d346cce308 [PATCH] sysrq: showBlockedTasks is sysrq-W
Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the
Help message.

It was previously done via X, but X is already used for Xmon on ppc & powerpc
platforms and this collision needs to be avoided.

All callers of register_sysrq_key() are now marked in the sysrq op/key table.
I didn't mark 'h' as Help because Help is just printed for any unknown key,
such as '?'.

Added some omitted sysrq key entries in the sysrq.txt file.

41c57a8718 [PATCH] IPMI: fix timeout list handling
Fix a dangling pointer bug in ipmi_timeout_handler.  A list of timedout

6d3154cc11 Revert "[PATCH] Fix up mmap_kmem"
This reverts commit 99a10a60ba.

As per Hugh Dickins:

  "Nadia Derbey has reported that mmap of /dev/kmem no longer works with
   the kernel virtual address as offset, and Franck has confirmed that
   his patch came from a misunderstanding of what an offset means to
   /dev/kmem - whereas his patch description seems to say that he was
   correcting the offset on a few plaforms, there was no such problem to
   correct, and his patch was in fact changing its API on all platforms."

also not having a respective RNG).

f3dc07330c [WATCHDOG] pcwd_usb.c - get heartbeat from dip switches
The PCWD cards normally use the heartbeat that is set via
the dip-switches of the card. There are only 3 switches,
thus 8 combinations that each have a certain heartbeat.
The card can however be programmed with a heartbeat from
1 till 65535 seconds. This is what our driver does: it
programs the heartbeat on the card.

There are however a lot of people that don't know that
we set the heartbeat of the watchdog card to the value
provided by the heartbeat module parameter. Instead they
think that the heartbeat value is the same as set by the
dip-switches.

This patch changes the driver so that at startup you can
take the heartbeat from the dip-switches. You do this
by setting the heartbeat module parameter to 0. This
patch also makes this the default behaviour.

c41e0deb50 [AGPGART] fix detection of aperture size versus GTT size on G965
On the G965, the GTT size may be larger than is required to cover the
aperture.  (In fact, on all hardware we've seen, the GTT is 512KB to the
aperture's 256MB).  A previous commit forced the aperture size to 512MB on
G965 to match GTT, which would likely result in hangs at best if users
tried to rely on agpgart's aperture size information.  Instead, we use the
resource length for the aperture size and the system's reported GTT size
when available for the GTT size.

Because the MSAC registers which had been read for aperture size detection
on i9xx chips just cause a change in the resource size, we can use generic
code for aperture detection on all i9xx.

5aa80c7226 [AGPGART] Remove unnecessary flushes when inserting and removing pages.
This patch is to speed up flipping of pages in and out of the AGP aperture as
needed by the new drm memory manager.

A number of global cache flushes are removed as well as some PCI posting flushes.
The following guidelines have been used:

1) Memory that is only mapped uncached and that has been subject to a global
cache flush after the mapping was changed to uncached does not need any more
cache flushes. Neither before binding to the aperture nor after unbinding.

2) Only do one PCI posting flush after a sequence of writes modifying page
entries in the GATT.

	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

Replacing this with a struct pid prevents us from getting confused, and

5fcf7bb73f [PATCH] read_zero_pagealigned() locking fix
Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel
bugzilla 7645.  Right: read_zero_pagealigned uses down_read of mmap_sem,
but another thread's racing read of /dev/zero, or a normal fault, can
easily set that pte again, in between zap_page_range and zeromap_page_range
getting there.  It's been wrong ever since 2.4.3.

The simple fix is to use down_write instead, but that would serialize reads
of /dev/zero more than at present: perhaps some app would be badly
affected.  So instead let zeromap_page_range return the error instead of
BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in
that case - there's no need to optimize for it.

Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of
zeromap_page_range), though it really isn't interesting there.  And since
mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that
than -ENOMEM.

code, when moves it 4*5 columns to the right.

606d099cdd [PATCH] tty: switch to ktermios
This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

edc6afc549 [PATCH] tty: switch to ktermios and new framework
This is the core of the switch to the new framework.  I've split it from the
driver patches which are mostly search/replace and would encourage people to
give this one a good hard stare.

The references to BOTHER and ISHIFT are the termios values that must be
defined by a platform once it wants to turn on "new style" ioctl support.  The
code patches here ensure that providing

1. The termios overlays the ktermios in memory
2. The only new kernel only fields are c_ispeed/c_ospeed (or none)

the existing behaviour is retained.  This is true for the patches at this
point in time.

Future patches will define BOTHER, ISHIFT and enable newer termios structures
for each architecture, and once they are all done some of the ifdefs also
vanish.

24ec839c43 [PATCH] tty: ->signal->tty locking
Fix the locking of signal->tty.

Use ->sighand->siglock to protect ->signal->tty; this lock is already used
by most other members of ->signal/->sighand.  And unless we are 'current'
or the tasklist_lock is held we need ->siglock to access ->signal anyway.

(NOTE: sys_unshare() is broken wrt ->sighand locking rules)

Note that tty_mutex is held over tty destruction, so while holding
tty_mutex any tty pointer remains valid.  Otherwise the lifetime of ttys
are governed by their open file handles.  This leaves some holes for tty
access from signal->tty (or any other non file related tty access).

It solves the tty SLAB scribbles we were seeing.

(NOTE: the change from group_send_sig_info to __group_send_sig_info needs to
       be examined by someone familiar with the security framework, I think
       it is safe given the SEND_SIG_PRIV from other __group_send_sig_info
       invocations)

e0b79e0bc2 [WATCHDOG] watchdog miscdevice patch
It looks like the recent changes to 'struct miscdevice' have impacted
some of the Watchdog drivers.

at91rm9200_wdt.c:205: error: 'struct miscdevice' has no member named 'dev'

For the AT91RM9200 driver I just replaced "miscdevice.dev" with
"miscdevice.parent".

The mpcore_wdt.c and omap_wdt.c seem similarly affected.

4d7cbac7c8 [PATCH] IPMI: Fix BT long busy
The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets.  The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy.  The subdriver now issues
a "Get BT Capabilities" command and properly uses those results.  More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers.  Finally, indent and
other style quirks were normalized.
