I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.

This patch adds support for shared HPET interrupts.
The driver previously acknowledged interrupts for both edge and level

necessary.

On 32-bit architectures, the multiplication in the argument for
hpet_time_div() often overflows. In the typical case of a 14.32 MHz timer,
this happens when the desired frequency exceeds 61 Hz.
To avoid this multiplication, we can precompute and store the hardware
timer frequency, instead of the period, in the device structure, which
leaves us with a simple division when computing the number of timer ticks.
As a side effect, this also removes a theoretical bug where the timer
interpolator's frequency would be computed as a 32-bit value even if the
HPET frequency is greater than 2^32 Hz (the HPET spec allows up to 10 GHz).

Change the phys_mem_access_prot() function to take a pfn instead of an
address. This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.
Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn. Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.

Some of the SN code & #defines related to compact nodes & IO discovery
have gotten stale over the years. This patch attempts to clean them up.
Some of the various SN MAX_xxx #defines were also unclear & misused.
The primary changes are:
- use MAX_NUMNODES. This is the generic linux #define for the number
of nodes that are known to the generic kernel. Arrays & loops
for constructs that are 1:1 with linux-defined nodes should
use the linux #define - not an SN equivalent.
- use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the
number of nodes in the SSI system. Compact nodes are a hack to
get around the IA64 architectural limit of 256 nodes. Large SGI
systems have more than 256 nodes. When we upgrade to ACPI3.0,
I _hope_ that all nodes will be real nodes that are known to
the generic kernel. That will allow us to delete the notion
of "compact nodes".
- add MAX_NUMALINK_NODES for the total number of nodes that
are in the numalink domain - all partitions.
- simplified (understandable) scan_for_ionodes()
- small amount of cleanup related to cnodes

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON. The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.
I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.

The device/watchdog has a fixed timeout/heartbeat.
So we don't support the WDIOC_SETTIMEOUT ioctl call
and we also may not set the WDIOF_SETTIMEOUT flag.

the attached patch moves the content of drivers/char/watchdog/i6300.h
into drivers/char/watchdog/i6300.c, since it is the only file using the
defines there is no real reason to have a separate header.

In i6300esb.c watchdog card driver were 2 bugs (misused pc_match_device and
pci_dev_put wasn't called in one error case) and one little cleanup was
done (long line was converted to a shorter one with using built-in macro).

This patch sets the WDT_ENABLE bit of the Lock Register to enable the
watchdog and WDT_LOCK bit only if nowayout is set. The old code always
sets the WDT_LOCK bit of watchdog timer for Intel 6300ESB chipset. So, we
end up locking the watchdog instead of enabling it.

I wrote earlier to the list[1] asking for a driver for the watchdog
included in the 6300ESB chipset. I got a 2.4 driver via private email
from Ross Biro which I've changed into what I hope resembles a 2.6
driver (which was done by looking a lot at the watchdog drivers
already in the 2.6 tree).
I've attached the result, and I'm hoping to get some feedback on the
coding as a first step. I can't actually test it on the hardware
right now as I won't have physical access until April. So my own tests
have been limited to "compiles-without-warnings" and
"can-be-insmodded-in-other-machine-without-oops".

This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them. The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.
