Since smp_stop_cpu is not used, we don't need to test for it.  This
saves several instructions in the IPI handler and simplifies the code.

There are no longer any callers of GET_PROCESSOR_MID and
GET_PROCESSOR_ID, so both are removed.

Recent tools are disregarding both the __asm__(".text") in init_task.c
and the alignment at the end of .text in head.S.  Use attributes
instead.

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.)

Version 1.14 of pcwd.c - Changes that were made are:
* Extract the start code in a seperate function (pcwd_start)
* Extract the stop code in a seperate function (pcwd_stop)
* Extract the get_temperature code in a seperate function (pcwd_get_temperature)
* Make /dev/watchdog and /dev/temperature to different misc devices with their own fops
* Small clean-up's

Tested on pcwd card with temperature option.

Version 0.07 of softdog.c - Changes that were made are:
* Extract the start/keepalive code in a seperate function (softdog_keepalive)
* Extract the stop code in a seperate function (softdog_stop)
* Add notifier support
* Extract softdog_set_heartbeat code to seperate subroutine
* Small clean-up's

Cleanup header file after changes to wdt.c and wdt_pci.c

Version 0.10 of wdt_pci.c - Changes that were made are:
* Extract the start code in a seperate function (wdtpci_start)
* Extract the stop code in a seperate function (wdtpci_stop)
* Convert wdtpci_ping so that it return an int value (0=succes).
* Extract the get_temperature code in a seperate function (wdtpci_get_temperature)
* Make /dev/watchdog and /dev/temperature to different misc devices with their own fops.
* Reorganize init and exit functions
* Make heartbeat (the emulated heartbeat) a module parameter
* Rewrite status flag code so that we could add a new tachometer module parameter
   + make clear distinction between PCI-WDT500 and PCI-WDT501.
* Small clean-up's

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.
