Rename the driver hooks in the DRM to something a little more understandable:
preinit -> load
postinit -> (removed)
presetup -> firstopen
postsetup -> (removed)
open_helper -> open
prerelease -> preclose
free_filp_priv -> postclose
pretakedown -> lastclose
postcleanup -> unload
release -> reclaim_buffers_locked
version -> (removed)
postinit and version were replaced with generic code in the Linux DRM (drivers
now set their version numbers and description in the driver structure, like on
BSD). postsetup wasn't used at all. Fixes the savage hooks for
initializing and tearing down mappings at the right times. Testing involved at
least starting X, running glxgears, killing glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128)
Linux (r200, savage4)

AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i
spurely an x86'ism. The proper AGP mapping flusher that should be used
is "flush_agp_mappings()", which on x86 obviously happens to do a global
TLB flush.
This makes AGP (or at least the config _I_ happen to use) compile again
on ppc64.

AGP allocation/deallocation is suffering major performance issues due to
the nature of global_flush_tlb() being called on every change_page_attr()
call.
For small allocations this isn't really seen, but when you start allocating
50000 pages of AGP space, for say, texture memory, then things can take
seconds to complete.
In some cases the situation is doubled or even quadrupled in the time due
to SMP, or a deallocation, then a new reallocation. I've had a case of
upto 20 seconds wait time to deallocate and reallocate AGP space.
This patch fixes the problem by making it the caller's responsibility to
call global_flush_tlb(), and so removes it from every instance of mapping a
page into AGP space until the time that all change_page_attr() changes are
done.

We must poll for responses to commands when interrupts aren't in use. The
default poll interval is based on using a kernel timer, which varies with HZ.
For character-based interfaces like KCS and SMIC though, that can be way too
slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve
the sensor list).
This creates a low-priority kernel thread to poll more often. If the state
machine is idle, so is the kernel thread. But if there's an active command,
it polls quite rapidly. This decrease a firmware flash time from 15 minutes
to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge
x8x system.
The timer-based polling remains, to ensure some amount of responsiveness even
under high user process CPU load.
Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to
ensure safe stoppage.

BMCs can get into ERROR0 state while flashing new firmware, particularly while
the BMC is erasing the next flash block, which may take a just under 2 seconds
on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the
single-threaded firmware may not be able to process new commands. In
particular, clearing OBF may not take effect immediately.
We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to
actually be clear before proceeding.
This introduces a new return value from the LLDD's event loop,
SI_SM_CALL_WITH_TICK_DELAY. This means the calling thread/timer should
schedule_timeout() at least 1 tick, rather than busy-wait. This is a longer
delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

The current BT retry/reset mechanism fails to succeed on a PowerEdge 1650,
when the controller is wedged with B2H_ATN asserted at XACTION_START. If this
occurs, no further commands will ever succeed unless the state of the
controller is first cleared out.
Furthermore, the soft reset would only occur if the first command after insmod
was the one that timed out, not if a later command timed out.
This patch changes the retry/reset mechanism to be as follows:
Before retrying a command, clear the state of the BT controller such that the
flags represent ready for a new transaction. This increases the chance of
success of the restarted transaction.
After 2 retries, issue a soft reset and retry one more time before giving up
and reporting back a failure.

succeeds.
This patch adds general infrastructure for receiving commands before they're
passed down to the low-level drivers, such that they can be completed
immediately, or modified, prior to being sent to ->start_transaction().

A number of small changes for the various system interface drivers,
consolidated from a number of patches from Matt Domsch.
Clear B2H_ATN and drain the BMC message buffer on command timeout. This
prevents further commands from failing after a timeout.
Add bt_debug and smic_debug module parameters, expose them in sysfs. This
lets you enable and disable debugging messages at runtime.
Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed
to ->event() after jiffies wrap-around. The BT driver had caught this, but
didn't know how to fix it. Now all calls to ->event() use a sane value for
time.
Increase timeout for commands handed to the BT driver from 2 seconds to 5
seconds. This is necessary particularly when the previous command was a
"Clear SEL", as that command completes, yet the BMC isn't really ready to
handle another command yet.
Silence BT debugging messages which were being printed on the console.
Increase SMIC timeout form 1/10s to 2s. This is needed on Dell PowerEdge 2650
and PowerEdge 750 with ERA/O cards to allow commands to complete without
timing out.
Adds kcs_debug module param, to match behavior of BT and SMIC. This also
prevents messages from being sent to the console unless explicitly requested.

This patch is rather large, but it really can't be done in smaller chunks
easily and I believe it is an important change. This has been out and tested
for a while in the latest IPMI driver release. There are no functional
changes, just changes as necessary to convert the locking over (and a few
minor style updates).
The IPMI driver uses read/write locks to ensure that things exist while they
are in use. This is bad from a number of points of view. This patch removes
the rwlocks and uses refcounts and RCU lists to manage what the locks did.

I recently picked up my older work to remove unnecessary #includes of

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

adding #includes, and all hunks are independent of each other. So if any

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).

Since the tpm does not have it's own pci id we have been consuming the lpc

This patch removes the dependency on pci_dev from tpm.c The subsequent patches

This patch is in preparation of supporting chips that are not necessarily on

The trick I used is to move f_rcuhead and f_list in an union called f_u

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.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

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

On a vc resize, the contents of the old screen buffer are transferred to the
new screenbuffer. If the new screenbuffer is smaller than the old one, only
the contents from the bottom are copied to new. If the contents of the old
buffer are located at the top, then the contents will not be copied to the new
buffer resulting in a blank screen.
This bug will happen only if the vc in question is not in the foreground.
Doing an fbset -a or con2fbmap will trigger this bug.
To fix this problem, base the start of the copy from the location of the
current cursor. If the cursor is near the top of the buffer, copy the
contents at the top, and if the cursor is near the bottom of the buffer, then
copy the contents at the bottom. In the unlikely case where the new row size

In order for the RCU to work, the file table array, sets and their sizes must
be updated atomically. Instead of ensuring this through too many memory
barriers, we put the arrays and their sizes in a separate structure. This
patch takes the first step of putting the file table elements in a separate
structure fdtable that is embedded withing files_struct. It also changes all
the users to refer to the file table using files_fdtable() macro. Subsequent
applciation of RCU becomes easier after this.

The idea of this patch is to lock both sides of a ptmx/pty pair during line
discipline changing. This is needed to ensure that say a poll on one side of
the pty doesn't occur while the line discipline is actively being changed.
This resulted in an oops reported on lkml, see:
http://marc.theaimsgroup.com/?l=linux-kernel&m=111342171410005&w=2
A 'hacky' approach was previously implmemented which served to eliminate the
poll vs. line discipline changing race. However, this patch takes a more
general approach to the issue. The patch only adds locking on a less often
used path, the line-discipline changing path, as opposed to locking the
ptmx/pty pair on read/write/poll paths.
The patch below, takes both ldisc locks in either order b/c the locks are both
taken under the same spinlock(). I thought about locking the ptmx/pty
separately, such as master always first but that introduces a 3 way deadlock.
For example, process 1 does a blocking read on the slave side. Then, process
2 does an ldisc change on the slave side, which acquires the master ldisc lock
but not the slave's. Finally, process 3 does a write which blocks on the
process 2's ldisc reference.
This patch does introduce some changes in semantics. For example, a line
discipline change on side 'a' of a ptmx/pty pair, will now wait for a
read/write to complete on the other side, or side 'b'. The current behavior
is to simply wait for any read/writes on only side 'a', not both sides 'a' and
'b'. I think this behavior makes sense, but I wanted to point it out.
I've tested the patch with a bunch of read/write/poll while changing the line
discipline out from underneath.
This patch obviates the need for the above "hide the problem" patch.

The ipmi driver does not have a way to handle firmware-generated events
which have the OEM[012] Data Available flags set. In such a case, the
SMS_ATN bit may never get cleared by firmware, leaving the driver looping
infinitely but never able to make any progress.
This patch first simplifies storage and use of the data returned from an
IPMI Get Device ID command.
It then creates a new per-OEM handler hook, which should know how to handle
events with the OEM[012] Data Available flags set. It then uses this to
implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which
are susceptable to setting the OEM[012] Data Available flags when the
driver can't handle it.

It might be possible for the saved pointer (*p) to become invalid in
between vc_resizes, so saving the screen offset instead of the screen
pointer is saner.
This bug is very hard to trigger though, but Andre probably did, if he's
submitting this patch. Anyway, with Andre's patch, it's still possible for
the offsets to be still illegal, if the new screen size is smaller than the
old one. So I've also added checks if the offsets are still within the
screenbuffer size.

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level. The timer has implementation dependent timeout frequencies
that can be configured by software.
One the first Watchdog timeout we get a critical exception. It is left to
board specific code to determine what should happen at this point. If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.
Command line parameters:
wdt=0 : disable watchdog (default)
wdt=1 : enable watchdog
wdt_period=N : N sets the value of the Watchdog Timer Period.
The Watchdog Timer Period meaning is implementation specific. Check
User Manual for the processor for more details.

2. Open the driver and close it without writing 'V' before close.
3. Unload the module. The timer will continue to run...
4. Oops happens when timer fires.

Fix is easy: always take a reference on the module on open.
Release it only when the device is closed and no timer is running.
Tested on 2.6.13-rc6 using the soft_noboot option. While the
timer is running and the device is closed, the module use count
stays at 1. After the timer fires, it drops to 0. Repeatedly
opening and closing the driver caused no problems. Please apply.
