMC logs are found, return to and interrupt
driven handler.  If the flood threshold is never reached, the CMC
handler simply behaves as it does today.

   It's useful to get the CMC logs to know that something isn't
quite right, but if you end up with some bad memory it's too easy for
them to interfere with useful work.  I've tested this on an HP rx2600,
with a known bad DIMM.  This DIMM acts like it has a completely dead
DRAM on it.  With the current CMC handler, once I hit that range of
memory addresses, the system essentially dies, constantly handling
CMC errors.  With this patch, the system hits the threshold quickly,
but remains functional with no performance degredation once in polling
mode.  This patch applies against linux-2.4.20-ia64-021210 and 
includes:

 - Switching CMCs to polling mode at predeterimined threshold
 - If polling for CPEs, poll on all processors
 - Fix timestamp on log output

Andy Grover told me this should be posted here.  It allows ACPI to
compile even with PCI turned off.  Patch against 2.5.60.
