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.

elv_iosched_store doesn't terminate string passed from userspace if it's too long. Also, if the written length is zero (probably not possible), it accesses elevator_name[-1]. This patch fixes both bugs. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJens Axboe <axboe@suse.de>

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. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJens Axboe <axboe@suse.de>

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.

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. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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 some benchmarks and found nothing interesting. Performance has consistently fallen within the noise range. It also introduces a config option (setting the default to 3 levels). The config option prevents having 4 level page tables with 64k base page size.
