The attached patch (against 2.6) helps IA-32 applications take advantage of the
generic 32 bit (fs/compat_ioctl.c) ioctl handlers.

The patch was created by Matt Helsley <matthltc at us.ibm.com> for 2.4 and
has been changed slightly to match 2.6.

The implementation compromises performance for correctness.

The attached patch implements core dump functionality for IA-32
applications running on ia64.

This kills a compilation warning if CONFIG_SMP is *not* defined.

 Based on the feedback from Tony, here's the patch that flips
around the clearing of cmc_polling_enabled.

It seems that acpi_register_intr (in arch/ia64/kernel/acpi.c)
takes an interrupt polarity/trigger in opposite way.
Attached patch fixes this.  Please apply.

drivers/acpi/resource/rsirq.c decodes ACPI extended irq
resource and stores in edge_level and active_high_low members
of a structure (BTW, I think the names of these members
are source of confusion ;).

And this logic in acpi.c inverts both polarity and trigger.

vector = iosapic_register_intr(gsi,
        polarity ? IOSAPIC_POL_HIGH : IOSAPIC_POL_LOW,
        mode ? IOSAPIC_EDGE : IOSAPIC_LEVEL);

       ACPI -> rsirq.c -> serial.c -> acpi.c            -> iosapic.c
High      0         0           0      IOSAPIC_POL_LOW
Low       1         1           1      IOSAPIC_POL_HIGH
Edge      1         0           0      IOSAPIC_LEVEL
Level     0         1           1      IOSAPIC_EDGE

As ACPI_ACTIVE_{HIGH,LOW} and ACPI_{LEVEL,EDGE}_SENSITIVE are
defined in acpi subsystem, it should be safer to use these symbols.

Here's a redesign of the CMC and CPE polling for both 2.6.0-test2
and 2.4.21.  This is roughly the same design I requested comment on
a while back (BTW, nobody commented...).  Basically, rather than
flooding all the cpus in parallel, I used some low priority interrupts
to cascade through the cpus.  This should be much more scalable.  I
also added a new feature of enabling interrupts for the CMC and CPE
handlers.  The SAL spec claims these functions are SMP safe and
re-entrant and even recommends that the corrected error handlers
should run with interrupts enabled.  It works on HP boxes, others
might want to double check that their firmware adheres to the spec.
The combination of these things should keep polling from impacting
system response time.

also detach the threads.

Otherwise we'll leave them around as zombies, waiting for them
to be picked up by their parent. Which might be the execve()
thread itself, causing a deadlock.

Noted by Sean Estabrooks:

There is a bug in "ll_rw_blk.c" handling partial bvec submissions.
For whatever reason the floppy driver was triggering it more than
other users (most likely because most other devices tend to be able
to always complete a full request in one go).

Fixed by updating the proper bio vector index entry.

Add kconfig options to allow excluding either or both the I/O
schedulers.  This can be useful for embedded systems (saves about ~13KB).

All schedulers are enabled by default for non-embedded.

This updates the valkyriefb driver to the new API.

From Paul Mackerras <paulus@samba.org>:

 "It compiles OK, but I haven't been able to test it.  I have simplified
  the driver quite a bit using the knowledge that there can only ever be
  one valkyrie graphics adaptor in a system - it is the built-in
  graphics adaptor on various ancient mac and powermac machines, and we
  access it at a hard-coded address, so we can only handle one."

Documentation/nmi-watchdoc.txt doesn't actually tell what options need to be
enabled in kernel config in order to use NMI watchdog. I for one found it
confusing.

Rename ariadne2 to zorro8390, since this driver supports several NS8390-based
Zorro Ethernet cards. Kill all never used occurrencies of CONFIG_NE2K_ZORRO.

m68k cache updates (from Roman Zippel):
  - Uninline flush_icache_range()
  - Add virt_to_phys_slow() which handles vmalloc()ed space

M68k: Use genrtc on all m68k platforms

M68k: Allow ALLOWINT to be used with other types than short (fixes a problem
with irqs_disabled(), from Roman Zippel)

dmasound: Implement missing SOUND_PCM_READ_RATE ioctl (from Richard Zidlicky)

MIPS: Show the correct logo on DEC and SGI machines.

M68k FPU emulator: Add fgetman, fgetexp and fsqrt (from Michael Müller and
Roman Zippel)

M68k: A few missing updates to the new irq API:
  - Q40/Q60 keyboard
  - Q40/Q60 floppy
  - Sun-3x floppy

m68k page updates (from Roman Zippel):
  - Set _PAGE_RONLY bit and clear _PAGE_PRESENT to mark PAGE_NONE pte entries
    (this also makes PAGE_NONE fixup unnecessary)
  - Move _PAGE_FILE to a lower, so pte_to_pgoff/pgoff_to_pte becomes simpler

NCR53C9x: Remove unused initialization of SCp.have_data_in (from Maciej W.
Rozycki). This affects the following drivers:
