Semaphores use 24-bit atomics, not 32.  Using the wrong initializer
causes immediate deadlock under SMP, and incorrect results under UP.

For some reason I don't understand, the last UDF filesystem update makes
the UDF deadlock when I write a bunch of mp3 files to a CDRW using the
packet writing patch.  Both "cp" and pdflush get stuck in __down. 

Reverting the semaphore changes makes the problem go away.  Use the
kernel lock again, until whatever recursive offender gets fixed.

(The offensive recursion seems to be: write() takes the inode semaphore,
causes memory pressure, and then trying to write back the inode or dirty
data to disk tries to get the semaphore again and deadlocks.)

Use tasklet instead of workqueue for the divas main dpc.

Restructered the CAPI code of list handling and lock.

Removed obsolete code.

2.4 patch from Adrian Bunk.

ERRORS

    The mprotect() function shall fail if:

    ...

    [ENOMEM]
        Addresses in the range [addr,addr+len) are invalid for the
        address space of a process, or specify one or more pages which are
        not mapped.

Quick fix to work around gcc3.5's automatic inline and broken stack
requirements calculation. Without this, I see stack overflows at boot
with 4k stacks.

Kernel 2.6 lacks two -EFAULT returns in get_user() in kernel/sysctl.c.

Opening a non-existing block device currently yields an ENXIO error.  Doing
the same for char devices produces the correct error ENODEV.

In the i386 case we need to generate asm-offset.h, before starting building
the kernel tree.  Building asm-offset.h causes us to use one of the
shorthands in the top-level makefile, namely the one for .s files.  The one
that allows us to do: make some/dir/file.s

And this shorthand happens to have a dependency to scripts, therefore I did
not see this problem on i386.  But David hit it with sparc64, because there
is no asm-offset.h file.  No parallel stuff involved here, just an ordinary
error.

It's now called from the CPU hot-add notifier.

fusion needs several separately allocated coherent regions and
requires that they all be in the same 4GB segment.  Obviously this may
fail.  The hack is to force the coherent_dma_mask to 0xffffffff thus
ensuring that all the allocations occur within the first 4GB.  This
hack breaks Altix entirely.

ISAPnP support has been stable with the new pnp layer for a while.
This patch removes the experimental dependency.

This patch allows the serial driver to bind to three additional modems.

isapnp_cfg_begin and isapnp_cfg_end are exported symbols, so if any
module using them is loaded isapnp.o can't be unloaded anyway

// Linux 2.6.4-rc2
// These 2 functions shouldn't be __init for general PNP use

This patch fixes a bug in the resource configuration function.  If
there are more than one memory ranges, the isapnp driver will write
into the incorrect configuration register.

This is an improved version of the G4 "windtunnel" fan controller.  It
depends on the keywest bugfix...

This fixes a deadlock in I2C probing.

 - keywest holds the pmac_low_i2c_lock while registering the i2c adapter.
 - i2c_add_adapter() notifies registered drivers by calling
   driver->attach_adapter().
 - a driver might access the i2c bus from attach_adapter() which
   deadlocks since all xfer routines take the lock.

Attached is a patch to fix an oops in sg_cmd_done. Please apply.

remove dependency on kobj.name.

One more missing doc-file update

Three quarters of the update from Andi was uncommitted due to a bad
patch date and a bug in "bk import -temail"..

Here are the missing parts..

Fix token pasting to work with older gcc versions.

We need a space before the "," that may get pasted away.

Finally nailed this sucker.

con_close() checks the tty->count and then sleeps in acquire_console_sem().
But another process can come in and grab a ref against the tty while
con_close() dropped the BKL.  But con_close() then proceeds to deallocate the
tty->driver_data anyway, even though the tty now has ->count == 2.

Fix that by moving the check for ->tty_count inside console_sem.

There were some nasty bugs in the x86-64 code, including one race that
could cause random reboots, especially on Intel machines, with the NMI
watchdog.  This patch fixes them and also includes some harmless
cleanups.

Main fixes were for some buglets in the IOMMU code and the plugging of a
race in the exception stack handling.  Also disables an broken MCE on K8
explicitely.

Also finally the preempt compile issues are fixed.

 - Declare hpet interrupt separately in drivers/char/rtc.c
 - Fix rtc.h/hpet.h to not depend on interrupt.h
 - Finally include smp_lock.h in hardirq.h
 - Update defconfig
 - Export bad_dma_address
 - Merge with 2.6.5rc2
 - Never schedule on interrupt stacks.
 - Add option to force software iotlb (iommu=soft)
 - Add ifdefs to gsi patch to match i386 (Bjorn Helgaas)
 - Fix K8 GART TLB MCE workaround to actually work
 - Fix dwarf2 unwind table in SAVE_ARGS (Jim Houston)
 - Disable APIC on VIA/NVidia even with acpi=off (Gwenole Beauchesne)
 - Fix parsing bug in "apic" option (Gwenole Beauchesne)
 - Fix dma mask handling in pci_alloc_consistent
 - Make pci_alloc_consistent more robust in low memory situations.
 - Print version number in oopses (from i386)
 - ACPI GSI cleanup (Bjorn Helgaas)
 - Disable K8 GART TLB walk error MCE explicitely
 - Add support to disable individual MCEs in the various banks.

The fan driver I wrote for adt746x looks like it only handles the adt7467
chip found in iBooks G4; but it also handles the adt7460 chip found in the
Powerbook G4 Alu.  Here's a patch that updates therm_adt7467.c, Kconfig and
Makefile.

Some isapnp devices were not getting detected as a result of a bug in the isapnp
driver.  It was not following the specifications and calculating a checksum when
it was not reliable.  This problem was originally discovered by Paul L. Rogers
<rogerspl@datasync.com>.  He made an initial patch.  This release has some small
modifications, including a check to see if we run out of CSNs.
