This patch adds a new function, sbusfb_compat_ioctl() to
drivers/video/sbuslib.c and uses it as compat_ioctl in all sbus fb
drivers
This remove the last per-arch compat ioctl bits in
arch/sparc64/kernel/ioctl32.c so it would be nice if people could test
if this actually copiles and works and if yes apply it :)

We had similar problems with other ioctls where userspace did things
like that. What we did there was to put the compat handler to generic
code. The patch below does that, adding a big comment about what's
going on and removing the COMPAT_IOCTL entires for these on powerpc
that not only weren't ever useful but are duplicated now aswell.

With generic dispatch queue update, implicit former/latter request
handling using rq->queuelist.prev/next doesn't work as expected
anymore. Also, the only iosched dependent on this feature was
noop-iosched and it has been reimplemented to have its own
latter/former methods. This patch removes implicit former/latter
handling.

The original implementation directly used dispatch queue. As new
generic dispatch queue imposes stricter rules over ioscheds and
dispatch queue usage, this direct use becomes somewhat problematic.
This patch reimplements noop-iosched such that it complies to generic
iosched model better. Request merging with q->last_merge and
rq->queuelist.prev/next work again now.

This patch adds request_queue->nr_sorted which keeps the number of
requests in the iosched and implement elv_drain_elevator which
performs forced dispatching. elv_drain_elevator checks whether
iosched actually dispatches all requests it has and prints error
message if it doesn't. As buggy forced dispatching can result in
wrong barrier operations, I think this extra check is worthwhile.

I got a panic in the elevator code, backtrace :
Unable to handle kernel NULL pointer dereference at virtual address 00000060
..
EIP is at elevator_put+0x0/0x30 (null elevator_type passed)
..
elevator_init+0x38
blk_init_queu_node+0xc9
floppy_init+0xdb
do_initcalls+0x23
init+0x10a
init+0x0
Clearly if the kmalloc here fails, e->elevator_type is not yet set; this
appears to be the correct fix, but I think I probably hit the second case
due to a race condition. Someone more familiar with the elevator code
should look at this more closely until I can determine if I can reproduce.

Although according to the documentation this largely only affects
desktop LED control, let's make sure we set the ATAPI bit when we
have an ATAPI device attached to the port.
|
|
Don't directly reference qc->n_elem, as that might cause an off-by-one
error for misaligned (padded) ATAPI transfers.

As per the new release rules: two weeks of merging, and then an -rc1 and

On ia64, it is possible to get NaT Consumption Fault and a kernel panic
when initializing sctp sideeffect commands arguments. The union
sctp_arg_t contains different sized elements and when loading a smaller
sized element (32 or 16 bits), it is possible for a speculative load to
fail and result in a NaT bit set which causes a kernel crash. The easy
way to get around it is to load the largerst member of the union.

It is possible to get to sctp_v4_get_saddr() without a valid
association. This happens when processing OOTB packets and
the cached route entry is no longer valid.
However, when responding to OOTB packets we already properly
set the source address based on the information in the OOTB
packet. So, if we we get to sctp_v4_get_saddr() without an
association we can simply return.

After the last merge of the new unified 'powerpc' architecture, ppc64 no
longer compiles cleanly as a standalone architecture. Some bits and
pieces still exist as files under the old ppc64 hierarchy, but the old
"ARCH=ppc64" is dead.
So if "uname" says ppc64, that now implies that the default architecture
should be "powerpc".

Noticed by Tom 'spot' Callaway.
Even on uniprocessor we always reported the number of physical
cpus in the system via /proc/cpuinfo. But when this got changed
to use num_possible_cpus() it always reads as "1" on uniprocessor.
This change was unintentional.
So scan the firmware device tree and count the number of cpu
nodes, and report that, as we always did.

Fix default VGA console on SN platforms. Since SN firmware does not pass
enough ACPI information to identify VGA cards and the associated legacy IO/MEM
addresses, we rely on the EFI PCDP table. Since the linux pcdp driver is
optional (and overridden if console= directives are used) SN duplicates a
portion of the pcdp scan code to identify if there is a usable console VGA
adapter. Additionally, dup necessary pcdp related structs to avoid dragging
drivers/pcdp.h into a more public location.

This patch introduces 4-level page tables to ia64. I have run

It also introduces a config option (setting the default to 3

tables with 64k base page size.
